Review on ALL-TOP Heavy Duty Air Compressor Kit - 12V Portable Inflator With 6.35CFM For Offroad And Truck Tires, Car And RV Tire Air Pump - Max 150PSI For SUV, Jeep, 4X4 Vehicles by Sam Kriegshauser

I aired up my 33" tires from 12 to 25psi seemed in about a minute or so each. I'm not used to that. I like the long hose too! No need to move the compressor around. I tested it at the shop before I took it on the trail. Good thing too. The battery was too weak to start the Jeep after airing up the tires. On the trail, I kept the engine running. The only negative is the built in pressure gauge is a joke. It's way off, like 20 psi. It pumps so fast, it is really handy. I'm looking for a liquid filled gauge to replace it. It has adapters for inflating most things, and a blower, I haven't tried those yet. This seems excellent for the price.
