Great for replacing the old, frayed or worn out charger cables. Built with 10GA copper EV cable of the highest quality with a J-1772 plug on one end and bare wires on the other end. All that is needed to replace the current worn out cable is to remove the old wires and install the new cable. Be very careful to instal the same color wires on the same terminals as those that were removed. It is a good idea to take a picture of the original wiring before removing it from the charger.
