Stihl Battery-Powered Chain Saw
Green, low-noise, and lightweight aren't normally attributes we associate with chainsaws, but you'll find them all in the Stihl Battery-Powered Chain Saw ($350). This particular unit is powered by a 36-volt lithium-ion battery, eliminating the need for awkward and dangerous power cords, or smelly, emission-producing gas engines. In addition, it features a toolless quick chain adjuster, a foot-long guide bar, and offers up to 60 minutes of run time on the AP 160 battery or 35 on the AP 80, neither of which are included — nor is a charger, so expect to incur some extra cost should you decide to go cordless.
