Cube Kemelo 4-Way Extension Lead with 4 USB Slots (13A/3250W), 1.5m black travel power socket
Product description
If you’re often juggling a laptop, phone, and the usual “things that need charging”, this Kemelo Cube extension lead is designed for exactly that kind of chaos. It combines a 4-way plug extension with built-in USB charging slots, wrapped in a compact cube-style body that’s easy to pack.
That said, it’s not perfect for every setup: it’s a multi-socket lead aimed at everyday use, so if you need something for heavy appliances or complicated power layouts, you’ll want to check your specific device needs first.
The essentials
This is a 1.5m UK desktop-style extension lead with 4 USB slots (three USB-A ports and one USB-C port) plus plug sockets. On paper, it’s the kind of gadget that makes a single point on your desk or bedside table handle charging and small powered devices at the same time, instead of you hunting for different chargers and adapters.
The USB charging is rated at 5V, with USB-A ports at 5V/2.4A and the USB-C port at 5V/3.1A. That’s useful if you have a mix of phones/tablets and USB-C devices and want the convenience of fewer wall bricks.
There’s also a child safety lock and multi-layer protection information included (UKCA and RoHS mentioned), plus a flame-retardant housing rated 750°C V0 PC. It’s reassuring on the safety side, particularly if you’re using it in a home with children.
Where it stands out in daily use
The best reason to consider this extension lead is how it simplifies power for real life.
Picture a small university desk or a hotel room: you’ve got a laptop charger, a phone, maybe a tablet, and perhaps a grooming device. The lead is described as a 4-way setup with additional USB charging, so you can plug in AC devices and still top up devices directly from the lead.
It’s also described as having anti-slip strips to help it stay put on a smooth tabletop. That little detail matters more than you might expect when the cable is in use and you’re moving around the desk.
Finally, the compact “small square” design is pitched as travel-friendly. If you routinely take chargers with you, you’ll probably appreciate that it’s meant to pack neatly.
Key takeaways on power and safety
The total output is stated as 3250W/13A, covering the multi-plug output and the intended use for AC devices. That figure is the one to keep in mind when deciding whether your equipment is within safe expectations.
Also worth noting: there’s mention of an “Electric Toothbrush AC” plug arrangement, described as a smart multi-plug setup. In plain terms, this is about making a typical bedside or bathroom-style routine more convenient. Just be aware that if your main use is powering higher-draw appliances, you’ll want to be cautious and confirm what your device actually requires.
On safety, the lead is described as UKCA and RoHS certified, with overload protection mentioned and a child lock built in. If you’re placing it where children can reach, this is one of the stronger points here.

Who it’s for (and who should be cautious)
It makes sense if you want one compact lead for a desk, bedside area, dorm room, office, or when you’re travelling between places like hotels and flats. It’s particularly appealing if you have multiple USB devices to charge and you’d rather avoid carrying separate USB chargers.
You may want to skip it if your setup needs longer cable reach than 1.5m, or if you’re planning to run higher-power appliances where the 13A/3250W total rating becomes a genuine constraint. Also, if your “smart multi-plug” needs don’t match the way you organise your devices, you might find a simpler, more straightforward extension lead better.
Is it worth it?
Worth considering if you like the idea of turning one socket into both plug access and USB charging, especially for everyday spaces and travel. The compact design, child safety lock, and the stated overload protection are the main reasons it feels practical rather than just convenient.
It might not be the best match if your use case is mainly about powering demanding appliances, or if you need more cable length than 1.5m. In that scenario, you’ll likely want to prioritise a lead designed for that sort of load and spacing.
