Operating Instructions: Jump Starting a Vehicle

Follow these steps to safely jump start your vehicle:

1. Prepare the Jump Starter: Ensure the jump starter has at least 75% charge. Connect the blue plug of the intelligent jumper cables firmly into the 12V Vehicle Starting Output (DO Port) on the jump starter. The Cable Indicator on the intelligent clamps should be off.
2. Connect to Vehicle Battery:
   • Connect the RED clip of the jumper cables to the positive (+) terminal of your car battery.
   • Connect the BLACK clip of the jumper cables to the negative (-) terminal of your car battery.
3. Start the Vehicle: Return to your car and start the engine.
4. Disconnect Cables: Once the vehicle starts, immediately remove the intelligent jumper cables from the jump starter, then disconnect the red and black clips from the car battery terminals. It is recommended to remove the clips within 30 seconds of starting the vehicle to prevent potential damage to the jump starter.

Emergency Lighting Function

The built-in LED lamp offers multiple lighting modes for various situations:

• Torch Mode (Normal Lighting): Press and hold the power button for 3 seconds to turn on a constant light. This mode is suitable for general illumination, camping, or exploring.
• Flashing Mode (Strobing): With the light on, press the power button again to activate a high-frequency flash. This can be used to attract attention or as a warning signal.
• SOS Mode: Press the power button a third time to activate the SOS signal (3 short flashes, 3 long flashes, 3 short flashes). This is a universal distress signal.

Power Bank Functionality

The jump starter can also serve as a portable power bank to charge your electronic devices:

• Connect your device's USB charging cable to the USB Output Port (5V/2A) on the jump starter.
• The jump starter can charge mobile phones approximately 4-5 times from a full charge, with an efficiency of about 50%.
• Charging a mobile phone typically takes around 2 hours, depending on the phone model.
• It is recommended to use this function primarily for urgent needs, as its main purpose is jump starting vehicles.
