The bags take a very small volume of air to inflate. I just use a Sears Craftsmen 19.2V C3 Cordless Inflator (Tried to post link but it is being blocked.
Uses the same 19.2V batteries as my cordless drill for jacks and impact wrench for lugnuts, sawzall for overhanging branches and wet & Dry dustbuster vacuum for the camper.
I ran the airlines back to back bumper and they replace the rear license plate screws. I really like the bags both loaded and levelled and unloaded when you don't notice them there.
