Best Cordless String Trimmers: Your Easy Buying Guide (Updated!)

Whether you call it a weed whacker, weed eater, or even a Destructroweed 3000, a string trimmer is an essential tool in your landscaping arsenal. Paired with the right lawn mower, your string trimmer will allow you to take care of all the pesky details of your yard.

Gas-powered and corded electric models have been around for a long time. Gas trimmers have typically provided superior power and efficiency (along with the most noise and fumes). I’m here to tell you the days of gas trimmer dominance are over.

Battery-powered weed eaters now offer up enough sustained electric power and torque to rival the biggest, baddest gas trimmers on the block. And that’s without making a total racket or producing nasty exhaust fumes. On top of that, many vendors offer a platform of tools that share the same batteries making for some seriously streamlined landscaping.

EGO Power ST1504SF 15-Inch Foldable Shaft String Trimmer

Ego Power does one thing: make great electric power tools. I’ve looked at their lawn mowers and they make a persuasive argument to upgrade to electric yard maintenance equipment. The EGO Power ST1504SF 15-Inch Foldable Shaft String Trimmer will simply pile on that argument, twisting your arm behind your back until you seriously give consideration to electric-only equipment. The ST1504 uses a 56V brushless motor for quiet, powerful performance and comes packaged with a 5Ah battery. A 2.5Ah package is also available. I have an average-sized yard so I’m sure at 30 minutes of run time that the 2.5Ah would be fine. But I hate waiting for charging batteries more than I like saving a buck so I’d go with the 5Ah package. Plus it’s a better deal when considering 5Ah batteries cost 250!

The Rapid Reload head is a very slick idea, simply thread your line through the head and twist it to wind it in. No fuss, no muss. The trimmer shaft is made of carbon fiber and comes with a lifetime guarantee on top of the five-year warranty and the three-year battery warranty. Sixty minutes of trimming using the Ego Power ST1504 is going to be more than enough for pretty much any yard but since the batteries are interchangeable with other Ego products, you could finish trimming then slap that battery into a leaf blower or another tool and keep going.

I’m a fan of Ego Power and what they’re doing. Their newest products outperform gas models in a big way and they’ve recently been hinting at a battery-powered riding lawn mower coming out in 2021. They get electric yard tools and based on the ST1504 cordless electric string trimmer, you would be wise to consider grabbing one of these for your yardwork arsenal.

Makita XRU15PT1 LXT Cordless Electric String Trimmer

Makita arguably makes the finest power tools on the planet however they are expensive. Some will say that the cost is justified because they are simply that good. Others will make do with a lesser brand to save money. The Makita XRU15PT1 LXT Cordless Electric String Trimmer goes a long way to demonstrate why, while it may cost a lot, it deserves your consideration as the indispensable yard care tool you may own.

This kit includes two 18V 5Ah batteries which is a great deal in itself. Makita also offers a kit with four (that’s right, FOUR) 18V 5Ah batteries. Stop and consider that for the approximate 150 more than the bare tool, Makita is throwing in four 18V 5Ah batteries and a dual charger with a 45-minute charge time. Purchasing these items separately will cost you close to 400! If you own or are considering buying other Makita tools, this is a steal.

Like their LXT lawn mower, this trimmer offers up some serious power utilizing two 18V batteries for a full 36V power load. That’s 90 minutes of run time. That’s right. You heard me. Ninety. Minutes. You could trim the entire block with that kind of power.

There are three speed options to give you what you need for power management depending on what you have to cut down. Not sure what speed you will require? Don’t worry: automatic torque drive tech automatically shifts between 3,500 and 6,500 RPM for added power through thick brush and turf. 15 inches of cutting diameter will make short work of that overgrown grass that’s been laughing at you.

The bottom line is this: Makita’s LXT String Trimmer is durable, tough, balanced, and awesome. It’s like this tool is that trusty dog you had as a kid that just wants to go out and have fun. It’s practically begging you to go outside and decimate the weeds. Go get ’em.

Milwaukee M18 Fuel Cordless Electric String Trimmer with Quik-Lok

Like their other power tools that are top-quality and deliver great performance, the M18 Fuel Cordless Electric String Trimmer from Milwaukee has the power to clear thick brush, reaches full throttle in less than a second and delivers up to 60 minutes of running time. The M18 Fuel comes packaged with an 18V 8Ah battery and charger. This trimmer is one of the few I’ve seen that comes with a battery that large. On top of that, the charge time is only an hour. For an 8Ah battery. That’s AWESOME.

The M18 Fuel features a “Quik-Lok” system that allows for multiple attachments like a lawn edger, hedge trimmer, and pole saw. This system was definitely made to meet the needs of professional landscape maintenance with a brushless electric motor. It’s big, it’s bad, it’s going to scare whatever brush and weeds you have back to the Stone Age. It’s so big and bad that you may want to consider picking up a shoulder strap to help you maneuver this beast if you’re a smaller person.

Yes, the Milwaukee M18 Fuel Cordless String Trimmer is more expensive than other trimmers but you must consider a few things. First, Milwaukee tools are incredibly good. Second, the battery is massive and charge time is extremely low. Third, this tool will save you more time and trouble than any other model. I would be hard-pressed to find a better cordless electric string trimmer out there. It’s really that good.

Oregon ST275 Cordless Electric String Trimmer

Oregon is primarily known for its quality line of chainsaws for both the professional and consumer market. They also have a family of 40V battery-powered products including lawn mowers, hedge trimmers, and more including the Oregon ST275 Cordless Electric String Trimmer. A 4Ah battery and charger is provided with the unit that will give approximately 30-40 minutes of operational time on a full charge. The trimmer weighs less than 10 pounds and may be converted to an edger with a simple flip of the guard. It’s a very good tool for your yard.

Here’s where this cordless electric string trimmer breaks away from the pack: Oregon includes a “Gator SpeedLoad” trimmer head that uses pre-loaded disks of cutting line. No winding, twisting, or taking the head off to load up more string here. Simply uncap the trimmer head, insert the disk, and re-attach. This process can be done in 20 seconds or less. That’s a unique idea in the world of string trimmers.

When I first looked at this setup, I was skeptical because proprietary disks of string are going to be more expensive than a bulk spool. A ten pack of.080-inch trimmer line disks is more expensive than your average bundle of.080″ string however the tongue-and-groove design of the Oregon string should last roughly twice as long. It’s really up to you how much you want to waste time loading string into your trimmer.

Snapper XD 82V MAX Cordless Electric String Trimmer

I really enjoyed looking at the Snapper XD 82V MAX 21-inch cordless electric lawn mower earlier this year. It’s powerful, looks sharp, and is more than a match for a gas mower. The Snapper XD line includes a number of great machines including this companion to the mower, the Snapper XD 82V MAX Cordless Electric String Trimmer that share the same family of large batteries. I’m happy to say that this trimmer is the perfect addition to use alongside the Snapper mower.

82 volts of power can do significant damage to those dastardly weeds without the kickback and flying debris that frequently accompany gas-powered weed eaters. I was concerned about how long a 2Ah battery could go but the 30 minutes of operational time is good enough for a half-acre of shaving around the perimeter and various flower beds and trees. Still, if you don’t already have the Snapper mower, I recommend keeping an extra battery on hand just in case.

The dual-line, bump-feed head can handle cutting just about anything down short of larger bushes and is easy to restring. Snapper makes several attachments for this trimmer including a hedge trimmer, cultivator, and pole saw. Swapping out the trimmer head with one of the others is essentially painless. This Snapper line is really impressive with its 82V batteries and the mix and matching you can do with the family of tools.

Craftsman V20 Cordless Electric String Trimmer Edger

Ah, Craftsman. Just the name makes me think of Apple pie and fireworks on the Fourth of July. Their cordless electric string trimmer, the Craftsman V20, comes packaged with a 20 Volt 4Ah battery and charger that should give you enough life to edge and trim your medium-sized yard, around 30 to 40 minutes of run time. The line feed adjustment is managed through a button near the throttle instead of bumping the cutting head. High and low settings allow for serious cutting when you need it but the running low will take care of just about anything you need save for tall, thick turf.

The Craftsman V20 (I like the marketing decision of putting the V for Volts in front of the 20, making it sound like an engine) only has a 13-inch cut swath but for the average homeowner, that’s probably okay. The support handle and pole length are both adjustable depending on your build. A cutting guard (colored red…nice) will help protect your delicate flowers and your string from making contact with bricks and trees.

V20 batteries are interchangeable with other Craftsman tools but be aware that the battery that comes with this trimmer may not fit your older Craftsman V20 tools. Craftsman also doesn’t fool around with manufacturing a central machine that accommodates separate attachments like hedge trimmers and pole saws. One tool for one job, sir, however a dedicated tool is not necessarily a bad thing. And while one battery should be enough for what you’re doing with the trimmer, you may want to pick up another battery in case you have a long day of trimming planned or you have other Craftsman V20 tools. For whatever reason, it’s cheaper to purchase a 20V 4Ah battery separately than the bundle with two batteries. Go figure.

DeWALT DCST920B Cordless Electric String Trimmer

The DeWALT DCST920B 20V MAX Cordless Electric String Trimmer is part of the large power tool line that utilizes 20V MAX batteries from DeWALT. Like other brands, the batteries are proprietary and only fit DeWALT 20V tools. The motor is brushless to maximize efficiency and durability. This trimmer uses a dual.080″ line, bump-feed head with a 13-inch cutting diameter.

RYOBI 18V ONE 13″ String Trimmer/Edger

A variable trigger offers speed control depending on your conditions. It is calibrated nicely to control the power, even better than some gas-powered trimmers. DeWALT claims they have a patented gear drive design that provides more torque and maintains cut speed when plowing through thick vegetation. For its size and power, this definitely seems to be the case.

Unfortunately, DeWALT only offers this trimmer on its own without any sort of bundle package. You’ll have to pick up this battery starter kit including two 5Ah batteries and a charger. The charger can handle 12V, 20V, and 60V capacities and also includes a soft tool bag.

DeWALT has a reputation of producing high-quality tools and this cordless string trimmer is no exception. Lightweight and compact, the DCST920B is a great string trimmer for almost any environment.

Note: I need to report something that came up a few times during my research for this review. Some users of the DeWALT DCST920B have reported issues with the string head. Apparently DeWALT offers up four types of design and the one that comes with this model, Type 4, doesn’t have a divider for each side of the chamber making the string prone to snags during operation. I don’t think this is a deal-breaker but it’s good to know just the same.

WORX GT 3.0 20V Power Share Cordless String Trimmer Edger

This model, the Worx GT 3.0 Cordless String Trimmer Edger, is part of the “PowerShare” line of Worx tools that share the same series of batteries and offer a less expensive option to other yard machines out there. Worx has carved themselves a niche between the bargain basement appeal of Sun Joe and the more professional Ryobis and Milwaukees of the world. This trimmer is economical and is one of the few that comes packaged with two batteries (they’re weaker at only 2Ah, but you could still keep one in the charger ready to go). If you decided to pick up a third, they’re inexpensive enough that your budget is kept intact.

Motor performance is excellent. The trimmer is lightweight (less than six pounds) and offers just a 12-inch cutting diameter so this is a particularly good option for people who may be smaller or have challenges using a professional machine. Feeding line into the spool head is easy enough that pretty much anyone can do it without effort. If your line is getting short, use the “Command Feed” push button near the throttle trigger to get more without bumping the trimmer head. The string that comes with the trimmer is not of the greatest quality; consider upgrading to a better product.

