An electronic charging cable assembly is disclosed. The assembly includes a power connection end adapted to be electrically connected to an electrical power source and a device connection end adapted to be logically connected to an electronic device. The device connection end is electrically connected to the power connection end. A light source is located at the device connection end such that, when the power connection end is electrically connected to the electrical power source and the device connection end is not connected to the electronic device, the light source is illuminated and, when the power connection end is electrically connected to the electrical power source and the device connection end is connected to the electronic device, the light source is not illuminated. An exemplary electrical circuit used to provide this feature and a method of operating the electronic charging cable assembly are also disclosed.
