This is equipped with a large on/off button for easy operation. The flat, solid design of the TyreInflate200 keeps the device stable during operation. Powered by a 3m cable, the TyreInflate200 plugs into a 12v socket in the car and makes it easy to reach all the tyres around the vehicle. Displays pressure values in kPA, bar and PSI. Includes storage compartment for tire valve caps. Additionally, this includes a 3-piece adapter for bicycle tires, motorcycle tires, balls and other inflatable items. The portable, analog car air pump is the perfect companion for on-the-go, flat tire or a loss of tire pressure. Fully inflates a tire in up to 4.5 minutes (based on inflating a 13" tire without air to 2.41 bar).
