E-Booster Digital Pump

Introducing the all-new electric pump. Its innovative design allows you to preset the pressure, and with just a simple press, you can easily achieve the desired tire inflation. Fits both Presta and Schrader valves. The included storage bag makes it easy to carry wherever you go. * For TPU inner tubes with resin valves, be sure to use an extender hose to prevent the valve from overheating and melting. * If the tire already has air pressure, please activate the inflation switch before connecting the valve.
