I have a double tank compressor, sometimes called a contractor model. It's heavy, but not so heavy that I can't carry it around. Compact, so it has a small footprint sitting in the garage. It will run an impact wrench or framing nailer without issue. Runs off of 120V, though it's not happy unless you're on a 20A circuit. The only time you need a compressor with a large tank is to run tools for an extended period of time at a constant pressure, such as a paint sprayer or air grinder.
