Abstract
A power adapter is disclosed herein. The power adapter includes an AC-DC converter, at least one output port, at least one DC transmission cable and at least one connector. The AC-DC converter is configured to convert an input AC voltage to an intermediate DC voltage. The output port is configured to output the intermediate DC voltage. A second terminal of the DC transmission cable is connected to the output port and configured to receive and transmit the intermediate DC voltage. The connector is connected to a first terminal of the DC transmission cable and configured to output an output voltage. The connector includes a first housing, a DC-DC converter and an output terminal. The DC-DC converter is enclosed in the first housing and configured to convert the intermediate DC voltage to the output voltage. The output terminal is enclosed in the first housing and configured to transmit the output voltage.