The support handle adjusts for varying heights and your own particular comfort level. A spacer guard acts as a visual for the user and protects plants and obstacles against errant damage. If you’re feeling crazy, shove it back in the trimmer head and go wild. The head also pivots 90 degrees to get under that playset or to attack those hills that need trimming STAT.

When you’re ready to convert from trimming to edging, simply unlock the buckle on the shaft, turn the cutting head, and lock it back. You can do it in under five seconds, seriously. I’m not a huge fan of using string trimmers to edge however for small areas, the Worx GT 3.0 would do a decent job of cleaning up that grass to sidewalk division.

The package consisting of trimmer, string, batteries, and charger costs less than 100. For anyone considering getting into a cordless electric string trimmer, you could do a lot worse than giving this a shot. Given the multiple positive reviews from users online, Worx has created a solid machine.

Ryobi 40 Volt Attachment Capable Cordless String Trimmer

Disclaimer: I own a Ryobi gas-powered string trimmer and I love it. It’s powerful, easy to use, and I swap the trimmer head with the edger head on a regular basis when maintaining my yard. Other than putting up with a gas tank that’s awkward to fill, I love the thing. This model, the Ryobi 40 Volt Attachment Capable Cordless String Trimmer is as good or better than the gas-powered model with none of the hassle of spilling gas all over the place (I’m embarrassed to say that it’s happened more often than I care to mention).

Part of the 40 Volt family of cordless electric products from Ryobi, this trimmer comes with a 4Ah battery (and charger) good enough to mow down an acre’s worth of perimeter on one charge. I don’t have nearly that much to take care of so the battery packs more than enough juice for me to edge the grass and trim in one go. Keep in mind that your first couple of sessions will last shorter until you break in your battery. It will take 90 minutes on average to fully charge the battery. I’m also a stickler for having a spare battery ready to go in the charger just in case; I hate waiting for batteries to charge.

The “Reel-Easy” bump-feed string head is actually easy to fill with cutting line and a satisfying step above older heads. The Ryobi 40 Volt Attachment Capable Cordless String Trimmer is compatible with their entire family to attachments including a pole saw, leaf blower, lawn edger, and hedge trimmer among others. It’s also compatible with other universal attachments made by other manufacturers. I’ve had great luck with Ryobi models (and I’m a bit of an organizational freak when it comes to tools), so I stick with them.

best, cordless, string, trimmers

All in all, this Ryobi cordless string trimmer will have you shaping up your yard in nothing flat so you can enjoy the rest of your weekend. Highly recommended.

Greenworks Pro 16-Inch 80V Cordless String Trimmer

Greenworks has done a great job of carving out a large niche for themselves in the electric power tool market. Their line of yard equipment is tough and powerful. This model, the Greenworks Pro 16-Inch 80V Cordless String Trimmer, offers up to 45 minutes of run time with a fully charged 2.0Ah battery. The motor is brushless so it’s more reliable and delivers the performance equivalent to a 32cc gas engine. Not too shabby. Unfortunately this trimmer doesn’t come packaged with the battery nor the charger however you can order them at the links provided if this is your first Greenworks tool.

The trimmer spool is self-winding with a nicely intuitive feed structure. You really shouldn’t have any issues reloading string into this trimmer. The 80V battery is heavy but the tool balance is like an average gas trimmer. The shaft handle may be adjusted to suit your particular working style. When operating, the trimmer runs at a moderate speed. Hit the speed switch and you immediately head to 80V territory for heavy-duty tasks.

The Greenworks Pro has a feature not found on many other (if any) trimmers: the ability to interface with attachments made by other companies such as Ryobi, Homelite, Poulson, and others. This means you could grab a pole saw from another manufacturer and use it with the trimmer with enough power and style to get the job done.

Sun Joe 24V SB10-LTE Cordless Electric Stringless Lawn Trimmer

When I’m putting these lists together, I always like to include one of the products from Sun Joe and the reasons are this: they definitely have a fan base and they’re just plain cheap, in price more so than quality. The Sun Joe 24V SB10-LTE Cordless Electric Stringless Lawn Trimmer does not include the required 24V battery nor the charger; make sure to pick one (and maybe a spare) up. This model weighs next to nothing and is a great little trimmer for a small to medium-sized yard. You’re going to get between 20 to 30 minutes of use on one charge depending on how you use it.

The Sun Joe features stringless trimming with a flexible, yellow, plastic, 10-inch blade that mows down thick grass like butter. The head rotates 180 degrees at the top where you control it to create an effective edging machine. There’s also a wire guard at the front of the trim head that protects plants from your wicked, whirling blade of death, provides a guide while edging, and that gives you a visual of where the blade is at.

Here’s my challenge: I really don’t know how much damage the one (come ON, Sun Joe; one?) blade can take. I whack weeds around all sorts of trees, brick, concrete, and what have you so I can only imagine it wouldn’t take an inordinate amount of time. That said, Sun Joe promotes that their blades are equal to over 200 feet of string and I really couldn’t find any reports of anyone that had problems with the blade. I think you ought to pick up some replacement blades just in case.

I like that Sun Joe doesn’t get full of themselves. They understand their core market: owners of small yards that need a light and half-way durable machine that doesn’t cost a fortune. You can’t argue with the online reviews from people who love this trimmer. The Sun Joe 24V SB10-LTE Cordless Electric Stringless Lawn Trummer costs next to nothing and does a reasonably good job at what it’s supposed to do.

Ryobi 18V One Plus Cordless Electric String Trimmer

The Ryobi One Plus 18V Cordless Electric String Trimmer is not a professional yard maintenance tool that will take out vast patches of tall, thick weeds for eight hours straight. If you need to trim a half-acre or more look elsewhere on our list and you’ll find a better machine for you. No, what the Ryobi One Plus 18V trimmer does is provide that perfect solution for small yards or limited trimming or edging needs.

It’s perfect for anyone who doesn’t want the hassle of a large power tool. In fact, one online review claimed that they could use this trimmer from their mobility scooter. That’s pretty cool. Before I read that, I hadn’t considered that sort of need. Consider me schooled.

This Ryobi One Plus 18V trimmer has 20% more power than the previous version yet only weighs five pounds. The cutting head features a single string but offers an auto-feed feature that gets away from the constant bumping of other models. It most likely has more power and durability than most people need for a typical lawn.

Be aware: this trimmer does not come with any batteries or a charger; take a look at this 3Ah battery two-pack and charger if you don’t already have 18V Ryobi batteries.

Greenworks 14-Inch 40V Cordless String Trimmer

A less expensive and powerful model than the Greenworks Pro 16-Inch Trimmer, the Greenworks 14-Inch 40V Cordless String Trimmer is more than enough machine for taking care of a medium-sized load of lawn maintenance. The brushless motor is built to last longer, run quieter, and deliver more torque while also providing a higher battery efficiency. The trimmer can be put together easily, right out of the box, and will start within seconds (using a freshly charged battery) with the power comparable to a gas-powered engine.

Unlike the 16-inch model, the 14-inch string trimmer comes with a 2Ah battery and charger at a reduced bundle price. The cutting head turns into an edger when needed and is attachment capable with the line of Greenworks products or competitor brands with a square drive shaft.

There are fewer ergonomic considerations with Greenworks than other brands. The support handle isn’t adjustable nor is the pole. At almost 13 pounds, it’s also heavier than other electric lawn trimmers. That aside, the power and efficiency the Greenworks 14-Inch 40V Cordless String Trimmer delivers makes up for its flaws and at a better price than its larger brother.

What Should I Consider When Buying A Cordless String Trimmer?

String trimmers are one of the most useful machines that a homeowner can have to maintain and detail their property. Whether used for wiping out vast swatches of scrubland or to put that finishing touch after cutting the grass, battery-powered weed eaters provide extension cord freedom and enough power to rival (or surpass) gas-powered models.

Before making a final decision on which string trimmer is best for your yard, take a look around. What kind of grass is your lawn primarily made up of? Thicker turf or brush will need more power than bluegrass.

The size of your yard will also make a difference. Make sure that whatever battery powers your machine offers enough runtime for what you need to do.

Obstacles also come in to play: fences, pots, foundations, trees, flower beds, and more. Does the trimmer you’re looking at feature a head that rotates for edging work? Some models offer replaceable heads so your trimmer can turn into an edger, leaf blower, hedge trimmer, or even a chainsaw.

Consider the vibration the unit makes along with the power-to-weight ratio. It’s no fun to get wiped out by your new electric weed eater by the time the job is done. Take a look at how replacement cutting string is loaded into the head and also how the string is replenished during work.

Nothing is worse than having to shut the trimmer down to fish out more cutting line because the auto-feed feature doesn’t work! Maybe you need a shoulder strap to help lug your trimmer around?

Finally, a note about safety: use caution and common sense when operating your string trimmer! Flip flops are just plain stupid when working with this tool. Your toes will hate you if that thin plastic line rotating at 6,500 RPM even thinks of grazing them.

Wear safety goggles. Summer is going to be over real quick if you take a rock to the face. Work gloves are a great idea, too.

And, yeah, I understand that it might be 90 degrees out but long pants are a must when operating landscaping power tools. It will take just one slip of the trimmer into a patch of gravel to give your shins a serious case of road rash. Be Smart!

A good weed eater comprises five key measurable factors: weight, motor strength, cutting width, price, and perceived value. We applied a universal standard to all 15 electric line trimmers to objectively give you the fifteen best.

Knowing the comparative value of an item requires applying an acceptable measurement standard to all the products. By limiting subjective factors, we can evaluate a product’s purpose fitness comparatively to its peers.

First, we used the 4- and 5-star review ratings on Amazon as the only subjective factor. Then we averaged cost per Watt and Cost per width-inch. Finally, we factored in the deviation of the evaluated unit’s weight from the average weight of all the products (5.842-pounds). Below are the results – SG Score is the Simplify Gardening score.

Ryobi 18 in. 10 Amp Electric Straight Shaft String Trimmer

Okay, so this is the crown-wearing, gold medalist of all the corded electric line trimmers. The reasons are not hard to find. Remember that we considered the price, calculating the cost per Watt and cost per mowing inch – and it still came out on top.

Unlike some of the other brands, Ryobi offers a single corded line trimmer – this model. BlackDecker has four versions covering a broad spectrum of motor strengths and width, but Ryobi decided to go big. The 10W motor is the biggest on any weed eater, and the 18-inch mowing width is also the widest. Though the bigger motor affects the unit’s weight (8-pounds), it still is not the heaviest (LawnMaster red Edition at 11.97-pounds).

If you need a job done that requires some punch, or if you have a more oversized yard, this is the best (if not only) option. It has the stamina and strength to deliver. Of all the Amazon reviewers, 88-percent gave the experience either a 4- or 5-star rating (out of 5-stars). One in twenty were not happy, mainly because the extra strength makes it a messy machine, creating dust. Wear safety equipment.

This powerful 10 Amp String Trimmer delivers an 18-inch cutting width, allowing you to cut more yards in less time. Not only is this trimmer attachment capable with ten different EXPAND-IT attachments, but it also comes with the REEL-EASY head that reloads in under 60 seconds. Best of all, this String Trimmer is covered under a 3 Year Limited Warranty.

Key Features

  • The 10 amp motor provides maximum performance when trimming through the toughest weeds, grass, and overgrowth
  • High mounted motor creates improved balance.
  • Ergonomic design with adjustable height and pivoting handle positions gives maximum comfort and control
  • 17-inch cut path gets the job done fast
  • Cord retention system prevents accidental cord disconnection
  • 3-Year Limited Warranty

BLACKDECKER String Trimmer with Auto Feed, Electric, 6.5-Amp, 14-Inch (BESTA510)

And the silver medal goes to the BLACKDECKER BESTA510. The brand has got it perfectly right, combining sturdy construction with a lightweight presentation – a whole 2.634-pounds lighter than the average and almost 9-pounds more lightweight than the heaviest.

