The Trek Air Rush Electric Bike Pump is a small electric air pump for bike tires. Fit it in a pocket, saddlebag, or backpack, and fix flats quickly when out on a ride.

No need for physical exertion, and includes Presta, Schrader, and needle valve adapters so you can inflate your friend's bike tires as well.
