The best extension leads with USB, compared.
Top pick: HAFINO 8-socket USB tower Best value: POWSAF 4-socket USB block – Lowest shelf price at about £9.99, with four sockets and USB. Score is held down by a Type C plug cell and smoke, spark and bang reports. Updated October 2026.
An extension lead with USB is a portable multi-socket block with a flexible cable, a UK three-pin plug, and USB ports in the same housing. You buy one in the UK when a wall socket is in the wrong place. Quality starts with a fused BS 1363 plug and a current rating you can stay inside, usually 13 A. USB sits on that limit. It is not extra power from the wall. Check the UK three-pin plug and its BS 1362 fuse, then the USB figure in watts or in volts and amps. USB-C without a stated Power Delivery wattage will not replace a laptop charger. A flat strip suits a skirting run. A tower uses less floor space. Switches cut standby devices and do not raise the amp rating. Surge figures address spikes, not overload. Use one lead per wall socket. Do not daisy-chain, and keep a kettle, toaster, microwave or heater off the block. Plug, amps, USB watts, spacing and length are on the [extension lead with USB buying guide](/hub/sockets-and-extension-leads/extension-lead-with-usb/sub/extension-lead-with-usb-buying-guide).

Question 1 of 2
Where will the lead sit?
The black HAFINO tower costs about £20.62 and is rated 4.7 from 2,224 reviews, with eight sockets, five USB ports, four switches and a 1.8 m cable. The title states 13 A and 3,250 W, and the bullets state 1,800 J plus a circuit breaker. USB output is up to 2.4 A per port and 5 A shared, with no Power Delivery wattage, and reviews say those ports stay on when you might want them off. Each of the four switches covers a pair of sockets, not a single outlet. Reviewers use the three-level night light in a kitchen or study, while one bedroom buyer covered a bright green power LED with a sticker. One review says the tower topples when many plugs are fitted, so it needs a stable surface. The plug field says Type G. No repeated electrical failure showed up in the first 50 UK reviews. It is one point behind the top pick and has no badge.
Pros
Cons
Best for: A kitchen, study or television corner where you want eight sockets, pair switches and a night light on one 13 A plug.
Less suitable: A bedroom that must stay dark, a laptop that needs a stated PD wattage, or a shelf where the tower can be pulled over.
Specifications
Common questions
Does each switch control one socket on the HAFINO tower?
Reviews say each of the four switches covers a pair of sockets, not one switch per socket. The title lists eight AC outlets.
Can all five USB ports draw 2.4 A at once?
The bullets say 2.4 A maximum per port and 5 A shared across the USB bank. Reviews note the USB section stays on.
What surge figure does this tower claim?
The surge field states 1,800 joules. The bullets also name a circuit breaker. Joules do not raise the 13 A limit.
The white HANYCONY HN6088 is about £14.98, rated 4.7 from 1,621 reviews, with four sockets, four USB ports and a 1.8 m braided cord. Reviews describe USB-A and USB-C, and they say those ports stay on and cannot be switched off. The mains sockets switch in pairs, which suits a workstation and does not let you kill one lamp on its own. Surge protection is claimed in the title and the bullets, and no joule figure is printed. The plug cell says Type B, with no Type G row. Several reviews in the file describe other lengths, so they may belong to a different variant. One buyer found the shutters would not open fully, so the plug did not seat, and another called the flex stiff. It is a mountable four-socket bar for a desk if you accept pair switching and an unstated joule rating.
Pros
Cons
Best for: A desk or caravan where two switched pairs and always-on USB ports match how you leave chargers plugged in.
Less suitable: A wall where you need a stated Type G cell, a joule figure, or a switch for each socket and for the USB bank.
Specifications
Common questions
Can you turn the USB ports off on this HANYCONY strip?
Reviews say the USB ports stay on and cannot be switched off separately from the pair switches on the mains sockets.
Does the listing state a joule rating?
The title and bullets claim surge protection, but no joule figure is printed. A surge claim does not raise the 13 A limit.
How do the double switches work?
Reviews describe mains sockets switching in pairs rather than one switch per socket.
