1. Introduction
The NOCO AIR20 is a high-performance 20-amp portable air compressor with a 280-watt motor, engineered for efficient and rapid inflation. It delivers a maximum pressure of 100 PSI (6.8 bar, 689 kPa) and a maximum flow rate of 47 SLPM (standard liters per minute) or 1.66 CFM (cubic feet per minute). This device is designed for ultra-fast tire inflation, capable of inflating tires from 0 to 40 PSI in approximately 2.5 minutes (based on a 205-65R16 95H tire) and can fully inflate up to five tires in a single duty cycle. Its intelligent features, including an integrated pressure sensor and advanced Dwell technology, ensure precise inflation by automatically pausing and resuming as the set pressure is achieved, preventing over-inflation.
The AIR20 is powered directly via a 12-volt battery connection using the included clamps. It also features a digital display for easy pressure setting between 15 and 100 PSI, with selectable units (PSI, kPa, bar). For versatility, a manual mode is available for inflating items below 15 PSI, such as sports balls, bicycle tires, and inflatable toys. The unit is suitable for vehicles with tires up to 35 inches and includes a 60-lumen LED flashlight with six light modes, including an SOS function, for enhanced safety and utility.

4. Operating Instructions
Operating the NOCO AIR20 is straightforward:
- Set Desired Pressure: Use the digital display and control buttons to set your target pressure (between 15 and 100 PSI). You can switch between PSI, kPa, and bar units.
- Connect to Item: Securely attach the inflation hose with the chosen adapter to the valve stem of the tire or inflatable item.
- Start Inflation: Press the start button. The AIR20 will begin inflating and automatically stop once the preset pressure is reached, thanks to its Dwell technology.
- Manual Mode: For items requiring less than 15 PSI, activate the manual mode. Monitor the pressure manually and stop inflation when desired.
- Disconnect: Once inflation is complete, disconnect the hose from the item and then from the AIR20 unit. Disconnect the battery clamps from the power source.

Fast Inflation and Smart Pressure
The AIR20 is engineered for speed, capable of inflating a standard tire from 0 to 40 PSI in just 2.5 minutes. Its smart pressure system with Dwell technology ensures that inflation is precise and prevents over-inflation by automatically stopping at the set pressure.

LED Flashlight Functionality
The integrated 60-lumen LED flashlight offers six modes, including a standard light, a less intense light, an intermittent light, and an SOS signal. To activate, press and hold the flashlight button for 3 seconds. Subsequent short presses will cycle through the modes. Press and hold again to turn off.
5. Maintenance
To ensure the longevity and optimal performance of your NOCO AIR20, follow these maintenance guidelines:
- Cleaning: Wipe the unit with a soft, damp cloth after each use to remove dirt and debris. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the AIR20 and its accessories in the provided microfiber storage bag in a cool, dry place, away from direct sunlight and extreme temperatures.
- Hose and Cable Inspection: Regularly inspect the inflation hose and power cable for any signs of wear, cracks, or damage. Replace if necessary.
- Adapter Care: Keep all inflation adapters clean and free of obstructions.
6. Troubleshooting
If you encounter issues with your NOCO AIR20, consider the following common troubleshooting steps:
- Unit Not Powering On: Ensure the battery clamps are securely connected to a 12V power source and that the battery has sufficient charge.
- No Airflow/Slow Inflation: Check that the inflation hose is securely attached to both the AIR20 and the item being inflated. Verify that the correct adapter is used and properly sealed. Ensure the vehicle's battery is providing adequate power.
- Inaccurate Pressure Reading: Make sure the hose is properly connected and there are no leaks. The digital gauge is calibrated for accuracy, but external factors can sometimes influence readings.
- Over-inflation: The AIR20 features automatic shut-off. If over-inflation occurs, ensure the desired pressure was set correctly before starting.
For persistent issues, please refer to the detailed troubleshooting section in the full product manual or contact NOCO customer support.
