![]() All the adapters we tested are about 2 inches wide and 2⅛ inches deep this one is 2¾ inches tall, which is as small as we’ve found for a universal adapter. The Tessan is otherwise similar to everything else out there, with Type A, I, G and C plugs (see the “How we picked” section below for more detail on the different plug styles). You’ll want one of our other picks if you’ll be charging a laptop or tablet. Especially if you’ll be charging overnight, you’re not likely to notice you’re not getting the absolute maximum speed. You can get faster charging speeds from other adapters, and many devices will benefit from them (the iPhone 12 and later charge at up to 20 watts, for example), but the difference isn’t so big that we recommend paying more for it. That’ll charge most modern phones a bit slower than their maximum rate, but the speed is more than sufficient for devices with smaller batteries including fitness trackers or headphones.Įach of the three oval-shaped USB-C ports allow for 15-watt (5 volts at 3 amps) charging. There are two USB-A ports-the rectangular kind that’s becoming less common these days-both of which support 12-watt (5 volts at 2.5 amps) charging. Tessan’s adapter has five total, the most available on any competitor, with a total combined power output of 28 watts. The number, style and power outputs of USB ports is the biggest differentiating factor in this category. For about the price of a book at an airport newsstand, you get a well-built device that will work pretty much anywhere in the world, with a great selection of both USB-A and USB-C ports for charging all your gear. Tessan’s International Plug Adapter is the best of these accessories. Many now have a selection of USB ports as well, and these models are so prevalent that you shouldn’t buy an adapter without them. International travel power adapters all look pretty much the same: They are a plastic block with a face-like array of outlets to accept plugs from around the world on the front, and sliders along one side that push out the appropriate prongs for the country in which you want to charge. Slower charging to more power-hungry devices.This power adapter has a great selection of USB-A and USB-C ports in a compact package for a low price. Best travel power adapter for large laptops.Best travel power adapter for laptops and tablets.If you travel with a laptop and don’t want to pack a stand-alone charger, choose either Zendure’s Passport III or the OneAdaptr OneWorld100. Our top pick in the category is the Tessan International Plug Adapter, followed closely by Epicka’s International Travel Adapter. The best of them have multiple USB ports so you don’t need to pack an additional charger. “Its only purpose is to mechanically adapt your plug to that of the country you are visiting,” says Bartley, who holds a master’s degree in electrical engineering. As Ryan Bartley, vice president of business development and marketing at RedSky Engineering in Spanish Fork, Utah, explains, an adapter is a very simple device. International power adapters let you plug in U.S.-style prongs no matter where you are. Thankfully, there are a number of products that offer a solution to both issues. Many countries use different power outlets than the U.S., meaning you’re going to need an adapter to plug anything in. Bear in mind that this may limit where you can use them – the US and EU have both 2-pin and 3-pin sockets, so your 3-pin plug simply won’t fit into some sockets, and you might wish you’d risked it with a 2-pin model.International travel usually means packing gear and gadgets that have to be charged during the trip: a phone, power bank, headphones, even a laptop. While 3-pin plugs are the standard in the UK, elsewhere in the world they’re used less often or not at all.Įarthing helps to protect you and your gadgets from electric shock, so you may prefer to opt for 3-pin adapters, which offer an extra level of protection. One thing to look out for in travel adapters is whether or not they support earth pins. Unfortunately, there’s nothing a travel adapter can do about that, as they don’t convert voltage. For the most part, this isn’t an issue, but it may mean that some devices will charge more slowly than you’re used to, and some of the most power-intensive might not work at all if they can’t draw sufficient power from the mains to run. US sockets only run at 120V, while Japan offers an even skimpier 110V. UK plugs use 220-240V, which is conveniently what you’ll find across Europe and Australia.
