Hulker Cube extension lead 3m, 13A 3250W
Product description
A Hulker Cube Extension Lead gives you a tidy way to add extra sockets and USB charging where you need them, without relying on messy multi plug setups. With a 3 metre extension cable length, it helps reach those harder to access wall points in a home, dorm, office, garage, workshop or exhibition space. You can run everyday appliances and charge devices at the same time, thanks to the built in 4 AC outlets and 3 USB ports.
If you regularly plug in multiple items, a compact power strip style design can make a noticeable difference to desk and countertop clutter. This model also includes a one touch master switch, so you can turn power on and off for everything connected in one go. It uses UK fused plug design and is rated for up to 13A and 3250W total output, so you can match it to typical household loads while keeping safety protections in mind. 🧩

The essentials


The Hulker Cube Extension Lead is a 3 m extension lead with a compact cube form factor, designed to keep multiple connections organised. It combines 4 AC outlets with 3 USB ports, allowing up to 7 devices to be powered simultaneously. This is useful when you need both plug in power for devices like microwaves or hair dryers, and USB charging for mobiles, tablets and other accessories.

The power switch is positioned on top as a master ON/OFF switch, so you can control all outlets and USB ports together. That makes it practical for everyday use when you want a simple way to cut power to connected devices. 🖤 The cube design also aims to avoid plug blocking by positioning sockets on different sides, which helps when adapters make outlets harder to access.
Key features



There are a few features that matter most for day to day convenience, starting with the extension length. The 3 metre lead gives flexible reach for sockets that are far away or hard to reach, such as behind a desk, near a bedside area, or in a garage or workshop setup.
For the connection side, the combination of 4 AC outlets and 3 USB ports lets you power and charge at once, reducing the need for multiple chargers and splitters. The ON/OFF master switch simplifies control, so you do not have to unplug things individually when switching between work and rest. ✅

It is built with safety protection systems that include child safety shutters and multiple protection measures such as overload, over current, over voltage and short circuit protection, which are designed to help reduce overheating risk and protect connected devices. Please note that the total combined load should not exceed 3250W, since that rating covers the full output across connected sockets.


The design is also meant to look neat in busy spaces. With a compact size of 83 × 83 × 87 mm, it can sit on desks or countertops without taking over the area. There are also two mounting holes on the base for convenient wall or desk installation if you prefer a more fixed setup. 😊

Who it’s for
It makes sense if you want a compact extension lead that covers both standard plug in power and USB charging in one unit. You will likely appreciate it in a dorm or home office where multiple devices sit close together and you want fewer cables across the desk. It also suits garages, workshops and exhibition spaces where access to wall sockets can be limited and you need practical reach. ⚙️
You may want to skip it if your planned appliances together would exceed the 3250W total output, since the rating applies across all connected devices. It is also worth considering placement and cable routing, particularly if you are trying to keep a very clean layout around a tight workspace. When you match your load to the rating and make good use of the cube design, it can be a straightforward everyday power solution.
