Cordless 21V Trimmer with 850W Motor

This cordless grass trimmer uses a 21V battery system and an 850W pure copper motor that reaches 18000 rpm. It functions as a string trimmer, lawn edger and brush cutter in one tool. Two 2000mAh batteries are included, providing up to 100 minutes of runtime without load.

Suits Small to Medium Gardens.

Homeowners who want a lightweight, wire-free tool for lawn edges, flower beds and light brush will find the 6-pound weight and 3-in-1 blade set practical. Buyers who need more cutting width or longer continuous runtime for dense overgrowth should look at something else.

Runtime Decided by Two 2000mAh Batteries

The package supplies two 2000mAh batteries that deliver 40 to 60 minutes of actual cutting time per charge. Recharging takes roughly 60 to 100 minutes. This capacity determines whether the trimmer can finish your yard in one session or requires a pause to swap cells.

Questions about this item

How often will the 2000 mAh batteries need recharging during a full day of yard work?

Each 2000 mAh pack delivers 40 to 60 minutes of active cutting, so a full day usually requires swapping between the two included batteries and recharging the depleted one.

What limits continuous cutting time before the motor overheats?

The 850 W pure-copper motor is designed with an internal cooling fan to dissipate heat, but sustained heavy load at 18000 rpm will eventually trigger thermal protection, making battery runtime the practical limit.

How much noise and heat does the 850 W motor produce when running all day?

The streamlined motor housing reduces wind noise and the built-in fan manages heat, so the trimmer stays noticeably quieter and cooler than gas equivalents during extended sessions.
