5. Safety & Important Notices
Warnings
- NOT SUITABLE FOR LARGE VEHICLES: This compressor is not designed for large vehicle tires such as those on campers, trucks, trailers, or off-road vehicles.
- NOT SUITABLE FOR LARGE INFLATABLES: This is a high-pressure, low-flow pump. It is not suitable for inflating large items like air mattresses, inflatable pools, or floating beds, which require a low-pressure, high-flow pump.
- NOT SUITABLE FOR ELECTRIC SCOOTERS: The product information states it is not suitable for electric scooter tires.
- AUTO SHUT-OFF: If the machine is powered on but not actively inflating, it will automatically shut off after 90 seconds to conserve battery.
- Do not operate the compressor continuously for extended periods beyond its stated capacity. Allow it to cool if necessary.
- Keep the compressor and its components away from water and excessive heat.
6. Care & Maintenance

7. Troubleshooting
| Problem |
Possible Cause |
Solution |
| Compressor does not turn on. |
Battery is depleted. |
Connect the Type-C cable and charge the unit fully. |
| Inflation stops before reaching target pressure. |
Auto shut-off timer activated (90 seconds of inactivity). |
Ensure the nozzle is properly sealed on the valve and restart inflation. |
| Pressure reading seems inaccurate. |
Poor seal on valve; sensor error. |
Re-seat the nozzle on the valve. Accuracy is ±2 PSI. |
| Compressor turns off during use. |
Overheating or battery protection. |
Allow the unit to cool down for 10-15 minutes before resuming. |
| Air is leaking from the connection. |
Wrong nozzle or damaged seal. |
Ensure the correct nozzle is used and attached securely. Inspect the O-ring on the nozzle. |
