4. Setup
4.1 Charging the Device
Before first use, fully charge the air pump. Connect the provided Type-C charging cable to the charging port on the device and plug the other end into a compatible 5V/1A USB power adapter (not included). The battery level display will indicate charging status.
4.2 Attaching the Nozzle
Select the appropriate inflation nozzle from the 4-piece set for your item (e.g., car tire, bicycle valve, ball needle). Screw the chosen nozzle securely onto the air hose. Then, connect the air hose to the inflation port on the air pump.
5. Operating Instructions
5.1 Power On and Preset Pressure
- Press the power button to turn on the device. The digital display will show the current pressure.
- Use the control buttons (usually '+' and '-') to set your desired target pressure. The unit supports a range of 3-150psi.
- The device features a preset pressure function, allowing you to set the desired PSI, and it will automatically stop once that pressure is reached.
5.2 Inflation Process
- Connect the attached nozzle to the valve of the item you wish to inflate. Ensure a secure connection to prevent air leakage.
- Once the desired pressure is set, press the start button to begin inflation.
- The pump will automatically stop when the preset pressure is reached.
- Disconnect the nozzle from the item and the hose from the pump.
5.3 Using Lighting Functions
The product is equipped with lighting and flashing light functions for use in low-light conditions or emergencies. Refer to the specific button on your device for activating these features (usually a dedicated light button or a long press of the power button).
5.4 Multi-purpose Inflation
The included nozzle set allows for inflation of various items:
- Car Tires: Use the standard tire valve adapter.
- Motorcycle Tires: Use the appropriate adapter for motorcycle valves.
- Bicycle Tires: Use the correct adapter for Presta or Schrader valves as needed.
- Inflatable Balls: Use the needle adapter for sports balls.
6. Maintenance
- Keep the device clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Store the air pump and its accessories in the provided storage bag in a cool, dry place when not in use.
- Avoid exposing the device to extreme temperatures or direct sunlight for prolonged periods.
- Ensure the charging port and inflation ports are free from obstructions.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on | Low battery or no charge. | Charge the device fully using the Type-C cable. |
| Inflation is slow or not working | Nozzle not securely attached; incorrect pressure setting; air leakage. | Ensure nozzle is tightly screwed. Check for leaks. Verify preset pressure is within range. |
| Cannot set pressure | Incorrect mode or button usage. | Refer to the operating instructions for specific button functions to adjust pressure. Ensure the device is powered on. |
| Device stops prematurely | Preset pressure reached; low battery. | This is normal if preset pressure is reached. If not, check battery level and recharge. |
8. User Tips
- Pressure Setting: To set the pressure, ensure the device is on. Use the '+' and '-' buttons to adjust the target PSI. The device will automatically stop when this pressure is reached.
- Battery Life: For optimal performance, ensure the device is fully charged before long inflation tasks. The battery level indicator helps monitor remaining power.
- Nozzle Selection: Always use the correct nozzle for the item you are inflating to ensure efficient and safe operation.
