You still need the 13 A socket
A lamp, a fan or a radio has to stay plugged in beside the phones. The LENCENT double with USB keeps two outlets stated at 13 A and adds three USB ports, with the USB budget printed as 3.4 A total rather than 3,250 W.
USB plug adapter comparison 2026
The best USB plug adapters, compared.
Top pick: LENCENT double with USB – Type G plug-through with two 13 A outlets, a stated USB budget of 3.4 A total, and 4.7 from 671 amazon.co.uk ratings describing a firm fit. Best value: Rekavin 20 W USB-C – Type G, one USB-C and one USB-A, 20 W claimed, about £6.37, with 4.4 from 3,421 ratings and no cable in the box. Updated October 2026.
A USB plug adapter is the small block you put into a British socket when a phone, headphones or a tablet needs a charge and you do not want a full extension lead. On amazon.co.uk that search mixes three objects: a charger plug that turns the socket into USB only, a plug-through that keeps 13 A outlets and adds USB, and a travel block for European sockets that may not accept a British plug. How to choose between those three forms is set out in the [USB plug adapter buying guide](/hub/sockets-and-extension-leads/usb-plug-adapter/sub/usb-plug-adapter-buying-guide). A travel block is for a socket abroad, and the pins that stick out decide whether it belongs in Britain or in. People are usually charging phones at a bedside, sharing a tight double socket, or packing for a holiday. For a British bedroom the pins must be Type G.

Which USB plug adapter fits?
Question 1 of 2
Do you still need a 13 A plug in the same socket?
The best USB plug adapters in detail
Our view
The LENCENT WW07-G2b-C2U is a Type G plug-through at £11.89 with two AC outlets stated at 250 V, 13 A and 3,250 W, plus three USB ports, two USB-A and one USB-C. USB current is 3.4 A total, with USB-A at 2.4 A max and USB-C at 3 A max, so the 3,250 W figure is the mains side. It is 4.7 from 671 amazon.co.uk ratings, the joint highest star line in this set, and the sampled UK reviews praise a firm fit and USB ports on top. Buyers use it so awkward plugs can sit side by side, and one prefers it to a cable extension. The first sample of 50 UK texts does not repeat a defect. There is no IP rating, no surge figure and no BS number in the file, and the bathroom and surge questions on the page are unanswered. At 162 g and 11.4 cm by 5.2 cm, with a two-year manufacturer warranty, it is the top pick when you must keep 13 A outlets and add USB on the same socket. Skip it if you only need a slim phone head and cannot spare the width.
Pros
- Type G, with two 13 A outlets kept and three USB ports
- 4.7 from 671 ratings, and sampled reviews praise a firm fit
- USB budget is stated as 3.4 A total, separate from the 3,250 W AC side
- Two-year manufacturer warranty, 11.4 cm by 5.2 cm
Cons
- No IP rating, so not a bathroom or outdoor rating
- No surge figure, and the page does not answer the surge question
- No BS number is printed in the file
- Wider than a slim charger plug, at 162 g
Best for: A single or double socket where a 13 A plug and USB devices must share the outlet.
Less suitable: A bathroom, a tight space that only has room for a slim head, or a high-watt USB-C laptop charge.

Our view
The DAYEFORUN two-pack is £14.88, 4.7 from 113 amazon.co.uk ratings, and it ranks in International Power Adapters. The attribute line says Type G, the input is 230 V AC, and a bullet claims a 10 A fuse. USB-C is stated up to 9 V at 3.1 A and USB-A up to 5 V at 4.1 A when each port is used alone. UK reviews do not agree on the object: one says it is an EU USB charger and will not take a 13 A plug, and another describes a UK outlet. Holiday texts say it charged phones and tablets from USB and fitted European sockets without wobbling on a trip to Germany. It gets quite hot after a short time, a bright blue light disturbed sleep, and with MagSafe plus a watch one review says only the watch charges. BS 8546 is not printed, so do not pick one pin direction from this file. Pack it only after you have seen the pins you need, and do not use it as an unambiguous British bedroom plug.
Pros
- Two-pack at £14.88, 4.7 from 113 ratings
- Input stated as 230 V AC, which matches UK and continental Europe mains
- Per-port USB figures are printed for use one port at a time
- Holiday reviews describe charging phones from European sockets
Cons
- Title, Type G line and reviews disagree on whether a 13 A plug fits
- Gets quite hot, and a bright blue light disturbed sleep
- 10 A fuse is a bullet; BS 8546 and BS 1362 are not printed
- With MagSafe and a watch, one review says only the watch charges
Best for: A traveller who has already checked which pins stick out and only needs USB for a phone.
Less suitable: A UK bedroom plug, a 13 A hairdryer, or anyone who needs one agreed pin direction in the listing.

