SYSTEM AND METHOD FOR CHARGING A BATTERY IN A MOBILE DEVICE
First Claim
1. A Universal Serial Bus (“
- USB”
) adapter for providing power through a USB connector, the USB connector configured to be connectable to a USB-equipped mobile device, comprising;
a plug unit configured to receive energy from a power socket;
a power converter coupled to the plug unit, the power converter being configured to regulate the received energy from the power socket to generate a power output;
an identification subsystem configured to generate an identification signal, the identification signal configured to indicate the USB adapter is configured to send substantial energy through the USB connector without requiring device enumeration; and
where the USB connector is coupled to the power converter and the identification subsystem, the USB connector configured to be able to send the power output and the identification signal.

Abstract
An adapter for providing a source of power to a mobile device through an industry standard port is provided. In accordance with one aspect of the invention, the adapter comprises a plug unit, a power converter, a primary connector, and an identification subsystem. The plug unit is operative to couple the adapter to a power socket and operative to receive energy from the power socket. The power converter is electrically coupled to the plug unit and is operable to regulate the received energy from the power socket and to output a power requirement to the mobile device. The primary connector is electrically coupled to the power converter and is operative to couple to the mobile device and to deliver the outputted power requirement to the mobile device. The identification subsystem is electrically coupled to the primary connector and is operative to provide an identification signal.
