Add the perfect amount of air to your tires with the Comp 02 tire inflator from Slime®. Designed with a standard Shrader® valve head, this inflator is compact, plugs into a 12V socket, and includes a pressure gauge. For additional versatility, it comes with ball and raft adapters.
I also find it very convenient for keeping my car tires at the recommended pressure. It is not as fast as at a gas station, but with the money saved it pays for itself over time.
Built in pressure gauge is a big plus and the schrader valve attachment makes for quick and easy attachment and removal to valve stem.
