The best power cubes, compared.
Top pick: Fellowes Power Cube Best value: JSVER 3-outlet cube, 2 m – About £13.99, the next cabled cube in the £13–£14 band with more than 1,000 reviews. 4.6 from 4,435 reviews and a claimed 2 m lead. Not the cheaper wall cube. Updated October 2026.
A power cube is a compact multi-outlet block whose sockets sit on the faces of a cube, not in a line on a strip. You buy one in the UK for a desk or a bedside when several plugs need a small footprint. Some units have a short cable and a BS 1363 plug. Others plug straight into the wall. Extra faces do not add extra current. Every AC outlet shares one 13 A fuse. USB-A and USB-C sit on a separate, much smaller budget and do not raise that limit. A kettle can use the whole budget. Do not daisy-chain. A wall cube is a block adaptor. Fire services prefer a fused inline lead to a plug-in cube, because plug weight can pull it out of the socket. That choice is set out in the [wall cube or cabled cube guide](/hub/sockets-and-extension-leads/power-cube/sub/power-cube-wall-or-cable). A flat body or a tall tower is a different product. A hot plastic smell, scorch marks or sparks mean you unplug.

Personal buying guide
Question 1 of 2
Where will the cube sit?
The Fellowes Power Cube, model 100136979, is a named cube with three 230 V sockets, two USB-C ports at 20 W max, one USB-A at 18 W max and a 2 m cable, listed at £24.99. The customer-review line is 4.8 from only seven reviews, with four UK review blocks in the file, so that star line is not a stable signal next to thousands of reviews on the cheaper cubes. One UK review notes there is no red glow when the power is on, which matters if a neon bothers you at the bedside. Bullets mention a five-year limited warranty and an on/off button. The load is not stated beyond 230 V sockets, and the listing asks about surge protection without printing a joule figure. At 630 g it is the heaviest cabled cube here. Pay the extra only if the brand name and the warranty line matter more than a large review sample.
Pros
Cons
Best for: A bedside or desk where you want the Fellowes name, a 2 m lead and a warranty line, and you accept a tiny review sample.
Less suitable: Anyone who needs a large review count or a printed 13 A mark before they buy.
Specifications
Common questions
What USB power does the Fellowes cube claim?
Bullets say 2 USB-C at 20 W max and 1 USB-A at 18 W max.
Is there a night-time glow?
One UK review says there is no red glow when the power is on.
How many reviews sit on the listing?
The customer-review line is 4.8 from 7. The raw file has 4 UK review blocks.
The BEVA MFPC-008WUK1.5 puts four UK outlets and three USB ports on a cube about 8.5 cm across, with a 1.5 m lead and a switch on the top, listed at £13.59. Across 5,355 amazon.co.uk reviews the line is 4.6, the largest sample in this set, which is why it is the top pick for a desk that needs a fourth plug. The USB line is 5 V 2.4 A shared, so it suits phones and small accessories rather than a laptop. The comparison table prints both a 13 A maximum and a 10 A amperage, and the colour row says Gray while the title says WHITE, so you should read the carton. The protection field prints 3,250 W where a surge rating might be expected; that figure is a load claim, not joules. Shutters are not stated. A kettle can still consume the whole shared fuse, the same as on every other cube here.
Pros
Cons
Best for: A desk or bedside where you want four plugs, a reachable switch and phone charging, and you will read the carton for colour and the amp mark.
Less suitable: Laptop USB-C charging, a kettle plus other heaters, or anyone who needs a printed surge rating in joules.
Specifications
Common questions
How many sockets and USB ports does this BEVA cube have?
The table lists 4 outlets and 3 USB ports. Bullets say 5 V 2.4 A shared across the USB ports.
Is the load 13 A or 10 A?
The listing prints both. Maximum current is 13 A and amperage is 10 A. Read the mark on the product.
Does the cube have a switch?
Yes. Bullets describe an on/off switch on the top.