As far as the subjective opinions of reviewers on Amazon, 88-percent gave the unit either a 4- or 5-star rating. The only electric weed eater that got a higher rating (90%) was also a BlackDecker.

The motor is an above-average 6.5 Amps, mounted off-center above the rotor. The position makes space for an added torque unit that acts as a power drive. The guard is robust and, instead of the usual bump-frame, the line trimmer has a wheel – allowing it to double up as an edger.

Adjusting the telescopic shaft is easy and will enable people of all sizes to change it with no fuss. The line feeder is a rare case of a functional auto-feeder. Many of the reviewed automated feed systems on other line trimmers don’t work, feeding more line than is needed and wasting cord.

BlackDecker has created a light yet chunky unit that adds torque to an already powerful motor. It is easy to operate, adjustable, and feels sturdy. It certainly deserves to be the runner-up.

Key Features

  • The 6.5 amp motor and POWERDRIVE Transmission provide maximum performance when trimming through the toughest weeds, grass, and overgrowth
  • The AUTOMATIC FEED SPOOL – AFS automatically feeds trimmer line when needed with no bumping required
  • 2-in-1 Trim or Edge with wheeled edge guide – rotate to convert from trimmer to wheeled edger
  • Lightweight, ergonomic design with adjustable height and pivoting handle positions gives maximum comfort and control
  • 14-inch cut path gets the job done fast
  • Cord retention system prevents accidental cord disconnection
  • 2-Year Limited Warranty

Earthwise ST00113 13-Inch 4-Amp Corded Electric Lawn Mower

And our bronze medalist is this weed eater from Earthwise. Earthwise won the best reel mower evaluation too. It would appear they make good products.

The Earthwise 13″ Corded String Trimmer is ready to tackle yard work with 8,200RPM of clean, quiet power. The adjustable telescopic handle and adjustable auxiliary handle allow you to work comfortably. Additional features include the flip-down edge guard to protect your flowers and borders while trimming and build-in cord retention to keep extension cords from coming unhooked. Powerful, lightweight, and easy to use. No Gas, No Oil, No emissions. Earthwise is the Clean Air Choice!

Your trimmer uses a.065-inch (1.65mm) diameter nylon line to quickly and easily cut grass and weeds. In time, the tip of the nylon line will become worn, and the auto-feed mechanism will automatically feed and trim a new line length. The cutting line will wear faster if the cutting is done along sidewalks or other abrasive surfaces or heavier weeds are being cut. The line will extend approximately ¼ in. with each stop and start of the switch trigger until the line reaches the length of the grass deflector blade. Do not bump the unit on the ground to feed line or for any other purpose.

  • Unplug the trimmer
  • Press the line-feeding button with one hand while pulling the line out with the other
  • Press the button repeatedly to release the line to the proper length. Each press of the button will release approximately 1/4 inch of line. (Note: Release only enough line to extend just beyond the blade. If too much line is released, the blade will be unable to cut it to the correct working length, and it may become tangled on the rotating shaft.)
  • Plug the trimmer in
  • Restart the trimmer and return to regular operation

Key Features

  • Comfort grip: rubber over-molded handle
  • Flip-down edge guard
  • 13″ cutting width
  • Automatic dual-line feed (.065)
  • Adjustable telescopic length

BLACKDECKER ST4500 3.5 amp 12-Inch Electric Trimmer/Edger

BlackDecker is more than a century in the making. Since its early days, when they released the first DIY handyman electric drill in 1947, they made machines that last. Since our earliest days as a small Baltimore machine shop, BLACKDECKER has remained steadfastly focused on customer needs. The ST4500 is a no-frill, budget machine with the highest score in its group.

Breaking from the orange and black theme, BlackDecker created the all-black model with a 12-inch cutting swath that runs at an impressive 10,000 rpm. Weighing in at 4-pounds, this is the lightest of all the contenders for the BEST electric weed eaters.

Key Features

  • 3.5 Amp motor is ideal for trimming weeds, grass, and overgrowth
  • 12-inch cut path with bump-feed spool gets the job done fast
  • Groom ‘N’ Edge converts from trimming to edging in seconds
  • Edge guide allows precise edging along sidewalks and driveways
  • Cord retention system prevents accidental cord disconnection

BLACKDECKER String Trimmer, Electric, 14-Inch GH3000

Like our silver medalist, this BlackDecker option also has a rear-mounted motor, but in addition, it has a curved shaft. The curved shart allows greater control of the cutting head, allowing you to position it more parallel to the mowed surface.

The higher Amperage from 6.5 to 7.5 pushes both the price and weight up, and I expect that the cost of curving the shaft also contributes to higher manufacturing and transport costs. Even still, BlackDecker has three of their electric line trimmers in the top 50%.

  • 2 nd place – BlackDecker 6.5A GH900 – Reviewers rating 90-percent 4 5-star reviews
  • 4 th place – BlackDecker 3.5A ST4500 – Reviewers rating 88-percent 4 5-star reviews

  • A wheeled edge guide offers comfort and ease of use while edging the lawn around sidewalks and driveways.
  • Lightweight, ergonomic design with adjustable height and pivoting handle give the user maximum comfort and control.
  • Single 0.80-inch line and 14-inch cut path deliver faster results, even when trimming tough weeds and grass.

Worx WG119 5.5 Amp 15″ Electric String Trimmer Edger

I must admit that I have a particular liking for WORX products. We have evaluated their battery-powered line trimmer and their powered wheelbarrows, and both were quality reasonably priced. The WORX Nitro WG186.9 40V Power Share PRO 15″ Cordless String Trimmer came in at the top of the mid-priced category and the Aerocart 8-in-1 cart, though not powered, really caught our eye as an ingenious design.

To extract a score of more than 80-percent on Amazon is not easy. Firstly, if your product is new, it doesn’t appear as a suggestion to searchers. Those first reviewers are more critical than later reviewers, which could hinder your product from getting any additional reviews. Either way, you have to have an exceptional offer to get four out of five people to constantly like your product.

Key Features

  • The WORX WG124 2-in1 Trimmer is designed for maximum performance. The 6 Amp electric grass trimmer incorporates a telescoping shaft and multi-position adjustable head for additional comfort.
  • Quickly rotate the handle and adjust the head for a fully functioning in-line wheeled edger, giving your lawn a professional look.
  • A foldable spacer guard prevents the cutting edge from damaging trees, furniture, walls, or delicate landscaping.
  • It also features a dual auto-feed trimmer line system, so you’ll never have to bump the trimmer to feed an additional line. The auto-feed ensures you have the perfect amount of line at all times.

FAQ

I’m really tall/short. Can I adapt the Worx 6 Amp 15″ String Trimmer / Edger to my height?

Yes! The 6 Amp 15″ String Trimmer / Edger is designed to be fully adjustable from the telescoping shaft, multi-position auxiliary handle to the pivoting trimmer head. Don’t contort yourself to fit your trimmer; let your Worx String Trimmer / Edger adapt to suit you.

Unscrew the black locking collar on the trimmer shaft. Adjust the length of the telescoping shaft to the most comfortable length and tighten it to secure.

How do I adjust the angle of the cutting head?

Your String Trimmer / Edger will click through the positions. Once you’ve found the perfect angle for you, you’re ready to get back at it!

How do I convert the GT from Trimmer to Edger?

Converting your trimmer from Trimmer to Edger is quick and easy.To change the tool for edging mode, adjust the angle of the cutting handle, so the cutting head is in line with the trimmer’s shaft. Grasp the handle and the part of the tool where the shaft meets the cutting head. Pull the handle away from the cutting head and twist clockwise. Release, and you’re ready to go!To return to trimmer mode, grasp the part of the tool where the shaft meets the cutting head and pull the handle away from the cutting head. Twist counter-clockwise. Release the handle. Adjust the angle of the cutting head to the most comfortable position for your height and the job at hand.

What kind of spools or cutting lines does this trimmer use? Can I get the Free Spools for Life offer?

The Worx 6 Amp 15″ String Trimmer / Edger uses the Worx WA0007 dual-feed spool, which is pre-wound with 16′ ft of our patented DoubleHelix DNA Line2. The Free Spools for Life will not fit this trimmer.

What kind of extension cord should I use?

The right extension cord will ensure you get the performance you expect and will extend the life of your blower. Look for an extension cord rated for Outdoor Use and make sure the cord gauge is appropriate for the length you’re using. The WG124 is a 6 Amp tool, so check for gauge and size on the grid in your manual. Your local hardware or garden supply store will be happy to help you select the right cord to meet your needs.

Toro 51480 Corded 14-Inch Electric Trimmer/Edger

Even though Toro is one of the biggest suppliers of turf management tools, if not the leader, they also make some tremendous domestic lawn care products. Americans are not unfamiliar with Toro as a lawnmower option. Still, they have a single electric line trimmer on offer – representing the TORO brand. In contrast, their website offers 11 battery-powered options – a clear indicator of where the market is moving towards.

Toro’s 5 Amp string trimmer and edger are robust and durable, with high-performing features that make yard care seem effortless. 14 in. wide dual line cutting width gets the job done quickly, and user-friendly features make the job much easier. With a simple 1-step push button, the operator can convert to edging in seconds. The wheel guides the edger for precision trimming.

Key Features

  • Powerful 5 amp motor easily cuts through thick grass and weeds
  • Extra-wide 14″ dual line cutting head gets the job done faster

  • The telescoping shaft and adjustable assist handle provide extended reach

Greenworks 13-Inch 4 Amp Electric Corded String Trimmer 21212

Here again, we have a brand that offers a single corded electric line trimmer and 41 battery-powered options. Increasingly we see fewer electrical and gas-powered options and an increase in lithium-ion-powered machines.

Greenworks also featured in our TOP 3 Reel Mowers article, although stronger contenders in that market took the top spots. The Greenworks scored high in the Amazon reviews. Still, they fared less well on our bang-for-buck algorithm.

85-percent of Amazon reviewers scored the Greenworks 21212 Electric Corded String Trimmer either 4-stars or 5-stars (out of a possible 5-stars). We awarded them only 41.71-percent – about half as good as the winner and twice as good as the lowest option.

It’s no wonder, as the company has always focused on cordless, something they’re good at making. Greenworks launched the first cordless string trimmer in 2007 already – first in the U.S.A. They also own 80% of that marker for batteries to power POE. Not bad.

With its quieter operation and more straightforward function, the 5 Amp Electric 14″ Straight Shaft String Trimmer offers a competitive alternative to gas-powered trimmers. Lightweight in construction, this trimmer is easy to maneuver and transport, meaning less fatigue and strain during long periods of operation. A 14″ cutting path handles most trimming jobs with ease and for edging along sidewalks and other pavements as well.

Key Features

  • Powerful 5 Amp motor to tackle the toughest weeds in the yard
  • 14″ cutting path to help you complete the job quicker
  • 0.065 dual-line auto-feed head makes advancing the cutting line simple and easy
  • Adjustable telescoping shaft to fit the user’s height
  • 3 Year Limited Tool Warranty

CRAFTSMAN String Trimmer, 14-Inch, 6.5-Amp, Push Button Feed System (CMESTE920)

Again, we have a machine that well with the Amazon reviewers and less well on our review. 85-percent of reviewers on Amazon gave the Craftsman CMESTE920 either a 4-star or 5-star rating. Very Good. But it fell short in our value-for-money algorithm.

