The socket provides a single 13A outlet for mains appliances, while the USB array delivers a shared 5V DC 5.1A output split across four ports: one dedicated 2.1A port for tablets or high-draw devices, and three ports sharing 3A for phones, earbuds and smaller accessories.\u003c\/p\u003e\n\u003cp\u003eDesigned for bedrooms, hotel rooms, co-working desks and kitchen worktops where multiple devices need charging without occupying the mains outlet, the quad USB layout allows four simultaneous connections while the 13A socket remains available for a kettle, lamp or laptop charger. The screwless cover plate clips onto a separate metal sub-frame, hiding all fixings once installed and giving a cleaner wall finish than screw-fixed alternatives.\u003c\/p\u003e\n\u003cp\u003eThe 201 stainless steel faceplate is finished in polished brass with a protective lacquer that resists tarnishing under normal indoor use. The black insert behind the brass plate defines each outlet aperture and hides the back of the cover. The socket is BS1363-2 certified and EMC\/ErP compliant, and includes a gasket for secure flush mounting against plasterboard or masonry. A 25-35mm minimum back box depth is required depending on cable entry and termination space.\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.
