depends on your air source, I use the free ones at a local gas station, gets the tank to 75 psi in maybe two or three minutes. It seems like forever when your holding the chuck on but it really isnt too long. I'll take it to a little over 100 psi with my portable compressor.
$20 for a portable craftsman tank and a few bucks in fittings works for me till i can afford a compressor for it.
I did start a little write up about it and never did post pictures I guess
