Abstract

Power adapters are disclosed. An example power adapter includes a housing. The example power adapter also includes a power converter to convert an input power to an output power. The example power adapter also includes a communication pod carried by the housing, the port to receive data from a first device. The example power adapter also includes a terminal to transfer power from the power converter to the second device, and to transmit the data received from the first device to the second device. The example power adapter also includes a communication line to communicate the data from the communication port to the terminal.

Claims

1. A power adapter, comprising:

a housing;

a power converter to convert an input power to an output power;

a communication port carried by the housing, the port to be coupled to a first device; and

a terminal to transfer power from the power converter to a second device, and to transmit data received from the first device to the second device.

2. A power adapter as defined in claim 1, further comprising a transmission line to couple the power converter to a power source.

3. A power adapter as defined in claim 1, further comprising a transmission line to couple the terminal to a power port of the second device.

4. A power adapter as defined in claim 1, further comprising a second power converter to transfer power to the first device.

5. A power adapter as defined in claim 4, further comprising a circuit to tailor the output power from the first converter to a specification of the first device.

6. A power adapter as defined in claim 1, further comprising a first wire to transfer the output power from the power converter to the second device, and further comprising a second wire to transmit the data to the second device.

7. A power adapter as defined in claim 1, wherein the communication port is to transmit data received from the second device to the first device.

8. A power adapter as defined in claim 1, further comprising a communication line to communicate the data from the communication port to the terminal.

9. A power adapter, comprising:

a Universal Serial Bus (USB) port to receive data from a first computing device;

a power converter to convert power from a power source to an output power; and

a terminal to present the output power to a second computing device in communication with the terminal via a first transmission line, the terminal to route data from the first computing device coupled to the USE port to the second computing device via the first transmission line.

10. A power adapter as defined in claim 9, wherein the terminal is to receive data from the second computing device via the first transmission line, and the terminal is to route the data received from the second computing device to the first computing device via the USB port.

11. A power adapter as defined in claim 9, wherein the first transmission line is to be coupled to a power port of the second computing device.

12. A power adapter as defined in claim 9, further comprising a second transmission line to couple the power converter to the power source, the first transmission line and the second transmission line being different.

13. A power adapter as defined in claim 9, further comprising a charger circuit to receive the output power from the power converter and to supply adjusted power to the USE port.

14. A power adapter as defined in claim 13, further comprising a limiter to restrict the supply of the adjusted power to the USE port based on a demand of the second computing device.

15. A power adapter as defined in claim 13, further comprising a customizer to tailor the adjusted power based on a profile of the first computing.

16. A method, comprising:

converting first power to second power;

transferring the second power to a first computing device in communication with a terminal of a power adapter; and

transferring data received from a second computing device from a communication port to the first computing device via the terminal.

17. A method as defined in claim 16, further comprising transferring data received from the first computing device via the terminal to the communication port.

18. A method as defined in claim 16, further comprising supplying third power to the communication port.

19. A method as defined in claim 18, further comprising limiting the third power to the communication port based on a demand of the first computing device.

20. A method as defined in claim 18, further comprising adjusting the third power based on the type of the second computing device.
