Why does the screen show 'Error Code 2'?
It means your car battery voltage is below 8V, and you might need to use 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 the 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.
