The jumper cable features a smart Over-Start Protection function. If you start the vehicle more than 4 times in 2 minutes, the jumper cable will turn on Over-Start Protection: The green and red light will start to blink and the battery clamps will have no output. When you disconnect the jumper cable plug from the jumper starter, the smart Over-Start Protection will reset.

The indicator on the jumper cable will show a steady green light when the battery clamps are correctly connected to the vehicle battery. If a steady red light comes on and the unit is beeping, the connection needs to be reversed.
