Cordless String Trimmers: Are They Right for Your Yard?

Cordless electric string trimmers are lightweight, quiet, and easy to handle—but they're not for every job. Their lower power suits small yards and light trimming near the house. For thick brush, long fences, or large areas, gas or commercial units are essential. Using an underpowered trimmer on heavy work burns out the motor fast.

Key Considerations

Battery life: Most run 20–30 minutes per charge; some take 7–8 hours to recharge. Detachable batteries allow swapping for extended sessions.

Edging drains power: Built-in edger attachments are convenient but consume battery rapidly. Plan edging separately or buy a spare battery.

Top pick: Among major brands (Black & Decker, Worx, Greenworks), Greenworks consistently earns best reviews for battery longevity and sustained performance across charges.

Match the tool to the task. Cordless trimmers excel at quick, clean detail work—not heavy clearing.
