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.\u003c\/p\u003e\n\u003cp\u003eDesigned 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e87.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e147.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e30.3mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e9.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e20.8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.
