Premium Brushed Steel 13A Socket with 18W USB-A & USB-C Fast Charging

The BG Nexus Metal NBS21UAC18G combines a traditional 13A single switched socket with integrated USB-A and USB-C fast charging, providing mains power and convenient device charging from one stylish wiring accessory.

Finished in premium brushed steel with grey inserts, the socket features a slim profile with softly rounded edges for a clean, contemporary appearance. The integrated USB charger delivers up to 18W variable-voltage fast charging and supports popular PD and QC charging protocols, making it ideal for smartphones, tablets and other compatible USB-powered devices.

Designed with both installers and end users in mind, the NBS21UAC18G features angled colour-coded terminals, backed-out captive screws, twin earth terminals and a moisture-control gasket.

*Charging performance depends on the connected device, cable, charging protocol and operating conditions. BG markets the unit as capable of delivering 50% charge in approximately 30 minutes and charging up to 70% faster than standard 5V charging with compatible devices.

13A Socket & USB Charging in One

The NBS21UAC18G eliminates the need to choose between using a mains socket and plugging in a separate USB charger.

The conventional 13A UK socket remains available for an electrical appliance, while the integrated USB-A and USB-C ports can be used for charging compatible mobile devices.

This makes it particularly useful beside beds, desks, kitchen worktops and other locations where USB charging is regularly required.

18W Variable-Voltage Fast Charging

Unlike basic USB sockets that provide only conventional 5V charging, the NBS21UAC18G incorporates an 18W variable-voltage fast charger.

BG specifies USB output options of 5V/3A, 9V/2A and 12V/1.5A, allowing the charger to negotiate an appropriate output with compatible devices.

This means supported smartphones and other devices can charge considerably faster than they would from a basic low-power USB outlet.

USB-C Power Delivery & Quick Charge Support

The USB-C outlet supports a range of charging protocols including PD 3.0 and QC 3.0, while additional compatibility includes Apple 2.4A, Samsung AFC, Huawei FCP and other supported charging standards.

The USB-A connection also supports QC 3.0 and several additional fast-charging protocols.

This broad protocol compatibility makes the socket suitable for charging a wide range of modern Android and Apple devices without requiring a separate plug-in charger.

USB-A & USB-C Connections

Providing both connection formats increases compatibility with existing and newer charging cables.

The socket includes:

• 1 x USB Type-A Port
• 1 x USB Type-C Port

Smart AutoDetect USB Charging

The integrated Smart USB system automatically detects the connected device and adjusts the charging pattern accordingly.

This helps provide an appropriate charging output without requiring the user to manually select a voltage or charging mode.

The system also incorporates a protective overload function and enters standby mode when the connected device is fully charged.

Up to 50% Charge in 30 Minutes

With a compatible fast-charging smartphone and suitable cable, BG states that the 18W USB system can provide up to 50% charge in approximately 30 minutes.

This makes the socket especially convenient for bedrooms, home offices, kitchens, hotel rooms and other locations where users may need to quickly top up a device.

Premium Brushed Steel Finish

Part of the BG Nexus Metal range, the NBS21UAC18G features a premium brushed steel faceplate with grey inserts.

Its softly rounded edges and slim metal profile provide a more refined appearance than conventional moulded white accessories, making it particularly suitable for contemporary residential and commercial interiors.

The brushed finish coordinates well with stainless-steel appliances, metallic light fittings, door furniture and other modern interior finishes.

Moisture-Control Gasket

A moisture-control gasket is incorporated into the socket design.

This helps prevent moisture from newly plastered walls reaching the decorative plate and causing premature tarnishing, making the accessory particularly useful during renovations and new-build finishing work.

Installer-Friendly Angled Terminals

BG has designed the rear terminals to simplify installation.

The NBS21UAC18G incorporates angled, colour-coded terminals, helping installers identify connections and access terminal screws more easily. The screws are also supplied backed out and captive, reducing the chance of them being lost during installation.

The line and neutral terminals accept 3 x 2.5mm², 3 x 4mm² or 2 x 6mm² conductors.

Twin Earth Terminals

The socket incorporates two earth terminals, providing additional flexibility during installation.

Twin earth terminals can be useful for appropriate high-integrity earthing arrangements and commercial installations, subject to the requirements of the electrical design.

Only 25mm Minimum Back Box Depth

Despite incorporating both USB-A and USB-C fast-charging electronics, the NBS21UAC18G requires a minimum mounting box depth of just 25mm.

This makes it particularly attractive for retrofit applications where an existing conventional single socket is being upgraded and a deeper back box may be difficult to install.

Actual installation space should always take account of cable quantity, conductor size and available wiring space behind the accessory.

86mm x 86mm Single-Gang Format

The NBS21UAC18G uses a standard 86mm x 86mm single-gang format, making it suitable for conventional UK single-gang accessory positions.

The overall product depth is approximately 30mm, with fixing centres of 60.3mm.

Why Choose the BG Nexus Metal NBS21UAC18G?

The BG Nexus Metal NBS21UAC18G provides a practical upgrade over a conventional single socket by adding modern USB-A and USB-C fast charging without sacrificing the 13A mains outlet.

Its 18W variable-voltage charger supports PD and QC protocols for compatible devices, while Smart USB AutoDetect automatically adjusts the charging pattern to suit the connected equipment. Protective overload functionality and standby operation when charging is complete provide additional convenience.

Installation has also been carefully considered. Angled colour-coded terminals, captive screws, twin earth terminals and a minimum 25mm mounting depth help make the accessory suitable for both new installations and upgrades to existing socket positions.

Combined with the premium brushed steel finish, grey inserts and softly rounded Nexus Metal profile, the NBS21UAC18G is an excellent choice for modern homes and commercial interiors requiring convenient USB charging alongside a traditional 13A socket.