This JSVER JSVER-PS3131 is a cabled cube with three AC outlets, three USB ports and a claimed 200 cm lead, listed at £13.99. The amazon.co.uk line is 4.6 from 4,435 reviews, close to the BEVA sample, which is why it is the best value when you want a similar star line and a longer claimed cable for about 40p more. One UK review says the wire is about a metre, so treat 2 m as a claim until you measure the lead. The listing prints plug Type G and plug Type B, and it also prints 13 A beside an amperage of 10 A. Some reviews describe years of use; others say the USB ports died after about 2.5 years while the AC sockets still worked, or that both units failed after a month. Safety covers on unused outlets are named, which the BEVA row does not state. It will not give you a fourth mains face or USB-C power delivery.
Pros
Cons
Best for: A desk where three mains sockets are enough and a longer lead would help, once you have measured the flex.
Less suitable: Buyers who need a confirmed 2 m lead, a fourth AC outlet, or USB-C power delivery.
Specifications
Common questions
How long is the JSVER cube cable?
The title and bullets say 200 cm. One UK review says the wire is about a metre. Treat 2 m as a claim.
Is the plug Type G or Type B?
The listing prints both. Power plug type is Type G. Plug type is Type B. Confirm the pin shape on the product.
Do the USB ports last?
Some reviews say years of use. Others say USB died after about 2.5 years while AC still worked, or both units failed after a month.
The JSVER JSVER-OT4021 is a wall cube with no flex: four AC outlets and two USB ports, listed at £12.99. The star line is 4.6 from 696 reviews, which looks strong until you read the heat notes. Reviews mention a burnt smell, melted fuses, a unit that got extremely hot, and a pin that was loose from arrival. Other reviews say a bulky plug blocks the USB ports and that the adaptor walks out of the wall under the weight of plugs, which matches the Which? warning about block-adaptor weight. USB is 5 V 2.4 A and 12 W total, with no USB-C. A switch is not stated. London Fire Brigade prefers a fused inline lead to this plug-in form, so it is reasonable only for light chargers that stay seated.
Pros
Cons
Best for: A fused wall cube for a phone and a radio on a socket you can see and unplug.
Less suitable: Kitchens, kettles, heavy power supplies, or any socket you cannot watch.
Specifications
Common questions
Does this JSVER cube have a cable?
No. It is a wall plug cube. The title calls it a wall socket extender.
Can I use all four sockets at once?
Some reviews say four plugs plus USB still fit. Others say a bulky plug blocks the USB ports and that the adaptor walks out of the wall under weight.
Did reviews report heat?
Yes. Reviews mention a burnt smell, melted fuses, a unit that got extremely hot, and a loose pin from arrival.
The UGREEN 45036 is listed at £15.99 with two AC outlets, three USB-A ports and one USB-C port claimed at 20 W. The body measures 12.5 x 7.8 x 3.3 cm and the shape field says Flat, while the bullets call it a cube, so it sits in this table as a compact lead whose fit is uncertain. Across 838 reviews the line is 4.4. AC outlets are rated 2,990 W at 13 A, which is still one shared budget. USB-C at 20 W can top up a phone or a small tablet; if several USB ports are used together the bullets drop the USB total to 15 W. Reviews praise the port mix, and others say the USB board failed within 6–12 months or that USB power cuts when another device is plugged in. You get a stated two-year manufacturer warranty and internal shutters, which several cubes here leave blank.
Pros
Cons
Best for: A slim desk brick with two plugs and a 20 W USB-C port for a phone or small tablet.
Less suitable: Anyone who needs sockets on several faces, or more than two mains outlets.
Specifications
Common questions
Is this UGREEN unit a cube?
Bullets call it a cube extension lead. The shape field says Flat and the size is 12.5 x 7.8 x 3.3 cm. Fit is uncertain.
What is the AC load?
Bullets say the AC outlets are 2,990 W (13 A). Do not exceed that total.
Do the USB ports stay on?
Reviews praise the USB mix. Other reviews say the USB board failed within 6–12 months, or that USB power cuts when another device is plugged in.
The Status S3W1.4M3XUSB1PK6 is a white cabled cube with three 13 A outlets, three USB ports and a 1.4 m lead, listed at £13.98. It scores 4.4 from 791 amazon.co.uk reviews, a mid-size sample below the two largest cubes. The maker address in the file is Bradford, which helps if you want a UK seller line, though that does not change the shared 13 A fuse. Several reviews describe an on/off switch even though the short bullet list does not name one. The technical table prints plug Type B beside a title that describes a 3-pin cube, so check the pins on arrival. Most reviewers use the USB ports; one says the mains sockets worked and all USB ports were dead on arrival. Dimensions are not in the table.
