Cube Extension Lead with USB Slots: 4-Way Tower Power Strip with 6 USB Ports

What it is and what problem it solves

This is a cube-shaped tower extension lead designed to maximise desk space by mounting four AC outlets on four faces, freeing surface area for your workspace. It combines four independent switches with eight USB ports (3 USB-C and 3 USB-A on the device itself, plus the 4 AC sockets) to cater to a typical home office, student dorm, or compact desk setup where outlets are at a premium. The 1.5 m extension cord gives you flexibility in positioning, while the vertical layout helps you keep cables organised and out of the way.

How it’s laid out and what stands out

Unlike traditional flat power strips, this tower design uses a multi-surface arrangement to avoid blocking nearby sockets. The device includes four switches, one on each side, so you can power down individual outlets without unplugging anything—handy for energy saving and convenience when only a subset of devices is in use. The base is intentionally heavy with anti-slip rubber feet to resist knocks and slips, which is practical on busy desks or in shared spaces.

USB charging reality: what the ports deliver

The built-in USB charging station uses Smart IC technology to tailor charging speeds to connected devices. Expect automatic detection for safe, efficient charging at modest total output (up to 3.8 A across USB-C and USB-A). This makes it a reasonable fit for everyday gadgets, phones, tablets, and lightweight peripherals, though it’s not designed to power high-demand fast-charging setups simultaneously with other high-draw devices.

Safety and reliability you can feel on paper

Materials are fire-retardant, and there’s a safety door feature aimed at reducing accidental contact with live contacts. The unit carries CE, UKCA, and RoHS certifications and uses 100% copper wiring with a 13 A fuse in the plug. These details suggest a solid emphasis on basic safety and build quality for typical daily use, but as with any extension lead, avoid daisy-chaining or overloading with very high-wraw devices.

Who it’s for and who it isn’t ideal for

It’s a sensible choice for small home offices, student rooms, or workspaces where outlets are sparse and a compact footprint matters. If you routinely run multiple high-wattage devices at once or rely on rapid USB-C charging for power users, you may want to check whether the 3 USB-C ports and the total USB output suit your needs, especially if you expect to charge multiple laptops or power-hungry gear simultaneously.

What to check before buying

• Confirm your devices’ power draw aligns with the 13 A fuse and total USB charging limits.
• Consider whether a 1.5 m cord is long enough for your desk layout and whether the tower orientation fits your space.
• Think about the number of independent switches you’ll actually use day-to-day, four switches are handy, but they add a bit of complexity if you’re used to simpler strips.
• If you already have USB-C PD chargers or USB-A fast chargers, note how the Smart IC will distribute power among devices to avoid bottlenecks.

Practical use case: how it plays out in a real setting

In a small home office, you might position this cube on the desk corner. A laptop and monitor could be plugged into two AC outlets on opposite faces, a printer on another, and everyday peripherals like a webcam, speakers, or a lamp could be accommodated by the remaining outlets. The USB ports simplify charging phones and tablets while keeping cables tidy. The independent switches help you power down unused devices at night without unplugging anything—handy when you’ve got a few charging blocks and a cluttered cable stack.

How it compares to simpler alternatives

If you favour a slim, wall-adjacent strip, this tower offers better space optimisation at a desk level but with a slightly more complex setup. It’s likely more useful for compact desks or shared spaces where you need to reuse vertical space rather than a long flat strip that sits along the edge of the desk. If you don’t mind a vertical footprint and appreciate independent control for energy saving, this design makes sense. If you primarily need a basic power strip with fewer USB ports, a simpler flat model might feel more intuitive and cost-effective.

FAQ

• How many USB ports are available in total? The unit provides 6 USB ports (3 USB-C and 3 USB-A) in addition to 4 AC outlets.
• Is it safe for everyday office devices? It has fire-retardant materials, a safety door, and standard certifications (CE, UKCA, RoHS) with a 13 A fuse in the plug, which supports typical office use with sensible load management.
• Can I use it on a busy desk with heavy devices? The base is designed to be stable and anti-slip, but avoid overloading individual outlets and remember that heavy devices should be distributed across the 4 independent switches and outlets.

Is it worth it?

Final verdict: Worth considering if you prioritise space saving and the convenience of independent control for multiple devices. It suits compact desks and shared study spaces where USB charging and organised cables matter. Not the best pick if you routinely push the power strip to its limits with high-draw equipment or need a very long extension reach. If you value a tidy, modular setup and sensible safety features, this cube extension lead could be a practical addition to a home office or student room.
