1. A supplementary power supply, comprising:
- a first connector configured to couple to a host device;
a second connector configured to couple to a peripheral device;
a first power source configured to provide electrical power to the peripheral device via the second connector;
a path configured to allow data to pass between the host device and the peripheral device; and
a switch configured to receive power from the host device, wherein the switch in a first position directs the power from the host device to the peripheral device, and the switch in a second position directs the power from the host device to a reference voltage circuit.

Abstract
A supplementary power supply for a peripheral device is provided. The supplementary power supply comprises a first connector, a second connector, a power source, and a path. The first connector is operable to couple to a host device. The second connector is operable to couple to the peripheral device. The power source is operable to provide electrical power to the peripheral device via the second connector. The path is operable to allow data to pass between the host device and the peripheral device. A method for providing electrical power to a peripheral device is also provided.
