The ALSO GO 21V Weed Wacker is a lightweight cordless string trimmer kit with two 4.0Ah batteries and a fast charger, delivering 60–80 minutes of runtime and a 12-inch cutting swath for efficient yard edge trimming.

Designed for homeowners who want cordless convenience without sacrificing performance, this 21V electric string trimmer balances runtime, motor speed and ease of use. Its 9500 RPM high-torque motor and automatic line feed make quick work of grass and overgrowth along fences, sidewalks and garden beds. The pack includes two long-life lithium batteries and a charger so you can maintain momentum on medium-sized lawns.

How long will the batteries last during typical yard work?

With two 4.0Ah lithium batteries included, you can expect continuous operation between 60 and 80 minutes depending on load and grass density. Running on lower-thrust trimming tasks yields the higher end of that range, while dense or tall weeds will shorten runtime.

• Includes 2× 4.0Ah lithium batteries for extended sessions
• 60–80 minutes typical runtime per full charge set
• Fast charger included to minimize downtime

What cutting performance does this cordless trimmer deliver?

The trimmer’s high-torque motor reaches up to 9500 RPM to provide steady cutting power for routine lawn maintenance. A 12-inch cutting swath coupled with automatic line feed reduces passes and speeds up edge work around obstacles and borders.

• High-speed 9500 RPM motor for consistent cutting
• 12" cutting swath for fewer passes and faster results
• Auto line feed system for continuous trimming without manual adjustments

Is the tool easy to handle and suitable for everyday users?

At approximately 5.95 lbs the trimmer is built for low fatigue and simple operation, making it accessible to a variety of users including seniors and people who prefer lightweight tools. Controls are straightforward so you can start trimming quickly without a steep learning curve.

What accessories and consumables come with the kit, and what should I expect to replace?
