I've seen the battery-powered portable compressors, but am not sure I'd use one much. I picked up a Milwaukee mid-torque M18 FUEL 1/2" impact wrench which works great, including junkyard runs, plus no hassle carrying an air tank, or running out of air. The high-torque M18 impact is needed to match the 1/2" air power though.DId you see they are now selling battery powered 1 horsepower compressors in the holiday stuff at Home depot and lowes?
