What Does Power Strip Mean?

A power strip is an electrical device that is used to expand the capacity of a wall outlet in terms of the number of devices it can accommodate.

Techopedia Explains Power Strip

A power strip is a block of electrical sockets that provides additional cord length and mobility to otherwise immovable wall sockets that are oftentimes placed in obscure and hard-to-reach places. Power strips are often used in areas of the house with a large concentration of appliances, such as the living room because there are so few wall sockets.
