Anyone know how hard it is to put 125 psi into one of these things and how long it would take with a $10 12 volt compressor if it's even possible. From my experience, it doesn't seem likely that it would work very well because a little compressor like that isn't designed to run for long periods and I imagine it might take a long long time to fill it up to 100 psi even.
I paid 50 cents at a gas station and used their air but it only lasted for about 4 or 5 minutes and I only got it up to about 45 psi or so, which is a long long way from 100 which is where I wanted.
I was also just curious if the 7 gallon tank were really filled up to 100 psi, how many tires could it fill up? If I were just topping off starting at 25 psi and going to 30, how many tires could I top off?
