I am looking at my large 220 volt air compressor at new shop and contemplating not hard wiring it in as I normally do. I have not used it in six plus years as a result of the evolution of battery tools. Like most I love being cordless. I am just going to put a plug on it and not tie up a 220 breaker. I plug it in if I need it, with the torque the new 1/2 impacts have it has negated the need for me of air. I have not purchased a air tool in a long time. But I love having it as a back up. I just don’t need air anymore for my work load at home, still use it at plant tho.only down side is the storage of the battery tools is clunky.
