What people may not realize is that a tire inflator can be a life saver. If you're stranded in the middle of a snow storm and have a flat tire with no way to call for help, this portable air compressor can inflate that tire and get you back on your way within minutes. You can set the pressure value manually between 0-120PSI and it will stop working automatically after reaching the set value. In addition, the built-in LED light allows it to perform well at night. It's not limited to car tire inflation, but also applied to bicycles, motorbikes and different kinds of balls._x000D_
