These built-in sockets can be raised up or recessed within a desk or tabletop, creating a cleaner, neater workspace. In the ejected state, the socket offers USB charging and electricity. In the closed state, the cords disappear and the environment looks tidy and uncluttered. The bottom of the socket is also equipped with multiple jacks for plugging in a computer or other devices. A stationary device on a tabletop can get power from the lower jack through the cable hole, another feature that keeps the desktop neat and clean.
