The Best String Trimmers (2026)
Battery trimmers rated on swath, line system, and real runtime.
Gas string trimmers dominated yards for decades, but battery trimmers now handle most residential work. The best cordless models cut a 13 to 15 inch swath, feed line without stopping to bump the head, and run long enough on one battery to finish a quarter acre lot. The differences between them come down to line diameter, head design, and which battery platform you already own.
This guide compares four proven battery trimmers from EGO, DeWalt, Worx, and Black+Decker. Every pick is evaluated against manufacturer specifications, retailer documentation, and published expert reviews. ThePickLedger has not hands-on tested these products; the assessments synthesize documented specs and third-party findings so you can match the trimmer to your yard.
