5. Setup
Follow these steps to set up your CARSUN Portable Air Compressor:
-
Start your car engine: Ensure your vehicle's engine is running to provide stable power to the compressor.
-
Connect the air hose nozzle: Tightly connect the air hose nozzle to the valve stem of the tire or item you wish to inflate.
-
Connect to power: Plug the 12V car cigarette lighter power cable into your vehicle's cigarette lighter socket.

6. Operating Instructions
The air compressor features a digital display and intuitive controls for easy operation.
-
Select Mode: Press the 'M' button to cycle through the five available inflation modes: Ball, Bicycle, Motorcycle, Car, and SUV. Each mode has a recommended preset pressure.
-
Set Pressure: Use the '+' and '-' buttons to adjust the target inflation pressure. The unit supports PSI, BAR, KPA, and kg/cm².
-
Start Inflation: Once the desired pressure is set, press the 'Switch Key' (power button) to begin inflation.
-
Automatic Stop: The compressor will automatically stop when the preset pressure is reached, preventing over-inflation.
-
LED Light: Press the 'Illuminated Key' (light bulb icon) to turn on the built-in LED flashlight for use in low-light conditions.

Tire Pressure Memory Function
The device saves the last used tire pressure value automatically. You can either select this stored value or set a new one according to your needs. Recommended tire pressures are:
- Car tire pressure: 2.3 ~ 2.5 bar
- Motorcycle tire pressure: 1.8 ~ 3.0 bar
- Bicycle tire pressure: 30 ~ 65 psi

Quick Inflation with Auto-Stop
The CARSUN air compressor is designed for quick replenishment, automatically stopping inflation once the target pressure is reached. This prevents overcharging and potential tire puncture.
7. Maintenance
-
Cleaning: Wipe the exterior of the compressor with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
-
Storage: Store the power cord and inflatable tube in their designated compartments on the unit to prevent tangling and damage. Keep the compressor in a dry, cool place away from direct sunlight and extreme temperatures.
-
Inspection: Periodically check the air hose and power cable for any signs of wear or damage. Replace if necessary.
8. Troubleshooting
-
Compressor does not turn on: Ensure the 12V power plug is securely inserted into the car's cigarette lighter socket and the car engine is running. Check for any blown fuses in your vehicle's cigarette lighter circuit.
-
Slow inflation or no inflation: Verify that the air hose nozzle is tightly connected to the valve stem. Check the air hose for any kinks or leaks. Ensure the correct mode and pressure are selected.
-
Inaccurate pressure reading: Ensure the nozzle is fully seated on the valve stem without any air leakage. If readings consistently seem off, try re-attaching the nozzle.
-
Overheating: If the unit feels excessively hot, turn it off and allow it to cool down for at least 15-20 minutes before resuming use. Avoid continuous operation for more than 30 minutes.
9. User Tips
