The green light on the INTELLIBOOST cables turns solid green to indicate that the jump starter is properly connected to a vehicle and is ready to boost.
When the green light is on, it means power is flowing from the jump starter to the vehicle and you can go ahead and start the vehicle.
The green light comes on when the INTELLIBOOST senses a draw from the vehicles electrical system.
In most boosting scenarios, this green light will come on when you first connect the jump starter to the vehicle battery. If it does not, don’t worry, just go ahead and start the vehicle.
As soon as you turn the key/press the button to start it, INTELLIBOOST will sense the draw from the starter and send power to get you going.
