3M 3-Way Extension Lead with 4 USB (2 USB-A + 2 USB-C) and 3m Cable for Home Office
Product description
The essentials
If your desk is always short on sockets, this 3M extension lead is designed to tackle that in one go: it combines three AC outlets with four USB ports (2 USB-A and 2 USB-C). On paper it’s aimed at the kind of everyday setup where you’ve got a laptop docking station, a phone, a tablet and maybe a lamp or monitor—all needing power nearby.
It also includes a switch at the bottom, which is a practical touch if you often power things on and off together. The compact design is meant to work in tighter spaces, while the 3m cable gives you a bit of reach for typical home office or living-room layouts.
What it’s for (and what it helps you avoid)

This extension lead is meant for desktop and near-desk use: charging and powering devices in the same spot without constantly swapping adapters. A common pain point with USB charging is ending up with extra power bricks cluttering the desk, with built-in USB-A and USB-C, you can simplify the setup.
A quick example: imagine placing the lead under or behind your desk, then plugging in a monitor and a small desk lamp to the AC outlets. Your phone can take one USB-A port, while your tablet or another device can use a USB-C port. When you’re done for the day, you can switch off the ports together rather than hunting for multiple switches.
Key features that matter in daily use
The standout promise here is “7-in-1” functionality: three AC outlets plus four USB charging ports. The USB ports are rated (5V/2.4A for USB-A slots and 5V/3A or 5V/3A for USB-C slots, plus an overall USB output figure of 5V/3.4A as stated), so you’re not just getting extra ports—you’re getting a defined charging layout.



There’s also a switch built into the extension. That can be genuinely useful if you regularly leave devices connected but don’t want them drawing power when you’re not using them. It’s not a magic energy saver on its own, but it does make “off” simpler.
On the physical side, the lead is described as compact (listed dimensions are 6.5 x 6.5 x 6.6 cm) and includes anti-slip strips at the base to help it stay put and reduce tipping while in use.

Where it shines, and where it may not be the best fit
This is a solid match if you want fewer wall adapters and a neat charging spot for a home office, nightstand, bedroom or living area. The 3m cable length is also enough for typical room layouts (for example, getting around the back of furniture), and the compact body can help where a bulky multi-socket would look out of place.
It may not be ideal if you expect to run heavy loads through the AC outlets. The extension is capped at a maximum total output of 3000W/13A, so high-wattage equipment needs careful consideration. Also, if you’re planning to use it outdoors or in a harsh environment, you’ll still need to follow whatever safety guidance applies to your specific setting—this description focuses on home use.



Compatibility & requirements to keep in mind
This product is designed around UK household mains use, and it’s specifically described as a 3m extension lead with UKCA certification. For USB charging, it supports devices that accept USB charging through USB-A or USB-C connections, but charging speed will still depend on what your device supports (the lead provides the stated port outputs, not a guaranteed charging profile for every gadget).
Also keep in mind that the switch can turn off multiple devices at once, which is convenient for daily routines — but if you need certain equipment to remain powered continuously, you’ll want to think about how you’ll use that on/off behaviour.
Is it worth it?

It’s worth considering if you want one desk-focused power solution: three AC outlets for your essentials, plus USB-A and USB-C for charging phones, tablets and other everyday devices. The switch, anti-slip base and child lock are the kind of details that make a difference over time, especially in busy households.
You may want to skip it if you’re planning to power high-wattage appliances from the AC outlets, or if you prefer having independent control over each socket rather than switching everything together.
