Best Battery-Powered Weed Eater for Homeowners

EGO PowerLoad String Trimmer with Line IQ ST1623T

EGO Powerload String Trimmer Line IQ

Even before becoming a household name, EGO launch out the gate with a fairly capable weed eater. Since then, the company improved power, capability, and vibration control. It now makes what we consider the best battery-powered homeowner weedeater in the industry.

With PowerLoad automatic line loading, EGO makes the easiest-to-load weed eaters we’ve ever used. For 2022, we felt their PowerLoad technology and carbon fiber shaft simply dominated the battery-powered string trimmer category for homeowners.

Price: Price: $299 with 4.0Ah battery and charger

Best Battery-Powered Weedeater for Power

Ryobi 40V HP Brushless Whisper Series Carbon Fiber String Trimmer RY402110VNM

Ryobi 40V HP Brushless battery-powered weed eater

Believe it or not, Ryobi has unleashed some incredibly powerful and feature-rich OPE products in the past couple of years. Their 40V HP brushless tools have redefined what we thought possible at these price points. Their latest flagship Whisper Series string trimmer produces truly impressive cutting speed and power.

Ryobi combined advanced battery and brushless motor technology to spin 0.105-inch line with a 17-inch cutting diameter. Plus, since this battery-powered weed eater falls under their Whisper Series, it operates with roughly 60% less noise than comparable gas models.

Price: $299 with 6.0Ah battery and rapid charger

Best Lightweight Battery-Powered Weed Eater

Makita ConnectX String Trimmer CRU03

Makita ConnectX String Trimmer

Makita claims 30cc of gas-compatible power in their ConnectX battery-powered weed eater. They dropped the tool weight under 10 pounds by shifting the battery to a harness you wear on your back. Because you can hold more juice, you get up to 1200Wh of capacity and commercial-level runtime. While Makita joins an existing group of companies sporting backpack batteries, ConnectX has a particularly value-based weight and performance combination we really like.

Price: $419 bare tool

Best Attachment-Capable Battery-Powered String Trimmer

Stihl Battery-Powered Kombi System KMA 135 R

Stihl 135 Series KombiMotor

When we reviewed and compared weed eater attachment systems, the Sithl 36V KombiSystem beat everyone in both performance and options. It felt like we had a gas-powered system in our hands. The KMA 135 R powerhead makes it even better.

Unfortunately, Stihl uses a proprietary attachment mechanism. However, they provide so many attachment options we don’t really mind. On top of all that, the extensive Stihl dealer and service network supports these tools long after the sale. That simply isn’t the case with most other manufacturers.

Price: $359.99 powerhead only

Best Budget Battery-Powered Weed Eater

SKIL 40V PWRCore Brushless Weed Eater LT4818-10

Skil PWRCore 40 battery-powered weed eater

With our best budget battery-powered weed eater recommendation we set a price limit: $160 for the entire kit—including battery and charger. The Skil 40V PWRCore Brushless Weed Eater (model LT4818-10) presents a powerful option that fits the bill.

This battery-powered weed eater really fills a need for a capable trimmer that doesn’t go overboard on weight or price. With more power than 18V/20V trimmers, it’s a good fit for budget-minded individuals.

Price: $159 with 2.5Ah battery and charger.

Best Battery-Powered Weedeater Overall

Husqvarna 520iLX Battery-Powered String Trimmer

Husqvarna 520ILX String Trimmer

When we’re talking about the best all-day, everyday professional tool for residential crews, we love the Husqvarna 520iLX string trimmer. It weighs almost nothing—an amazing tool. On top of that, you get really low vibration and well-rounded features mixed with top-notch cutting performance. While other pro brands match it in some areas, nobody has quite as good of an overall package as Husqvarna.

Price: $299.99 bare tool

Best Line for Battery-Powered Weed Eater Use

Echo Black Diamond 0.095-Inch Trimmer Line

Echo Black Diamond String Trimmer Line

We love Echo Black Diamond trimmer line . Denser than other brands and with sharper cutting edges, it excels when used with battery-powered weed eaters. We use Black Diamond 0.095-inch line specifically. It cuts like a thicker line without reducing trigger time.

