Why does the screen show 'Error Code 2'?
It means your car battery voltage is below 8V, and you might need the Force Start function.
4 Steps to use the Force Start Function:
Step 1: Insert the battery clamps into the jump starter and attach the clamps to the car battery.(The screen may display 'Error Code 2' or won't display any instructions.)
Step 2: Press Power Button and Flashlight Button simultaneously for 2-3 seconds to start the force output.
Step 3: Start the car engine.
Step 4: Remove the clamps from the car battery.
Warning: Please be cautious to use the Force Start Function. When using the Force Start function, auto-detection and safety features will be disabled. Please ensure a correct connection.
