Why on earth would you buy a compressor to pump up a bike tire or ball. A decent bicycle floor pump will do a bike tire in about 30 seconds, a ball in about a minute, is reliable, and costs a lot less than a compressor. I also keep a mini hand pump in my soccer bag for inflating balls. I know quite a few bike riders who carry a CO2 cartridge to save the weight of a pump. However, I think that's silly. The weight savings is minimal, and if you make a mistake you lose all of your CO2 and are stuck by the side of the road.
