6. Operating Instructions
6.1. Jump Starting a Vehicle
Follow these steps to safely jump start your 12V vehicle:
- Insert the Jumper Cable: Plug the smart jumper cable connector firmly into the jump starter's port.
- Connect to Car Battery:
- Attach the RED (+) clamp to the positive terminal of the car battery.
- Attach the BLACK (-) clamp to the negative terminal of the car battery.
Ensure the clamps make good contact with the battery terminals. The smart clamps will provide visual and audible feedback if there are incorrect connections or issues.
- Start the Engine: Go into your vehicle and start the engine.
- Remove Clamps: Once the vehicle starts, immediately remove the smart clamps from the car battery, then disconnect the jumper cable from the jump starter.

6.2. Using as a Power Bank
The jump starter can charge your electronic devices:
- Connect your device's USB charging cable to one of the jump starter's USB output ports (Output 1: QC3.0, Output 2: 5V/2.4A).
- For models with wireless charging (e.g., BIUBLE 2500A), ensure the "ON/OFF" button is activated and place your compatible smartphone on the designated wireless charging area. For optimal charging, align the device to the center of the jump starter. Note that thick phone cases may affect wireless charging efficiency.
- Some models (e.g., BM300) may feature a 12V/10A DC output (max 160W) for powering car accessories like vacuum cleaners or refrigerators.

6.3. Using the LED Flashlight
The integrated LED flashlight offers four modes:
- Lighting: For general illumination.
- Strobe: A flashing light for signaling or attracting attention.
- SOS: Emits the international Morse code signal for distress.
- Warning: A specific warning light pattern.
Refer to your specific model's manual for instructions on how to cycle through these modes, usually by pressing the power/light button multiple times.
7. Maintenance
Proper maintenance ensures the longevity and reliability of your jump starter:
- Recharge After Use: Always fully recharge the jump starter after each use.
- Regular Charging: If not used for a long period, it is recommended to charge the jump starter once every three months to maintain battery health and prolong its service life.
- Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. The optimal working temperature range is -20℃ to 60℃ (-4℉ to 140℉).

8. Troubleshooting
If you encounter issues, refer to the following common problems and solutions:
8.1. Red Light On or Beeping from Smart Clamps
This indicates a potential issue with the connection or battery:
- Check Clamp Connection: Ensure the clamps are connected correctly (Red to positive, Black to negative).
- Ensure Full Contact: Make sure the clamps have full and clean contact with the battery terminals. Clean any dirt or oil stains from the terminals if necessary.
- Vehicle Boot Protection: Some cars have a boot protection system. Ensure the car's doors or boot are closed.
- If the issue persists after checking these points, the vehicle battery might be severely damaged or the jump starter might require service.
8.2. Cannot Jump Start the Vehicle
If the vehicle does not start:
- Incorrect Voltage: Confirm that the vehicle is a 12V system. This jump starter is not compatible with other voltages.
- Low Jump Starter Battery: Ensure the jump starter itself is sufficiently charged.
- Severely Discharged Vehicle Battery: If the vehicle battery has been dormant for a very long time or is completely dead, the jump starter may not be able to revive it.
- Retry: If the car starter does not work the first time, wait 3-4 minutes and repeat the operation.
