12V double-cylinder (twin-cylinder) car air compressor

Key Specifications & Performance Features

• Airflow Rate: Typically delivers 60 to 85+ liters per minute (L/min), making it fast enough for large SUV, 4×4, truck, and van tires as well as standard passenger cars.

• Maximum Pressure: Rated up to 150 PSI (10 Bar).

• Power Connection:

  • Direct Battery Clamps (Recommended): High-output twin-cylinder units pull 18–30 Amps or more. Connecting directly to the car battery terminals prevents blowing the car’s internal 12V cigarette lighter fuse.

  • Inline Fuse: Equipped with a 20A–30A inline fuse on the power cable for circuit protection.

• Cooling & Build: Cast-aluminum cylinder heads, cooling fins, vibration-dampening rubber feet, and built-in heat sinks.

Operating Instructions & Best Practices

1. Keep the Engine Running: Always start your car’s engine before turning on the compressor. This provides a steady 13.8V–14.4V supply from the alternator and prevents draining your car battery.

2. Connect Power:

   • Attach the RED clip to the positive (+) battery terminal.

   • Attach the BLACK clip to the negative (-) battery terminal or metal engine ground.

3. Attach Hose to Valve Stem: Screw or clamp the air chuck securely onto the tire valve stem.

4. Monitor Pressure: Flip the switch to ON. Check the gauge periodically by switching the unit off briefly to get a settled pressure reading.

5. Mind the Duty Cycle: Run the unit for no more than 15 to 20 minutes continuously. Allow it to cool for 10–15 minutes before inflating additional heavy tires to prevent thermal shutdown or motor wear.
