Very glad I found this compressor. This compressor can be powered by a car battery. The compact size is ideal for transporting an ATV or in a tool box. We used this unit on our 5 acre property where most homes are out of reach of an extension cord. The device is able to quickly inflate all types of tires. The device inflated the tractor tire shown in the video in less than 2 minutes, even with a punctured tire. This allowed us to bring it back to the shed for repairs with no further damage to the tire. The device comes with a flexible carrying case, but I bought a can of ammo to safely secure and store the contents and to be able to mount it on a tractor. I fully expect to buy more units for friends with quads.
