If you drive your car to the track like I do (as opposed to trailering it), what do you use for an air supply to pump up your tires before driving home, if the track doesn't have an onsite air compressor?

Believe it or not, I've used a high-volume bicycle tire pump in the past when necessary, (about 10 pumps per 1 psi in a car tire), but am now looking at options like a portable air tank or tire inflators that can plug into the car's 12v lighter socket.

Thx
