3M 4 USB extension lead 13A 3250W
Product description
A compact power extension lead that helps you run everyday desk and bedside devices without hunting for extra sockets. This 3M 4 way multi plug extension cable includes AC outlets alongside four USB ports, so you can power devices and charge phones, tablets and accessories from one tidy setup. It is rated up to 13A, with a maximum total output of 3250W, according to the manufacturer, giving you headroom for typical home and office use. ✅
Key points

If your workspace is short on power points, this 3M extension lead is designed to make charging and plugging in simpler at home or in a hotel room. The compact size helps it suit tight spaces, while the four USB slots let you connect multiple charging leads at the same time. You also get AC plug extension for multiple 2 pin devices, including items such as an electric toothbrush charger or an electric shaver, using a compatible UK 2 pin shaver style plug.


The 4 way layout is built for practical everyday use. With a 1.5m extension cable length, you can position the lead where you need it on a desk, bedside table or in a living room, without keeping cables under tension. The four sided design is meant to apply uniform force and, combined with anti slip strips at the base, it is intended to stay put during normal use.

It also includes safety features intended to reduce common risks when charging. There is circuit overload protection and short circuit protection, and it is also described as having fire protection, so you can use it with more confidence while your devices are connected. The child lock feature adds an extra layer of protection around the socket area, which can be useful in busy households with children. 😊
Worth noting, as with any extension lead, the combined load should not exceed the maximum total output of 3250W, according to the manufacturer. If you connect high power appliances, it is best to consider the overall rating and your device requirements before powering everything at once.

What stands out


The standout feature here is combining AC extension with multi USB charging in one compact unit. With 4 USB ports in addition to AC sockets, you can keep your desk organised by charging multiple devices without needing a separate USB charger brick. The manufacturer specifies different USB output capabilities across the ports, with three USB A slots and one USB C slot, so you can match your cables to what you have.

It also includes a plug extension arrangement that supports multiple AC outlets plus a 2 pin electric toothbrush or shaver device connection. That makes it convenient for morning routines, where your grooming charger may otherwise compete for space and outlet access. For workplaces and home stations, it is easy to see the benefit when you want to power a laptop charger at the socket level while also topping up a phone or earbuds case via USB.
Safety and build details help it fit real day to day situations. The lead is described as certified by UKCA and RoHS, and it includes multiple safety protections such as overload protection and short circuit protection. There is also a child lock, and the base is equipped with two anti slip strips to help with fixation so the lead is less likely to tip over during use.

It is a solid choice if you need a compact extension lead for desktop and bedside use, especially when you want USB charging integrated with extra UK sockets. You may want to skip it if you require longer cable reach, since the extension length is 1.5m as specified.