What is in the pack?
Two adapters.
Our view
The Aioneus HNT-PD2002RZ is a Type G four-port plug at £9.99, and the listing claims up to 40 W total with PD and Quick Charge. Title and port field agree, which is uncommon in this set, and the bullet says the cable is not included. The star line is 4.5 from 7,407 amazon.co.uk ratings, the largest count here, and the rank line is number 1 in Mobile Phone Mains Chargers. Reviewers charge several devices at once and call it solid when a fast-charge lead is used, including in a hotel with few sockets. One buyer saw no overheating with iPhones, iPads and AirPods, while another says it gets very hot if more than two ports are used. Output is printed as 5 V at 3.1 A, so the 40 W figure is a headline total, not a promise on every port together. At 90 g with an 18-month warranty it suits a USB-only socket where you leave some ports empty when you want speed, and you should skip it if the 13 A hole must stay free.
Pros
- Type G, and the four-port count agrees
- Up to 40 W total claimed, with PD and Quick Charge named
- 4.5 from 7,407 ratings, rank 1 in Mobile Phone Mains Chargers
- Cable absence is stated in the bullet
Cons
- Gets very hot if more than two ports are used, in one UK review
- No cable in the box
- 5 V at 3.1 A is the printed output, so 40 W is not on every port at once
- The plug occupies the socket and leaves no 13 A outlet
Best for: Several phones on one Type G socket when you can leave ports empty to keep the charge quicker and cooler.
Less suitable: A lamp or any 13 A plug that must stay in the same outlet, or a charge with no cable of your own.

Our view
The Saqykan HNT-PD3510 is a Type G charger plug at £8.49, and the title claims 40 W across two USB-C and two USB-A ports, with PD and Quick Charge 3.0 named. It is 4.5 from 6,560 amazon.co.uk ratings and ranks number 2 in Mobile Phone Mains Chargers in this capture. Reviewers call it compact, light and sturdy, and one owner who already had one says it has not run hot. Other texts say it sometimes gets hot, and one unit’s shell separated from the pin block and broke when it was unplugged. One buyer returned it because the body was too wide for a double socket. The total-USB-ports field says 6, which does not match the four-port title, and a cable is not named. At 60 g with an 18-month warranty it is a busy bedside plug if your socket has the width and you treat 40 W as a shared total, though you should skip it if a split shell in the sample is enough to put you off.
Pros
- Type G, with two USB-C and two USB-A named in the title
- 40 W claimed at £8.49, with 4.5 from 6,560 ratings
- Ranked 2 in Mobile Phone Mains Chargers in this capture
- ABS and polycarbonate shell, stated weight 60 g
Cons
- Port field says 6 against a four-port title
- Sometimes gets hot, and one shell separated from the pin block
- Too wide for one buyer’s double socket
- A cable is not named in the file
Best for: A single socket that can take a wide 40 W Type G body, if you treat 40 W as the whole plug.
Less suitable: A tight double socket, or anyone who needs the port count to agree and a shell with no split in the sample.

Our view
The Rekavin four-pack is £10.99 for four Type G USB-A plugs stated at 5 V at 1 A. The star line is 4.5 from 413 amazon.co.uk ratings. Short reviews call them reliable overnight chargers and good value, one buyer used the bottom USB port on a waterproof socket for outdoor cameras, and the listing itself is not fast. One pack failed within about a week and then more plugs failed, and another arrived with a broken earth pin that jammed in an MK 13 A socket. One buyer calls them a double-socket type, which is not this title, so that text may be mixed. At 140 g for the pack and a six-month warranty they are spare slow heads for rooms that already have cables. Skip the pack if a damaged earth pin is a risk you will not accept, or if £10.99 should buy a 20 W USB-C plug instead.
Pros
- Four Type G plugs, and the port field agrees
- 5 V at 1 A is printed, so the slow rate is explicit
- 4.5 from 413 amazon.co.uk ratings
- Bottom USB port used in one review for outdoor cameras
Cons
- Not a fast charge, at £10.99 for the pack
- Early failure of one or more plugs in one review
- Broken earth pin on arrival, jammed in an MK socket
- One review describes a double-socket type that is not this title
Best for: Four rooms that only need a slow overnight USB-A charge and already have cables.
Less suitable: A fast USB-C phone, or a buyer who will not risk a damaged earth pin in a 13 A socket.

