An "extension leads board," also known as an extension board, power strip, or multi-plug adapter, is a common electrical device used to provide multiple electrical sockets from a single wall outlet. They are essential tools for powering multiple devices in homes, offices, and other settings.

Key Components:

Multiple Sockets: A single block with several outlets, allowing you to plug in more than one device at a time. The number of sockets can vary, typically from 2 to over 10.

Extension Cord: A flexible electrical cable that connects the board to the wall outlet, extending the reach of your power source. The length of the cord can range from a few feet to several meters.

Plug: The connector at the end of the cord that plugs into the wall socket.
