Best Cordless String Trimmers Compared: 10 Flagship Picks for 2026

Introduction

We put ten flagship battery-powered string trimmers from EGO, Ryobi, Greenworks, Husqvarna, Milwaukee, DeWalt, Echo, Toro, Skil and Hart side by side. Cutting power, cutting swath, runtime, weight and line loading all factored into how they ranked. Here is how each one performs and who it suits best.

How We Evaluate a String Trimmer

Three factors drive cutting performance: line speed, line thickness and motor torque. Faster line tips cut grass more cleanly, and anything above 5,000 RPM is in good shape; the top models reach 6,500 RPM, which we consider gas-equivalent speed and a real advantage in thick grass or ditches.

Line mass matters too. Most cordless trimmers take 0.080-inch line at minimum, but 0.095-inch is our recommendation for all-around performance, and 0.105-inch line powers through overgrowth more effectively. Keep in mind that thicker line draws more power and reduces runtime.

Cutting swath determines how much area you clear per pass. Look for at least 15 inches for most yards, with 16 and 17-inch models making sense for larger properties. And resist the urge to remove the guard for a wider path; RPM drops and runtime suffers.

Weight, runtime and line loading round out the picture. A fully loaded trimmer under 10 pounds is a big win, brushless motors with 0.095-inch line and a higher-capacity battery help on large properties, and learning to trim at low speed in lighter grass stretches each battery further.

EGO Power Load with Line IQ

EGO started with surprisingly strong performance and eye-opening vibration control, and the technology has only improved since. Power Load makes line changes the easiest we have ever used: thread the line into the middle and press a button. It works best with smoother lines, so keep that in mind if you hit snags.

The latest addition, Line IQ, is an automatic line feeding system that maintains a 16-inch cutting swath without bumping the head. It simply works. This model sets a very high bar for any brand hoping to claim the title of best battery-powered string trimmer.

Beyond convenience, it packs plenty of power, has great balance, and the self-feeding 16-inch swath keeps you working without interruption. Of the ten trimmers here, this is the one that takes our top pick.

Ryobi 40V HP Brushless Whisper Series Carbon Fiber

Ryobi is quickly becoming a force in the landscaping industry, and its combination of advanced battery and brushless motor technology lets this model run up to 0.105-inch line on a 17-inch cutting head. That is fantastic when you are reclaiming overgrown areas or simply have a lot of lawn to maintain.

As part of the Whisper series, it operates about 60 percent quieter than a comparable gas model thanks to deliberate work on sound pitch. We measured just 87 dBA at the operator’s ear in high speed, which is genuinely quiet for this class.

Greenworks 60V Bike Handle String Trimmer

Bike-handle trimmers are the way to go for large areas and long fence lines. The harness and shoulder strap shift weight off your arms and lower back while giving you a stable platform to maneuver the head, and the lightweight magnesium body and housing help too.

The four-speed Greenworks Pro 60V is our top choice among battery bike-handle options. Pull the handle-mounted trigger and its 6,500 RPM top speed with 16 inches of 0.095 line clears overgrowth in a hurry. A 4Ah battery powers the brushless motor, and we recommend a couple of batteries for larger properties or extended use beyond its rating for yards up to two-thirds of an acre.

Husqvarna 320iL

Husqvarna’s newly released 320iL is geared toward consumers but packs seriously pro features. Launched in 2023, it is the first battery-powered trimmer in Husqvarna’s line to carry the Weed Eater brand name, and with a stated top speed around 6,800 RPM it is a serious residential contender.

Combined with Husqvarna’s characteristic lightweight, low-vibration design, it is a strong candidate for the most comfortable string trimmer to use. The directional switch feature, normally seen on professional models for detangling grass around the shaft, is designed here to send grass clippings in the right direction when trimming along sidewalks and driveways.

