5. Setup
5.1 Initial Charging
Before first use, fully charge the compressor's integrated battery. Connect the provided power cord to the 230V mains socket and to the charging port on the compressor. The battery indicator lights will show the charging progress. A full charge allows for approximately 10 inflation cycles from 0 to 2 bar.
5.2 Attaching Adapters
The compressor includes three different inflation nozzles. Select the appropriate nozzle for the item you wish to inflate (e.g., needle for balls, small cone for inflatables, or the standard Schrader valve connector for car/bicycle tires). Attach the chosen nozzle securely to the end of the inflation hose.

6. Operating Instructions
6.1 Inflating Tires/Items
- Connect the Hose: Screw the inflation hose connector firmly onto the tire valve or attach the appropriate adapter to the item to be inflated.
- Power On: Press the yellow power button (often labeled with a power symbol) to turn on the compressor. The digital display will illuminate and show the current pressure.
- Select Unit: Press the 'UNIT' button (often labeled with a circle and arrows) to cycle through the pressure units: PSI, BAR, or KPA. Select your desired unit.
- Set Desired Pressure:
- Press and hold the '+' button for approximately 5 seconds until the displayed pressure value starts flashing. This indicates you are in setting mode.
- While the value is flashing, use the '+' and '-' buttons to adjust the target pressure to your desired level.
- Once the desired pressure is set, stop pressing buttons. The flashing will cease after about 5 seconds, and the compressor will memorize this target pressure. The display will revert to showing the current pressure.
- Start Inflation: Press the yellow power button again to start the inflation process. The compressor will automatically stop once the preset pressure is reached.
- Disconnect: Unscrew the hose from the valve. A small amount of air may escape, which is normal.

6.2 Using as an External Power Source
The compressor can also function as a portable power bank:
- USB Charging: Connect your smartphone, tablet, or other USB-powered device to one of the two 5V USB ports (100mA output).
- 12V Power: Use the two 12V cigarette lighter sockets to power compatible 12V devices (e.g., portable coolers, other small compressors).
6.3 Using the LED Light
Press the dedicated LED light button (often labeled with a light bulb symbol) to turn on the integrated LED lights for illumination in dark environments.
7. Maintenance
Proper maintenance ensures the longevity of your compressor:
- Cleaning: Wipe the exterior of the compressor with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the compressor in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the hose and adapters are neatly stored.
- Battery Care: For optimal battery life, recharge the compressor periodically if it's not used for extended periods.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor does not turn on. | Battery is depleted. | Recharge the compressor's battery. |
| Slow inflation. | Low battery charge. Leak in hose connection. | Ensure battery is fully charged. Check and tighten all connections. |
| Compressor stops prematurely. | Preset pressure reached. Overheating protection activated. | Verify the preset pressure. Allow the unit to cool down before resuming operation. |
| Inaccurate pressure reading. | Loose connection to valve. Sensor calibration. | Ensure the hose is securely attached to the valve. If persistent, contact customer support. |
