The Knightsbridge CS7USB4BCG is a 13A 1-gang switched socket with four USB-A charging ports built into a brushed chrome square-edge faceplate with a grey insert. The socket delivers 5V DC at a total of 5.1A across the four USB ports, with one port rated at 2.1A for tablets and the remaining three sharing a 3A output for phones and smaller devices. The 13A switched outlet handles standard UK appliance loads up to 2,990W.
Designed for hospitality, coworking spaces, airport lounges, hotel rooms and reception areas where multiple users need simultaneous device charging, the socket eliminates the need for plug-in USB adapters and reduces clutter around shared power points. The square-edge plate sits flush to the wall with a raised edge and built-in gasket that provides a defined finish line against painted or tiled surfaces. The socket fits standard 25mm minimum back boxes and uses screw terminals for the mains connection.
The brushed chrome finish is 430 stainless steel with a directional grain that hides fingerprints and light scratches better than polished finishes. The grey insert behind the faceplate provides contrast against the chrome and conceals the back of the cover plate. The socket carries BS1363-2 certification and is EMC and ErP compliant, meeting UK wiring regulations for installation in domestic and commercial premises. The USB ports automatically adjust output to the connected device, but certified USB cables are required for safe charging performance.

What's the total USB charging output?
The socket provides 5V DC at a total of 5.1A across four USB-A ports. One port is rated at 2.1A for tablets, while the remaining three ports share a 3A output for phones and smaller devices. The ports automatically adjust output to the connected device.
What back box depth is required?
A 25mm minimum back box depth is needed for safe installation. The square-edge plate adds 15.7mm of projection from the wall once fitted, giving a total depth of approximately 33.8mm including the back box.
Can I charge USB-C devices?
The socket has USB-A ports only. USB-C devices can be charged using a USB-A to USB-C cable. For native USB-C charging, see the Knightsbridge models with dedicated USB-C ports in the same range.
Is the faceplate removable for redecorating?
Yes. The square-edge plate is screw-fixed to the back box and can be removed for painting or tiling around the socket. The raised edge and built-in gasket provide a clean finish line against the wall surface when refitted.