Pros
Cons
Best for: A white bedside or desk cube with a short 1.4 m lead and ordinary phone USB.
Less suitable: Anyone who needs the plug type unambiguous on the listing, or a USB-C port.
Specifications
Common questions
How long is the Status cube lead?
The title and item length both say 1.4 m.
Does it have a switch?
The short bullet list does not name a switch. Several UK reviews describe an on/off switch.
Did USB work on arrival?
Most reviews use the USB ports. One review says the 3-pin sockets worked and all USB ports were dead on arrival.
The ROOTOMA cabled cube offers three UK outlets, two USB-A ports and two USB-C ports on a lead the colour name calls 2 m, listed at £13.94. It scores 4.4 from 218 reviews, a smaller sample than the BEVA and JSVER cabled cubes. Bullets cap USB-C at 15.5 W and the whole USB budget at 15 W, so a laptop will not see a proper power-delivery charge. Child-safety shutters and a master switch with an indicator are named, which is clearer than several rows here. UK reviews include a title about a fire hazard and burned chargers, and another that says the unit overheated and melted a charger cable. The outlets field prints 7 because it counts USB ports, so the mains count is three. At this price the port mix looks generous until those heat reports.
Pros
Cons
Best for: A desk that wants USB-C sockets for phones, if you will unplug at the first sign of heat.
Less suitable: Overnight charging, laptop power delivery, or anyone put off by the heat reviews.
Specifications
Common questions
How many UK sockets are on the ROOTOMA cube?
Bullets say 3 UK outlets plus 2 USB-A and 2 USB-C. The outlets field prints 7 because it counts USB.
Will USB-C fast-charge a phone?
Bullets say up to 15.5 W on USB-C and 15 W total across all USB ports. Reviews say USB-C can run hot and charge slower than a wall charger.
Did UK reviews report heat?
Yes. One review titled fire hazard reports burned chargers. Another says the unit overheated and melted a charger cable.
The VoltFlow cube is the power-delivery row in this set: three UK outlets, two USB-A ports, two USB-C ports and a 1.5 m lead, listed at £21.25. Bullets say C1 supplies 65 W only when it is used alone; with other USB ports active, C1 drops to 45 W and C2 to 15 W. Reviews report about 62–63 W and jerky input on one HP laptop, so treat 65 W as a claim beside those figures. The specification-met field prints BS1363 and the plug is described as a 13 A fused UK plug, which is clearer than the Type B conflicts elsewhere. The star line is 4.2 from 133 reviews. Reports include USB dead on arrival, USB-C dead after a few months, and a replacement from the seller. You pay a mid-band price for a laptop-shaped claim that falls once the other USB ports are busy.
Pros
Cons
Best for: A desk laptop that can take the C1 port alone, if you accept a thinner review sample.
Less suitable: Charging a laptop while phones use the other USB ports, or buyers who want thousands of reviews.
Specifications
Common questions
Will this cube charge a laptop at 65 W?
The bullets say C1 supplies PD 65 W only when used alone. With other USB ports active, C1 is 45 W and C2 is 15 W. Reviews report about 62–63 W and jerky input on one HP laptop.
Does the listing name a UK standard?
Yes. The specification-met field prints BS1363 and the bullets say a 13 A fused UK plug.
Did USB-C fail in reviews?
Yes. Reviews include USB dead on arrival, USB-C dead after a few months, and a replacement sent by the seller.
Eight amazon.co.uk listings were scored for this page. Weights sum to 100. Shelf prices, star ratings and review counts are the figures in the stored listings, dated 21 October 2026. No lab test was run. The star line is stars divided by 5, then multiplied by 50. Review depth uses the largest sample in this set, 5,355, as the top of the scale. The top pick is the highest score. The best value is the next cabled cube in the same about £13–£14 band with more than 1,000 reviews. The cheaper wall cube is not that pick.
Amazon star line
50%amazon.co.uk stars divided by 5, then multiplied by 50. This is the largest block. A raw 4.8 from a handful of reviews is not left as a near-perfect mark once review depth is applied. There was no lab test.