The black KLINTOS JA-B01 tower is about £25.49, rated 4.7 from 1,163 reviews, with twelve sockets, two USB-C ports, four USB-A ports, four side switches and a stated 1,400 J. The title and the what-you-get line say a 2 m cable, while several reviews describe 5 m, so the length on your order may not match the title. The bullets state 13 A and 3,250 W, and they do not state a Power Delivery wattage. One buyer found USB charging slower than the listing. Reviewers like a switch per side on a desk or television unit. The reinforced plug neck is too rigid for a skirting socket for one buyer, and another called the housing a little flimsy. One unit arrived with the earth pin broken off. The buyer fitted a new plug, which is not a repair this page recommends. The plug field says Type C, with no Type G row. Twelve sockets still share one 13 A plug.
Pros
Cons
Best for: An office or television corner that needs many low-power plugs in one footprint and a stated 1,400 J figure.
Less suitable: A skirting socket that needs a flexible plug neck, a confirmed 5 m reach, or any high-load appliance beside the rest of the kit.
Specifications
Common questions
Is the KLINTOS cable 2 m or 5 m?
The title and what-you-get bullet say 2 m. Several UK reviews describe a 5 m cable. Treat that as a conflict and check the flex you receive.
How many USB ports does this tower have?
The bullets list two USB-C at 5 V / 3.1 A and four USB-A at 5 V / 2.4 A. No Power Delivery wattage is printed.
What plug type appears in the table?
The plug-type field prints Type C with no Type G row. Check the plug before you rely on a UK three-pin fit.
The SE UKASE tower at about £26.99 is rated 4.7 from 30 reviews, with six mains sockets, a 2 m cable and USB-C Power Delivery stated at up to 65 W from one port. The bullets say three USB-C ports support 20 W and one USB-A port is for ordinary charging. One review says a listing line that swaps those counts does not match the photos. Twenty UK reviews are in the file, which is more than the four-socket SE tower and still a small sample next to the JSVER and Addtam pages. Buyers describe a compact desk tower, a master switch that cuts mains and USB together, rubber feet, and fast charging that matches the 65 W claim in their own use. This comparison did not measure that wattage. Surge protection is claimed without joules, the plug-type cells are empty, and one review says the colour is grey rather than the black the table prints. A review mentions screws in the box, while the bullets describe a free-standing tower. It is the listing to open when a mid-size laptop needs a stated 65 W port and you accept 30 reviews as the evidence.
Pros
Cons
Best for: A home-office desk where one laptop needs the stated 65 W port and the other kit is monitors, a lamp and phones.
Less suitable: A buyer who wants a joule figure, a filled-in plug type, or a review file in the thousands before trusting a tower at about £26.99.
Specifications
Common questions
What is the maximum USB-C power delivery claim?
The bullets state up to 65 W from one USB-C port, with three ports supporting 20 W. This page did not measure that wattage. Match it to the laptop maker.
Does the master switch cut USB as well as mains?
Reviews describe one master switch for all devices, cutting mains and USB together.
Is this tower meant for wall mounting?
One review mentions screws in the box and says wall mounting would look odd on this shape. The bullets describe a free-standing tower, not keyholes.
The white SE UKASE four-socket tower is about £14.99, rated 4.7 from 30 reviews, with two USB-C and two USB-A ports sharing 5 V / 4.2 A and no Power Delivery wattage. Only three UK reviews are in the file, so the star line is too thin to treat as settled. The bullets claim individual switches, a surge light, safety doors, a 13 A fuse and 2,990 W, and they do not state a cable length. The same bullet that says 13 A also prints an input of 420 mA, which cannot both describe the mains load. The three reviews do not share a complaint. One buyer says it did not overheat in the first weeks. The title lists laptops, but a shared 5 V bank is phone and tablet charging, not a substitute for a laptop brick. Wait for a longer review file, or choose the HAFINO tower if you need eight sockets and a stated length.
Pros
Cons
Best for: A small tower trial for a television and phones if you can see the cable length before you rely on the reach.
