I bought a pancake compressor from Sears, and runs on 120 volts. It fits into one of my drivers side compartments, and does not get in the way. I also bought 3 each 50' self recoiling air hoses, and a 'kit' that has a air filler, some couplings, and quick disconnects, so I can use the air filler on all tires.
This particular compressor stops at around 110 PSI, and I raised the pressure a few PSI at the pressure switch (turn the set bolt) so it now cycles off around 120 PSI. While it is slow, I only need to get 90 PSI into my tires, so it takes about 1 minute to get each full after the compressor ran, shut off, and I started using it. To get the tire completely full, I need to be holding it at the tire while it is running, so sometimes I have to release air from the tank to get it to turn on again, then need to rush to the next tire before it shuts off again.. .
Most two stage compressors rated at 175 PSI are HUGE - like on a 80 gallon tank (think your water heater at home) and require thicker steel tank wall, so they are not typically 'portable' above 135 PSI tank pressure rating.
I have not found any 12 volt DC compressors that are fast. Problem is they mostly plug into a cigarette lighter and therefore would be limited to about 12 amps input (to not exceed a typical 15 amp fuse rating). 12 amps X 12 volts = maximum about 140 watts. A 1 HP pancake compressor will draw about 7 amps at 120 volts or 840 watts! And that would be considered a 'slow' compressor compared to something found at Costco or a service station.
Good luck,
Fred.