Review depth
20%log10 of the review count, divided by log10 of 5,355, then multiplied by 20. The largest sample in this set is the top of the scale. Seven reviews add only a small amount, even when the star line is 4.8.
Price band
15%About £13–£14 scores 14 or 15. £15.99 scores 12. £21.25 scores 8. £24.99 scores 6. The band is the shelf price in the stored amazon.co.uk listing, not a street-price survey.
Listing clarity
15%Starts at 15. Points come off for conflicts, heat reports, a missing load and plug-type clashes. A 3,250 W cell is a load claim, not a joule surge rating, and it does not add points. A 65 W USB-C claim scores only with the alone-port condition. USB watts do not add AC capacity.
The checks run in this order: cabled cube or wall cube, a Type G plug and fuse, the shared 13 A load, then the USB claim and whether a watt figure is load or surge. The table is the eight stored amazon.co.uk listings. Watt and USB figures stay seller claims. None of these cubes was tested in a lab for this page.
A power cube is a compact multi-outlet block whose sockets sit on the faces of a cube, not in a line on a strip. Some units have a cable of about 1.4–2 m and a BS 1363 plug. Others plug straight into the wall and count as block adaptors. Extra faces do not add extra current. Every AC outlet shares one 13 A fuse. USB-A and USB-C are a separate, much smaller budget and do not raise that 13 A limit. A flat body sold as a cube, or a tall tower, is a different product.
Four faces are not four times 13 A. USB ports do not raise the plug fuse either. Add the current of everything that may run at once. Use one extension device per wall socket, and do not daisy-chain.
A 3,250 W cell is a load claim, even if the table says surge. A surge rating is a joule figure. Do not pay extra for watts you have already counted as the 13 A load.
Heat, a burnt smell, a melted charger cable or a cube that walks out of the socket is a stop, not a quirk. Unplug. Do not leave a hot USB-C cube on overnight, and do not hang a kettle on a wall cube.
Choose the family first. A cabled cube suits a desk or a bedside. A wall cube is only for light loads you can watch. A flat body is not the same as sockets on several faces, and a tower is a different comparison. Then read the plug. You want Type G and a BS 1362 fuse, with shutters when the listing states them. In this table, Type G is the cleaner line on the BEVA, UGREEN, ROOTOMA and JSVER wall cubes. The JSVER cabled cube prints Type G and Type B.
Read the USB line narrowly. BEVA, the JSVER cabled cube and the JSVER wall cube state 5 V 2.4 A, which suits phones. The wall cube also states 12 W total and no USB-C. ROOTOMA states two USB-C ports, capped around 15.5 W, with 15 W shared, and reviews report heat. UGREEN states USB-C at 20 W, and 15 W total when several USB ports are used. The shape field says Flat. VoltFlow states 65 W on C1 only when that port is used alone; otherwise the claim drops, and reviews include USB-C failures.
Three typical situations, each with a recommendation from this comparison.
You want the cube on the worktop, a switch you can reach and a fourth mains face. The BEVA 4-way cube with 3 USB is the top pick at about £13.59, with 4.6 from 5,355 reviews, a 1.5 m lead and a top switch. The table also prints 10 A beside 13 A, and the colour row does not match the title.
You want USB and a switch you can reach, on a short lead. The Status 3-way white cube is about £13.98, with 4.4 from 791 reviews and a stated 1.4 m lead. Reviews describe a switch that the short bullets do not name. The plug row prints Type B.
Use a fused inline cube, not a wall cube. The JSVER 3-outlet cube, 2 m is the best value at about £13.99, with 4.6 from 4,435 reviews and a switch. A kettle can use the whole 13 A fuse. Do not add a toaster on the same cube. One review puts the cable near a metre.
The top pick is the BEVA 4-way cube with 3 USB at about £13.59. It has the highest score in this set: 4.6 from 5,355 reviews, four AC outlets, a 1.5 m lead and a switch on the top. The table prints both 13 A and 10 A, the title says WHITE and the colour row says Gray, and 3,250 W is a load claim, not joules. The best value is the JSVER 3-outlet cube, 2 m at about £13.99, the next cabled cube in the same price band with more than 1,000 reviews. It has 4.6 from 4,435 reviews and a claimed longer lead. It is not the wall cube at about £12.99, which is cheaper and has heat and walk-out reports. This page did not run a lab test.