Milwaukee M18 Brushless String Trimmer

Milwaukee’s M18 brushless string trimmer has been out since early 2020 and sits alongside the M18 Fuel Quick-Lock attachment system as the brand’s two outdoor options. This dedicated trimmer earns our recommendation. It is not part of the M18 Fuel system, but it is brushless and compatible with every M18 battery ever made.

This two-speed model features a 14 to 16-inch cutting swath that performed very confidently. What sends it over the top is the value: it comes in under 200 dollars as a kit with a 6Ah High Output battery that retails for 179 dollars on its own. If you are already a fan of Milwaukee tools, this is a great entry point into their outdoor line.

DeWalt DCST970

If you are on the DeWalt FlexVolt battery platform, it does not get much better than the DCST970. DeWalt gives you a 15-inch cutting swath on this 60V brushless trimmer with 5,800 RPM on the top end and 4,650 on low, and you can swap the pre-spooled 0.080 line for beefier 0.095.

It is a little heavier than some models: with the 3Ah 60V battery installed, total weight pushes over 11 pounds. The trigger grip section is also thicker than most, so it may not suit smaller hands.

Echo DSRM-2600

Echo’s flagship from its 56V eForce series, the DSRM-2600, has three speeds and a brushless motor topping out at 5,700 RPM. Add a 17-inch cutting swath and you get a fast, confident cordless grass-clearing machine.

Performance lands right in line with what we expect from a 25cc gas equivalent. Paired with a quality line such as Echo’s Black Diamond trimmer line, it powers through thick grass and stubborn overgrowth with plenty of confidence.

Toro 60V Flex Force 51835

Toro has been making top-tier gas-powered outdoor equipment for over 100 years but played some catch-up on the battery side. The 60V 51835 is the top performer of the Flex Force line, with a 16-inch cutting swath and a well-balanced design that makes good use of the bulky top-handled 2.5Ah battery pack.

The brushless motor provides enough runtime for small to medium yards. The variable speed trigger lets you feather the throttle, though the two-speed switch on the handle should stay high for most cutting. Because it is attachment capable, you can swap the trimmer head for an articulating hedge trimmer, pole saw, cultivator or edger, making it an excellent all-around tool that can serve as a full suite of homeowner equipment.

Skil 40V PowerCore LT4832C

If you need voltage-boost performance without spending 200 dollars or more, Skil has you covered. The LT4832C is a brushless battery trimmer that fills the need for a capable weed eater without going overboard on weight or price.

Its dual 0.080-inch line spins between 4,800 and 5,800 RPM across two speeds with a variable speed trigger. Reloads are simple: feed up to 16 feet of line through the head, then use the Smart Load system’s flip-out lever to wind the string onto the spool. With more power than most entry-level 18V or 20V models, it is a good fit for budget-minded buyers and carries a five-year limited warranty.

Hart 40V Brushless Supercharged

Sold at your local Walmart, the Hart 40V brushless supercharged is another attachment-capable option using a universal connection. It runs 0.095-inch line with performance that tops what a 25cc gas model can deliver.

Thanks to its carbon fiber shaft, weight comes down a bit without sacrificing the strength you need for the job. For the price and availability, it is one of the most accessible flagship-class trimmers on this list.

Line Loading: The Detail That Changes Everything

Manual loading is largely a thing of the past, though some trimmers still use manual heads. Look for fast-loading systems like Speed Feed or rapid load, where you thread the line through the head to the middle, twist to load it, and get back to work.

The best solution on the market right now is EGO’s Power Load design, which takes the fast-load concept and adds automatic winding. It gives you the easiest, quickest line changes available, which is a bigger quality-of-life upgrade than most buyers expect.

Conclusion

EGO’s Power Load with Line IQ takes the crown as our best cordless string trimmer, pairing effortless line changes with strong power, great balance and a self-feeding 16-inch swath. But the right choice depends on your priorities: Ryobi and Greenworks for large properties, Milwaukee for value, DeWalt or Echo if you are already on their battery platforms, Toro for attachment versatility, and Skil or Hart for budget-friendly performance.