Our view
The toomke listing is £13.29 and the bullets claim one AC socket at 250 V, 13 A and 3,250 W plus four USB ports, with one USB-C stepped through 5 V at 3 A, 9 V at 3 A, 15 V at 2.33 A and 20 V at 1.75 A, up to 35 W. The plug attribute says Type B, not Type G, while the title sells it as a UK adapter. The star line is 4.5 from 407 amazon.co.uk ratings. Reviewers like keeping a 13 A socket free, and one kitchen-counter user saw Android phones charge quickly. Heat is the repeated complaint, from very hot over a month to hot on first use, and one report describes a sparking noise after about two months. One unit sparked, popped, blew a fuse and then stopped working, and a Samsung owner doubts the red USB-C port is 35 W because the phone draws more on another charger. A bullet lists a bathroom among places to use it, there is no IP rating, and you should leave it for a British socket while the attribute line says Type B.
Pros
- Claims one 13 A socket plus two USB-A and two USB-C
- USB-C PD steps are printed, up to 35 W on one port
- 4.5 from 407 ratings
- Reviewers value keeping a mains socket while adding USB
Cons
- Plug attribute says Type B, not Type G
- Repeated heat, including on first use and over a month
- One report of sparking, a pop and a blown fuse
- A bathroom is named in a bullet and no IP rating is printed
Best for: Nobody on a UK three-pin socket until the plug line says Type G and the heat reports are weighed.
Less suitable: A British wall socket, a bathroom, or a Samsung owner who needs the stated 35 W on the first charge.

There is no IP rating. A bullet lists a bathroom among places to use it, which is not a rating.
Our view
The Aioneus 33 W listing is £8.49 and the title says a UK four-port charger, with a Quick Charge port claimed up to 18 W inside a 33 W total. The power-plug attribute says Type A, two-pin, North American, not Type G. The star line is 4.5 from 348 amazon.co.uk ratings, but the file contains only two UK review texts and both describe decorative items, not a charger, so they cannot support a charging claim. The bullet mentions USB-C while the connector field says USB Type A only, and the output-voltage lines print both 240 V and 5 V. A user manual is named and a cable is not. The warranty line is 18 months and the weight is 90 g. Leave this row for a British socket until a Type G line and reviews that mention a plug are on the page.
Pros
- 33 W total claimed, with one QC port up to 18 W, at £8.49
- Star line of 4.5 from 348 ratings
- 18-month warranty line
- Port count of four agrees between the bullet and the field
Cons
- Plug attribute says Type A, two-pin, not Type G
- The two UK texts describe ornaments, not a charger
- USB-C in the bullet, USB Type A only in the connector field
- Output voltage prints both 240 V and 5 V
Best for: Nobody buying for a UK socket, until the plug line says Type G and the reviews describe a charger.
Less suitable: A British bedroom, a rental, or any socket that takes a BS 1363 three-pin plug.

The Rekavin MKW-3 is a Type G charger plug at £6.37 with one USB-C port and one USB-A port, and the listing claims 20 W. It carries 4.4 from 3,421 amazon.co.uk ratings, a large sample next to the 5 W heads in this set. Reviewers describe a phone going from nearly empty to full in about an hour and a half, and one text uses it for a phone, an iPad and a Fitbit. The box line says no cable, so you use one you already own. A buyer found it got really hot, and another could not fast-charge a Samsung S22 on either port after trying several cables. One review also reported radio interference compared with Huawei and Samsung chargers. Some older texts in the sample describe a four-port unit, so treat those as a possible mix. It is the best value here when you want a stated 20 W USB-C plug under £7 and you will supply the cable.
Pros
- Type G on the attribute line, and the port count agrees at two
- 20 W claimed, with USB-C and USB-A, at £6.37
- 4.4 from 3,421 amazon.co.uk ratings
- Box line states that no cable is included
Cons
- Gets really hot in one UK review
- Did not fast-charge a Samsung S22 on either port in one test by a buyer
- One report of radio interference
- Some older review texts describe a four-port unit
Best for: A first USB-C phone plug under £7 when you already own a cable and can accept a shared or missed fast-charge claim.
Less suitable: A Samsung S22 owner who needs the stated fast charge on the first try, or anyone who must keep the 13 A socket free.

