Greenworks ST1606A 60V 16-Inch Cordless String Trimmer

Greenworks ST1606A is a 60V cordless string trimmer listed with a 16-inch cutting path and a battery-and-charger kit. The listing conflicts on battery capacity and runtime, so confirm the exact bundle before buying. Its adjustable shaft and quick-reload head may suit routine yard trimming, while the stated 50-minute battery life should not be treated as a guaranteed working duration.

What to know before buying

Listing details to confirm

Battery and package details are contradictory: the title says 4Ah, a feature bullet specifies 2.5Ah, and the description claims up to 40 minutes with 4Ah while the bullet claims up to 50 minutes with 2.5Ah. The title also says 3A charger, while the description gives charging times of 70 minutes or less and about 80 minutes. Dimensions are inconsistent, with one listing value of 174.5L x 30W centimetres and another of 174.5 x 30 x 12.7 cm; 8.3 kg. Confirm the selected listing's battery, charger, runtime and dimensions.

Who is it for?

A good fit for

Buyers seeking a cordless trimmer for lawn edges, grass and weeds who value a 16-inch cutting width.
Owners of Greenworks 60V tools considering another tool for that stated battery platform, after confirming battery compatibility.

Less suited to

Buyers who need a clearly confirmed battery capacity, runtime or exact dimensions before purchase.
Buyers looking for a gas-powered trimmer or a listing with an unambiguous battery-and-charger configuration.
