Description
The Knightsbridge CS9908BCG is a 13A 2-gang DP switched socket with two USB-A fast charge ports supporting QC2.0 and QC3.0 protocols. The dual USB-A outlets provide a combined 5V DC 4A output, with voltage switching between 5V and 12V to match the charging requirements of compatible Android devices. The brushed chrome faceplate sits over a grey insert, with double-pole switching that isolates both live and neutral lines when the socket is turned off.
Designed for commercial and residential installation in cafés, hotel rooms, offices, and tech-heavy domestic spaces, the socket delivers up to 50% charge in 30 minutes when paired with QC-compatible phones and certified cables rated for power delivery. The fast charge capability runs 80% faster than a standard 5V 2A charger, reducing the time devices need to remain plugged in. The Over Voltage Category III rating suits commercial installs where surge protection and component durability matter.
The 430 stainless steel construction provides corrosion resistance in environments with higher humidity or temperature variation than typical domestic settings. The brushed chrome finish offers a cooler metallic tone than brass or gold finishes, pairing with contemporary, industrial and minimalist interiors. The grey insert behind the faceplate creates a defined edge around each outlet aperture and hides the back of the cover plate. The socket requires a 25mm minimum back box depth and projects 15.1mm from the wall once installed, with captive terminals to simplify wiring during fitting.
The IP20 rating indicates protection against solid objects larger than 12.5mm but no protection against water ingress, so the socket is intended for dry indoor locations only. The Class I construction requires an earth connection. Knightsbridge provides a 2-year guarantee on the unit.

Product Specification Sheet
Frequently Asked
What devices are compatible with the fast charge feature?
The USB-A ports support Qualcomm Quick Charge 2.0 and 3.0 protocols, which work with compatible Android devices from manufacturers including Samsung, LG, Sony, and Motorola. iPhones do not support QC protocols and will charge at standard USB rates. Check your device specifications to confirm QC compatibility.
What back box depth is required?
A 25mm minimum back box depth is needed for safe installation. The socket projects 15.1mm from the wall once fitted, with 13.7mm recessed behind the wall surface.
Can both USB ports charge simultaneously at fast charge speeds?
The combined USB output is 5V DC 4A across both ports. When two devices are connected, the available current is shared between them. Fast charge protocols work best when a single device is connected to one port.
What's the difference between this and the standard USB socket?
Standard USB sockets provide 5V 2A output. The fast charge version supports voltage switching between 5V and 12V and delivers higher current, charging compatible devices up to 80% faster than a standard 5V 2A charger when used with certified cables rated for power delivery.