The Craftsman brand is in the same stable as BlackDecker and Stanley tools. Similarities in design are visible, but the motor used on this machine is different—medium weight, mid-range motor, mid-range price – basically a middle-of-the-road offer to gardeners. Mid-everything, but topping the popularity charts.

6.5 Amp 14-in. Electric WEEDWACKER String Trimmer features a high-performance motor allowing the user to tackle tough overgrowth. The push-button feed system provides added control of the 0.065-in. line feed so you can get the job done quickly. This unit was built with the user in mind providing you with a built-in wheel guide for support while edging.

Key Features

  • 6.5 amp motor – high performance to tackle tough overgrowth
  • Ergonomic telescoping pole – featuring turn to edge capability
  • Push-button feed system – allowing you to control the line feed with the push of a button
  • Wheeled edger – turns from trimming to edging quickly with a wheeled edge guide for support while edging
  • 14inches Cutting swath with single 0.065inches Line
  • Includes 2 Replacement Spools

Sun Joe SB602E 11.5-Inch 4.5 Amp Electric SharperBlade 2-in-1 Stringless Lawn Trimmer, Green

Many of the solutions we use every day are because adventurous individuals try new things. Sun Joe’s SharperBlade option is a case in point. I can imagine the conversation – “Let’s put a plastic boomerang in place of the lines!”.

And that is how, maybe, both the Sun Joe and the Martha Steward line trimmers became the plastic blade trimmers. Interesting fact, the Martha Steward line trimmer is actually a Sun Joe product manufactured for the Martha Steward brand.

The SB602E trims a pristine 11.5-inch swath of grass with each pass thanks to SharperBlade, a proprietary, maintenance-free, self-sharpening trimmer blade system! Remove undesired plants and weeds and edge flower beds with the built-in flower guard while keeping your plants safe and secure.

LawnMaster Red Edition GT1644 Electric String Trimmer

And here we have our second beast of a machine – another 10 Amp motor. Surprisingly the LawnMaster fairs poorly compared to the other 10 Amp machine – our Gold Medalist, the Ryobi.

With one three out of four people liking a machine, those are not good odds to invest more than 70 – especially when for ten bucks more you can get the best there is. Still, LawnMaster is a good product, and the 5.5 Amp machine is ranked 11 th.

Lawnmaster’s GT1644 1201 electric string trimmer has a powerful 10 Amp motor with 6650rmp, making trimming through rough grass easier. The rear-mounted design provides a balance and comfort use for users.

The line trimmer is equipped with a front multi-positional auxiliary handle assembly to ease operation and prevent loss of control while aiding comfort during use. The innovative fixed-line head with an easy push-button allows the user to quickly change the.080″ trimmer line.

Martha Stewart MTS-SBLD1 11.5-Inch 4.5-Amp Electric SharperBlade Stringless Grass Trimmer/Edger

The Martha Steward brand continuously delivers hand-picked products, for which Martha puts her name and reputation on the line. The Martha Steward 4.5 Amp Electric SharperBlade, a Sun Joe product with its patented plastic blade, is loved by some and has not yet been adopted by others.

Priced to include brand value (for which the algorithm did not account), it comes in a bit expensive if you’re only looking for the functionality.

The professionals at Snow Joe have teamed up with Martha Stewart to provide you the best tools for your home, yard, and garden. She’s put together the perfect assortment to make your fall duties more enjoyable; everything from a small leaf blower to the ultimate pressure washer, from a powerful pole chainsaw to a stringless grass trimmer, Hori Hori knife, secateurs, or garden hose.

Best Lightweight String Trimmers: 2023 Buying Guide

Lightweight string trimmers are really good tools for those with smaller yards, back pain, or just like to move fast. Most weed eaters start at about 10-11 lbs but feel way heavier since they are over 5 feet long.

It doesn’t have to be this way. My parents (senior citizens) and my wife (woman) love using smaller weed eaters because they’re just easier. And they aren’t hardcore perfectionists like me who are obsessed with having heavy-duty tools.

But anyways – I have gotten a lot of questions lately over on our YouTube channel about what the best lightweight weed eaters are, mostly from older women. Let’s break it down today!

  • Greenworks 40V 12 inch Cordless String Trimmer
  • Ryobi ONE 18V 10 in. Cordless Battery String Trimmer and Edger
  • Black and Decker 14 inch String Trimmer
  • WORX WG162 20V Cordless String Trimmer
  • Sun Joe TRJ13STE Trimmer Joe 13” Weed Eater

Best Lightweight Electric Weed Eaters: Ranked

Many of these weed eaters I’ve gotten to use after borrowing from my neighbors, parents, or in-laws that told me how great they were. I’m taking into account my personal experience, my parents’ enthusiasm, and the specifications that make these the best.

Greenworks 40V 12 inch Cordless String Trimmer

We liked the Greenworks 40V 12 inch cordless string trimmer because it has much of the same performance as a big weed eater, but is noticeably lighter. Coming in at right at 9 lbs, this one is going to mostly feel like a bigger EGO string trimmer, but provide less fatigue (and less power).

We liked this tool because the Greenworks 40V battery series can be used with a ton of other Greenworks 40V products as well. There are a ton of those, including a big ole chainsaw, a bunch of their mowers, and more.

But for this string trimmer, I particularly loved the molded handle grip that takes even more force off of your fingertips. It also has a slightly bent D-loop handle that isn’t a fake plastic-y type of handle. Together, these make the 9 lbs feel even lighter.

While this isn’t the highest performing weed eater – a cutting swath of 12 inches – it is definitely a good cutting swath for smaller yards without crazy amounts of thick brush. It’s a great weed eater for a homeowner with a generally well-maintained yard. I also really liked the variable speed trigger on this, which lets you have complete control over how hard you are trimming.

Ryobi ONE 18V 10 in. Cordless Battery String Trimmer and Edger

So my neighbor has the Ryobi ONE 18V cordless string trimmer and I had spotted him using it one day when I went up and asked him about it. He recently had back surgery and was finally back to playing golf. He liked this tool because it was taking the weight off of his back and was extremely easy to use.

While it doesn’t look like much, this Ryobi string trimmer made it super easy for my elderly neighbor to get back to taking care of his yard, which I can definitely appreciate. At first glance, this weed eater doesn’t appear to meet any of the criteria I laid out below. It has a curved shaft (if you can call it that), it isn’t very adjustable, it’s got a tiny cutting swath – but man if it isn’t lightweight.

  • Automatic line advancement meaning you don’t have to flip it over and pull out more line when it inevitable breaks off
  • The 18V battery that can be used with a ton of other Ryobi 18V ONE tools (like this backpack sprayer of theirs)
  • A dang 3 year warranty
  • An insane price

Look – this electric string trimmer isn’t all about power – and that’s fine. But I challenge you to find a lightweight, easier to use weed eater on the block. You can find this one a number of places, like Home Depot (where my neighbor got it) for a really low price.

Black and Decker 14 inch String Trimmer

The Black and Decker 14 inch corded electric string trimmer was the first string trimmer I ever owned. I did a full write up about it last week because I found it in my garage and got nostalgic. It’s ranking high up here because it lasted me about six years and could keep on going if I hadn’t upgraded it.

This one is super convenient because it has a handle that rotates that lets you go from trimming to edging – really quickly. I like the fact that it has a cord because it makes it both extremely cheap and I never have to worry about charging batteries.

Another cool thing about this trimmer is that it can retract into itself and fold the handle up, making it fit into a space the size of a locker. It can easily hang on a nail in the garage. When using it, I can extend the trimmer, rotate the head, and balance it along a wheel to do some light edging work as well.

This one got me through many years in my first home on a budget. You can check the latest price on Amazon here, but it is dirt cheap.

WORX WG162 20V Cordless String Trimmer

Next up is the WORX WG162 20V string trimmer. This one is battery-powered and WITH the battery comes in at 5.5 lbs and without the battery weighs 4.5 lbs. That is incredibly lightweight.

  • 20V battery works with a ton of other Worx 20V tools
  • 12 inch cutting swath is slightly larger than a few of the competitors
  • Telescoping head lets you adjust the length of the trimmer or collapse it for easy storage
  • The head pivots for edging just like the Black and Decker above

One thing I don’t love about this trimmer, which is why it is ranking below the others, is that it only has a single speed. I like having as much control as possible (which my wife loves), so having a single speed really limits what I can do. In particular, it makes it hard for me to cut around delicate flowers without being absolutely surgical and/or wreckless.

Either way, this is still a great, lightweight string trimmer and marketed almost exclusively toward women (just my observation!). But given the lightweight feel and the ease of use – it is also a great lightweight string trimmer for seniors.

This one, like most Worx products, are found almost exclusively at Amazon – where the price is pretty ridiculous (low).

Sun Joe TRJ13STE Trimmer Joe 13” Weed Eater

One that definitely flies under the radar, the Sun Joe electric string trimmer and edger is nearly identical to the Worx one above. The main difference is that it has a slightly larger cutting swath at 13 inches and is a corded electric string trimmer instead of battery.

Weighing in at 5 lbs (and no additional battery to weigh it down further), this thing is on the list because it is featherlight. Oh – and it is also featherlight on the wallet. This thing is under 40. Yes, if you’re on a budget and looking for something light and easy – you aren’t going to do much better than this.

This is the ultimate string trimmer for people with tiny yards and aren’t snobby about their tools. Sun Joe is not big in the lawn care space (yet), so you aren’t going to be building out your full suite of lawn tools with them. We have the Sun Joe dethatcher and have used a few other Sun Joe tools and honestly – they aren’t bad.

So – what do you have to lose? 40 bucks? That’s like a dozen eggs these days.

Go grab it on Amazon right now before hyperinflation takes it to the price of a normal weed eater.

Why we created The Lawn Review

The reason we started this website in the first place was because we had so much trouble trying to find reasonable, understandable, honest reviews for lawn equipment. And it’s not cheap! After hours and hours of research, trying products and returning them, and messing up our yards – we started this site.

As people who had to learn the hard way, we want you to know exactly what you are signing up for before you purchase a piece of equipment. That’s why we are committed to providing honest, easy-to-understand reviews that mean something.

What to look for in a string trimmer

Cordless weed eaters come in all shapes and sizes. They aren’t highly complicated pieces of equipment, but they do have a few nuances. Here is how I see it:

Feel

Obviously this is subjective, but feel is everything to me. I have had weed eaters in the past where the handle is off to the side, making me torque my shoulders and back. With the ones on this list, feel is less important because they’re so dang light. It is hard to torque your back or shoulder when there isn’t a ton of weight working against you.

Motor

Brushless motors are the best type of motors for electric lawn tools. They also produce more torque and less heat. They’re harder to find in lower-end lawn tools like the ones on this list. But if you can get one – it is good as gold and will last a long time.

Power Source

Depending on your situation, you may need to consider the power source. If you have a large yard with a lot of acreage, you may need gas to cover the whole area, while smaller yards (an acre or less) can get away with a battery or corded tool. These ones are all either battery or corded electric. If you get corded, just make sure you have a nice extension cord.

Curved vs Straight shaft

I always, always, always prefer straight shafts. They are so much easier to use and control. Curved shafts are better for smaller areas that require “mowing”, whereas straight shafts are better for precision and clean lines.

Bottom Line: Lightweight weed eaters

Y’all the good thing about these lightweight weed eaters is that they all get the job done and are lightweight on the wallet as well. The toughest choice you’ll make from this list is whether or not you want a battery or corded electric string trimmer.