Our view
This TEYASI two-pack is £8.49 and Type G, the title says a 3-port plug while the field says 4, and the wattage field says 25 W while a bullet says 15 W at 3.1 A. The star line is 4.4 from 1,813 amazon.co.uk ratings. Reviewers use one for a hand fan and a phone, they like not taking extra 13 A sockets, and one buyer says all slots can be used together without overheating. Another found the plug loose in the wall and tight on a USB plug, and said the photos look better than the object. One of a pair did not work on arrival, and one buyer ordered a 2-port item and says a 4-port arrived. The wired-charging field says USB Type A, so do not assume a USB-C port. It is a spare multi-port pair if you check the body you receive, and you should skip it if the listing must agree with itself before you pay.
Pros
- Type G on the attribute line
- Two plugs at £8.49, with 4.4 from 1,813 ratings
- One reviewer used all slots together and reported no overheating
- Used for a phone and a small hand fan
Cons
- Title says 3-port and the field says 4
- 25 W in one field and 15 W at 3.1 A in a bullet
- Loose in the wall in one review, and one unit dead on arrival
- One buyer says a 4-port arrived after ordering a 2-port item
Best for: A spare pair of Type G multi-port USB-A plugs if you check the body against the title.
Less suitable: A USB-C phone, or a buyer who needs the port count and wattage to match on the page.

Our view
This two-pack is £6.79 for two Type G USB-A plugs, and the bullet states 5 V at 1 A. The star line is 4.4 from 710 amazon.co.uk ratings. Reviewers call the plugs small and neat, and they like the USB port on the bottom so the cable does not stick out. The same sample calls the charge incredibly slow on both plugs and on several cables, which matches the printed 5 W and still surprises people who read a charger plug as fast. The title and box say two items, while the number-of-items field says 4. The attribute block prints 9 V and 2.22 A against the 5 V / 1 A bullet, and the model code TYS-20WPD does not match a 5 W head. At a stated 50 g they suit a spare bedside or a bag if slow is acceptable. Skip them if a phone must gain a useful charge before you leave the house.
Pros
- Type G on the attribute line
- Two plugs at £6.79, with 4.4 from 710 ratings
- USB port on the bottom, which reviewers say keeps the cable from sticking out
- 5 V at 1 A is printed, so the slow rate is not hidden
Cons
- Reviewers call the charge incredibly slow
- Pack count disagrees: two in the title, 4 in the number-of-items field
- 9 V and 2.22 A conflict with the 5 V / 1 A bullet
- Model code TYS-20WPD does not match a 5 W head
Best for: A pair of spare overnight USB-A plugs when a slow 5 W charge is acceptable.
Less suitable: A morning top-up, a USB-C phone, or anyone who needs the pack count to agree on the page.

Our view
The TEYASI four-port is a Type G USB-A plug at £6.79, and the title claims 25 W written as 5 V at 5 A, with no USB-C port. The star line is 4.4 from 416 amazon.co.uk ratings. Short reviews say it feels solid and that four USB sockets on one plug save space, including in a caravan or lodge with few sockets. The output-current field says 3 A, which does not match the 5 A bullet, and the stated weight is 10 g, which is hard to reconcile with a four-port body. Two UK reviews say it tilts or falls out of the socket, and then the phones do not charge. Other reviewers call the charge very slow, which fits a 5 V-only plug with no PD profile. Use it only if every device still has a USB-A cable and the socket holds a top-heavy plug, and skip it if you need USB-C or a plug that stays seated.
Pros
- Type G, and the title and port field both say four USB ports
- £6.79 for four USB-A sockets on one plug
- 4.4 from 416 amazon.co.uk ratings
- Used in reviews where a caravan or lodge has few sockets
Cons
- No USB-C port, and no PD profile is stated
- 5 A in the bullet and 3 A in the output-current field
- Tilts or falls out of the socket in two UK reviews
- Reviewers call the charge very slow
Best for: Four older USB-A devices on one Type G plug, if the socket holds a top-heavy body.
Less suitable: USB-C phones, a fast morning charge, or a loose or worn socket.

