The USB section delivers 5.1A total output: one dedicated 2.1A port for tablets and three ports sharing 3.0A (1A each) for smartphones and smaller devices. The 13A socket itself is independently switched, allowing the mains outlet to be isolated while USB charging continues.\u003c\/p\u003e\n\u003cp\u003eDesigned for hospitality, office and residential installation where multiple devices need simultaneous charging, the socket suits hotel rooms, café seating areas, office desks, kitchen worktops and bedside positions. The quad USB configuration means fewer individual chargers competing for wall space, and the faceplate's screwless design removes visible fixings for a cleaner finish. The socket fits a 25mm back box in standard wiring conditions, though more complex runs may require 30-35mm depth.\u003c\/p\u003e\n\u003cp\u003eThe polished chrome finish is achieved through electroplating onto a 201 stainless steel faceplate, giving a high-gloss reflective surface that pairs with traditional, contemporary and transitional interiors. The grey insert behind the faceplate hides the back of the cover plate and provides a neutral contrast to the chrome surround. The screwless cover clips onto a separate metal sub-frame, meaning it can be removed for redecorating without disturbing the wiring. The socket meets BS1363-2 and is EMC compliant and ErP Ready.\u003c\/p\u003e\n\u003cp\u003eThe faceplate measures 147.5mm wide by 87.5mm tall with a 9.5mm projection from the wall once fitted. The built-in gasket seals the edge of the faceplate to the wall, reducing dust ingress and giving a tighter visual fit than ungasketed plates. USB output is rated at 5V DC up to 5100mA total across all four ports, and certified USB cables are recommended for full power delivery to devices.\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.
