Thanks for the suggestions. I ended up ordering this Wolfbox 4000a boost/compresser:

4000a should be overkill for anything I require but having the extra juice and larger battery is nice. They were all on sale for Amazon Days.
I gave up on trying to find a good small-sized compressor so I do have a couple small handpumps and will toss one in my saddlebag along with the tire kit/C02 cans.