The only potential issue we’ve seen ahs to do with the EGO PowerLoad system. That prefers smoother line and tends to snag on Black Diamond (loading and when feeding it out)—so we avoid it in that particular tool.

Price: $14.99 for a 1-pound package (253 ft.) or $60.99 for a 5-pound spool (1394 ft.)

More Battery-Powered Trimmer Options from Brands We Trust

Best DeWalt Battery-Powered String Trimmer: DCST972

We like the 17-inch cutting diameter of the 60V Max brushless battery-powered weed eater. This 2-speed trimmer features a universal connection system. You get a swift 5800 RPM on the top end and support for 0.95-inch line (it comes spooled with 0.080″).

Surprisingly, for DeWalt, it has a rather thick grip. It might bother those with smaller hands. Attachments can rotate in any of three positions—makin git easy to use the trimmer head for edging.

Price: $249 bare tool, $299 with 3.0Ah battery and charger

Best EGO Battery-Powered String Trimmer: ST1623T

There’s a reason we picked EGO’s Line IQ trimmer as our best overall for homeowners. It’s so easy to use with excellent performance and smooth operation, that it can make one of the worst tasks enjoyable.

Price: $299 with 4 Ah battery and charger

Best Greenworks Battery-Powered Weed Eater: ST60L254

Greenworks’ Pro 60V line has a few options and we like the ST60L04 as the best overall balance of performance and price for trimming. It’s a smooth-operating trimmer with an easy-loading Load N’ Go head that uses 0.095-inch line and runs for more than half an hour on its 2.5Ah battery.

Price: $179.99 with 2.5Ah battery and charger

Best Makita Battery-Powered Weed Trimmer: GRU01

We realize not everyone is in a place to jump onto Makita’s ConnectX system. If you want high performance with wider OPE and power tool compatibility, give the 40V max XGT GRU01 a look. It has three speeds and tops out with a blistering 6500 RPM. Plus, there’s an Automatic Torque Drive feature that auto-adjusts the speed to match what you’re cutting. Even better, this one is just 10.4 pounds with a 4.0Ah battery, giving it an excellent blend of performance and weight.

Price: $289 bare, $439 with 4.0Ah battery and rapid charger

Best Milwaukee Battery-Powered String Trimmer: 2825-21ST

Milwaukee’s M18 Fuel Quik-Lok attachment system still holds the top spot for the best Milwaukee string trimmer in our books. Its 2-speed brushless design does an excellent job on a wide range of grasses. Even though it doesn’t use a universal connection, the available attachments have done a fantastic job over several years of service with our crew.

Now that there’s a new commercial lawn mower, whispers of further Milwaukee OPE expansion are in the wind, so keep your eyes open in case something new in the string trimmer department shows up.

Price: $229 powerhead and string trimmer attachment, $299 string trimmer kit with 8.0Ah High Output battery and rapid charger

What We Look for in the Best Battery-Powered Weed Eater – A Buying Guide

Cutting Power

We consider 3 key metrics that contribute to cutting power in weed eaters: line speed, line thickness/mass, and the torque of the motor.

A faster line speed yields better and cleaner grass cutting. Most battery-powered string trimmers do well—at least in dry grass. You want at least 5000 RPM to ensure your line spins quickly enough to slice through thicker grasses. The top models on our list might spin at upwards of 6500 RPM. This really impacts cutting wet grass and thicker weeds.

Thicker trimming line also helps cut tougher grasses. Most battery-powered weed eaters we recommend handle 0.095-inch line. Some homeowner models use 0.080-inch. That works fine for dry grass, but tougher loads and coming into contact with cement boundaries and fencing can quickly run through line. A battery-powered weed eater that supports 0.105-inch tells you two things: 1) it has lots of power, and 2) you have a pro model in your hands.

Remember that thicker line or string means less runtime—all things being the same.