Less suitable: A decision that needs hundreds of reviews, a known cable length, or laptop charging from USB-C.
Specifications
Common questions
How long is the mains cable on this tower?
Cable length is not stated. The bullets mention high copper wire but not a length. Check the listing before you rely on the reach.
Is there a conflict in the current figures?
The table lists 13 A while the same bullet prints input 420 mA. Those two figures cannot both describe the mains load.
Can this tower fast-charge a laptop?
The title lists laptops, but USB output is a shared 5 V / 4.2 A bank with no Power Delivery wattage stated.
Across 13,106 amazon.co.uk reviews at 4.6 stars, the white JSVER-PS3037 puts three mains sockets and four USB-A ports on a 24.5 x 5.1 cm bar with a 2 m lead, at about £11.99. Reviewers use that bar on a desk or in a holiday bag so a phone charger does not occupy a wall socket. Each USB port is listed at up to 2.1 A. Buyers call the charge reasonable rather than fast, and one still needed a USB-C adaptor. The table states 10 A at 240 V and 480 J, so this sits below the 13 A rows, and the sockets plus the USB ports share one fused plug. A review of this style says the printed 2 m can include the housing, which leaves less flex than the title suggests. The master switch is often described as flimsy. One buyer reported a loud pop and a flash after about three months with only a USB device connected, and the unit was then dead. It is the top pick for a low-price USB-A bar with a very large review file. Plan around the 10 A marking.
Pros
Cons
Best for: A bedside or desk where phones charge from USB-A and you only need three mains sockets.
Less suitable: A kettle or heater on the same lead, a laptop that needs USB-C Power Delivery, or a fourth mains plug.
Specifications
Common questions
Is the JSVER lead rated at 13 A?
The listing states 10 A maximum current, not 13 A. The three sockets and four USB ports share that one fused plug.
Can the USB ports fast-charge a laptop?
Each USB port is up to 2.1 A, and no Power Delivery wattage is stated. The listing does not claim USB-C or PD.
Does the stated 2 m length include the socket block?
The listing says 2 m. One UK review of this style says the printed length can include the housing, not only the flex.
The black JSVER-PS3037 is the same model number as the white bar, at the same about £11.99, with the same 4.6 from 13,106 reviews. Those two listing lines are one shared sample, so the black page does not add another 13,106 opinions. You get the same three sockets, four USB ports up to 2.1 A, a master switch, sliding shutters and a stated 480 J on a 2 m lead. The table weight is 440 g against 385 g on the white file, and the special-features line names USB slots where the white file also says surge protection. The plug cell again prints Type B beside Type G. The same review themes appear: a flimsy switch, a wish for four sockets, charging that is not fast, and one report of a pop and a flash after about three months. Choose the black finish when the desk is dark. Do not treat this page as a second test of the white lead.
Pros
Cons
Best for: A dark desk or travel bag where you want the JSVER bar in black and you already accept the 10 A limit.
Less suitable: Anyone counting the 13,106 reviews twice, or a setup that needs 13 A, USB-C or a fourth socket.
Specifications
Common questions
Is this a different product from the white JSVER lead?
It shares model JSVER-PS3037 and the same 4.6 from 13,106 reviews as the white listing. Treat that review sample as one shared pool.
Does the black version have surge protection in the listing?
The surge field says 480 J. The special-features line names USB slots. The white twin also says surge protection in special features.
Can you mount this bar on a wall?
The bullets do not claim wall mounting. Reviews describe a portable bar for a desk or bedside.
At about £13.99 the Addtam PS-UKW23C is an 11.6 x 10.6 cm block with two mains sockets, two USB-C ports and two USB-A ports, rated 4.6 from 12,963 reviews. The bullets state 13 A at 250 V, a braided 1.6 m cord and a shared USB bank of 4.5 A. They also state that the USB-C ports do not support MacBooks or other laptops that need 14–22 V. Reviewers find 1.6 m enough behind a television or on a windowsill, and one buyer used it in hospital where the wall socket sat high. Charging is often called slow, the cable stiff, and the block too heavy to pack for travel. Surge protection is named without a joule figure, and the plug cell says Type C beside Type G. Several reviews say the unit or the USB ports stopped after a few months, about eight months, or about three years, including a buyer who suspected swollen capacitors. It suits a short run with two plugs and phone charging.
