13A 1 Gang Switched Socket Quad USB 5.1A - Brushed Chrome Screwless (Grey Insert)

The Knightsbridge 13A 1-gang switched socket integrates four USB-A charging ports behind a brushed chrome screwless faceplate with a grey insert. The USB ports share a 5.1A output at 5V DC, with one port delivering up to 2.1A for tablets and the remaining three sharing a 3A allocation across phones and smaller devices.

Designed for receptions, cafés, co-working spaces and residential bedside or desk installations, the socket provides mains power and multi-device USB charging from a single wall plate. The 13A switched outlet handles standard UK appliance loads up to 2,990W, while the four USB ports eliminate the need for separate plug-in chargers. The screwless cover plate clips onto a metal sub-frame fixed to the back box, hiding all fixings behind the wall-facing faceplate.

The brushed chrome finish is formed from 201 stainless steel with a horizontal brushed grain that resists fingerprints and pairs with both contemporary and traditional interiors. The grey insert behind the faceplate defines the socket aperture and USB port openings cleanly without a stark black contrast. A built-in gasket provides a flush seal against the wall, reducing dust ingress behind the plate. The socket requires a 25-35mm back box depth depending on wiring conditions and carries BS1363-2 certification plus EMC and ErP compliance.
