Abstract
A reverse charging device includes a processor, a standard downstream port (SDP) and a first link on which a charging downstream port (CDP) interface chip is arranged. When it is detected that an adapter is plugged into the SDP, the processor is connected with the SDP through the first link, and the processor, the CDP interface chip, and the SDP form a CDP to perform reverse charging through the CDP and the adapter, wherein the CDP has a current transmission capability higher than the SDP.