Either way, your back will thank you for the featherweight tool and your lawn will look as good as new.

gardening tool manufacturers are opting for battery power over fuel or electric, and today’s string trimmers are a case in point. We tested these eco-friendly yard maintenance devices to help consumers make the right purchase for their property.

We may earn revenue from the products available on this page and participate in affiliate programs.

Handy outdoor power tools make quick work of tackling overgrown weeds and grass, giving the yard a tidy look and trimming hedges and shrubs. We put battery-powered trimmers through their paces on several grass or weed types to see how well they ran and cut, ultimately arriving at this list of the best battery trimmers.

For ensuring a polished look to a lawn, the best string trimmer is a great investment. These yard-care tools spin a cutting head loaded with nylon string (instead of a fixed blade) to cleanly trim the grass at the edge of a lawn or mow down weedy areas. Though gas and electric models once dominated, new and improved battery-powered versions don’t require mixing fuel or storing gasoline like gas string trimmers do, nor are they limited by the length of an extension cord, like corded electric string trimmers are.

Some battery trimmers are better suited to different-size yards, users, and budgets. So we could help consumers make the right choice, we tested some of the most popular string trimmers to find out how they perform under real-world conditions. To qualify as a top pick, a string trimmer should be durable, powerful, and easy to operate. The string line should exit the reel easily with no need for the user to constantly remove the reel cover and untangle the line.

The following battery-powered string trimmers are at the top of their class. Anyone looking to invest in a trimmer is likely to find one here to fit their landscaping needs.

How We Tested the Best Battery Trimmers

To truly test these battery-powered string trimmers, we started by assembling the tools and charging the batteries. Most trimmers arrived with the batteries about 25 percent charged right out of the box, but a full charge allowed us to gauge runtime at full power. Although some of the trimmers offer lower power settings that could extend runtime, we found that the lower settings simply made them less capable when it came to coarse weeds, so we ran them at full power for testing.

We put each trimmer through its paces in a variety of real-world scenarios: “clean” lawn grass, weedy grass, and natural areas featuring coarse, weedy seedlings and vines. To earn a spot in our lineup, the lightweight 20-volt (V) trimmers had to deliver a clean, crisp cut in both clean and weedy grass sections. In addition to trimming the grass zones, we used the 36V, 56V, and 80V models to cut through woody, viny growth in natural areas. Along with cutting power, we tested for battery runtime, maneuverability, and operator comfort and determined the best battery trimmer by category.

Our Top Picks

These reviews describe the key features of each cordless string trimmer and how the models performed in our backyard tests.

STIHL FSA 60 R 36V Battery Trimmer

It makes sense that the STIHL FSA 60 R would be a top performer in this test group. It comes from a brand with a long history of industry-leading outdoor power equipment. This string trimmer measures just over 66 inches long, weighs less than 10 pounds with the battery installed, and works for about 25 minutes per charge. The 36V 3.9 amp hours (Ah) battery charges in a little more than 2 hours.

The tough polymer material used for the motor housing and debris shield help keep the weight down. A few other standout features include a variable-speed throttle trigger, trigger interlock, battery retainer latch, EasySpool cutting head, bump guard, and hang loop. The trigger interlock and battery retainer latch prevent accidental startup. The variable trigger and EasySpool head improve operating efficiency by saving battery life and minimizing the time it takes to reload, respectively. The bump guard protects sensitive surfaces during close trimming, and the hang loop offers a convenient way to store the tool when not in use.

This is a great all-around pick for quarter- to a half-acre yards. The relatively short runtime of the STIHL FSA 60 R belies a very capable trimmer. In our tests it easily and cleanly sliced through all kinds of grass and weeds, including tough tree saplings up to about ¼ inch thick. The shorter runtime actually mattered less because the trimmer cut so well, and we moved at a faster pace than with some of the other trimmers with longer runtimes.

The other thing we noted here was the amazing level of operating comfort. The trimmer was fairly lightweight to begin with, but the weight was so well balanced—with just enough weight forward of the front handle to keep the head near ground level—that using it required significantly less effort than what was required of some of the other trimmers that weighed about the same. Also, vibration was minimal, so after trimming we had plenty of energy to keep working.

  • Weighs less than 10 pounds but easily powers through tough weeds
  • 25-minute runtime per charge for about 5,000 linear feet of trimming
  • Excellent balance to keep the head at ground level
  • EasySpool head, bump guard, variable-speed throttle, and accidental start protection
  • Smallish 13.8-inch cutting swath is on the small side for open spaces
  • 2-hour recharge time for battery is longer than that of some competitors

Ego ST1511T Power 15-Inch Powerload String Trimmer

Ego Power has made a name for itself in the outdoor power-equipment category by building an affordable battery-powered tool line that competes favorably against old-fashioned 2-cycle gas-powered equipment. The ST1511T 15-inch string trimmer proved to be powerful, clean, and quiet in testing. The 56V 2.5Ah lithium-ion battery delivers up to 45 minutes of runtime, with a recharging time of just 50 minutes. The bump-feed trimmer head comes preloaded with 0.095-inch trimmer line for more cutting force and less noise. Taller users will appreciate the straight shaft design, and the unit weighs in at just over 10 pounds.

In our tests, the Ego trimmer showed ample power to cut through everything in its path, including overgrown, weedy grass; privet seedlings; and honeysuckle vines. Its well-balanced design, with the heavy battery in back offset by the long, straight shaft, made it comfortable to work with and more agile than others we tested. Our only caveat: For seasonal yard cleanup or maintaining larger landscapes, the 45-minute maximum runtime may not be quite enough.

  • Auto-loading trimmer head reduces downtime while working
  • Adjustable telescoping straight shaft provides a custom fit for different users
  • Excellent power and runtime value at a moderate price point
  • Heavier than some with less forward weight to keep head down
  • Battery is bulkier than others, making the tool tiring to use over an extended period

BlackDecker LST300 LBXR2020-OPE 20V String Trimmer

To give the yard a polished look without breaking the bank, consider the BlackDecker cordless string trimmer. It features a 12-inch cutting swath to cut down the corners and clean up the edges of small- to medium-size yards. An automatic feed spool means no more stopping to bump the tool when new string is needed. Two 20V lithium-ion batteries are included.

In our tests, this trimmer performed very well in weed-free grass and in weedy lawn areas. With a light weight of just 5.7 pounds, this trimmer is easy to handle without causing arm and shoulder fatigue. The short, straight shaft design is most comfortable for users under 5 feet 9 inches tall. We also liked that with a quick adjustment to the head, the trimmer becomes an edger to neaten up the grass along sidewalks and driveways. In all, we found this affordable tool a solid pick for small obstacle-free landscapes.

  • Pack includes 2 batteries for more runtime, less downtime
  • Automatic feed spool
  • Money- and space-saving design that both trims and edges
  • Battery recharges in just 45 minutes

Get the BlackDecker battery string trimmer at Amazon (with extra battery) or The Home Depot.

Makita XRU15PT1 36V LXT Brushless String Trimmer Kit

The Makita XRU15PT1 string trimmer is a premium option to keep the lawn and garden under control. It can handle large yards with enough power to tackle dense weed growth. This cordless string trimmer comes with four 18V 5.0Ah batteries so you’ll never run out of power. Shoppers can purchase this model as a kit that includes a dual battery charger and two sets of batteries, or as a “tool only” for those who already have items from the Makita 18V tool platform.

With a long, straight shaft and high-power cutting head, this 10.4-pound trimmer feels like a pro-quality tool. It was well balanced and articulate while trimming around shrubs and between obstacles. It had plenty of power to cut through tough vegetation. In our tests, it made nice clean cuts and crisp edges in the grassy areas and tore through weedy privet seedlings and honeysuckle vines without hesitation. It’s an excellent candidate to replace gas equipment for medium to large landscapes, though the price may be high for budget-minded shoppers.

  • Runtime is longer than charge time for ready-to-go fresh batteries
  • Includes a second set of batteries for extended work
  • Gas-like power and performance for tough trimming jobs
  • Expensive trimmer due to the high cost of batteries
  • Small debris guard allows some material close to operator
  • Stiff bump head required a hard strike to let out line

DeWALT DCST972X1 60V MAX 17-Inch String Trimmer Kit

When an established leader in pro-grade cordless hand tools enters the lawn-care category, shoppers will want to take note. The DeWALT 60V battery trimmer packs a heavy-duty brushless motor powered by a 60V 3Ah FlexVolt lithium battery that lets it tear through all kinds of tough weeds for at least 40 minutes per charge.

This attachment-capable trimmer comes equipped with a straight shaft and Rapid- loading adjustable spool. It uses.080-inch trimmer line to cut either a 15-inch or 17-inch swath. A safety switch in the grip prevents accidental starts. Users can select high or low power, depending on the project, and control the trimming RPM with a variable-speed trigger. The universal attachment feature lets owners replace the trimmer attachment with a variety of other tool heads, including an edger, hedge trimmer, pole saw, and more.

The DeWALT battery trimmer was one of the heaviest we tested, but also the most powerful. With the standard.080-inch trimmer line that came pre-spooled, this tool had no trouble cutting anything from grass to thin tree seedlings and even tough blackberry canes. In low-power mode it offered more cutting force than the high- power setting of most others we tested. In high range it beat all but the STIHL, which was about an even match in terms of pure power. To be honest, high power was too much for many of our applications, so we also tested thoroughly in low range. It ran about 40 minutes on high, and about 60 on low.

Other than the heavy weight, the only negative point we have to offer is the noise. The trimmer is loud to begin with, and when initially triggering or feathering the trigger it makes an even louder whine/whistle sound. Still, it’s a very impressive tool at a fair price for the power and runtime and a good choice for large properties or cleaning up overgrown areas.

  • Battery type: 60V 3Ah FlexVolt lithium ion
  • Runtime: 40 minutes
  • Weight: 12.95 pounds
  • Outstanding power for clearing overgrown weeds and brush
  • Works with.080-inch or.095-inch trimmer line for normal or heavy trimming
  • Excellent runtime of up to an hour for average grass trimming
  • Power head can run other landscaping tool attachments
  • Heavy weight of just under 13 pounds, but no shoulder strap
  • Longer battery charge time at 135 minutes
  • Noisy operation, especially when initially triggering

BlackDecker LSTE525 20V MAX String Trimmer/Edger

Weighing just 8.8 pounds, this string trimmer is easy to carry, maneuver, and control with an adjustable handle and a safety trigger switch to prevent accidental starts. The 12-inch trimming radius is suitable for keeping the lawn properly maintained without damaging fencing, decks, trees, or other common yard obstacles.

This cordless string trimmer operates with a 20V battery that can last for up to 20 minutes, and a spare battery is included. For edging, simply turn the head and use the built-in wheel to balance as the trimmer string handles the task.

When we used the tool to trim weedy lawn grass patches and edge the curb and driveway, it made nice clean cuts and tracked well to make good straight edges. The shaft and handle adjusted to comfortably fit our 6-foot user. The tool is amazingly lightweight for the amount of power it offers, but the weight is mostly balanced to the front of the handle, and having to manually counterbalance it while working fatigued our tester. Though not built for heavily weed-infested yards, it has ample power and runtime to clean up curb lines, driveway edges, and otherwise maintain a smaller landscape.

