A DC Connector is an electrical connector for supplying direct current (DC) power. Compared to domestic AC power plugs and sockets, DC connectors have many more standard types that are not interchangeable. Stranded wire is good for both. It can be a concentric plug/socket (although these Often Used For AC) or a Jones plug/socket, the cigar lighter for a car, etc, etc. It is not a complex task and can be completed quickly and painlessly. DC Connector is made for use in the various places.
