- "Don't look at me. I'm an interpreter, I'm not supposed to know a power socket from a computer terminal."
- ―C-3PO to R2-D2
A power socket 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.
