🔌 is an emoji of a power plug. It represents a power plug or socket and is usually used to express concepts related to electricity, charging, and electrical appliances being connected to a power source. For example, when you want to indicate that a certain device needs to be charged, you can use this emoji; or it can also be used when discussing the installation of electrical appliances, which involves the connection between the plug and the socket.
