Abstract

A variable output power supply includes a power unit comprising a housing including an output port, one or more accessories disposed in the housing, and a controller disposed in the housing and in communication with the output port. The variable output power supply also includes a power cable. The controller is operable to modify operation of the output port in response, at least in part, to insertion of the power cable in the output port.

Claims

1. A variable output power supply comprising:

a power unit comprising;

a housing including an output port;

one or more accessories disposed in the housing; and

a controller disposed in the housing and in communication with the output port; and

a power cable, wherein the controller is operable to modify operation of the output port in response, at least in part, to insertion of the power cable in the output port.

2. The variable output power supply of claim 1 wherein the one or more accessories comprise a battery.

3. The variable output power supply of claim 1 wherein the one or more accessories comprises a memory.

4. The variable output power supply of claim 1 wherein the one or more accessories comprise at least one of a WiFi hotspot, an LED projector, a speakerphone, or an internet phone.

5. The variable output power supply of claim 1 wherein insertion of the power cable in the output port is operable to modify an output voltage of the output port.

6. The variable output power supply of claim 1 wherein the output port complies with a USB standard

7. The variable output power supply of claim 1 wherein the power cable comprises a predetermined pin that is grounded.

8. The variable output power supply of claim 1 wherein the power cable comprises at least one of a voltage source or a signal source.

9. The variable output power supply of claim 1 further comprising a keyhole adjacent the output port, wherein the power cable comprises a key operable to be inserted into the keyhole.

10. The variable output power supply of claim 9 wherein the output port comprises a first output port and the keyhole is adjacent a first side of the first output port, the variable output power supply further comprising a second output port adjacent a second side of the first output port.

11. A method of operating a variable output power supply including an AC adapter and a battery, the method comprising:

setting an output voltage of an output of the variable output power supply to a default voltage;

determining a configuration of an output cable;

modifying the output voltage of the output of the variable output power supply as a function of the cable configuration; and

coupling either the AC adapter or the battery to the output of the variable output power supply.

12. The method of claim 11 wherein coupling either the AC adapter or the battery to the output of the variable output power supply comprises receiving a selection of the AC adapter or the battery.

13. The method of claim 12 wherein receiving the selection comprises receiving an input from a mobile application.

14. The method of claim 11 wherein modifying the output voltage comprises increasing the output voltage.

15. The method of claim 14 wherein increasing the output voltage comprises increasing the output voltage from 5 V to 19.5 V.

16. The method of claim 11 wherein modifying the output voltage comprises decreasing the output voltage.

17. The method of claim 11 wherein the default voltage is 5V.

18. The method of claim 11 wherein the default voltage is compliant with the USB standard.

19. The method of claim 11 wherein the battery is disposed in a housing of the variable output power supply.

20. The method of claim 11 wherein the variable output power supply comprises a first output port, a keyhole adjacent a first side of the first output port, and a second output port adjacent a second side of the first output port, wherein the output cable comprises a key operable to be inserted into the keyhole.
