Charger system and method

1. A charger able to provide power through a Universal Serial Bus (“USB”) connector comprising:

a power source interface configured to receive power;

a power converter coupled to the power source interface, the power converter configured to use the received power to generate power output;

a charging controller configured to control an amount of power provided at the USB connector on the power lines derived from the power output, and configured to generate an identification signal on the USB connector's two data lines, the identification signal usable to indicate the charger is not subject to standard USB power limitations, the identification signal provided through the use of a resistance between the D+ and D− data lines.

2. The charger of claim 1 where the identification signal comprises both data lines pulled into a high state.

3. The charger of claim 2 where the data lines are pulled into the high state using at least one resistor.

4. The charger of claim 1 further comprising a plurality of USB connectors in operable connection to the charging controller.

5. A method for providing a charge current by a charger having a Universal Serial Bus (“USB”) connector comprising:

receiving power at an interface configured to receive power;

generating a power output derived from the received power and providing the generated power at the USB connector;

providing an identification signal using the USB connector's D+ and D− data lines, the identification signal usable to indicate the charger is not subject to the standard USB power limitations, the identification signal provided through the use of a resistance between the D+ and D− data lines.

6. The method of claim 5 where the identification signal comprises both data lines pulled into a high state.

7. The method of claim 6 further comprising pulling the data lines high using at least one resistor.

8. The method of claim 5 further comprising a plurality of USB connectors, each operable to provide the identification signal.

9. A method for providing a charge current by a charger having a Universal Serial Bus (“USB”) connector comprising:

receiving, at a power source interface configured to receive power from a source other than the charger, power;

converting the received power into output power;

controlling an amount of power provided at the USB connector, the controlled amount of power derived from the output power;

enabling an identification signal on the USB connector's D+ and D− lines, the identification signal comprising D+ and D− both in a high logic state; and

providing output power to the USB connector based on at least one of voltage and current draw detectable from the power lines of the USB connector, differently than normal USB power limitations.

10. The method of claim 9 where both data lines pulled into a high state through the use of a resistance.

11. The method of claim 10 further comprising pulling the data lines high using at least one resistor.

12. A method for signaling by a charger having a Universal Serial Bus (“USB”) connector comprising:

receiving power at an interface configured to receive power;

converting the received power into output power;

providing power at the USB connector, the power derived from the power output;

providing a signal on the USB connector's two data lines, the signal comprising both D+ and D− data lines in a high state, the signal usable to indicate the charger is not subject to the standard USB power limitations.

13. The method of claim 12 where the data lines use a resistance while being pulled into a high state.

14. The method of claim 13 further comprising pulling the data lines high using at least one resistor.
