- 12V DC Power Cord: Connects to your vehicle's 12V accessory outlet.
- Carry Handle: For easy portability.
Setup
- Position the Compressor: Place the compressor on a stable, flat surface near the item to be inflated.
- Connect to Power: Ensure your vehicle's engine is running. Insert the 12V DC power plug into your vehicle's 12V accessory outlet.
- Attach Air Hose: For tires, screw the air hose connector firmly onto the tire's valve stem. For other inflatables, select the appropriate adaptor nozzle and attach it to the air hose, then connect to the item's valve.
- Check Pressure: The integrated pressure gauge will display the current pressure of the item once the hose is connected.

Operating Instructions
- Start Inflation: Flip the power switch to the 'ON' position. The compressor will begin to inflate the item.
- Monitor Pressure: Continuously monitor the pressure gauge. Inflate to the recommended PSI (Pounds per Square Inch) for your specific item.
- Stop Inflation: Once the desired pressure is reached, immediately flip the power switch to the 'OFF' position.
- Disconnect: Unscrew the air hose connector from the valve stem. A small amount of air may escape during disconnection; this is normal.
- Repeat if Necessary: If inflating multiple items, allow the compressor to cool down between uses as per safety guidelines.
Important: Refer to your vehicle's owner's manual or the tire sidewall for correct tire pressure. For other items, consult their specific instructions.
Maintenance
- Cleaning: Wipe the compressor exterior with a damp cloth. Do not use harsh chemicals or immerse in water.
- Storage: Store the compressor and its accessories in the provided carry-case in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the air hose is not sharply bent during storage to prevent damage.
- Hose Inspection: Periodically inspect the air hose and power cord for any signs of wear, cuts, or damage. Do not use if damaged.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor does not turn on. | No power from 12V outlet; vehicle engine not running; faulty connection. | Ensure vehicle engine is running. Check 12V power plug connection. Verify vehicle's 12V outlet fuse. |
| Slow inflation or no inflation. | Air hose not securely attached; leak in hose or valve; item already at pressure. | Tighten air hose connection to valve stem. Inspect hose for damage. Ensure item requires inflation. |
| Pressure gauge appears inaccurate. | Minor variations are normal; gauge is for reference. | For precise measurements, use a separate, calibrated tire pressure gauge. |
| Compressor overheats and shuts off. | Continuous operation for too long. | Allow the compressor to cool down for at least 10 minutes before resuming operation. |
