Abstract
An adapter including an associated battery capable of powering an electronic device. The power adapter typically includes the battery as an integral component that is connected to a plug or other interface capable of mating with a power source, such as a wall socket. Thus, the adapter battery may provide power either to operate the device or charge a battery within (or otherwise associated with) the device even if the adapter is not connected to a power source.
