Best Lightweight Battery Powered Weed Eaters for Easier Yard Work

For the lightest published figure in this group, RYOBI PCLST01K is listed at 4.28 lb. STIHL FSA 57 stays under 8 lb with its AK 10 battery, while EGO's carbon-fiber shaft and Sun Joe's adjustable pole offer other ergonomic advantages.

Quick answer

RYOBI 18V ONE+ PCLST01K is the clearest lightweight pick: the manufacturer lists 4.28 lb and an adjustable 8-to-10-inch swath. STIHL FSA 57 is under 8 lb with the AK 10 battery; Sun Joe 24V-ST14 and EGO POWER+ ST1521S are alternatives if an adjustable head or broad cut matters more than minimum weight.

Best for the lowest published tool weight

RYOBI 18V ONE+ PCLST01K

  • RYOBI lists the trimmer at 4.28 lb.
  • The cut swath adjusts from 8 to 10 inches, and the shaft twists to edge along walks.

Drawback: Its narrow cut and 0.065-inch line suit lighter trimming rather than thick, overgrown vegetation.

STIHL FSA 57

  • STIHL describes the FSA 57 as a lightweight trimmer for suburban yards.
  • The maker lists a weight below 8 lb with an AK 10 battery and an adjustable shaft.

Drawback: STIHL's published weight and runtime depend on the battery configuration; the AK 10 runtime is up to 25 minutes.

Best for a telescoping pole and multi-angle head

Sun Joe 24V-ST14

  • The official product listing describes a telescoping pole and rotating 180-degree head.
  • It weighs 5.6 lb with battery according to the product listing, and the cutting head adjusts through 0-to-45-degree positions.

Best for a carbon-fiber shaft and wide cutting path

EGO POWER+ ST1521S

  • EGO lists a durable carbon-fiber shaft and a 15-inch cutting swath.
  • Its POWERLOAD head winds line at the press of a button, reducing fiddly spool loading.

Drawback: EGO does not list a product weight on the cited page, so compare the fitted battery and balance in person if low weight is essential.

Common questions

Questions before you buy

What is the lightest battery powered weed eater in this comparison?

RYOBI lists the 18V ONE+ PCLST01K at 4.28 lb. Confirm whether a listing gives tool-only weight or a complete kit, since batteries change the weight carried during use.

Does a lightweight weed eater work for tall grass?

A lighter tool can be easier to handle, but its line, motor and cutting width determine the work it can handle. Check the manufacturer's intended use and avoid expecting a compact trimmer to clear brush.

Is the STIHL FSA 57 lightweight with its battery installed?

STIHL says the FSA 57 weighs less than 8 lb with an AK 10 battery. The same source lists up to 25 minutes runtime with that battery, subject to operating conditions.

What makes a battery powered weed eater feel lighter?

Total weight, battery placement, shaft length and handle adjustment all affect how a trimmer feels. Compare the tool with its battery installed and consider whether the shaft or auxiliary handle adjusts to your reach.