The TEYASI single is the cheapest row in this set at £5.99, and the bullet states 5 V at 1 A, which is 5 W. Across 74 amazon.co.uk ratings the star line is 4.4, but the file holds 30 UK review texts and several describe a three-port plug, so they may not be about this one-port title. The attribute block also prints 9 V DC and 2.22 A, which conflicts with the 5 V / 1 A bullet, and there is no plug-type line at all. One reviewer had to reseat the cable and still saw a slow charge. Another said it stopped after about three months of light use, and a pair-buyer said both failed in under a month. At 50 g with a six-month warranty it is a small overnight head only if the object that arrives matches the single-port title. Skip it if you need USB-C, a stated Type G line, or reviews that clearly describe this plug.
Pros
- Lowest shelf price in the set at £5.99
- Bullet states 5 V at 1 A, so the slow rate is printed
- Ranked 29 in Mobile Phone Mains Chargers in this capture
- Stated weight of 50 g
Cons
- No plug-type line in the file
- 9 V and 2.22 A conflict with the 5 V / 1 A bullet
- Several UK texts describe a three-port plug on a one-port title
- Sampled failures within weeks or about three months
Best for: A spare 5 W overnight head if the plug that arrives is the single-port object in the title.
Less suitable: Anyone who needs USB-C, a printed Type G line, or a review sample that matches this listing.

Common questions
How many USB ports does the title claim?
One. The box line is a single plug. Several UK reviews describe a three-port plug instead.
What output does the bullet state?
5 V/1 A (5 W). The attribute block also prints 9 V DC and 2.22 A.
Is a Type G plug printed?
No plug-type line is in this file.
How we compared
For this comparison we read the twelve amazon.co.uk listings in this folder. The number on each row is that listing’s star line times 20, shown here on a ten-point scale. It is not a lab mark, a pin-dimension check, or a certificate that any plug meets BS 1363 or BS 8546. Price is not inside the score. It is used only to choose the best-value row. A listing conflict, a heat comment, a missing cable, or reviews that describe the wrong object stays in the written assessment.
1
Plug pattern
30%A British socket needs Type G. A Type A or Type B attribute, or a missing plug line, is recorded against the title rather than ignored.
2
Charger or plug-through
20%A charger plug covers the 13 A holes. A plug-through is the only form here that keeps a mains outlet as well as USB.
3
Port and wattage
25%5 V at 1 A is a slow charge. A fast-charge claim needs a stated PD or QC port, and a headline wattage is the shared total unless a port table says otherwise.
4
Listing agreement
15%Title, port count, pack size and plug type should describe the same object. Where they do not, the conflict stays visible.

