Extension Lead with 3 USB Slots (30W) and 4-Way Sockets, 3M Wall-Mountable Surge Protected Power Strip
Product description
What it is and what it solves
This is a 7-in-1 multi plug extension designed to expand a single wall socket into multiple outlets. It provides 4 AC outlets and 3 USB ports, letting you power phones, tablets, laptops and other devices from a single location. With a total output of up to 3000W/13A, it’s aimed at homes, offices or study spaces where socket access is limited.
How it performs on paper

On the USB front, you get two USB-C ports (30W max) and one USB-A port (12W). When all ports are in use, the combined output tops at 30W, which supports reasonably fast charging for a range of devices. The unit uses a 3M extension cord and features a fire-resistant casing, a 13A fuse, and child-safe shutters for added safety.
What stands out in daily use


Each outlet has its own switch, so you can cut power to any plug individually. The design also spaces outlets generously (5.2 cm apart) to accommodate larger adapters without crowding neighbouring sockets. There are mounting holes for wall or bench mounting and four anti-slip feet to keep the unit stable on desks or floors.

What you’ll notice day to day
The independent switches help with energy control and can reduce standby draw. The wall-mount option and compact footprint can tidy up a cluttered setup, whether in a living room, dorm, or workspace. It isn’t a universal charger, but it does consolidate a handful of devices in one convenient hub.
Who it’s for

If you’re dealing with a limited number of wall sockets but need to run multiple devices—phones, tablets, a laptop, a set of headphones or a monitor—this extension lead can be a practical helper. It’s suited to home offices, classrooms, study nooks and shared desks where wiring needs to stay organised.


Limitations and caveats
It may not be the best option if you require very high‑demand charging across many devices at once, or if USB-C Power Delivery loads exceed what the 30W total can sustain. Also, while the 5.2 cm outlet spacing helps with bulky plugs, very large adapters could still crowd adjacent sockets in tight setups.

What to check before buying
- Confirm you have enough wall or bench space to accommodate a 3M cord and the 4‑way socket block.
- Check the placement of mounting points and ensure there’s a suitable location to fix it if you plan to wall-mount.
- Consider whether USB-C PD30W and the USB-A 12W cover your typical charging needs for your devices.
Practical usage example



Imagine a study desk with a laptop, tablet, a wireless headset and a phone. You can use the four outlets for power bricks and the USB ports for charging the tablet and phone, while a separate switch controls the laptop’s energy path when not in use.
Decision section
Is it worth it?

It’s worth considering if you need to expand a single socket into multiple outputs with controlled power to each port and some built‑in USB charging. If you prioritise modular control, decent outlet spacing and a wall‑mount option in a compact 3M cord format, this model offers practicality for everyday environments. If your charging needs involve higher USB‑C PD loads or you require more than 30W total USB output, you may want to explore other options.
