Detailed Review
This cordless 2-in-1 string trimmer and edger provides a quiet, easy-starting solution for yard maintenance without the mess or hassle of gas equipment. It runs on an included 20V MAX 2.0 Amp hour lithium ion battery pack, designed for homeowners who want clean trimming and clean lawn edges from a single handheld tool.
A standout feature is the 6200 RPM motor equipped with the POWERDRIVE Transmission, which directs power straight to the cutting string for efficient work. You will not have to stop and tap the head against the ground thanks to the Automatic Feed Spool (AFS), which advances line on its own whenever required. It transitions from a standard trimmer to a lawn edger in seconds, letting you manage fence lines and driveway borders in one continuous session.
User comfort is supported by a lightweight construction paired with adjustable handle positions and adjustable height settings. The tool clears a 12-inch cutting swath on each pass, and recharging is managed through an included wall-mountable base that saves floor space in a garage or shed.
As a cordless tool running on a single 2.0 Ah battery, continuous runtime is limited to what one charge delivers, meaning very extensive trimming jobs may require pausing to recharge. The 12-inch cutting path is also more compact than larger commercial equipment, making it better suited for routine property upkeep than clearing massive overgrown fields.
Verdict: This 2-in-1 cordless tool is an excellent match for homeowners looking for hassle-free, gas-free trimming and edging on standard-sized lawns. It delivers quiet operation, automatic line feeding, and a customizable fit backed by a 2-year limited warranty.
