Dual USB-A & USB-C Charger Module 3.1A - White 25x50mm Euro Grid

The Knightsbridge dual USB charger module combines one USB-A and one USB-C port in a 25x50mm white euro-module format, delivering a shared 5V 3.1A (15.5W) output. The module fits standard euro-module grid faceplates, allowing USB charging to be integrated into custom switch and socket configurations alongside conventional power outlets, light switches and data ports.

Designed for residential, hospitality and office installation, the module suits kitchens, home offices, hotel rooms and workstations where device charging is needed without displacing existing socket capacity. The 25x50mm footprint occupies one euro-grid space, so a 2-module grid plate can hold this USB charger plus a conventional 13A socket, or a 3-module plate can combine the USB module with two switched sockets. The shared 3.1A output allows simultaneous charging of two devices, with current split between the ports according to device draw.

The white ABS construction matches standard white grid plates and provides Class II double-insulated protection. The module requires a minimum 35mm back box depth and is certified to BS 5733 and BS EN 62368. Overload protection prevents damage to connected devices if the combined draw exceeds the 3.1A rating. The USB-C port supports modern fast-charge protocols, while the USB-A retains compatibility with older cables and devices.

Product Specification Sheet

What grid faceplate system does this fit?

This is a 25x50mm euro-module that fits Knightsbridge and other compatible euro-grid faceplates. It occupies one module space, so you can combine it with other euro-modules such as sockets, switches or data ports in multi-module grid plates.

What is the shared 3.1A output?

The module delivers a total of 5V DC at 3.1A (15.5W) across both ports combined. If you charge one device, it can draw up to 3.1A. If you charge two devices simultaneously, the available current is split between them according to their individual draw, with the total never exceeding 3.1A.

What back box depth is required?

A minimum 35mm back box depth is needed to accommodate the 36.5mm module depth and allow safe installation clearance. Standard 35mm single or double back boxes are suitable.

Does it work with iPad and iPhone fast charging?

The USB-C port supports modern charging protocols including USB Power Delivery, which works with recent iPhones and iPads. The USB-A port provides standard 5V charging for older devices. Check your device specifications to confirm compatibility with 5V charging.
