7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Battery is depleted. | Charge the device using the USB-C cable or connect to a 12V car power source. |
| Inflation is slow or not working. | Air hose not securely connected; nozzle adapter incorrect; target pressure too low. | Ensure hose is tightly screwed onto valve. Use correct adapter. Verify target pressure setting. |
| Device overheats. | Prolonged continuous operation; obstructed heat emission holes. | Allow the device to cool down. Ensure heat emission holes are clear. Avoid continuous operation for more than 10-15 minutes. |
| Inaccurate pressure reading. | Loose connection; sensor issue. | Re-connect the air hose securely. If issue persists, contact support. |
