The 13-inch cutting width handles medium yards efficiently and the auto-feed line system keeps things moving without manual adjustment. The 2.0Ah battery and charger are included and the 40V platform is compatible with other Greenworks 40V tools including their mowers and leaf blowers — useful if you’re building out a Greenworks battery ecosystem.

The 12-inch cutting width handles small to medium yards and the 2-speed control gives you flexibility between light trimming and tougher cuts. The automatic feed spool keeps line moving without bumping.

How to Choose a Cordless String Trimmer
Voltage is the most important spec — 20V handles small to medium yards, 40V handles medium to large yards, and 56V+ handles heavy overgrowth and large properties. Cut width determines how fast you cover ground — 12 to 13 inches is standard for residential use, 15 inches covers more per pass. Weight matters more than most buyers realize — if you have a lot of edging to do a lighter trimmer reduces fatigue significantly. Look for models that include battery and charger rather than tool-only versions unless you already own compatible batteries.
Cordless vs Gas String Trimmers
For residential use cordless wins in almost every category. Gas trimmers are louder, require fuel mixing, need annual maintenance, and are harder to start. Cordless models from established brands like EGO and Greenworks now match gas performance for typical homeowner use cases. The only scenario where gas still makes sense is if you have acres of heavy brush to clear on a regular basis — for a typical residential lawn cordless is the better choice.
Final Recommendation
For most homeowners the EGO Power+ ST1502SA is the best all-around cordless string trimmer — unmatched battery power, easy line replacement, and a 15-inch cut width that handles anything a residential yard can throw at it. On a budget the CRAFTSMAN CMCST900D1 gets the job done from a trusted brand. If weight is your priority the WORX WG163 at 5.5 pounds is the easiest to handle.
