It's like a cordless drill, except desirable for use on a tire. That is, when applied the automatic inflator will shoot air into the tire instead of puncturing it and letting air out. Though using a cordless drill for the second thing could serve as quick and easy revenge on the high school nemesis you saw for the first time in 10 years the other day. He was pulling out of a gas station. He called you "Moobs" until you lost 20 pounds in 11th grade. Then he called you "Bee sting Moobs."
The cordless tire inflator charges via an included AC adapter or DC car charger, and functions for hours on a full battery. It has a built-in digital pressure gauge that displays in psi, kpi, or bar, and automatically shuts off when it reaches your desired tire pressure. An integrated LED for illuminating tire valves and a 5" long air hose make it simple to use day or night, and on any type of tire. From flat, the cordless inflator will fill an automobile tire to 36 psi in minutes, and a bicycle tire to 58 psi in 1 minute.
