Abstract
A power conversion device is configured to convert power-over-Ethernet (PoE) power to universal serial bus (USB) power to yield a USB charging port. The conversion device can conform to a number of modular and/or portable form factors, allowing existing Ethernet data ports to be easily converted to USB charging ports. The conversion device receives PoE power from the Ethernet network, converts the PoE power to an appropriate USB standard, and delivers the power to an integrated USB charging port. The conversion device can identify the charging capabilities of a portable device plugged into the USB charging port and set a maximum charging current based on the rated charging current of the portable device. In some embodiments, the conversion device can be incorporated in an apparatus that also facilitates data transfer via the USB port.
