Choosing a 20-Volt Cordless String Trimmer for Your Yard

For compact yards, a 20V trimmer can keep edging and routine grass work simple. Compare the included battery, head width and whether you need a dedicated trimmer or a multi-function tool.

A 20V cordless string trimmer is best judged by the job it needs to do: light edging, regular grass maintenance or more involved clearing. The WORX WG173 combines trimming, edging and mini-mowing in one tool; the DEWALT DCST925M1 is a simpler 13-inch trimmer kit with battery and charger included.

Common questions

Questions before you buy

Is 20V enough for a cordless string trimmer?

It can suit routine trimming and edging, especially in a smaller yard. For dense weeds or larger areas, compare wider cutting paths and higher-voltage platforms as well.

Does the DEWALT DCST925M1 include a battery and charger?

Yes. DEWALT lists a 20V MAX 4.0Ah battery and charger in the DCST925M1 kit contents.

What is the difference between WORX WG173 and a basic 20V trimmer?

WORX describes the WG173 as a three-function tool for trimming, edging and mini-mowing, with a 13-inch cutting width. Check whether the selected configuration includes a battery and charger.

Can 20V batteries be used in 40V tools?

Battery compatibility depends on the manufacturer’s platform design. WORX states its PowerShare system can combine batteries for its 40V tools; do not assume packs interchange across brands.
