4.1 Charging the Pump
Before initial use, fully charge the pump. Connect the provided USB Type-C charging cable to the pump's charging port and to a standard USB power adapter (not included). The LED display will indicate the battery level. A full charge for the 500mAh battery typically takes approximately 1.5 hours.

4.2 Attaching the Valve Adapter
The pump is compatible with both Schrader and Presta valves. You can use the pump directly or with the included elastic air hose.
- For Schrader Valves: The pump's direct connection or the hose end with the larger opening is typically used. Ensure the Schrader valve kit (air nozzle thimble) is correctly installed if using the hose.
- For Presta Valves: Use the Presta valve converter or the hose end with the smaller opening. Ensure the Presta valve is opened before connecting the pump.
