Our Top Picks
Best Overall: Travel Ready AC Power Adapter
This U.K. power adapter is built to last, with heavy-duty high-quality construction that will endure plenty of jaunts to England, Scotland, and Northern Ireland. It’s able to charge two devices at the same time. The durability of its design — great for long stays in the United Kingdom — is aided by a lack of moving parts. The prongs don’t spring out of any central housing; instead, they’re affixed securely to the adapter to hold up against the wear and tear of travel, and the prongs fit snugly into the outlet without looseness or wobbling. Best of all, the main input receptacle can handle any type of plug, not just domestic ones, so if you have to buy a spare part elsewhere on your travels, you won’t have any issues charging it while you’re in the U.K. The second outlet, at the top of the adapter, accepts U.S. and European plugs.
Best USB Strip: Syncwire 4-Port USB Wall Charger
This USB strip is great for friends traveling together or for those who travel with their phones, tablet, and camera and prefer to charge all their devices at once. The plug is smart, too, taking an input of either 100v or 240v and then figuring out the correct current for each device so it charges as quickly as possible. It will also work at home, thanks to the U.S. plugs that come standard, and then you can add on the included U.K. and European chargers. It comes in black or white, so if you’re buying for you and your partner, each of you can keep your cords and gadgets separate. It’s built with overheating, overloading, and overcharging protection, so your devices are safe if you’re out and about. Plus, it weighs only 6.7 ounces, so it’s not too heavy in your carry-on or purse.
Best Converter Combo: BESTEK Universal Travel Adapter
The BESTEK Universal Travel Adapter will be a great companion both at home and abroad. It has three domestic outlets for use at home; for heading abroad, just unplug it and bring along the U.K. power adapter. The ports can charge up to seven devices at the same time. In addition to the outlets, it also has four USB slots. The setup also has a 110V voltage converter, so you’ll never worry about having to bring yet another gadget in your suitcase. Should you not need the converter, however, you can just bring the U.K. adapter and leave the rest of the kit at home. We also love the relatively low profile; it’s not too bulky or awkward to pack. Best of all, the product is protected with a 24-month warranty — and with over-current, over-loading, overheating, and short-circuiting protection.
Best Budget: PowerBright US to UK Travel Outlet Plug Adapter
If you just need a more inexpensive U.K. plug — and only one, versus a set of adapters — this one offers great value. At just 2.4 ounces, it doesn’t add a lot of weight to suitcases or bags, either, and you can use both two- and three-prong U.S. plugs in its input receptacle. Like with other Type G plugs, this won’t just work in the U.K., but also in some other countries in Africa, the Middle East, and Asia as well, so once you’re back, keep it on hand for future travels. Do keep in mind that it won’t switch voltages automatically, so if you’re using it with devices like hair dryers or curling irons, make sure it’s compatible before plugging it in — otherwise you might get a spark or two. (We suggest getting a travel-size hairdryer to be on the safe side.) The adapter comes with a one-year parts and labor warranty, too, so in case something doesn’t work right, you can get a replacement.
Best Portable: Mu Portable International Charger
If packing space is tight with airline restrictions on suitcase sizes and weights, Mu’s portable charger is branded the world’s thinnest portable charger. It’s lightweight and streamlined to tuck easily into a purse or even pocket with no more bulk than a standard phone charger. It measures about 3 x 2 inches and weighs only 0.16 ounces. The design, which won the British Design of the Year award, is truly innovative; the charger has two USB ports for a couple’s phones or a tablet and phone, and then you just slide the interchangeable plug heads on and off. It comes with one for the U.K., one for Europe, and one for the U.S., so you can use it when you’re back home too. With plenty of light travel devices using USB devices, including cameras, phones, and tablets, this will help you stay connected and powered up without the bulk of more old-school adapters.
Best Set: BESTEK Worldwide Travel Plug Adapter Set
Adapter sets are great for travelers going to the U.K. but also have their sights set on further foreign travel — and don’t want the bulk of having a chunky, heavy universal adapter in their bag. They often offer the best value for money, too. There’s no voltage converter, but with most modern technology, you won’t need that. This set comes with plugs for the U.K., Italy, India, Australia, Hong Kong, Japan, Northern Europe, and Israel. Although each prong set is specific to a country, each adapter does have a universal input, so if you have to pick up a gadget in France, like a new camera charger, you can still use it and plug it into the U.K. power adapter on your next trip. Although they might look basic, these power adapters are also very well constructed, with connections that are solid and trustworthy.
Best Universal: Haozi Universal Travel Adapter
If you're heading to the U.K. often but also pop around to different continents or countries, a universal adapter might be the right choice for you. It comes in a sleeker black or more conspicuous electric blue with black sides, which we actually prefer for standing out in hotel room outlets when it’s time to pack. You’ll be able to travel to most countries with this charger too: just slide the buttons on the side to unlock (and then lock in place) the correct prongs for wherever you find yourself, including the EU and Australia. The main receptacle is also universal, should you ever pick up a spare part or new electronic device while you’re abroad — and you can unlock U.S. prongs to charge the new device when you’re back at home. It’s also certified for safety so devices don’t overheat, and there are safety shutters built in so people don’t get a shock if they touch a live part.
What to Look for in a Power Adapter for UK Travel
Weight Power adapters can be surprisingly heavy so consider how many you really need to take on a trip. Are you willing to take turns with the devices you’re charging or do you need one for each? Carrying multiple can sneak up on you and really add weight to your checked luggage or carry-on.
Cost If you’re tethered to your electronics for work or just getting around town, don’t risk a cheap adapter that’s going to spark or otherwise fizzle out after a couple of uses. Use our guide to find one that’s built to last, even after a few years of keeping you connected.
Voltage conversion Most electronic gadgets and devices these days come with built-in automatic voltage conversion—but double-check before plugging a device into your adapter. Although converters do exist, they can be pricey.
