I would like to purchase a portable air compressor. It will mainly be for "home use". I would prefer a "quiet" one on wheels or portable with wheels and not one to just lift from place to place.
Take a 12volt portable air compressor, give it a badass inflation time, build it into a military grade powder ammo can and you have... Air Armor. Specialopstools gets that tires are not a "one size fits all" situation and neither are air compressors.
