Power socket

A power socket, also known as a power port, was a device that allowed a piece of technology to connect to a power source. While hastening to leave Cloud City, R2-D2 mistook a power socket for a computer terminal while attempting to override the city's security systems. The little astromech droid nearly fried himself in the process, but Chewbacca came to his rescue by disconnecting him from the socket.
