This image demonstrates the process of connecting the BUVAYE BN03 jump starter to a vehicle's battery terminals, showing the red clamp on the positive terminal and the black clamp on the negative terminal.
- Ensure the BUVAYE BN03 is sufficiently charged.
- Turn off the vehicle's ignition and all accessories.
- Connect the smart jump starter clamps to the jump start port on the BUVAYE BN03.
- Connect the red (positive) clamp to the positive (+) terminal of the vehicle's battery.
- Connect the black (negative) clamp to the negative (-) terminal of the vehicle's battery.
- Ensure the clamps are securely attached and the indicator light on the smart clamp is green. If it's red or flashing, check connections and battery status.
- Start the vehicle's engine.
- Once the engine starts, immediately remove the smart clamps from the vehicle battery, first the negative (black) clamp, then the positive (red) clamp.
- Disconnect the smart clamps from the BUVAYE BN03.
Note: If the vehicle does not start after 3 attempts, allow the jump starter to cool down for a few minutes before trying again. Consult your vehicle's manual for specific jump-starting procedures.
2. Inflating Tires

- Connect the inflator hose to the inflator hose socket on the BUVAYE BN03.
- Attach the other end of the inflator hose to the tire valve. Ensure a secure connection to prevent air leakage.
- Turn on the BUVAYE BN03. The display will show the current tire pressure.
- Use the "Air Pressure +/-" buttons to set the desired target pressure. Press the "Pressure Unit Adjustment" button to cycle through units (PSI, KPA, BAR, KG/CM²).
- Press the start button (often the power button or a dedicated inflation button) to begin inflation.
- The device will automatically stop when the preset pressure is reached.
- Disconnect the inflator hose from the tire valve and then from the BUVAYE BN03.
Memory Function: After powering on, press "+" or "-" to recall the last set inflation mode and pressure value.
Note: For continuous inflation, allow the device to cool down for 10 minutes after each inflation cycle to prevent overheating.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on. | Battery is depleted. | Charge the device fully using the USB-C cable. |
| Vehicle does not jump start. | Incorrect clamp connection; vehicle battery too low; jump starter battery too low. | Ensure clamps are connected correctly (red to +, black to -). Fully charge the jump starter. If the vehicle battery is severely discharged, it may require professional assistance. |
| Tire inflator not working or slow. | Hose not securely connected; target pressure not set; device overheating. | Check hose connections. Set the desired pressure. Allow the device to cool down if it has been used continuously. |
| Smart clamp indicator light is red or flashing. | Incorrect connection; short circuit; reverse polarity; battery fault. | Disconnect and reconnect clamps, ensuring correct polarity. Check for any short circuits. If the issue persists, the vehicle battery may be faulty. |
