Its lightweight and compact size make it effortless to carry on your rides. - FAST INFLATION: Save time with efficient inflation at 15 L/minute, reaching 80 PSI (for 70025C road tires) in just 50 seconds. Get back on the road quickly and continue your cycling enjoyment without long interruptions. - QUICK CHARGING & POWERFUL PERFORMANCE: Charge the pump fully in just 30 minutes via Type-C USB. Once fully charged, it can inflate at least three 70025C tires from 0 to 120 PSI, ensuring you have the power you need when on the go. - DUAL NOZZLE COMPATIBILITY: This mini bike pump is equipped to handle both Schrader and Presta valves, eliminating the need for any additional adapters or head changes.
