Connecting the Air Hose and Adapters
- Screw the air hose securely onto the air outlet port of the compressor.
- Select the appropriate adapter for the item you wish to inflate (e.g., Presta valve adapter for certain bike tires, ball needle for sports balls, or the standard Schrader valve connector for car tires).
- Attach the selected adapter to the end of the air hose.

Operating Instructions
Powering On and Mode Selection
- Press and hold the power button (U) to turn on the device. The LCD screen will illuminate, displaying the current pressure and battery level.
- Press the mode button (M) to cycle through the available inflation modes: Car, Motorcycle, Bicycle, and Ball. Each mode has a default pressure setting.

Setting Desired Pressure
After selecting a mode, use the + and - buttons to adjust the target pressure. The display will show the set pressure. The device supports pressure units in PSI, BAR, KPA, and Kg/cm².
Starting and Stopping Inflation
- Connect the air hose with the appropriate adapter to the item you wish to inflate.
- Press the power button (U) to begin inflation. The compressor will start, and the display will show the real-time pressure.
- The compressor will automatically stop once the preset pressure is reached.
- To manually stop inflation, press the power button (U) again.

Using the LED Light
Press the light button (often labeled "SOS" or a light icon) to turn on the LED light. This can be used for illumination in low-light conditions or as an SOS signal in emergencies.

Direct Power from Car (12V)
If the internal battery is depleted, the compressor can be powered directly using the included 12V car power cable. Connect the cable to your car's cigarette lighter socket and to the compressor's 12V input port. Note that this cable provides power for inflation but does not charge the internal battery.

Maintenance
Cleaning
Wipe the exterior of the compressor with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure the air vents are clear of dust and debris to maintain optimal cooling performance.
Storage
Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. It is recommended to store the compressor with a partial charge to prolong battery life. Use the provided carry bag for protection.
Battery Care
To maintain battery health, avoid fully discharging the battery frequently. Recharge the device periodically if it is not used for extended periods.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on. | Low battery or no power. | Charge the device using the USB-C cable. If using the 12V car cable, ensure the car's power outlet is functional. |
| Compressor runs but no air inflates. | Air hose or adapter not securely connected. | Ensure all connections are tight. Check for blockages in the hose or adapter. |
| Inflation is slow. | Low battery or large volume item. | Ensure the device is fully charged. For very large items, inflation will naturally take longer. |
| Device gets hot during use. | Normal operation during extended use. | This is normal. The device features a triple cooling mode with 282 cooling holes and a spiral fan for heat dissipation. Allow it to cool down if it becomes excessively hot. |
| Inaccurate pressure reading. | Sensor calibration or external factors. | Ensure the connection to the tire valve is secure. Compare reading with a known accurate gauge if concerns persist. |