Pros
Cons
Best for: A television side or windowsill with two mains plugs and phones or tablets on a shared 4.5 A USB bank.
Less suitable: A MacBook or other laptop that needs 14–22 V, a run longer than 1.6 m, or a bag you want to keep light.
Specifications
Common questions
Will the USB-C ports charge a MacBook?
The bullets state the USB-C ports do not support MacBooks or other laptops that need 14–22 V. Reviews describe USB charging as slow rather than laptop-grade.
How many mains sockets does this block have?
The title and bullets say two AC outlets. A catalogue field that prints 6 conflicts with that and is not a sixth socket.
Is the cable long enough behind a TV?
The lead is 1.6 m braided. Reviews call that enough behind a TV but too stiff or heavy for travel packing.
The HANYCONY HN4WUKC2 is about £15.99, rated 4.5 from 1,378 reviews, with four sockets, a switch on each one, two USB-C and two USB-A ports, and a 1.8 m braided cord. The four USB ports share 3.1 A, with no Power Delivery wattage, and one review left a laptop on a USB port overnight without a full charge. Two keyhole slots are claimed on the back. Reviews praise the braided cable and the individual switches behind a television or along a bed, and they note there is no status LED on the socket switches. Bulky adaptor plugs can hide those switches. One review says the USB sockets failed after about four weeks while the mains sockets still worked. A bullet also says a 6 ft cord beside the 1.8 m title, so measure the flex you receive if the run is tight.
Pros
Cons
Best for: A television unit or bed run where you want each socket switched and the bar fixed to the wall with the stated keyholes.
Less suitable: Laptop charging from USB, a dark room that needs a socket indicator, or a run you cannot measure because the 6 ft line and the 1.8 m title disagree.
Specifications
Common questions
Can bulky plugs block the individual switches?
Reviews say bulky adaptor plugs can hide the switches. Leave room for the rocker if you use large UK plugs.
Does this model have lit switch indicators?
Reviews say there is no status LED on the socket switches. One review notes a small light for the USB outlets.
Can it charge a laptop overnight on USB?
One review left a laptop on a USB port overnight and it was not fully charged. No Power Delivery wattage is printed.
The POWSAF UK615D-White is the about £9.99 lead here, a 12 x 12 cm block with four sockets, one USB-C port and three USB-A ports sharing 5 V / 3.4 A, rated 4.5 from 792 reviews. Buyers like that size under a bedside table or in a bag, and reviews describe an illuminated master switch rather than a switch on each socket. One review says the USB-C port is not Power Delivery, so a laptop still needs its own charger in a mains socket. Red and blue lights are too bright for a bedroom in several reviews. The plug field prints Type C only, with no Type G row, so check the plug in your hand before you rely on it. The first 50 UK reviews include smoking and a burnt front after a washing machine, sparking from the plug, and a bang as soon as one USB slot was used. Those reports are why a kettle or a washing machine does not belong on this block even though the title says 13 A and 3,250 W. It is the best value on shelf price. The failure reports are why the score sits below the larger review files.
Pros
Cons
Best for: A low-power bedside or travel kit if you check the plug is a UK 3-pin and you keep heaters and kettles off it.
Less suitable: A washing machine, a kettle, a dark bedroom, or a laptop that needs USB-C Power Delivery.
Specifications
Common questions
Does the USB-C port support Power Delivery?
One UK review says the USB-C port is not PD. The shared bank is 5 V / 3.4 A across all USB ports.
Are the indicator lights suitable for a bedroom?
Reviews describe red or orange and blue lights that stay on and are too bright for a bedroom.
What plug type does the listing show?
The plug-type field prints Type C with no Type G row. The title describes a UK four-way extension lead. Check the plug you receive.
