13A 1 Gang Switched Socket with Quad USB Charger - Polished Chrome Screwless (Grey Insert)

The Knightsbridge SFR7USB4PCG is a 13A 1-gang switched socket with four integrated USB charging ports behind a polished chrome screwless faceplate with a grey insert. 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.

Designed 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.

The 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.

The 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.

Product Specification Sheet

What back box depth is required?

A 25mm minimum back box depth is needed for standard wiring configurations. More complex wiring runs (multiple cables, deep terminals) may require 30-35mm depth to accommodate the socket terminals and USB module without forcing cables.

Can all four USB ports be used simultaneously?

Yes. The total output is 5.1A across all four ports: one port delivers up to 2.1A for tablets, while the remaining three share 3.0A (1A each). Plugging four devices in simultaneously will charge all four, with the ports automatically distributing power according to device draw.

Is the screwless plate removable for redecorating?

Yes. The polished chrome cover plate clips onto a separate metal sub-frame fixed to the back box. The cover can be removed for painting around the socket and re-clipped without re-wiring or disturbing the electrical connections.

What other finishes are available in this range?

Knightsbridge produces this quad USB socket in multiple finishes including brushed chrome, matt black, polished brass, antique brass and white. Use the search function or filters to find other variants in stock at Niori.
