Setup
- Charge the Device: Before first use, fully charge the LEXIN P4 using the provided USB-C charging cable. Connect the USB-C end to the inflator and the USB-A end to a compatible power source (e.g., wall adapter, car charger, power bank). The digital display will indicate charging status.
- Attach Air Hose: Screw the inflation air tube securely into the designated port on the top of the inflator.
- Select Adapter: Choose the appropriate adapter (Presta valve, ball needle, or inflatable nozzle) for the item you intend to inflate and attach it to the end of the air tube.
Operating Instructions
- Power On: Press the power button (usually marked with a power symbol) to turn on the inflator. The digital display will light up.
- Select Mode: Press the mode selection button (often an icon representing different items like car, motorcycle, bike, ball) to cycle through the preset inflation modes. The display will show the recommended pressure for each mode.
- Set Target Pressure: Use the '+' and '-' buttons to adjust the target pressure if you are not using a preset mode or wish to customize it. The real-time pressure will be displayed as you inflate.
- Connect to Valve: Securely connect the air tube with the selected adapter to the valve stem of the item you are inflating. Ensure a tight seal to prevent air leakage.
- Start Inflation: Press the start button (often the power button again or a dedicated play/start button) to begin inflation. The inflator will automatically stop once the preset target pressure is reached.

Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use harsh chemicals or abrasive materials.
- Storage: Store the inflator in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided storage bag to protect it from dust and damage.
- Battery Care: For optimal battery life, charge the device regularly, even if not in frequent use. Avoid fully discharging the battery for extended periods.
Troubleshooting
- Device Not Turning On: Ensure the battery is charged. Connect to a power source and allow it to charge for a while before attempting to power on again.
- Inflator Not Inflating: Check that the air tube and adapter are securely connected to both the inflator and the item's valve. Ensure the target pressure is set above the current pressure.
- Inaccurate Pressure Reading: Ensure the adapter is tightly sealed to the valve. Slight pressure drops may occur when disconnecting the hose, which is normal.
- Over/Under Inflation: The auto-stop feature is designed to prevent this. If it occurs, double-check your preset pressure and ensure the device is functioning correctly.