The white AUNNO BKL-24 is about £19.99, rated 4.3 from 1,071 reviews, with four sockets, four USB-C ports and two USB-A ports on a 1.8 m cable. The bullets say each USB port is up to 5 V / 2.4 A and that the conductors are 3 x 1.25 mm², and the table states 1,800 J. Reviews describe a switch on each socket, and one says the fourth switch also has to be on for the USB ports to work. Another buyer expected a USB on/off from the pictures and did not get one. The amperage field prints 12.8 A while the bullets say 3,250 W, and the plug cell says Type B beside Type G. Switches need a hard press, the blue LEDs are too bright for a bedroom, and the sockets sit close together. Reported faults include a USB section too hot to keep using, a switch button that fell off, a buzzing third socket, USB-C ports dead on arrival, and rear screw holes that had not formed. At this price the switched HANYCONY bar costs less and shows fewer of those fault themes.
Pros
Cons
Best for: A desk where you want a switch per socket and several USB-C leads, if you will stop at the first sign of heat.
Less suitable: A bedroom, a wall-mount that depends on the rear holes, or a buyer who wants the quieter fault file of a cheaper switched bar.
Specifications
Common questions
Do the USB ports need a socket switch on?
One review says the fourth socket switch must be on for the USB ports to work. Another review mentions pictures of a USB on/off that the unit does not have.
Is this strip suitable for charging a laptop over USB?
Bullets list laptops among compatible devices and state 5 V / 2.4 A per USB port. No Power Delivery wattage is printed, so do not treat it as a laptop brick.
Have buyers reported heat from the USB section?
Review themes include a hot USB section on model BKL-24. Stop using a lead that is too hot to touch.
The SE UKASE four-socket lead at about £12.62 is rated 4.1 from 209 reviews, and it is one of only two listings here that state a USB-C Power Delivery wattage: 20 W, described as 5 V at 3 A max. The title also prints 1200 surge protection and a 2 m cable, with two USB-C ports, two USB-A ports and a stated 13 A / 2,990 W load. Reviews describe a master switch with a blue light that is too bright at night, and the bullets claim two rear keyholes and a 13 A fuse. The shape field says tower. This comparison lists the form as a strip, and reviews often call it a tower. Praise centres on four sockets plus USB for a desk or a caravan. More than one buyer says both USB-C ports snapped off after a few insertions, and others report a USB-C port that melted or smoked, including while nothing was plugged into that port. Further reports include smoke within seconds of plugging in, failure within weeks or about three months, and a unit dead on arrival. The 20 W claim is the reason to look at this ASIN. The failure cluster is why the score is the lowest in the set.
Pros
Cons
Best for: A desk that specifically wants a printed 20 W PD figure and will be watched for heat or a damaged USB-C socket.
Less suitable: Unattended overnight charging, a buyer who wants the larger review files, or anyone who needs the port to survive repeated insertions.
Specifications
Common questions
What wattage does the USB-C PD port claim?
The bullets state 5 V at 3 A max, 20 W, described as PD on the USB-C ports. That is below a typical laptop brick. This page did not measure it.
Have buyers reported problems with the USB-C sockets?
UK reviews criticise USB-C sockets that feel poor and tear. Other reports include a port that melted or smoked. Stop using a lead with a snapped or hot port.
Are wall fixings included?
Two rear keyholes are claimed. One review wanted rawl plugs, which were not in the box.
Twelve amazon.co.uk listings were scored for this page. Weights sum to 100. Shelf prices, stars and review counts are the figures stored on 20 October 2026. No lab test was run. The star line is the base. Review count, a stated joule figure, a stated 13 A load, switches, a stated Power Delivery wattage and a cable of at least 1.8 m add points. A plug cell that prints Type B or Type C, or leaves the plug type empty, a missing cable length, and failure themes take points off. The two JSVER colours share one review line, so the black listing is not a second sample. The best value badge is the lowest shelf price in the set. It is not the second-highest score.
Star line
45%The amazon.co.uk star rating is the base of the score. A 4.7 line starts higher than a 4.1 line. Stars are what the listing showed on 20 October 2026, not a lab result.