We also look for a motor that can maintain speed under load. Run a weed eater in wet grass and you can quickly hear the speed drop on lesser models. Models with brushless motors and higher torque keep the head spinning when it runs into those tough cutting situations.

Cutting Width

A wider cutting path means you get more work done in the same amount of time. It takes more battery power to run these wider cutting paths or swaths, however. Look for at least 15-inches of cutting diameter. If you end up with a 16- or 17-inch model, be sure you have the torque and battery size to handle those larger sizes.

Runtime

The average homeowner on a 1/4-acre lot only needs about 15 minutes of consistent trigger time to cover trimming. Most cordless string trimmers are able to hit that at high speed without too much trouble.

Professional lawn care crews and homeowners with larger properties or acreage need much more.

You may also want to maximize dual-speed models for their best effect. Learning how to trim at low speed for dry grasses gives you a lot more runtime that if you run the battery-powered weed eater at full-throttle the whole time.

Vibration

We highly value low-vibration string trimmers. We already have enough work to do managing the weight of such a long tool without vibration adding additional fatigue. Some of the latest models let almost no vibration up the handle to the user.

Weight and Balance

If you’re working all day on a lawn crew or even just putting the finishing touches on your own lawn, you want the lightest weight you can get without sacrificing the power you need. Bare weight isn’t everything—the battery can add a lot. If you can get a fully-loaded battery-powered string trimmer that meets your performance needs and comes in under 10 pounds, that’s a big win.

Balance is a consideration and the trimmers that have the best typically mount the motor on the trimmer head to counter the battery weight on the back. Many models also let you adjust the front handle to help dial in your fit.

If you’re after an attachment-capable model, you’re stuck with the motor in the back, and the balance shifts back. For those and trimmers that are simply heavier by nature, consider adding a shoulder strap to help you out.

Sound Level

Low noise is one of the major benefits of moving away from gas power. Cordless string trimmers we’ve tested range from decibels in the low 80s to the upper 90s (measured at our operator’s ear). Even at the top end, it’s an improvement over the majority of gas trimmers.

Your line selection plays a bigger part than it does on gas trimmers. Sometimes, switching the line you use can reduce the overall noise level or change the tone to a less irritating pitch.

Line Changes

When changing line, we don’t mind manual loading. We do, however, look for models with a fast-loading system (SpeedFeed, Rapid Load, etc). These loading methods let you feed line straight through the head and either turn the head to load it, or activate a power loader to pull in the string.

The best on the market right now is EGO’s PowerLoad design. It takes the fast-load concept and adds automatic winding and gives us the easiest, quickest line changes we’ve ever had.

Attachment Capability

Pro lawn crews typically have dedicated machines for string trimming, edging, and hedge trimming, but homeowners can save a lot of money by using interchangeable heads and tools that cover everything from blowing to brush cutting.

As we mentioned earlier, attachment systems require a top-mounted motor that affects the balance. It’s a trade-off you have to make for the convenience you gain.

One thing to keep an eye on is the attachment connection style. Models with a “universal” connection can use attachments from other brands, opening up far more choices. Recent multi-head systems including EGO, Milwaukee, and Stihl aren’t compatible with others, so you need to make sure they have everything you need before investing.

Why You Can Trust OPE Reviews

Ever check out a “review” site and you can’t tell if they actually tested the tools or if they’re just “recommending” the Amazon top sellers? That’s not us. We won’t recommend anything unless we’d actually use it ourselves and we don’t really care who the primary retailer is. It’s all about giving you a legitimate recommendation and our honest opinion of each product.

We’ve been in business since 2016 covering outdoor power equipment, writing reviews, and reporting on industry news in the landscaping, heavy equipment, and lawn care industries. Our Pro reviewers have lots of experience in these fields as well as the skills and experience to know whether these products can perform well on the job.

Each year, our team reviews and gets their hands on hundreds of additional landscaping tools and equipment at our shop and at media events and trade shows.

We work with dozens of professionals around the United States who review products for us on real job sites and consult with us on testing methods, categories, and weighting.

