Anybody has a tire pump that plug into the lighter? Does it really pump up the tire? How long does i take?

 

I've got one I got for cheap from wal-mart. It'll work in a pinch, but it'll take a while to fill a tire and kinda dies out after 30 psi. I've used it to inflate balls and such as well, but mostly I bring it along to air up tires after going off-roading in my Jeep.

If you're going to use it to inflate tires, don't bother. Get something more powerful. If it's a backup in case of a flat, then it'll work well enough to get you home.
