I bought a nice little 12 Volt air compressor at Walmart for $50.

I never paid more than $20 for one before but this one is really very nice. It is reasonably quiet and pumps well. The 16 inch spare was down to 30 psi and this thing brought it up to 65 in 7 or 8 minutes. It didn't seem to slow down at higher pressure so I guess it is good for 80 psi anyway. The gauge on it works - no flickering of the needle and the reading is accurate. Nice long hose with a quick connect on the compressor end and a threaded tube on the other end to screw onto a valve stem.

I used a little adapter from the hardware store to change from inner to outer threads and a fitting to upsize it to standard size so I could screw on my long inflation tool which can reach into the inside wheel. I really need one with a straight end like my pressure gauge (also shown at top of photo) has, but haven't found one yet. That inflation tool works unattended (sticks onto the valve stem) but must be held onto the valve stem extenders I have. I must find an easy way to remove those extenders, which are nice for checking pressures because they don't need a cap.
