Best for switched mains sockets

The top pick is the Masterplug MSWRG3-MP, B004I5BQ42, at about £8.25. It is 4.6 from 5,929 reviews, score 85, with a switch on each of three sockets and a weight of 158 g. In the first 50 UK reviews, people use those switches and like the side faces for a night-light plug. The bullets claim a surge indicator, with no joule figure, and say not to use it if the light is out. Skip it if you still need the other half of a double socket. Reviews say the body covers the spare outlet or one of its own faces. Skip it in a dark bedroom: the LEDs are called very bright. Several reviews say the switches get hot, including with a phone charger. The table prints Type B beside Type G, and two USB ports the bullets never describe. Opened for USB, this is the wrong row. The checks sit on the socket cube buying guide.

Best value if the plugs are small

The best value is the NAEEM SONS cube, B0F88SRPWX, at about £4.30. It is 4.6 from 947 reviews, 60 g, Type G, 230 V, score 83. In the first 50 UK reviews, people use it for a small plug such as a toothbrush charger. The case for it is the price, the review count, and the lack of a severe-heat penalty. Skip bulky plugs. Reviews say large moulded plugs would not go in. The title says 2-way and the outlet field says 3. No fuse is named. The pack of two, B0GDZ7H25C at about £5.49, repeats the clash, at 4.5 from 55, with seven short praise notes in the file. Count the faces on the pack you open.

USB and the short lead, only if that is the job

USB here is phone charging at about 12 W. LENCENT B09GLQRR5W scores 83 at about £14.99, 4.6 from 775, with three AC outlets, two USB ports at 12 W, and child doors claimed. A live snippet the same day showed £12.74. The body is 7.1 × 6.5 × 7.1 cm. A bathroom is named, with no IP rating. Watts are on socket cube with USB. JSVER at about £12.99 scores 76 because reviews describe melting and blown fuses, USB unused. Chemilen at about £13.99 names USB-C up to 15.5 W, at 4.1 from 20 reviews. Status at about £13.98 is the 1.4 m lead, plug field Type B, score 71, with no watts printed. Take Status for 1.4 m. Take LENCENT for 12 W and a Type G line, off any lead.

What this score will not call best

A 4.6 line is not a crown where notes describe melting, a burnt smell, a blown fuse, or pins hot enough to burn. That penalty is 14 points, on the JSVER and on FAMHOME B0BXM4Z2JR. FAMHOME is a two-way block, 46 × 46 × 114 mm, about £6.99 for two, 4.6 from 837, score 78. Reviews describe a prong that burnt a hand. No fuse is named, so the price is not the best-value pick. Double Dragon B0FDTTKZNR at about £4.93 scores 79, and a review says there is no fuse and no CE mark on the item. If your listing mentions melting or a missing fuse, leave it. Lead or wall block is socket cube vs extension lead.

Common questions

Which cube in this set is the top pick, and for what job?
The top pick is the Masterplug MSWRG3-MP, B004I5BQ42, at about £8.25, for switched mains on one wall outlet. The score is 85, from 4.6 and 5,929 reviews, with deductions for a Type B cell, a USB count the bullets omit, switch heat, and bright LEDs. Leave it when you need both halves of a double socket, or when you came for USB.
Why is a 4.6-star USB cube not the winner?
JSVER scores 76 despite 4.6 from 696, because reviews describe melting and blown fuses with the USB unused. FAMHOME scores 78 despite 4.6 from 837, because reviews describe hot pins. The score records heat and whether a fuse is named. Stars alone do not make a bedside block.
Is the Chemilen a best buy because it has USB-C?
Chemilen B0GT28TW63 at about £13.99 prints USB-C up to 15.5 W, a claimed 13 A fuse, and a switch. The line is 4.1 from 20 reviews, and one reviewer says about 3.1 A is shared. The outlet field says 7 by adding USB to three mains faces. It is a short sample, not a 65 W charger, and not the top pick.
What should I skip if reviews mention melting or no fuse?
Skip the JSVER for melt and blown fuses, and the FAMHOME for hot pins, even at 4.6. Skip the Double Dragon if you need a fuse the listing names: a review says there is none. A high star line does not cancel those notes.
Are IKEA and UGREEN in this table?
They are not. IKEA’s KOPPLA was about £4 with 4.3 from 75 on the IKEA page. UGREEN’s DigiNest was a 1.8 m lead with 65 W USB-C. Neither ASIN is scored here. If you need 65 W, you are outside these ten rows.
