3. For direct 12V power, plug the car adapter into the inflator's power port and the other end into your vehicle's 12V accessory socket.

4.2 Inflating a Tire

1. Power On: Press the power button. The digital display will illuminate.
2. Select Mode: Press the mode button to cycle through the options: Car, Motorcycle, Bicycle, Ball, or Manual (displayed as "N").
3. Set Pressure (if needed): In Manual mode, use the "+" and "-" buttons to set your desired pressure in PSI. Pre-set modes have a default target pressure.
4. Connect to Valve: Remove the tire's valve cap. Press the brass inflation chuck firmly onto the valve stem. You will hear a brief hiss of air when the connection is secure.
5. Start Inflation: Press the start button. The display will show the real-time pressure increasing.
6. Automatic Stop: The inflator will beep and stop automatically when the target pressure is reached.
7. Disconnect: Quickly remove the inflation chuck from the valve stem and replace the valve cap.

4.3 Using the 12V Car Adapter

Ensure your vehicle's engine is running before using the 12V adapter to prevent draining the car battery. Plug the adapter into the inflator and the car socket. The operation steps are identical to battery-powered use.
