I have a VIAIR 400P Portable Air Compressor that is very compact, comes in a sturdy canvas carrying bag with a coiled 30 ft. inline guage/air hose. Max Pressure is 150 psi and I routinely use it to air up my tires to 115-120 psi. I've had mine for about 6 years now with no problems at all. Check it out. If you decide to buy one, check around for the best price. I've seen quite a variation in prices for this thing. I think VIAIR also makes a 300P model which may be adequate for your needs. Good luck.
