Setup
1. Initial Charging
Before first use, fully charge the air pump. Connect the provided USB-C charging cable to the device's charging port and plug the other end into a suitable USB power adapter (not included). The digital display will indicate charging status. A full charge typically takes 3-4 hours.
2. Attaching the Inflation Hose
Screw the inflation hose securely onto the inflation port of the air pump. Ensure it is tightened to prevent air leakage.
3. Selecting the Correct Nozzle
Choose the appropriate nozzle adapter for the item you intend to inflate. Screw or push the adapter onto the end of the inflation hose.
Operating Instructions
1. Powering On/Off
Press and hold the Power button for a few seconds to turn the device on. The digital display will illuminate. To turn off, press and hold the Power button again.
2. Selecting Pressure Unit
With the device on, press the "Unit" button (labeled Psi Bar Kpa) to cycle through available pressure units: PSI, BAR, KPA.
3. Setting Target Pressure
Press the "Mode" button (C) to select a preset inflation mode (e.g., car, motorcycle, bicycle, ball). Each mode has a default target pressure. Alternatively, use the "+" and "-" buttons to manually adjust the desired target pressure.
4. Connecting to Item for Inflation
Connect the chosen nozzle adapter to the valve of the item you wish to inflate. The digital display will show the current pressure of the item.
5. Starting Inflation
Once the target pressure is set and the hose is connected, press the Power button to start inflation. The pump will automatically stop when the target pressure is reached.

Troubleshooting
- Device does not turn on:
Ensure the battery is charged. Connect to a power source and try again after a few minutes.
