4. Setup
4.1 Charging the Pump
Before first use, fully charge the pump. Connect the provided Type-C charging cable to the pump's charging port and a suitable USB power adapter (not included). The indicator light will be red during charging and turn green when fully charged. A full charge takes approximately 25 minutes.
4.2 Attaching the Air Hose and Valve Adapters
Screw the air hose securely onto the pump's air outlet. Identify the valve type of your tire (e.g., Presta, Schrader). Use the appropriate adapter if necessary. The pump supports multiple valve types.

Note: Actual performance may vary depending on environmental conditions and tire status.
6. Maintenance
- Cleaning: Wipe the pump's exterior with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the pump in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: To maintain battery health, charge the pump regularly, even if not in frequent use. Avoid completely draining the battery for extended periods.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on. | Low battery or no charge. | Charge the pump fully using the provided Type-C cable. |
| Pump is not inflating. | Incorrect hose connection, wrong valve adapter, or target pressure already met. | Ensure the air hose is tightly screwed on. Verify the correct valve adapter is used and securely attached to the tire valve. Check the set pressure; if it's lower than current tire pressure, increase it. |
| Loud noise or vibration during operation. | Normal operation characteristic. | This is typical for compact air pumps. If noise is excessive or unusual, discontinue use and contact support. |
| Pump gets hot during use. | Normal during prolonged inflation. | Allow the pump to cool down between extended inflation cycles. |
| Air leaks when detaching the hose. | Slight air loss is common during detachment. | Detach the hose quickly and smoothly to minimize air loss. |
| Pump shows error or doesn't start when connected to a pressurized valve. | Some pumps require connection to an unpressurized valve or specific sequence. | Try connecting the hose to the tire valve before turning on the pump or setting the desired pressure. |