GREENWORKS OFFERS A 15 amp hour 80 volt back battery on their website.

Chris

I own the Echo model that was tested here and I have to agree with all the good and bad points that you made. The review was spot on. I wanted to add another few points as well about my experience. 1. Echo does not endorse it, but I use the PAS blower with this unit and it works perfect. 2. This trimmer has a known problem with full throttle bursts. It will cut power immediately if you don’t ease into the trigger on the first go, but once it happens you can just press the battery test button and… Read more »

Jon

So how much experience do you have mowing lawns and using a string trimmer Kenny? Are you a pro? what is your experience level with these tools? You seem like a newb……..

cliu122

I have the Ryobi 40v trimmer and it works great. I was considering Ego but couldn’t go with them because I need a trimmer that is attachment capable. Of all the trimmers on this list Ryobi seems to be one of the only ones that is attachment capable and is not very expensive.

Nathan Wiskamp

You would come out with this two weeks after I made my choice/purchase! It may be on the lower end of your list, but after two uses I’m still happy with my Ryobi 40-volt trimmer!

Alex von Reuter

I’m beyond thrilled with my Makita XRU07Z that I special order from Ohio Power Tool! The ingenuity of the two speed electronic transmission is one of the highlights. I will be though, visiting Ohio Power Tool soon, to purchase additional 5 Amp Batteries because I’ve used this Trimmer so much, I need some spare fuel.

Dave Wittmann

I run a small property maintenance company that does all facets of home maintenance, including landscape maintenance. None of these units have the power to do the job properly and none of them hold a charge long enough to complete the needed maintenance on a typical suburban property. In my opinion, the best value for a home owner is the Stihl KM55. It has multiple attachments, is reasonably priced, is powerful enough to get the job done and is Stihl quality.

Samuel Joseph Hale

This is the best trimmer I rigged up a black and decker trimmer to run off Milwaukee m18 red lithium batterys!

Joshua Burgess

Ryobi now has a 5.0 battery for $139 at home depot

Joshua Burgess

you guys did a great review as usual. not to be mean, but you should update the Ryobi battery as I just checked and they now have a 5.0 AH battery

Give away after the test?

John Miller

Great review guys. Lots of time and effort went into this one.

Greenworks

Thanks for including us in the review!! Sorry we forced you “to trim continuously for nearly an hour and a quarter” to run out that long battery life. #SorryButNotSorry

BobTChicken

Note that amp-hours are not directly comparable, because the tools work with different voltages. To get the energy capacity of a battery in watt-hours, multiply the amp-hours by the voltage. For example, this means that although DeWalt and Ego both have 7.5 amp-hour packs, the DeWalt (at 40 volts) has 300 watt-hours of energy, while the 56 volt Ego has significantly more at 420 watt-hours. As another example, the 4 amp hour GreenWorks pack at 80v actually has more energy on board (320wh) than the DeWalt.

enochlight

Not surprised EGO is killing it with there latest trimmer. Overall, they offer the best performing blower at their price point, and their mowers are top notch. Frankly, now that they’re releasing a snow blower this fall (and according to the teaser video footage they posted last week), EGO seems to be the best brand to go with for OPE needs, IMHO.

Great review. What would you recommend for the consumer that would be able to cut through blackberries (with a blade attachment if necessary)? The echo seems like a decent choice, there are blade attachments online, and seems like there is adequate power. Any other recommendations?

Thank you.

Scott Blanchard

Thanks Kenny! I’ve been searching hi and lo for a comprehensive review of these and finally found it. The only thing holding me back from EGO is lack of a brushcutter head, so I’m still teetering between Ego, Ryobi and Echo, but Echo’s issues with power dropouts and balance concern me. Also, the battery charge time vs runtime seems to be a real issue with Echo. I’m almost there with EGO, but if they came out with a bolt-on brushcutter head, I’d be all in with both feet. Have you heard anything? Also, based on the review that the “Oz… Read more »

Kenny, I’m intrigued by Milwaukee’s sneak peek of their upcoming “M18” li-ion string trimmer. The battery they have developed is only 18v but is 9 amp hour.

