Setup
- Charge the Inflator: Before first use, fully charge the inflator using the provided Type-C USB cable and a compatible USB charger (not included) or the 12V car power adapter. The battery indicator on the display will show charging progress.
- Attach Air Tube: Screw the air tube securely onto the inflator's air outlet port.
- Select Appropriate Nozzle: Choose the correct inflation nozzle/adapter for the item you intend to inflate and attach it to the other end of the air tube.
Operating Instructions
- Connect to Valve: Securely attach the air tube with the selected nozzle to the valve of the item you wish to inflate. Ensure a tight seal to prevent air leakage.
- Power On: Long press the power button on the inflator to turn it on. The display will light up, showing the current pressure and preset target pressure.
- Select Unit and Mode: Press the 'U' button to cycle through the different pressure units (PSI, BAR, KPA, Kg/cm²) and inflation modes (Car, Motorcycle, Bike, Ball, Custom). Select the mode appropriate for your item.
- Set Target Pressure: Use the '+' and '-' buttons to adjust the target pressure to your desired level. Refer to your item's manufacturer recommendations for correct pressure.
- Start Inflation: Once the unit, mode, and target pressure are set, press the power button again to start inflation. The inflator will begin pumping air, and the real-time pressure will be displayed.
- Automatic Stop: The inflator will automatically stop once the preset target pressure is reached.
- Disconnect: Carefully disconnect the air tube from the valve. A small amount of air may escape, which is normal.
- Power Off: Long press the power button to turn off the inflator.
Using the LED Light
With the inflator powered on, short press the light button to cycle through the three LED light modes: Normal illumination, Emergency flashing, and Strobe (SOS). Press again to turn off the light.
