Walmart sells 12 volt air pumps for $20 and up.A plug kit takes up no room, and I have one in my 4Runner, but what are folks using to pump up the tire after repair if you are in the middle of nowhere? A regular old bicycle pump? That would work, but dang if it would not wear me out and take some time.

Couldnt imagine a bicycle pump! Maybe a triathelete could do it.
