The dual USB configuration delivers up to 18W when a single port is in use, or 20W shared (5V DC, 4.0A total) when both ports charge simultaneously. The single-pole switch isolates the live conductor when off, suitable for standard residential loads up to 2,990W.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential, office and hospitality installation, the socket fits a 35mm minimum back box depth and uses a screwless cover plate that clips onto a separate steel sub-frame. The USB-C port supports PD (Power Delivery) and QC (Quick Charge) protocols, allowing compatible smartphones and tablets to reach 0-50% charge in approximately 30 minutes. Adaptive charging automatically adjusts voltage to match each connected device, and built-in overload, overheat and over-current protection prevents damage to both the socket and connected equipment.\u003c\/p\u003e\n\u003cp\u003eThe matt black finish provides a low-sheen surface that minimises fingerprint visibility and pairs cleanly with contemporary, industrial and monochrome interiors. The black insert behind the faceplate hides the back of the cover plate and gives a defined edge to each outlet and USB aperture. The socket carries Over Voltage Category III approval for use in fixed installations and draws 0.1W on standby. A 10mm spacer is included for mounting flexibility in back boxes of varying depth.\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\u003e87.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e87.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e4.3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.
