The INTELLIBOOST cables make this jump starter one of the safest on the market.
The power will not flow until the unit is hooked up correctly. It will simply beep at you if the cables are hooked up to the wrong battery terminal.
You no longer need to worry about the cables coming into contact with the metal on your vehicle either.
You can hook the INTELLIBOOST cables together once they are plugged into the jump starter and it will only beep at you in error.
No more worries!!! Safety first!!!
