Buying guide for best international plug adapters

Last Updated August 2019

Ever try to plug your American hair dryer in at a hotel room in, say, Paris? If so, you probably recall spending that morning with wet hair. When you are traveling internationally, outlets can vary in their voltage and type. But with the right international plug adapter, you can have access to power anywhere.

With 14 different types of sockets around the world, its crucial that the adapter you choose is compatible with the outlets at your destination. Some socket types are widespread and used across several continents while others are specific to smaller regions or used only in a few countries. If you want to charge multiple devices at once, additional features like multiple outlets or USB ports are required.

With factors like voltage and surge protection, there is a lot to think about — and little wiggle room — when shopping for an international plug adapter. To learn more, check out our in-depth shopping guide. If you’re ready to buy, consider one of our recommended products for your next trip.

Most adapters are not voltage converters — they will allow you to plug your devices in by providing the right pin layout, but they won’t convert the voltage to protect your device.

Key considerations

Compatibility

Determining the socket types in the regions you are traveling to is the first step when searching for an adapter. There are 14 socket types (or plug types) recognized by the IEC (International Electrotechnical Commission). The following are the most popular plug/socket types, but there are many more, some of which are only used in one or two countries.

  • Types A and B are widespread in North America and in parts of South America, Africa, and Asia.
  • Type C is used in most of Europe, Africa, South America, and Asia.
  • Type F is used in parts of Europe, Africa, and Asia.


Each socket type receives pins — the metal prongs of a plug — in a different way and sometimes receives a different number of pins. Most plug adapters have several switches that extend different plug types, so you’ll be covered in a number of countries. Some adapters have only a single plug type and a single outlet type on the opposite side. Research the area you are traveling to carefully to determine what socket types are common at your destination. You can also contact your hotels and ask what types of sockets they offer.

Compact and versatile

With support for more than 150 countries, this adapter packs a punch with it small size and three-device charging capability. Though it does not convert voltage, customers find this adapter safe and easy to use.

Voltage conversion

While an international plug adapter will allow your device to draw power from a socket, it won’t usually convert the voltage of the socket.

Sockets in Canada and the U.S. typically output 110 to 127 volts, and most North American appliances and devices are designed to draw energy safely from these sockets. Other parts of the world have sockets that output 220 to 240 volts. Many devices are dual-voltage — meaning that they can accept either voltage range safely.

Before you travel, check the voltage of your appliances and devices. If you plug a device into a socket that puts out a higher voltage, your device will most likely break if it doesn’t automatically turn off when it senses the incorrect voltage. If the device requires a higher voltage than the socket can provide, the device may not function properly or may not turn on at all.

If your devices won’t work where you’re taking them, you will need an appropriate voltage converter — a separate accessory from an international plug adapter. Some international plug adapters double as voltage converters, but these are usually significantly more expensive.

Output

You should have an idea of how many devices you will need to power or charge at a time. Most adapters can accommodate one Type A plug and one or two USB devices, often at the same time. If you need to power multiple AC devices, you may need an additional adapter. Some models may have additional Type A outlets, so you can power two to four devices at once.

EXPERT TIP

If you are unsure of whether your adapter will work where you are traveling, the safest option is to call ahead to your hotel.

Features

Safety shutters and surge protectors

Many international plug adapters have safety shutters, which prevent direct contact with the plugs to reduce the chance of electric shock. You should also consider adapters with built-in surge protectors to keep valuable devices like phones and computers safe while plugged in.

Size

Packing light can be crucial when you’re traveling. If you have limited space, look for a compact international plug adapter. In many cases, this means looking for one that is limited in its plugs. Most international plug adapters are fairly compact, often under 8 inches in length and height.

Take note of the voltage of your devices before you travel, as they may not be compatible with the voltage of the outlets at your destination.

International plug adapter prices

Inexpensive: Basic adapters for $5 to $10 usually include several pieces. In a sense, they’re not truly “international” unless you bring all of the adapters with you. However, you can bring only the necessary adapters to save space in your luggage.

Mid-range: For $10 to $20, these adapters usually include several plug types and use the more standard block model with switches for each plug. Some adapters in this range may also be surge protectors and include USB ports.

Expensive: For $20 to $40 are adapters with a wide variety of plugs and sometimes several Type A outlets. If you need to power multiple devices, adapters in this range may be your best option.

DID YOU KNOW?

Plugging a power strip into a plug adapter is an easy way to power several devices at once.

Tips

  • Look for an adapter that includes the foreign plug on one side and your country’s socket on the opposite side, as this makes for a convenient way to plug in your devices.
  • If you are staying at a hotel, you should call ahead to see if they have universal outlets.
  • While airports may have the adapter you are looking for, you should buy your adapter before you leave so you don’t need to spend time hunting for the perfect adapter mid-journey.
  • Some international plug adapters are prone to falling out of the socket due to the weight of the adapter. Read customer reviews to find out whether this is an issue with the model you are considering.

Simple and budget-friendly

Its five adapters limit this set to specific regions, but this adapter set is straightforward and comes with a convenient carrying case. With an affordable price and lifetime warranty, it’s a great option for those on a budget.

Other products we considered

One international plug adapter that doubles as a voltage converter is the DOACE Travel Voltage Converter, which is specifically designed to work with hair dryers. This converter includes several adapters and works with 110- to 127-volt devices as well as 220- to 240-volt devices. You’ll also love the included travel bag, which keeps everything in one place. A similar model is the FOVAL Power Step-Down Voltage Converter. While it also offers a limited number of adapters, its four USB ports and two Type A sockets are excellent. It also includes a five-foot power cable, giving you flexibility while powering your devices.

Hair dryers can pose one of the greatest challenges when searching for a compatible outlet abroad. You may want to leave your hair dryer at home and ask your hotel if they have a hair dryer available.

FAQ

Q. Why are there different types of wall outlets in the first place?
A.
When electricity became commonplace in homes, outlets were developed independently around the world, and standardization has presented too great a challenge.

Q. Can all adapters fit Type A three-pin plugs?
A.
No. In fact, many are missing the third hole, which houses the round earth plug that grounds the wire. If you have a device with a three-pin plug, be sure to purchase a compatible adapter.

Q. Is it safe to leave an adapter plugged into a socket when nothing is plugged into it?
A.
You should always unplug your adapter when it is not in use.
