I have a 5 gallon air tank that I take out to the airport with me. Bought
it
before I got in the hangar, there was no electric at the tiedowns and they
don't let cars in.

You don't need a car *or* electrical with the portable air pump we've got.
It's basically a big rechargeable battery with an air pump built around it.

We use it a LOT.