Can you comment on what could be happening here? It appears that they have been able to get power comparable to 50v trimmers out… Read more »

Anyone seen Ego’s “Bike Handlebar” version of the reviewed string trimmer? Currently only being sold outside the US. They also have a backpack battery system that’s not available to US consumers. The European version of the trimmer reviewed here has a quick release handle and comes with a shoulder strap. Not sure why Ego doesn’t make these products available to US consumers. http://www.egopowerplusuk.com/products/trimmers/56v-lithium-ion-cordless-15-bike-handle-string-trimmer-without-battery-and-charger.html/

dave divelbiss

Hey Kenny, Greenworks must have read this, as they now have a 9.8 lb version very similar to the one you tested. The Greenworks website does not show it, but Amazon is selling it. ST80L210 thanks for a great article, i think i’m going to get the Greenworks as amazon has it for 179 95 off the regular price

leo

I just spent a considerable amount of time trying to verify if the Ryobi model#40220 which you tested has a brushless motor. Two tects at Ryobi sat it is a brushless motor. The power head part #40002. I’m still not convinced .I bought this trimmer and I don’t want to use it if its not brushless.

Tom B

This article has been very helpful — thanks Kenny and Clint. I just spoke with Husqvarna to get more info on using the 536LiLX with grass and wood cutting blades. It looks like this unit is a very serious contender for anyone who wants a tool that will do heavy brush cutting as well as regular string trimming. You show the 536LiLX as not attachment ready, but if the user can swap the head with a wood cutting blade, then shouldn’t this unit be considered just as versatile as the attachment ready models you reviewed? Maybe even better considering you… Read more »

Tom B

This article has been extremely helpful — thanks. Since you showed the Husqvarna 536LiLX as not attachment ready, I called the company to confirm the unit can be used with grass and wood cutting blades. For anyone who wants a tool that will do heavy brush cutting as well as regular string trimming, it looks like the 536LiLX should be considered just as versatile as the “attachment ready” competitors. Or am I missing something — your input would be appreciated.

Rich

What about Greenwork’s other 80v trimmer, the no attachment model? I have both and much more enjoy the bottom motor as it’s quieter, much lighter, more efficient (did you feel how hot that gearbox gets on the top motor model? And it spins faster. I use it professionally and only complaint is the ergonomics when tilting the head for edging.

Joel Sauser

Did you also review the Ryobi trimmer that has the motor on bottom and doesn’t take attachments? Wonder how it compares

Timothy

I think you should maybe do a Best Battery Powered Chainsaw Roundup. I really enjoy reading your roundup so I can see comparison between the different products

Don

Great information. Unless I missed it something I would be interested in would be how long does it take to charge the batteries.

Dan2Jen

This was a GREAT review. I’m in the landscape industry managing some maintenance crews and am interested to see how these battery powered tools compare to gas models. I have some of the Milwaukee M18 OPE on pre-order and hoping to have it in my hands in another month. I’m anxious to see how it compares to gas (and these other battery options).

Joe

A big item missing from the comparison is which direction the trimmer head spins. Most professional trimmers spin counter clockwise. Last year I tried the Eco which spins clockwise and it was tough to use.

Chuck Stewart

Kenny: May be age of the articles, but seems to be a difference in the Kobalt reviews. Here you say the motor is at the top with the battery, but the Kobalt photo you show clearly shows the motor mid-shaft. Also your individual review of the Kobalt 80 volt (as covered in this article), describes the Kobalt 80 volt as a significant improvement over the previous 40 volt model because of the change in motor position to mid-shaft. Is there a new Kobalt 80 volt out in the last 8 months….what’s going on??

Chuck Stewart

I should have noted, your Kobalt comment on the motor being at the top was in the “Balance” section of the article.

Nic

Has anyone compared the EGO vs the new Milwaulkee?

Banana

Hi. Great review and I wish I’d seen it five years ago. Any chance of an updated version? Or at least thoughts on more modern models?
