What is claimed is: 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. 2. The supplementary power supply of claim 1, wherein the electrical power provided by the first power source supplements electrical power provided to the peripheral device by the host device. 3. The supplementary power supply of claim 1, wherein the first power source is at least one of a disposable battery and a rechargeable battery. 4. The supplementary power supply of claim 1, wherein the first connector and the second connector are Universal Serial Bus connectors. 5. The supplementary power supply of claim 1, further comprising a power regulator configured to regulate the electrical power provided to the peripheral device. 6. The supplementary power supply of claim 5, wherein the power regulator causes to be provided to the peripheral device at least one of: electrical power primarily from the supplementary power supply; electrical power primarily from the host device; and a combination of electrical power from the supplementary power supply and electrical power from the host device. 7. The supplementary power supply of claim 1, further comprising a third connector configured to couple the supplementary power supply to an external power source, wherein the external power source is configured to provide electrical power that supplements the electrical power provided to the peripheral device and the external power source is further configured to recharge the first power source. 8. The supplementary power supply of claim 1, further comprising: a first cable, a first end of the first cable coupled to the first connector and a second end of the first cable coupled to the supplementary power supply; and a second cable, a first end of the second cable coupled to the second connector and a second end of the second cable coupled to the supplementary power supply, the first cable and the second cable coupled to the supplementary power supply such that electrical power and data are configured to pass between the first connector and the second connector through the first cable, the supplementary power supply, and the second cable. 9. A cable, comprising: a first portion cable; a second portion cable; a first connector on a first end of the first portion cable, the first connector coupleable to a host device; a second connector on a second end of the second portion cable, the second connector coupleable to a peripheral device; a supplementary power supply positioned between at least parts of the first and second portions of cable, the supplementary power supply electrically coupled to the second portion to provide power to the peripheral device; a first path through the first and second portions of cable to allow data to pass between the host device and the peripheral device; and a second path through the first and second portions of cable to allow electrical power to pass from the host device to the peripheral device, wherein the supplementary power supply comprises 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. 10. The cable of claim 9, wherein the electrical power provided by the supplementary power supply supplements the electrical power provided to the peripheral device by the host device. 11. The cable of claim 9, wherein the supplementary power supply includes a battery operable to provide electrical power to the peripheral device. 12. The cable of claim 9, wherein the first connector and the second connector are Universal Serial Bus connectors. 13. The cable of claim 9, further comprising a power regulator within the supplementary power supply configured to regulate the electrical power provided to the peripheral device. 14. The cable of claim 9, further comprising a third connector on the supplementary power supply configured to couple the supplementary power supply to an external power source, wherein the external power source is configured to provide electrical power that supplements the electrical power provided to the peripheral device and the external power source is further configured to recharge the supplementary power supply. 15. A method for providing electrical power to a peripheral device, comprising: connecting the peripheral device to a supplementary power supply; connecting a host device to the supplementary power supply; operating 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; and providing electrical power from the supplementary power supply to the peripheral device, the electrical power provided by the supplementary power supply supplementing electrical power provided to the peripheral device by the host device. 16. The method of claim 15, further comprising passing data between the host device and the peripheral device through the supplementary power supply. 17. The method of claim 15, further comprising providing electrical power from a battery in the supplementary power supply to the peripheral device. 18. The method of claim 15, wherein the connection of the peripheral device and the connection of the host device are accomplished using standard Universal Serial Bus connectors. 19. The method of claim 15, further comprising operating a power regulator within the supplementary power supply to regulate the electrical power provided to the peripheral device. 20. The method of claim 15, further comprising connecting a third connector on the supplementary power supply to an external power source, the external power source supplementing the electrical power provided to the peripheral device by the supplementary power supply, and the external power source recharging the supplementary power supply.
