Abstract: The invention seeks to solve the problem of theft or “borrowing” of a charging device to deprive the owner of the device when needed. This can be done by using Bluetooth or other protocol to “pair” a charger to the device being charged and locking or otherwise disabling the charger except when properly paired so that only the owner of the charger can make use of it. The charger can be enabled electronically only when properly paired. Also, when the adapter and the cable are physically detachable the device can also be optionally provided with electro-mechanical or other locking means for securing the cable to the adapter so that it cannot be separated from the charger except when paired.
