1. An apparatus comprising:
- a chemical-to-electrical power source configured to supply DC power;
a power outlet coupled to the power source and configured to receive an AC power plug coupled to a device; and
an authorization detection component configured to—
communicate with the device to detect whether the device is authorized to receive DC power, based on electrical characteristics of the device,if the device is authorized to receive DC power, permit the power outlet to supply the DC power from the chemical-to-electrical power source to the device via the AC power plug, andif the device is not authorized to receive DC power, prevent the power outlet from supplying the DC power from the chemical-to-electrical power source to the device.
