This cordless rechargeable inflator is something you definitely are gonna need it! I've tried so many inflators before this one, they are nothing when comparing to this kind. I like the way it works, which doesn't bother you to find a power connector what so ever, you can just put it in your trunk when you don't need it. The battery is rechargeable, so you don't need to worry about connect to your car.
For occasions, you can inflate balloons without finding a car. Also, did I mention about the power it has? It is 150psi when it fully charge, which means you can inflate your all tires quickly.
