Top Pick
GreenWorks 80V 16-inch String Trimmer

Lightest bare-tool weight at 8.2 lbs — easiest to maneuver

Runner Up
No image

The Greenworks Pro 80V 16" Brushless Trimmer delivers exceptional gas-like cutting power and 45–90 min runtime, making it one of the best electric options for thick brush — but most battery-included kits exceed the $200 budget ceiling and the 9–12 lb weight can cause fatigue.

Alternate Angle
No image

The widest cutting swath in the group paired with genuine gas-equivalent power and the longest warranty makes this the most complete cordless trimmer for tackling thick residential brush.

Worth a look
Echo eFORCE 56V String Trimmer Kit DSRM-2100C1

The Echo eFORCE DSRM-2100 is a professional-grade 56V brushless trimmer with excellent 56-minute runtime and solid thick-brush cutting power, but it slightly exceeds the $200 budget ceiling at most retailers (~$226+) and has a forward-heavy balance that some users find fatiguing.

How we picked the best

Buy for cutting power for thick brush, not the spec sheet

The strongest options here separated themselves by consistently delivering on cutting power for thick brush and battery life and runtime. That matters more than chasing the longest feature list if the day-to-day experience is weaker.

Use the runner-up as a tradeoff check

Greenworks Pro 80V 16" Brushless String Trimmer is the best pressure-test for the winner because it shows what you gain and lose when you optimize a different dimension. If you are tempted by it, make sure that trade is actually tied to your primary use case.

Pressure-test the cutting power claims

Before you buy, look for evidence that directly addresses cutting power rather than relying on brand reputation alone. The right product here is the one that still looks strong after you account for the downside that matters most to you.

Not worth it

Ryobi 40V 15 in. Expand-It Cordless Battery Attachment Capable String Trimmer with 4.0

The Ryobi 40V Expand-It delivers gas-comparable power for homeowners at $159, with a versatile attachment system and the easiest line-reload head reviewers have tested — solid for thick residential grass and moderate brush, but not for commercial or all-day heavy use.

  • Not commercial-grade; lacks power for all-day heavy brush clearing
  • Attachment locking mechanism reported as slightly fiddly
  • 0.080 in. line is not the heaviest gauge for truly dense brush
  • Curved shaft limits reach vs. straight-shaft models
