Greenworks Cordless String Trimmer Features and Specifications
Like most cordless tools, Greenworks 12-Inch 40V Cordless String Trimmer can be purchased as 'bare tool' or as trimmer+battery+charger.
Generally, 2 Ah 40V G-MAX lithium ion battery and charger are recommended for this cordless trimmer.
With 2 Ah battery, trimmer weighs only 7.87 pounds (~3.57 kg) and can operate up to 30 minutes on a single battery (2.0 Ah) charge.
If the grass is higher and thicker, and the trigger must be fully squeezed more often, operating time is shorter - unit doesn't feature brushless motor, but it is strong for 12" trimmer and rather efficient. Of course, brushless motors are even more efficient, but such motors also increase the price of such tools.
Note: Greenworks manufactures broad range of various tools that is powered with G-MAX 40V batteries and if you already own such battery or batteries, purchasing other tools as 'bare tools' can be rather cheap and cost effective. Also, Greenworks 12-Inch 40V Cordless String Trimmer is rather simple to use and maintain trimmer, but just in case, prior assembling the unit, be sure to thoroughly read the manual.
Standard battery charger can fully recharge the battery in ~1 hour, allowing the user almost constant operation using 2x2Ah batteries.
G-MAX 40V lithium ion batteries come in various sizes/capacities, and the larger the battery, the longer operating time on a single battery charge.
G-MAX 40V lithium ion batteries feature battery charge indicator in the form of 4 lights:
- 4 green lights: battery fully charged,
- 3 green lights: battery is at 75% capacity,
- 2 green lights: battery is at 50% capacity,
- 1 green light: battery is at 25% capacity,
- lights are out when the battery capacity indicator button is pressed: battery charge is at 10% or less and should be recharged.
Trimmer head is fixed and can't be rotated in different positions - edging could be little bit problematic, but this is lightweight trimmer and it is up to the user to rotate the whole tool for such tasks.
