Our Top Picks

1. EGO POWER+ ST1524S 15” — Best Overall

Check price on Amazon

EGO dominates the battery outdoor power equipment space for good reason. The ST1524S has a 15-inch cutting swath, runs up to 45 minutes on the included 5.0Ah battery, and converts to an edger with a twist.

Key specs:

Why we like it: The powerhead/attachment system means you can add a blower, hedge trimmer, or pole saw later. One battery, multiple tools. That’s hard to beat.

Best for: Most homeowners wanting one trimmer that does it all.

2. Greenworks 40V 13” — Best Value

Check price on Amazon

For under $130 with battery and charger, the Greenworks 40V handles light-to-medium trimming with ease. It’s not as powerful as the EGO but it covers the basics.

Key specs:

Why we like it: Solid performance at a budget price. If you have a small-to-medium yard and just need basic trimming, this saves you $100+ over premium options.

Best for: Small to medium yards, budget-conscious buyers.

3. DEWALT 60V MAX 15” — Best for Big Yards

Check price on Amazon

DEWALT’s 60V platform is a powerhouse. The FLEXVOLT battery delivers gas-like power and 60+ minutes of runtime. If you have a big property with heavy weeds, this is the trimmer to get.

Key specs:

Why we like it: If you already own DEWALT power tools, the battery cross-compatibility is a huge plus. The 60V motor handles thick weeds that would bog down 20V-40V trimmers.

Best for: Large yards, heavy vegetation, DEWALT tool owners.

4. BLACK+DECKER 20V 12” — Best Lightweight/Budget

Check price on Amazon

At under $70 and just 5.3 lbs, this is the easiest trimmer to pick up and use. The 20V battery gives about 25 minutes of runtime — enough for a quick trim around a small yard.

Key specs:

Why we like it: Incredibly light and easy to handle. The auto-feed spool eliminates bump-feeding frustration. Perfect starter trimmer.

Best for: Small yards, light trimming, anyone who wants simple and lightweight.

5. Milwaukee M18 FUEL 16” — Best Pro-Grade

Check price on Amazon

Milwaukee’s M18 FUEL line targets professionals but the quality benefits homeowners too. The brushless motor is incredibly efficient, and the QUIK-LOK attachment system is the best in the industry.

Key specs:

Why we like it: Build quality is a step above consumer brands. The QUIK-LOK system accepts edger, blower, hedge trimmer, and pole saw attachments. If you already own M18 batteries, this is a no-brainer.

Best for: Milwaukee tool owners, quality-focused buyers.

How to String Trim Like a Pro

  1. Trim before you mow — Clippings get mulched by the mower
  2. Angle the head — 10-15° angle to the ground for a clean edge
  3. Trim left to right — Throws clippings into the lawn, not onto beds
  4. Don’t scalp — Keep the line above soil level to avoid killing grass
