Abstract

A power adapter and a method for adapting power for electronic devices. Two or more input ports (101 103 105) are connectable to electrical power sources. An output port (109) is connectable to an electronic device. A controller (113) is in parallel power receiving communication with the input ports (101 103 105) in power providing communication with the output port (109) and in data carrying communication between the output port (109) and a first one of the input ports (101). The method includes checking for electrical power at the first input port (101) and at least one other input port (103 or 105) and when electrical power is present at both coupling the power from the input ports in parallel to the output port (109) and enabling data communication between the first input port (101) and the output port (109). The power adapter and the method enable the electronic device to draw power simultaneously from two or more sources while maintaining data communication with a host.