  • Very lightweight and easy to carry
  • Handle is customizable to fit the size of user
  • Trimmer doubles as an edger with a simple turn of the head
  • Battery provides limited runtime, although a spare is included
  • Not enough power to tackle coarse, woody weeds
  • Weighted toward the front, which may cause user fatigue

Echo DSRM-2100 eFORCE 56V 16-Inch Battery Trimmer

A wide cutting swath, extended runtime, and powerful trimming ability make the Echo DSRM-2100 eFORCE battery trimmer an excellent choice for large yards. The straight-shaft trimmer is powered by a brushless motor and 56V 2.5Ah lithium battery for up to 56 minutes of powerful performance that rivals traditional 2-cycle trimmers. It cuts a 16-inch-wide swath to get the job done efficiently.

This battery trimmer weighs in at a comfortable 9.75 pounds, making it a relatively lightweight choice at this level of capability. It features battery-saving low/high power settings for different cutting conditions, a variable-speed trigger, and a cushioned handle grip for comfort. The Speed-Feed cutting head comes preloaded with.095 trimmer line and reloads quickly without disassembly.

The Echo eForce battery trimmer is an excellent value for large-property maintenance. In our tests, the cutting power seemed to be slightly less than that of the DeWALT and STIHL trimmers, but it was still very capable. In high-power mode we trimmed for about 40 minutes. But the better-than-average power and wider swath meant that in 40 minutes with the Echo, we were able to complete work that other trimmers would need an hour to accomplish. The noise level was good, and reloading was fast and easy.

This trimmer could have scored higher with improved balance. Although it is a lightweight trimmer overall, most of the weight is in the working end. The heavy cutting head forces the operator to compensate by lifting upward on the front handle and pushing downward on the rear handle while working. We tested with the 2.5Ah battery that comes standard. Working with the available 5Ah battery (sold separately) would rebalance the trimmer to some degree while doubling runtime and increasing overall weight.

  • Excellent price for this combination of power and runtime
  • Wide cutting swath and power performance for large properties
  • Rapid charging system charges the battery in less than 40 minutes

Get the Echo battery trimmer at The Home Depot or Acme Tools.

Worx WG163 20V Power Share GT 3.0 String Trimmer

Owners of small yards may find this lightweight string trimmer an excellent option. It weighs just 5.5 pounds and easily converts from a trimmer to an edging tool; a built-in wheel helps balance the tool while edging. A push-button feed system gives the ability to extend the trimmer string without bumping the 12-inch trimmer head or manually pulling additional string from the trimmer. It comes with two 20V batteries and a charger, and the battery lasts for up to 20 minutes on a full charge.

This Worx string trimmer tackled our grassy areas with ease, both the weedy and weed-free zones, but it wasn’t as capable on rough areas. We were particularly impressed by the edger function, which we found comfortable and well balanced thanks to the 90-degree shaft-rotation capability. The adjustable trimmer head and upper handle let us customize the working angle, but the process of doing so proved clunky. We had to reach down and turn a rather stiff knob at the connection point between the shaft and cutting head to unlock and relock the angle for each adjustment.

  • Battery provides limited runtime, although a second battery is included
  • Head-tilt adjustment is somewhat awkward and clunky
  • Relatively long 60-minute charging time for 20 minutes of runtime

Husqvarna 320iL 40V Battery String Trimmer

One limiting factor of most string trimmers is the cutting head’s direction of rotation; it matters more than one might think. The direction of rotation determines where the clippings will go, and in some situations, how the user should grip the trimmer. The Husqvarna 320iL 40V battery trimmer offers a solution, thanks to its dual-direction cutting head. At the touch of a button, we could change from clockwise to counterclockwise rotation and back, without changing grip on the handles.

This straight-shaft trimmer is powered by an efficient brushless motor and 40V 4Ah battery that drives about 45 minutes of runtime per charge. It features a Rapid-load cutting head that comes prespooled with.080 trimmer line and cuts a 16-inch swath. Low-vibration technology improves operator comfort, and the machine weighs in at just over 10 pounds with the battery.

The Husqvarna 320iL ranked near the top of the test group in terms of user comfort and quiet operation, but its power was somewhat underwhelming after the big showing from the STIHL and DeWALT trimmers. We were super impressed with the dual-direction feature. It allowed us to use the trimmer right- or left-handed, and we could safely trim curb lines from either direction without standing in the street. On high-power mode the trimmer performed lawn-trimming duty superbly, but in heavy weeds and natural areas it could not keep up with the more powerful trimmers.

Anyone not interested in going off the beaten path might still do well to consider this trimmer. Its balance is impeccable, rivaling the STIHL in comfort even though it’s a fraction of a pound heavier. And for quiet operation, this one takes the gold medal. The only real question regarding comfort and control was, why so many buttons? Its four thumb-operated buttons control on/off, high/low power, clockwise rotation, and counterclockwise rotation.

  • Dual-direction trimmer head leaves clippings where desired
  • Excellent balance for comfortable extended use and less fatigue
  • Among the quietest of the trimmers we tested

Worx WG170 20V Power Share Revolution String Trimmer

While plenty of string trimmers also function as edgers, we found this model to have the best dual-function design. At the push of a button, the trimming head on the Worx WG170 Revolution trimmer converts to an edger that rolls easily along the edge of a sidewalk or driveway. The head tilts up to 90 degrees, so it is easy to reach weeds on slopes while standing comfortably.

The trimmer comes with two batteries plus a charger and three extra spools of trimmer line. The string trimmer also boasts a handy spacer guard that keeps it from bumping into plants, and the shaft adjusts to suit taller or shorter users. It cuts a 12-inch swath and operates on a 20V lithium-ion battery. We tested the tool with the 2Ah battery, but it also comes with a 4Ah battery at some retailers.

In our yard, this trimmer cut through and created a crisp edge on both weedless and weedy lawn areas. We really liked the easy adjustable feature on the trimmer head: A twist lock holds it in just the right position, up to 90 degrees, for a customized working angle for users of different heights. Also, the batteries are interchangeable with those of many other Worx 20V cordless tools.

  • Adjustable upper handle to accommodate users of different sizes
  • Trimmer head converts to an edger for use along sidewalks or driveways
  • Comes with 2 batteries to make up for shorter runtime
  • Requires a relatively long charging time
  • Trimmer feels underpowered for tackling coarse, heavy weeds
  • Only 20 minutes of runtime per charge

Greenworks Pro 80V 16-Inch Cordless String Trimmer

The Greenworks Pro 80V trimmer is a quality tool that adapts to a variety of other functions with attachments such as a brush cutter. (However, attachments are sold separately.) The 2Ah battery provides up to 45 minutes of runtime and recharges in just 30 minutes. The brushless electric motor is efficient and quiet, providing plenty of torque to cut through heavy weeds without the noise and smell of a gas-powered unit.

In our test areas, the Greenworks Pro trimmer was powerful enough to cut through the toughest weeds and vines with ease. The heavy battery weighs the machine down toward the rear, but the included adjustable shoulder strap makes operation more comfortable. The battery is compatible with other Greenworks 80V tools. Just don’t get too excited about the variable-speed trigger: Although it’s intended to allow a gradual increase from “off” to “high” speed, we found the range of movement between the two to be minuscule; in effect, the trimmer is either “off” or “on.”

  • Battery type: 80V 2Ah lithium ion
  • Runtime: 45 minutes
  • Weight: 10.6 pounds without battery
  • Trimmer has a quiet, efficient brushless motor
  • The recharging time is only 30 minutes; runtime is 45 minutes
  • Gas-like power and performance without the noise and smell
  • Slight lag time between triggering and full power
  • The trimmer’s adjustable speed feature is difficult to use
  • Weight is balanced toward the rear, but shoulder strap helps

What to Consider When Choosing a Battery Trimmer

When shopping for string trimmers, also known as weed eaters, keep in mind yard size, how often the tool will be used, and the height and strength of the primary user. The following key considerations will help in selection.

Trim Width

Trim width, also called swath width, indicates how wide a path the trimmer will cut through weeds in a single pass. Many models on the market today feature swath widths of 10 to 18 inches. The wider the width, the more power the trimmer must have, which often means the tool will be heavier because it will require a larger, more powerful battery.

Battery Type

Running a string trimmer requires a hefty dose of power. Though most of today’s trimmers run on rechargeable lithium-ion (Li-ion) batteries, a few accept nickel cadmium (NiCad) batteries. Li-ion batteries are more powerful, but NiCad batteries are less expensive (an average of 70 to 125 less). Li-ion batteries also are smaller, hold a charge longer, and provide full power throughout the discharge cycle.

NiCad batteries suffer from “memory effect,” meaning if the battery is used before it has fully charged—or if it’s recharged before its power depletes—it will “remember” the earlier charge level and won’t hold a longer charge in the future. If choosing a trimmer that has a NiCad battery, let it charge fully before use and drain completely before charging. For most users, a string trimmer with a Li-ion battery will be the best choice.

Voltage

Along with battery type, consider how much operating power the battery has, which is measured in volts. Today’s rechargeable string trimmer batteries average from 18 volts up to an average of 60 volts of power. powerful batteries at the high end often are intended for commercial use and can cost 200 or more per battery.

Some string trimmers in this category sell without a battery (or battery charger), which the user must purchase separately. This could be a cost-saving benefit for those who are adding to a same-brand, battery-compatible cordless tool collection, since the same battery will power multiple tools. However, it can be more convenient to purchase a kit with multiple batteries to have one on the charger while the other is in use.

Feed Type

The “feed” of a string trimmer indicates how the trimmer head releases additional trimmer line as it becomes frayed and broken during use. The standby is a bump feed where the user bumps the bottom of the trimmer (the area where the spool attaches) on the ground to release a few inches of fresh line.

Some newer models feature an auto-feed sensor that gauges the length of the strings and releases more when needed. Still others have a push button to release more line. Auto and button feeds eliminate the need to bump the spool, which can reduce the risk of damage if bumped too hard, but many commercial-type trimmers still use bump feed because it’s quick and easy.

Curved vs. Straight Shaft

Some string trimmers feature a straight shaft that runs from the handle to the cutting head, while other models feature a distinct curve in the lower shaft about two-thirds of the way down. Some users find curved-shaft trimmers to be easier to operate since the spool end already rests at a handy angle for weed whacking.

Straight-shaft trimmers often accommodate interchangeable tools, such as a tree trimmer head, which can be swapped out depending on the task at hand. In general, straight-shaft trimmers work better for users at least 6 feet tall, while shorter users will appreciate curved-shaft trimmers.

Noise

Battery-powered string trimmers have a distinct advantage over gas-powered trimmers when it comes to noise pollution. Gas-powered trimmers are moderately loud, emitting an average of 90 decibels (about as loud as a motorcycle passing by from 25 feet away). By contrast, a cordless string trimmer emits approximately 77 decibels, which is comparable to casual conversation.

FAQs

Those who are still unsure about how to use a battery string trimmer may find the following answers to common questions about these tools helpful.

Q. Can a string trimmer cut weeds?

A string trimmer is used to cut and control weed growth around the home and garden. However, light-duty trimmers may have issues with very dense weed growth.

Q. Can you use a string trimmer to cut grass?

A string trimmer can be used to cut grass, though you need to be careful not to cut the grass too short while trying to keep the trimmer balanced. It isn’t the easiest way to cut the grass, but it is possible.

Q. Can you edge with a string trimmer?

Yes, a string trimmer can be used for edging the garden, driveway, walkway, or sidewalk. If you have a large yard, it may be better to invest in a separate edging tool.

Q. How many volts should be in a trimmer?

String trimmer batteries average from 18 volts up to 80 volts. Typically, the higher the voltage, the longer the battery life.

