Mini Portable Electric Bike Pump with Digital Screen 120PSI and Fast Charging for Road Tires | Lersk

Mini Portable Electric Bike Pump with Digital Display, 120PSI Max Pressure, 450mAh Battery and 30-Minute Fast Charging

Compact cordless tire inflator designed for road bikes — 130g and small enough to carry in a jersey pocket or bag. Inflates a 700×25C road tire from 0 to 110PSI in a single charge cycle. USB Type-C fast charging reaches full battery in 30 minutes. Digital display shows real-time pressure and remembers your last target pressure setting on next startup.

Pressure Memory Function Remembers the last pressure setting used — powers on directly to your preferred target value without needing to reset each time.

Real-Time Pressure Display Digital screen shows live pressure reading during inflation. Auto shuts off when target pressure is reached — pressure fluctuation stays within ±1PSI after shutoff while the nozzle remains connected.

450mAh Fast Charge Battery 7.4V / 450mAh battery charges fully in 30 minutes via USB Type-C at 5V 1.5A. Provides approximately 2 full inflation cycles at 110PSI per charge.

Auto Power-Off Automatically shuts down after 1 minute of inactivity in non-inflating state to preserve battery life.