Review count
20%A count of 10,000 or more adds the most. A count under 150 loses points. The black JSVER does not get a second copy of the shared 13,106-review line.
Load, plug and cable
15%A stated 13 A load and a cable of at least 1.8 m add points. A Type B or Type C plug cell, an empty plug cell, or a missing cable length takes points off.
USB output as written
10%A stated Power Delivery wattage adds points. A USB-C hole with no wattage does not count as laptop charging. Volts and amps are taken from the listing, not measured here.
Switches and surge
10%A switch on each socket adds more than a master switch or pair switches. A stated joule figure adds a small amount. Joules do not raise the amp rating.
The checks run in this order: plug and fuse, current, USB watts, then form, spacing, cable length and switches. The table is the twelve stored listings. Joule figures and USB wattages stay seller claims. None of these leads was loaded in a lab for this page.
An extension lead with USB is a portable block of mains sockets on a flexible cable, fitted with a UK three-pin plug and at least one USB port in the same housing. UK shoppers use it to reach a wall socket and to charge a phone or tablet without taking a mains socket for a separate charger. The mains side is still one circuit through one plug. Electrical Safety First rates ordinary extension leads at 13 A, with some older leads at 10 A.
A title can list six holes and only two of them are 13 A sockets. Read the AC socket count, then the USB count. Both still share one fused plug.
13 times 230 V is 2,990 W and 13 times 250 V is 3,250 W. They are the same current claim. A larger fuse does not make the lead safe for a kettle plus a heater.
USB-C without a stated Power Delivery wattage is not a laptop charger. A shared 5 V bank is about phone charging. Stop if a port snaps, melts or runs too hot to touch.
Start with the plug. You want a UK three-pin plug and a BS 1362 fuse, normally 13 A on a 13 A lead. A catalogue cell that says Type B or Type C, or that leaves the plug type empty, is a data problem. Check the plug in your hand. The current rating is next. Electrical Safety First puts ordinary leads at 13 A, and some older leads at 10 A. The JSVER bars in this set list 10 A. The sockets and the USB ports share that one figure. USB comes after the mains limit.
Flat strips suit a skirting run. Towers use less floor space and often leave more room between large UK plugs. Two or three sockets plus USB suit a short desk. Large UK plugs still block neighbours on a tight strip, and bulky adaptors can hide individual switches. Cable length in this set is 1.6 m, 1.8 m or 2 m, except one tower that does not state a length. One KLINTOS title says 2 m while some reviews describe 5 m, so measure the flex you receive.
Three typical situations, each with a recommendation from this comparison.
You want about four mains sockets, USB-C holes and a cable that reaches on its own. The HANYCONY HN4WUKC2 is about £15.99, with 4.5 from 1,378 reviews, a switch on each socket, two USB-C and two USB-A ports sharing 3.1 A, and a 1.8 m braided cord. One review says the USB sockets failed after about four weeks.
A tower keeps a small footprint, and the whole stack still shares one 13 A plug. The HAFINO tower is about £20.62, with 4.7 from 2,224 reviews, eight sockets, five USB ports and 1,800 J stated. Each of the four switches covers a pair of sockets. It can topple when many plugs are fitted.
You need a stated Power Delivery wattage that matches the laptop maker. In this set that is the SE UKASE tower at about £26.99, with up to 65 W claimed on one USB-C port and 4.7 from 30 reviews. This page did not measure that wattage. The plug-type cells are empty.
The top pick is the white JSVER 3-socket strip at about £11.99, with 4.6 from 13,106 reviews, four USB-A ports, a stated 480 J and a 2 m lead. It is listed at 10 A, not 13 A. The black twin shares that review line and has no badge. The best value is the POWSAF four-socket block at about £9.99, the lowest shelf price here, with 4.5 from 792 reviews. It is not the second-highest score. The HAFINO tower is one point behind the top pick and has no badge. The POWSAF plug field prints Type C only, and stored UK reviews include smoke, spark and bang reports.
POWSAF 4-socket USB block
Lowest shelf price at about £9.99, with four sockets and USB. Score is held down by a Type C plug cell and smoke, spark and bang reports.