Q. How do you edge a lawn with a string trimmer?

Hold the string trimmer perpendicular to the lawn to keep the cut even. Position the head about 4 inches off the soil so the string has space to rotate. The string should rotate and cut through the grass and dirt. As you move along the desired borders, keep the head balanced and even. Clean up the cut grass and dirt to finish the job.

Handy outdoor power tools make quick work of tackling overgrown weeds and grass, giving the yard a tidy look and trimming hedges and shrubs. We put battery-powered trimmers through their paces on several grass or weed types to see how well they ran and cut, ultimately arriving at this list of the best battery trimmers.

For ensuring a polished look to a lawn, the best string trimmer is a great investment. These yard-care tools spin a cutting head loaded with nylon string (instead of a fixed blade) to cleanly trim the grass at the edge of a lawn or mow down weedy areas. Though gas and electric models once dominated, new and improved battery-powered versions don’t require mixing fuel or storing gasoline like gas string trimmers do, nor are they limited by the length of an extension cord, like corded electric string trimmers are.

Some battery trimmers are better suited to different-size yards, users, and budgets. So we could help consumers make the right choice, we tested some of the most popular string trimmers to find out how they perform under real-world conditions. To qualify as a top pick, a string trimmer should be durable, powerful, and easy to operate. The string line should exit the reel easily with no need for the user to constantly remove the reel cover and untangle the line.

The following battery-powered string trimmers are at the top of their class. Anyone looking to invest in a trimmer is likely to find one here to fit their landscaping needs.

How We Tested the Best Battery Trimmers

To truly test these battery-powered string trimmers, we started by assembling the tools and charging the batteries. Most trimmers arrived with the batteries about 25 percent charged right out of the box, but a full charge allowed us to gauge runtime at full power. Although some of the trimmers offer lower power settings that could extend runtime, we found that the lower settings simply made them less capable when it came to coarse weeds, so we ran them at full power for testing.

We put each trimmer through its paces in a variety of real-world scenarios: “clean” lawn grass, weedy grass, and natural areas featuring coarse, weedy seedlings and vines. To earn a spot in our lineup, the lightweight 20-volt (V) trimmers had to deliver a clean, crisp cut in both clean and weedy grass sections. In addition to trimming the grass zones, we used the 36V, 56V, and 80V models to cut through woody, viny growth in natural areas. Along with cutting power, we tested for battery runtime, maneuverability, and operator comfort and determined the best battery trimmer by category.

Our Top Picks

These reviews describe the key features of each cordless string trimmer and how the models performed in our backyard tests.

STIHL FSA 60 R 36V Battery Trimmer

It makes sense that the STIHL FSA 60 R would be a top performer in this test group. It comes from a brand with a long history of industry-leading outdoor power equipment. This string trimmer measures just over 66 inches long, weighs less than 10 pounds with the battery installed, and works for about 25 minutes per charge. The 36V 3.9 amp hours (Ah) battery charges in a little more than 2 hours.

The tough polymer material used for the motor housing and debris shield help keep the weight down. A few other standout features include a variable-speed throttle trigger, trigger interlock, battery retainer latch, EasySpool cutting head, bump guard, and hang loop. The trigger interlock and battery retainer latch prevent accidental startup. The variable trigger and EasySpool head improve operating efficiency by saving battery life and minimizing the time it takes to reload, respectively. The bump guard protects sensitive surfaces during close trimming, and the hang loop offers a convenient way to store the tool when not in use.

This is a great all-around pick for quarter- to a half-acre yards. The relatively short runtime of the STIHL FSA 60 R belies a very capable trimmer. In our tests it easily and cleanly sliced through all kinds of grass and weeds, including tough tree saplings up to about ¼ inch thick. The shorter runtime actually mattered less because the trimmer cut so well, and we moved at a faster pace than with some of the other trimmers with longer runtimes.

The other thing we noted here was the amazing level of operating comfort. The trimmer was fairly lightweight to begin with, but the weight was so well balanced—with just enough weight forward of the front handle to keep the head near ground level—that using it required significantly less effort than what was required of some of the other trimmers that weighed about the same. Also, vibration was minimal, so after trimming we had plenty of energy to keep working.

  • Weighs less than 10 pounds but easily powers through tough weeds
  • 25-minute runtime per charge for about 5,000 linear feet of trimming
  • Excellent balance to keep the head at ground level
  • EasySpool head, bump guard, variable-speed throttle, and accidental start protection
  • Smallish 13.8-inch cutting swath is on the small side for open spaces
  • 2-hour recharge time for battery is longer than that of some competitors

Ego ST1511T Power 15-Inch Powerload String Trimmer

Ego Power has made a name for itself in the outdoor power-equipment category by building an affordable battery-powered tool line that competes favorably against old-fashioned 2-cycle gas-powered equipment. The ST1511T 15-inch string trimmer proved to be powerful, clean, and quiet in testing. The 56V 2.5Ah lithium-ion battery delivers up to 45 minutes of runtime, with a recharging time of just 50 minutes. The bump-feed trimmer head comes preloaded with 0.095-inch trimmer line for more cutting force and less noise. Taller users will appreciate the straight shaft design, and the unit weighs in at just over 10 pounds.

In our tests, the Ego trimmer showed ample power to cut through everything in its path, including overgrown, weedy grass; privet seedlings; and honeysuckle vines. Its well-balanced design, with the heavy battery in back offset by the long, straight shaft, made it comfortable to work with and more agile than others we tested. Our only caveat: For seasonal yard cleanup or maintaining larger landscapes, the 45-minute maximum runtime may not be quite enough.

  • Auto-loading trimmer head reduces downtime while working
  • Adjustable telescoping straight shaft provides a custom fit for different users
  • Excellent power and runtime value at a moderate price point
  • Heavier than some with less forward weight to keep head down
  • Battery is bulkier than others, making the tool tiring to use over an extended period

BlackDecker LST300 LBXR2020-OPE 20V String Trimmer

To give the yard a polished look without breaking the bank, consider the BlackDecker cordless string trimmer. It features a 12-inch cutting swath to cut down the corners and clean up the edges of small- to medium-size yards. An automatic feed spool means no more stopping to bump the tool when new string is needed. Two 20V lithium-ion batteries are included.

In our tests, this trimmer performed very well in weed-free grass and in weedy lawn areas. With a light weight of just 5.7 pounds, this trimmer is easy to handle without causing arm and shoulder fatigue. The short, straight shaft design is most comfortable for users under 5 feet 9 inches tall. We also liked that with a quick adjustment to the head, the trimmer becomes an edger to neaten up the grass along sidewalks and driveways. In all, we found this affordable tool a solid pick for small obstacle-free landscapes.

  • Pack includes 2 batteries for more runtime, less downtime
  • Automatic feed spool
  • Money- and space-saving design that both trims and edges
  • Battery recharges in just 45 minutes

Makita XRU15PT1 36V LXT Brushless String Trimmer Kit

The Makita XRU15PT1 string trimmer is a premium option to keep the lawn and garden under control. It can handle large yards with enough power to tackle dense weed growth. This cordless string trimmer comes with four 18V 5.0Ah batteries so you’ll never run out of power. Shoppers can purchase this model as a kit that includes a dual battery charger and two sets of batteries, or as a “tool only” for those who already have items from the Makita 18V tool platform.

With a long, straight shaft and high-power cutting head, this 10.4-pound trimmer feels like a pro-quality tool. It was well balanced and articulate while trimming around shrubs and between obstacles. It had plenty of power to cut through tough vegetation. In our tests, it made nice clean cuts and crisp edges in the grassy areas and tore through weedy privet seedlings and honeysuckle vines without hesitation. It’s an excellent candidate to replace gas equipment for medium to large landscapes, though the price may be high for budget-minded shoppers.

  • Runtime is longer than charge time for ready-to-go fresh batteries
  • Includes a second set of batteries for extended work
  • Gas-like power and performance for tough trimming jobs
  • Expensive trimmer due to the high cost of batteries
  • Small debris guard allows some material close to operator
  • Stiff bump head required a hard strike to let out line

DeWALT DCST972X1 60V MAX 17-Inch String Trimmer Kit

When an established leader in pro-grade cordless hand tools enters the lawn-care category, shoppers will want to take note. The DeWALT 60V battery trimmer packs a heavy-duty brushless motor powered by a 60V 3Ah FlexVolt lithium battery that lets it tear through all kinds of tough weeds for at least 40 minutes per charge.

This attachment-capable trimmer comes equipped with a straight shaft and Rapid- loading adjustable spool. It uses.080-inch trimmer line to cut either a 15-inch or 17-inch swath. A safety switch in the grip prevents accidental starts. Users can select high or low power, depending on the project, and control the trimming RPM with a variable-speed trigger. The universal attachment feature lets owners replace the trimmer attachment with a variety of other tool heads, including an edger, hedge trimmer, pole saw, and more.

The DeWALT battery trimmer was one of the heaviest we tested, but also the most powerful. With the standard.080-inch trimmer line that came pre-spooled, this tool had no trouble cutting anything from grass to thin tree seedlings and even tough blackberry canes. In low-power mode it offered more cutting force than the high- power setting of most others we tested. In high range it beat all but the STIHL, which was about an even match in terms of pure power. To be honest, high power was too much for many of our applications, so we also tested thoroughly in low range. It ran about 40 minutes on high, and about 60 on low.

Other than the heavy weight, the only negative point we have to offer is the noise. The trimmer is loud to begin with, and when initially triggering or feathering the trigger it makes an even louder whine/whistle sound. Still, it’s a very impressive tool at a fair price for the power and runtime and a good choice for large properties or cleaning up overgrown areas.

  • Battery type: 60V 3Ah FlexVolt lithium ion
  • Runtime: 40 minutes
  • Weight: 12.95 pounds
  • Outstanding power for clearing overgrown weeds and brush
  • Works with.080-inch or.095-inch trimmer line for normal or heavy trimming
  • Excellent runtime of up to an hour for average grass trimming
  • Power head can run other landscaping tool attachments
  • Heavy weight of just under 13 pounds, but no shoulder strap
  • Longer battery charge time at 135 minutes
  • Noisy operation, especially when initially triggering

BlackDecker LSTE525 20V MAX String Trimmer/Edger

Weighing just 8.8 pounds, this string trimmer is easy to carry, maneuver, and control with an adjustable handle and a safety trigger switch to prevent accidental starts. The 12-inch trimming radius is suitable for keeping the lawn properly maintained without damaging fencing, decks, trees, or other common yard obstacles.

This cordless string trimmer operates with a 20V battery that can last for up to 20 minutes, and a spare battery is included. For edging, simply turn the head and use the built-in wheel to balance as the trimmer string handles the task.

When we used the tool to trim weedy lawn grass patches and edge the curb and driveway, it made nice clean cuts and tracked well to make good straight edges. The shaft and handle adjusted to comfortably fit our 6-foot user. The tool is amazingly lightweight for the amount of power it offers, but the weight is mostly balanced to the front of the handle, and having to manually counterbalance it while working fatigued our tester. Though not built for heavily weed-infested yards, it has ample power and runtime to clean up curb lines, driveway edges, and otherwise maintain a smaller landscape.

  • Very lightweight and easy to carry
  • Handle is customizable to fit the size of user
  • Trimmer doubles as an edger with a simple turn of the head
  • Battery provides limited runtime, although a spare is included
  • Not enough power to tackle coarse, woody weeds
  • Weighted toward the front, which may cause user fatigue

Echo DSRM-2100 eFORCE 56V 16-Inch Battery Trimmer

A wide cutting swath, extended runtime, and powerful trimming ability make the Echo DSRM-2100 eFORCE battery trimmer an excellent choice for large yards. The straight-shaft trimmer is powered by a brushless motor and 56V 2.5Ah lithium battery for up to 56 minutes of powerful performance that rivals traditional 2-cycle trimmers. It cuts a 16-inch-wide swath to get the job done efficiently.

