A string trimmer decides how long the last 10 percent of yard work takes, and battery models have caught up with gas for most homes. The real differences are voltage, cutting width and whether the battery fits tools you already own. These 8 cordless string trimmers are real, currently-listed Amazon picks for 2026, from a featherweight 20V model to a heavy-duty 60V brush cutter, so you can match the tool to your yard and budget.

Best Overall

EGO’s 56V platform is the one most reviewers measure other trimmers against. The brushless motor and auto-wind head cut through thick weeds without bogging down, and the battery is shared across the EGO outdoor line. It is heavier and pricier than 20V options, so it suits larger yards.

EGO Power+ ST1511T 15-Inch String Trimmer — 56V brushless, 15-inch cutting swath, dual-line .095″ auto-wind head, about 9 lbs, 5-year tool warranty

Best Heavy-Duty

DeWalt’s 60V trimmer is built for dense brush and overgrown lots. The gear-driven design and variable-speed trigger give it more cutting force than most homeowner models. At around 12 lbs it is a tool for people with a lot to cut, not a light weekly touch-up.

DEWALT DCST970X1 60V MAX String Trimmer — 60V MAX brushless, 15-inch cutting swath, gear-drive design, variable-speed trigger, about 12 lbs, battery and charger included

Best for Ryobi Owners

The Ryobi 40V trimmer is the sensible choice if you already own batteries from the 40V line. It has an adjustable cutting width, a variable-speed trigger and works with Ryobi’s Expand-It attachments, so one power head can also handle other yard jobs.

Ryobi 40V RY40250 String Trimmer — 40V, 13 to 15-inch adjustable cutting width, variable-speed trigger, Expand-It attachment compatible, 4.0Ah battery kit

Best Mid-Price Pick

Greenworks 40V trimmers sit in the middle on price and weight, and the battery works across a large range of Greenworks tools. The shaft converts to a wheeled edger, which saves buying a separate edging tool for sidewalks and driveways.

Greenworks 40V 13-Inch String Trimmer — 40V, 13-inch cutting width, 2.0Ah battery with up to about an hour of runtime, converts to wheeled edger, telescopic shaft

Best Two-in-One

The Worx WG184 uses two 20V batteries to reach 40V-class power and converts from trimmer to edger without tools. Command Feed spool advance means no bumping the head on the ground to get more line, which is a small feature you notice every weekend.

Best Value Kit

Black+Decker’s LSTE525 ships with two batteries, which is rare at this price. It cuts a 12-inch swath, advances line automatically and folds into an edger. It is a light-duty trimmer for suburban lawns, not for thick brush.

BLACK+DECKER LSTE525 20V MAX String Trimmer — 20V MAX, 12-inch cutting swath, two batteries included, automatic line feed, converts to edger, about 6.3 lbs

Best Lightweight

At roughly five pounds, the Worx WG163 is easy to carry for small yards and for anyone who finds heavier trimmers tiring. It switches between trimming and edging in seconds, and the 20V battery fits other Worx tools. It will not handle tall, tough weeds.

WORX WG163 GT 3.0 20V String Trimmer — 20V, 12-inch cutting width, converts from trimmer to edger and mini-mower, Command Feed line advance, about 5.3 lbs

Best Budget Pick

Earthwise’s LST02010 is the cheapest way into cordless trimming here. It weighs about 4.4 lbs, has an auto-feed spool and a flip-down edging guard. The 10-inch swath and small battery mean short runtimes, so it fits townhouse and patio-size jobs.

Earthwise LST02010 20V 10-Inch String Trimmer — 20V, 10-inch cutting swath, 2.0Ah lithium-ion battery, auto-feed spool, flip-down edge guard, about 4.4 lbs

How to Choose

Match voltage to yard size. 20V trimmers handle small lawns and edging; 40V to 60V models are better for thick weeds and larger properties.
Check the platform. If you already own batteries from Ryobi, Greenworks, EGO or DeWalt, buying the tool-compatible trimmer saves real money.
Look at cutting width and line. Wider swaths and thicker line (.080″ and up) clear more ground per pass; thinner line suits light grass.
Consider weight and balance. A trimmer over 10 lbs gets tiring in longer sessions; shaft length and a second handle adjustment matter.
Pick the feed type. Auto-feed or Command Feed heads save the bump-and-pull routine; manual bump feed is simpler and cheap to repair.
