1. An electrical device comprising:
an electrical cable; and
a connector coupled to the electrical cable and configured to receive electrical current from an external power source, the connector including,
an RFID tag, and
an electrical storing device configured to store electrical energy from the external power source and provide electrical energy to the RFID tag when the connector is disconnected from the external power source,
wherein the RFID tag transmits a signal independent of the connector being coupled to the external power source;
wherein the electrical storage device includes a capacitor and a battery arranged in series with one another with the capacitor connected between the RFID tag and the battery, wherein the electrical cable is configured to provide electrical energy from the external power source to the battery to charge the battery and the capacitor, and wherein the capacitor is configured to discharge to the battery when the battery loses power.