This battery trimmer weighs in at a comfortable 9.75 pounds, making it a relatively lightweight choice at this level of capability. It features battery-saving low/high power settings for different cutting conditions, a variable-speed trigger, and a cushioned handle grip for comfort. The Speed-Feed cutting head comes preloaded with.095 trimmer line and reloads quickly without disassembly.

The Echo eForce battery trimmer is an excellent value for large-property maintenance. In our tests, the cutting power seemed to be slightly less than that of the DeWALT and STIHL trimmers, but it was still very capable. In high-power mode we trimmed for about 40 minutes. But the better-than-average power and wider swath meant that in 40 minutes with the Echo, we were able to complete work that other trimmers would need an hour to accomplish. The noise level was good, and reloading was fast and easy.

This trimmer could have scored higher with improved balance. Although it is a lightweight trimmer overall, most of the weight is in the working end. The heavy cutting head forces the operator to compensate by lifting upward on the front handle and pushing downward on the rear handle while working. We tested with the 2.5Ah battery that comes standard. Working with the available 5Ah battery (sold separately) would rebalance the trimmer to some degree while doubling runtime and increasing overall weight.

  • Excellent price for this combination of power and runtime
  • Wide cutting swath and power performance for large properties
  • Rapid charging system charges the battery in less than 40 minutes

Worx WG163 20V Power Share GT 3.0 String Trimmer

Owners of small yards may find this lightweight string trimmer an excellent option. It weighs just 5.5 pounds and easily converts from a trimmer to an edging tool; a built-in wheel helps balance the tool while edging. A push-button feed system gives the ability to extend the trimmer string without bumping the 12-inch trimmer head or manually pulling additional string from the trimmer. It comes with two 20V batteries and a charger, and the battery lasts for up to 20 minutes on a full charge.

This Worx string trimmer tackled our grassy areas with ease, both the weedy and weed-free zones, but it wasn’t as capable on rough areas. We were particularly impressed by the edger function, which we found comfortable and well balanced thanks to the 90-degree shaft-rotation capability. The adjustable trimmer head and upper handle let us customize the working angle, but the process of doing so proved clunky. We had to reach down and turn a rather stiff knob at the connection point between the shaft and cutting head to unlock and relock the angle for each adjustment.

  • Battery provides limited runtime, although a second battery is included
  • Head-tilt adjustment is somewhat awkward and clunky
  • Relatively long 60-minute charging time for 20 minutes of runtime

Husqvarna 320iL 40V Battery String Trimmer

One limiting factor of most string trimmers is the cutting head’s direction of rotation; it matters more than one might think. The direction of rotation determines where the clippings will go, and in some situations, how the user should grip the trimmer. The Husqvarna 320iL 40V battery trimmer offers a solution, thanks to its dual-direction cutting head. At the touch of a button, we could change from clockwise to counterclockwise rotation and back, without changing grip on the handles.

This straight-shaft trimmer is powered by an efficient brushless motor and 40V 4Ah battery that drives about 45 minutes of runtime per charge. It features a Rapid-load cutting head that comes prespooled with.080 trimmer line and cuts a 16-inch swath. Low-vibration technology improves operator comfort, and the machine weighs in at just over 10 pounds with the battery.

The Husqvarna 320iL ranked near the top of the test group in terms of user comfort and quiet operation, but its power was somewhat underwhelming after the big showing from the STIHL and DeWALT trimmers. We were super impressed with the dual-direction feature. It allowed us to use the trimmer right- or left-handed, and we could safely trim curb lines from either direction without standing in the street. On high-power mode the trimmer performed lawn-trimming duty superbly, but in heavy weeds and natural areas it could not keep up with the more powerful trimmers.

Anyone not interested in going off the beaten path might still do well to consider this trimmer. Its balance is impeccable, rivaling the STIHL in comfort even though it’s a fraction of a pound heavier. And for quiet operation, this one takes the gold medal. The only real question regarding comfort and control was, why so many buttons? Its four thumb-operated buttons control on/off, high/low power, clockwise rotation, and counterclockwise rotation.

  • Dual-direction trimmer head leaves clippings where desired
  • Excellent balance for comfortable extended use and less fatigue
  • Among the quietest of the trimmers we tested

Worx WG170 20V Power Share Revolution String Trimmer

While plenty of string trimmers also function as edgers, we found this model to have the best dual-function design. At the push of a button, the trimming head on the Worx WG170 Revolution trimmer converts to an edger that rolls easily along the edge of a sidewalk or driveway. The head tilts up to 90 degrees, so it is easy to reach weeds on slopes while standing comfortably.

The trimmer comes with two batteries plus a charger and three extra spools of trimmer line. The string trimmer also boasts a handy spacer guard that keeps it from bumping into plants, and the shaft adjusts to suit taller or shorter users. It cuts a 12-inch swath and operates on a 20V lithium-ion battery. We tested the tool with the 2Ah battery, but it also comes with a 4Ah battery at some retailers.

In our yard, this trimmer cut through and created a crisp edge on both weedless and weedy lawn areas. We really liked the easy adjustable feature on the trimmer head: A twist lock holds it in just the right position, up to 90 degrees, for a customized working angle for users of different heights. Also, the batteries are interchangeable with those of many other Worx 20V cordless tools.

  • Adjustable upper handle to accommodate users of different sizes
  • Trimmer head converts to an edger for use along sidewalks or driveways
  • Comes with 2 batteries to make up for shorter runtime
  • Requires a relatively long charging time
  • Trimmer feels underpowered for tackling coarse, heavy weeds
  • Only 20 minutes of runtime per charge

Greenworks Pro 80V 16-Inch Cordless String Trimmer

The Greenworks Pro 80V trimmer is a quality tool that adapts to a variety of other functions with attachments such as a brush cutter. (However, attachments are sold separately.) The 2Ah battery provides up to 45 minutes of runtime and recharges in just 30 minutes. The brushless electric motor is efficient and quiet, providing plenty of torque to cut through heavy weeds without the noise and smell of a gas-powered unit.

In our test areas, the Greenworks Pro trimmer was powerful enough to cut through the toughest weeds and vines with ease. The heavy battery weighs the machine down toward the rear, but the included adjustable shoulder strap makes operation more comfortable. The battery is compatible with other Greenworks 80V tools. Just don’t get too excited about the variable-speed trigger: Although it’s intended to allow a gradual increase from “off” to “high” speed, we found the range of movement between the two to be minuscule; in effect, the trimmer is either “off” or “on.”

  • Battery type: 80V 2Ah lithium ion
  • Runtime: 45 minutes
  • Weight: 10.6 pounds without battery
  • Trimmer has a quiet, efficient brushless motor
  • The recharging time is only 30 minutes; runtime is 45 minutes
  • Gas-like power and performance without the noise and smell
  • Slight lag time between triggering and full power
  • The trimmer’s adjustable speed feature is difficult to use
  • Weight is balanced toward the rear, but shoulder strap helps

What to Consider When Choosing a Battery Trimmer

When shopping for string trimmers, also known as weed eaters, keep in mind yard size, how often the tool will be used, and the height and strength of the primary user. The following key considerations will help in selection.

Trim Width

Trim width, also called swath width, indicates how wide a path the trimmer will cut through weeds in a single pass. Many models on the market today feature swath widths of 10 to 18 inches. The wider the width, the more power the trimmer must have, which often means the tool will be heavier because it will require a larger, more powerful battery.

Battery Type

Running a string trimmer requires a hefty dose of power. Though most of today’s trimmers run on rechargeable lithium-ion (Li-ion) batteries, a few accept nickel cadmium (NiCad) batteries. Li-ion batteries are more powerful, but NiCad batteries are less expensive (an average of 70 to 125 less). Li-ion batteries also are smaller, hold a charge longer, and provide full power throughout the discharge cycle.

NiCad batteries suffer from “memory effect,” meaning if the battery is used before it has fully charged—or if it’s recharged before its power depletes—it will “remember” the earlier charge level and won’t hold a longer charge in the future. If choosing a trimmer that has a NiCad battery, let it charge fully before use and drain completely before charging. For most users, a string trimmer with a Li-ion battery will be the best choice.

Voltage

Along with battery type, consider how much operating power the battery has, which is measured in volts. Today’s rechargeable string trimmer batteries average from 18 volts up to an average of 60 volts of power. powerful batteries at the high end often are intended for commercial use and can cost 200 or more per battery.

Some string trimmers in this category sell without a battery (or battery charger), which the user must purchase separately. This could be a cost-saving benefit for those who are adding to a same-brand, battery-compatible cordless tool collection, since the same battery will power multiple tools. However, it can be more convenient to purchase a kit with multiple batteries to have one on the charger while the other is in use.

Feed Type

The “feed” of a string trimmer indicates how the trimmer head releases additional trimmer line as it becomes frayed and broken during use. The standby is a bump feed where the user bumps the bottom of the trimmer (the area where the spool attaches) on the ground to release a few inches of fresh line.

Some newer models feature an auto-feed sensor that gauges the length of the strings and releases more when needed. Still others have a push button to release more line. Auto and button feeds eliminate the need to bump the spool, which can reduce the risk of damage if bumped too hard, but many commercial-type trimmers still use bump feed because it’s quick and easy.

Curved vs. Straight Shaft

Some string trimmers feature a straight shaft that runs from the handle to the cutting head, while other models feature a distinct curve in the lower shaft about two-thirds of the way down. Some users find curved-shaft trimmers to be easier to operate since the spool end already rests at a handy angle for weed whacking.

Straight-shaft trimmers often accommodate interchangeable tools, such as a tree trimmer head, which can be swapped out depending on the task at hand. In general, straight-shaft trimmers work better for users at least 6 feet tall, while shorter users will appreciate curved-shaft trimmers.

Noise

Battery-powered string trimmers have a distinct advantage over gas-powered trimmers when it comes to noise pollution. Gas-powered trimmers are moderately loud, emitting an average of 90 decibels (about as loud as a motorcycle passing by from 25 feet away). By contrast, a cordless string trimmer emits approximately 77 decibels, which is comparable to casual conversation.

FAQs

Those who are still unsure about how to use a battery string trimmer may find the following answers to common questions about these tools helpful.

Q. Can a string trimmer cut weeds?

A string trimmer is used to cut and control weed growth around the home and garden. However, light-duty trimmers may have issues with very dense weed growth.

Q. Can you use a string trimmer to cut grass?

A string trimmer can be used to cut grass, though you need to be careful not to cut the grass too short while trying to keep the trimmer balanced. It isn’t the easiest way to cut the grass, but it is possible.

Q. Can you edge with a string trimmer?

Yes, a string trimmer can be used for edging the garden, driveway, walkway, or sidewalk. If you have a large yard, it may be better to invest in a separate edging tool.

Q. How many volts should be in a trimmer?

String trimmer batteries average from 18 volts up to 80 volts. Typically, the higher the voltage, the longer the battery life.

Q. How do you edge a lawn with a string trimmer?

Hold the string trimmer perpendicular to the lawn to keep the cut even. Position the head about 4 inches off the soil so the string has space to rotate. The string should rotate and cut through the grass and dirt. As you move along the desired borders, keep the head balanced and even. Clean up the cut grass and dirt to finish the job.
