Mscien 2m Extension Lead with USB Slots – 4-way 3 USB extension socket with wall mounting
Product description
What it is and why people buy it
This Mscien extension lead is designed for the everyday problem of “too few sockets, too many devices”. It combines a 4-way extension socket with dedicated USB charging ports, plus a 2m cable and an on/off switch. The idea is simple: plug in mains-powered items where you need them, and use the built-in USB ports for phones, tablets, and similar gadgets so you don’t have to hunt for extra chargers.
On paper, it’s positioned as a practical multi-plug charging station for places like a home desk, office setup, and student accommodation. The wall-mountable design also hints at a more permanent installation rather than leaving a strip dangling behind furniture.
The essentials at a glance

You’re getting a multi-plug extension lead with: - Four mains outlets plus built-in USB charging (2× USB-A and 1× USB-C) - A 2m extension cord for more reach without having to run an entirely new cable - Individually switched control (so you can save power by turning off usage rather than relying on everything being live) - A wall-mount option using screw fixation on both ends
The mains side is rated up to a maximum capacity of 3250W. There’s also mention of a UK standard UK plug with a 13A fuse in the plug head, and the lead is said to use 750°C flame-retardant material.
What you’ll notice day to day
The USB functionality is the real convenience here. The lead uses “smart IC charging” to detect connected devices and provide an optimal current. In practice, that means you can plug in a mix of USB-A devices and USB-C devices (depending on what you’re charging) and expect it to behave like a normal charger rather than forcing everything into one output mode.



A small but important detail: the USB-C port is explicitly noted as not supporting devices like MacBook / MacBook Air or other devices that require 14–22V charging voltage. So while it covers everyday USB-C phones and tablets in many setups, it’s not meant to replace higher-voltage laptop charging.
For a micro example: imagine working at a desk with a laptop dock using one mains outlet, a monitor on another, and a phone on the bedside. With this lead, you can keep the desk tidy—one mains lead for power, and the phone/tablet directly into USB ports.
Strengths and where it may fall short
Strengths

- Built-in USB ports reduce clutter: fewer plug adapters and chargers fighting for space.
- Wall-mountable design helps if you want a more controlled setup (desk edge, cupboard side, or near a bedside).
- Switch control and an on/off switch that shows status can make daily use feel more intentional.
- Safety elements are specifically mentioned: child-protective safety door, plus flame-retardant material and BS1363/A compliance (as stated).
Limitations to bear in mind
- If you’re trying to charge a laptop that needs higher-voltage USB-C (14–22V mentioned), the USB-C port is not positioned for that use.
- The headline “up to 7 devices” is based on combining mains outlets and USB ports, but real-world comfort depends on what you plug in (bulky adapters can sometimes interfere with spacing, and heavy loads still need consideration). For high-power appliances, it’s worth checking your usage rather than assuming the maximum applies to all scenarios.

Who it suits (and who should avoid it)
It’s a good fit if you want one neat extension solution for a desk, dorm-style room, office, or home corner where phones and tablets are always nearby. It also makes sense if you’d rather mount the lead than leave it trailing and if you like the idea of switching the strip on and off with status visibility.
It may not be the best choice if your goal is to use the USB-C port to power laptops that require higher charging voltage (the listing specifically warns against devices needing 14–22V charging voltage). And if you regularly run very power-hungry appliances, you’ll want to be cautious and keep an eye on total load rather than relying on the headline rating.

Mini FAQ
What devices can I charge with the USB ports?
The lead includes 2× USB-A and 1× USB-C. The USB-C port is stated as not supporting MacBook/MacBook Air or devices needing 14–22V charging voltage, so it’s best for typical USB-charged gadgets rather than higher-voltage laptop charging.
Is it safe for household use?



The product info mentions BS1363/A compliance, a 13A fuse in the plug head, child-protective safety doors, and flame-retardant material. As with any extension lead, you still need to use it within the stated limits.
Can it be mounted on a wall?
Yes—there’s a screw fixation design on both ends, intended for wall or desk mounting (as stated).
How long is the cable?
The extension cord is 2m.
Is it good for a bedside charging setup?
Yes, that’s one of the suggested use cases. The mix of mains outlets and USB charging makes it practical for charging phones while powering a lamp, radio, or other small electronics.
Final verdict
It makes sense if you want a single 2m extension lead with USB charging built in, plus individual switching and the option to wall-mount it. That combination is especially handy in student rooms, home offices, and anywhere you’re trying to reduce charger clutter.
Just don’t treat the USB-C as a universal laptop charger—if you need 14–22V charging voltage, the listing is clear that this isn’t meant for that.
