If you’re planning to travel outside the United States, you need a reliable travel adapter and power converter. Differences in international power grids means there are no universal standards for voltage, frequency, or plug types around the world. Depending on where you go and which devices you’re charging, you may need an adapter, a converter, or both. 

A travel adapter simply lets you plug into different outlets. A converter adjusts the voltage so the electrical current doesn’t overpower your device. Knowing when to use one over the other—or, in some cases, both at the same time—depends on a few factors. 

“Modern cell phones are able to detect the power output for the given power adapter they are plugged into,” says Logan Brown, the travel photographer and writer behind NomadPhotographer.com.  

For this reason, smartphones and other similar devices, like tablets and laptops, require just an adapter. However, devices with higher wattages, like hair dryers and curling irons, require a converter, unless they’re clearly labeled “dual-voltage.” 

“Power plugs in the United States are rated at 120V, while most countries overseas are 230V,” Brown explains. “If you plug in your 120V device into a simple adapter in the U.K., for example, it would be subjected to a full 230V and could, at minimum, damage your device, and at the worst, could be a fire or safety risk.” 

Investing in a quality adapter and converter now will save you headaches later. Scroll on to find top-rated options that will ensure devices and appliances are ready to go wherever you go. 

When shopping for a travel adapter and converter, look for versatility (enough plug types if you travel frequently) and solid performance reviews.   They should also be compact and built to last. We like a travel kit or bag to keep things tidy, but that may not be necessary if you don’t travel to many different countries. 

Why we like it: This versatile adapter kit is made for anyone who relies on multiple devices while they travel. It can charge up to seven devices at once and comes with multiple attachment plugs, making it compatible with outlets in North America, the United Kingdom, most of Europe, Australia, Japan, and more destinations. 

Kari LeMay, a blogger with AchieveYourBucketList.com, says that this kit has worked well in five continents and 16 countries and notes that the kit has a built-in surge protector. 

“Don’t look further. This is the one you want,” asserts one of the 21,000 Amazon reviews.

Keep in mind: The manufacturer makes it clear that this isn’t a voltage converter  and is best for plugging in devices like cell phones, e-readers, and tablets. It isn’t recommended for use with appliances that have high voltage requirements, like hair clippers, hair dryers, and curling irons. (For those, you may want to buy an additional charging device. See our converter pick below.)

When creating our list of contenders, we considered everything from size and packability to charging speed, performance safety, and more. 

• Third-party reviews: We combed through hundreds of reviews from customers who have used these devices firsthand and carefully weighed both their positive and negative experiences. 

• Expert advice: We consulted tech experts, travel writers, and other digital pros for product recommendations and additional insight. 

• Brand reputation: We considered products from proven market leaders that already have solid track records alongside newer brands that customers love. 

• Product features: We favored versatile products that checked multiple boxes, from a compact design and reliable performance to the ability to charge multiple devices at once.  

Determine which digital devices you’ll be packing  

Include a section in your packing list for digital devices, noting the type of output ports each requires. 

For instance, if you’re packing just a cellphone and a smartwatch, a basic travel adapter with a few compatible charging ports should suffice. However, if you’re also taking a laptop and an e-reader, you’ll need an adapter or converter that can charge multiple devices at once. 

Likewise, hair dryers, CPAP machines, and other devices that run on higher voltage will require a compatible voltage converter. When choosing one, look closely at the input/output, as well as the product details (paying attention to any specific brands) to ensure that you’re choosing one that’s truly compatible with your appliances. That may mean purchasing more than one charging accessory, but you’ll thank yourself later.  

Read up on the electrical requirements at your destination(s)     

Since voltage requirements and plug types differ from country to country, you’ll need to check that the adapter or converter you’re buying matches the outlets and power requirements at your destination. You can ask your travel outfitter, accommodations at your destination, or check REI’s helpful online guide. 

Frequent globetrotters may want to invest in a kit that comes with multiple plug attachments for different countries. 

Consider which features are most important to you 

According to Tom Payne, a UK-based technology writer with (Tech) for Travel who has tried many adapters and converters, a quality adapter doesn’t have to break the bank.  

“Most well-known brands are competitively priced and share many of the same features,” he says. “Those with a higher price tag tend to come with additional items you may not necessarily need, like a travel case for the travel adapter.” 

That said, Payne recommends choosing an adapter that gives you the most bang for your buck. 

“Worldwide travel adapters can charge multiple devices simultaneously through the main socket and a selection of USB ports,” he says. “So, try to find one that can handle as many devices as you plan to have with you.” 

Additionally, Payne suggests looking for newer models of adapters that have at least one USB-C port, which offer faster charging speeds.  

The same is true of adapters built on Gallium Nitrade (GaN), which should be listed in the product details. “This relatively new way of manufacturing adapters makes them smaller and lighter, more energy efficient, and keeps the adapter cooler when charging multiple devices,” says Payne.    

Review product safety markings 

“With any electronic purchase, make sure you check for appropriate manufacturing marks, which show the products have been tested and produced in a way that is safe to use,” says Sebastien Coell, a travel photographer and electrical engineer from the U.K. “In the U.S., these can be the MET Mark, UL mark, ETL Mark, or the FCC mark. In the EU the CE and FCC marks are used.” 

“These marks ensure the product has been produced according to safety standards set by government bodies,” he continues. 

Check for maximum wattage amounts  

When it comes to buying travel converters, Coell says to look at the maximum wattage the device can provide and make sure it’s slightly more than the highest wattage device you want to use.  

“This will ensure you won't overload the converter when in use,” he explains. 

Travel converter vs. adapter—what’s the difference?   

“The main difference between a travel converter and an adapter is voltage conversion,” explains Tom Payne. “A universal travel adapter changes the plug shape, so your device fits into foreign outlets, but, most importantly, it doesn’t convert the voltage.” 

A travel converter, on the other hand, does both. 

“You'll need a converter if you’re using a 110V-only appliance, such as a hair dryer or shaver in a 220V country,” says Payne. “Failure to get this right could fry your device if it’s plugged into the wrong voltage.” 

Are travel converters allowed in a carry-on bag? 

Yes. According to the Transportation Security Administration (TSA), travel converters are allowed in both carry-on bags and checked luggage.   

Do you need a voltage converter for cell phones?   

No. “Most cell phone chargers are smart and can run on voltages from all countries,” explains Coell. For this reason, you will only need a travel adapter, unless you’re packing other items that require a converter.