USB plug adapter buying guide
Start with the socket you actually have, then the wattage you will use, then whether a cable is in the box. A title that says UK is not the same thing as a Type G line.
What is a USB plug adapter?
A USB plug adapter on a UK socket is not one product. A charger plug gives you USB and covers the 13 A holes. A plug-through keeps those outlets and adds USB ports. A travel block is for a socket abroad, and the pins that stick out decide whether it belongs in Britain or in Europe. People in this set are usually charging phones at a bedside, sharing a tight double socket, or packing for a holiday. For a British bedroom the pins must be Type G.
Best for
- Bedside charging when several phones can share one socket and a shared wattage
- A socket that must keep a 13 A plug as well as USB
Not ideal for
- A bathroom or outdoor socket, because no IP rating is printed
- A UK wall if the plug attribute says Type A or Type B
Mistakes to avoid
- 1
Reading 3,250 W as the USB output
On the LENCENT and the toomke that figure is the AC side of a 13 A outlet. The LENCENT USB budget is printed separately as 3.4 A total.
- 2
Expecting 5 W to fast-charge
5 V at 1 A is a slow overnight rate. A fast claim on these pages means USB-C PD or a stated QC port, and even then the headline wattage is often shared.
- 3
Trusting a travel title for the pin direction
The DAYEFORUN title, the Type G attribute and the UK reviews do not agree on whether a 13 A plug fits. Check which pins stick out before you pack it.
What to weigh up
Plug pattern and the 13 A hole
HighThe pins come first. UK mains are 230 V, and a household plug is BS 1363 with a BS 1362 fuse. If the attribute says Type A or Type B, or there is no plug line, leave the row until it matches the wall. Type G is printed on the LENCENT, the Rekavin plugs, the Saqykan, the Aioneus 40 W and several TEYASI rows. It is missing on the cheapest TEYASI single, Type A on the Aioneus 33 W, and Type B on the toomke.
Wattage, shared total and the cable
High5 V at 1 A is 5 W. That is the TEYASI single, the TEYASI two-pack and the Rekavin four-pack: an overnight trickle, not a fast charge, even if a model code looks like a 20 W part. Fast, on these pages, means USB-C PD or a stated QC port. The Rekavin 20 W plug is about £6.37 and the box says no cable. The Aioneus 40 W and the Saqykan 40 W name PD and Quick Charge. The Aioneus output line is 5 V at 3.1 A, so 40 W is a headline for the plug, not every port at once.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
A USB-C phone plug under £7
You already own a cable and you can cover the mains hole. The Rekavin 20 W USB-C plug is Type G, about £6.37, with one USB-C and one USB-A. Heat, a missed fast charge on a Samsung S22, and one radio-interference report stay on the card.
Several phones on one socket
You want more than one USB port and you can leave some of them empty when you want the charge cooler. The Aioneus 40 W four-port is Type G, about £9.99, and the title and port field agree. It does not keep a 13 A outlet, and the cable is not in the box.
Common questions about USB plug adapters
Which USB plug adapter is the top pick?
The top pick is the LENCENT double with USB, about £11.89. It keeps two 13 A outlets, 3,250 W, and adds three USB ports with a USB budget of 3.4 A total. The amazon.co.uk line is 4.7 from 671 ratings, and sampled reviews describe a firm fit. There is no IP rating and no BS number in the file. Choose it when a mains plug and USB must share one socket.
How much does a USB plug adapter cost?
In this amazon.co.uk set a 5 W head starts at about £5.99, and the 20 W Rekavin is about £6.37. Multi-port plugs around 25 W to 40 W sit near £8.49 to £9.99. The top of these twelve is about £10.99 to £14.88, for a 5 W four-pack, the LENCENT, the toomke and the DAYEFORUN two-pack. These are captured shelf prices, not a live promise.
What should I check before I buy a USB plug adapter?
Check the pins first. A British bedroom needs Type G, and a plug-in device for a UK domestic socket has to suit BS 1363, with a BS 1362 fuse on a standard plug. Then decide whether the 13 A hole must stay: a charger plug is USB only, and a plug-through keeps mains outlets. Read wattage as a shared total unless a port table splits it. No row here prints BS 1363 or BS 8546.
Can I use a Europe travel USB adapter in a UK socket?
Not until you know which pins stick out. The DAYEFORUN two-pack is titled for travel, the attribute line says Type G, and UK reviews disagree: one says it will not take a 13 A plug, and another describes a UK outlet. Europe is 230 V and 50 Hz, so a phone needs the right pins, not a converter. A UK-sold travel adaptor should meet BS 8546, and none of these listings prints that number.
Does 3,250 W mean the USB output?
No. On the LENCENT and the toomke, 3,250 W is the AC side of a stated 13 A outlet. The LENCENT USB budget is printed separately as 3.4 A total. A 20 W, 33 W or 40 W headline on a charger plug is the budget for the whole plug unless a table splits it. 5 V at 1 A is 5 W, a slow charge, not a fast one.
Can I use a USB plug adapter in a bathroom?
No IP rating is printed on any of these twelve files, so none is a bathroom or outdoor rating. Unplug on scorch marks, buzzing, a burning smell, or a plug that falls out. A fixed USB socket on a new circuit or in a bathroom is work for a competent electrician. That split is in USB wall socket or plug adapter.
When should I stop and call an electrician?
Call a competent person if the socket is already damaged or warm, if the consumer unit will not reset, or if you want a fixed USB socket on a new circuit or in a bathroom. Stop if an appliance needs an earth and you cannot tell whether the adaptor has one. A broken earth pin that jammed in an MK socket, reported on one Rekavin pack, is not something to force.
Our verdict
If a 13 A plug and USB devices must share one British socket, the LENCENT double with USB is the top pick: two outlets stated at 13 A, three USB ports, and a USB budget of 3.4 A total, at about £11.89. If you only need a phone and you already have a cable, the Rekavin 20 W USB-C plug is the best value at about £6.37, with the heat and missed-fast-charge notes left in the assessment. Rows whose plug attribute says Type A or Type B, or whose reviews disagree on pin direction, stay in the table so you can see the conflict. None of these listings was lab-tested, and none prints BS 1363 or BS 8546.
