Operating Instructions
Jump Starting a Vehicle
Safety First: Ensure your vehicle's ignition is off and the parking brake is engaged. Wear appropriate safety gear, such as gloves and eye protection.
- Insert Jumper Cable: Insert the smart jumper cable plug into the jump starting port on the BSMOOM unit.

- Start Engine: Once connected, turn on your vehicle's ignition to start the engine.
- Remove Clamps: Immediately remove the clamps from the car battery once the engine starts, then disconnect the jumper cable from the jump starter unit.

Force Start Function (for severely discharged batteries)
If the vehicle battery is extremely low and the jump starter does not automatically detect it, you may use the force start function:
- Connect Clamps: Connect the clamps to the car battery as described above.
- Activate Force Start: Press and hold the "OK" button (or designated force start button) on the jump starter for more than 3 seconds.
- Start Engine: Start the car engine within 30 seconds after activating force start.

Using the Portable Air Compressor
The device can inflate tires, bicycle tires, balls, and even swimming rings with a maximum pressure of 160 PSI.
- Connect Air Hose: Screw the air hose into the inflatable interface on the jump starter unit and attach the appropriate air nozzle to the item you wish to inflate.
- Power On & Select Mode: Press and hold the "OK" key to power on. Press the "M" key to switch between inflation modes (Car, Motorcycle, Bicycle, Ball, Custom).

Troubleshooting
If you encounter issues with your BSMOOM Jump Starter, refer to the following common problems and solutions:
- Device not turning on: Ensure the device is charged. If the battery is completely drained, it may take a few minutes of charging before it responds.
- Car not starting:
- Check that the jumper cable clamps are securely connected to the correct battery terminals (red to positive, black to negative).
- Ensure the jump starter has sufficient charge.
- If the battery is severely discharged, try using the "Force Start" function.
- Verify that the vehicle's battery voltage is 12V.
- Air compressor not inflating:
- Ensure the air hose is securely connected to both the device and the inflatable item.
- Check that the correct inflation mode and target pressure are set on the display.
