If you’re traveling or moving outside of your home country, you should be aware that the voltage may be different from the country you’re going to. It may work initially if you plug a 110V device into a 220V socket (common in the UK, Europe, and parts of Asia), but it will surely burn up eventually. Hence, voltage converters are needed.
You’ll learn about the different types of voltage converters and which one you’ll need to travel internationally in this article.
Types of Voltage Converters
Depending on the type of voltage converter, it converts the socket voltage to a higher or lower voltage to be compatible with your device. However, how do you figure out which converter to choose? Before we get to the actual list, let me explain how the different kinds of voltage converters work.
There are 3 types of voltage converters:
- Converters for step-down
- Converters for step-ups
- Step up and down converters
Step Down Converters
Step-down converters are the most common type of voltage converter used by travelers from the US. They are also known as universal adapters or converters, DC-to-DC converters, or buck converters. Keep in mind that step down converters can only decrease voltage, but not increase it voltage! As a result, step down converters are a good option for travelers from the US/Canada visiting Europe (and other higher voltage countries).
Step Up Converters
When a 220V device is plugged into a socket that has a lower voltage, e.g. a 110V socket, a step-up converter is used. Voltage converters of this type are required for Europeans and (many) Asians traveling to the US or Canada. If you are temporarily in the US and aren’t intending on purchasing any US devices that you will use in Europe (you will need another converter), a step up converter is a good option.
Step Up and Down Converters
The best converter for international travelers is the step up/down converter, as it allows the most flexibility. In the UK and EU, the voltage is typically 220V-240V, whereas in the US, it’s 110V (common). Essentially, you can plug any device purchased anywhere around the world (provided it supports the maximum wattage) into any socket. For expats or travelers, for example, who want to be able to charge their devices worldwide (US, UK/Europe, Australia, Asia, etc.) these are the best choices.
Voltage Converters Comparison Guide
You need to keep in mind the maximum wattage of your voltage converter after choosing the right category of converter. A typical universal travel adapter/converter has a maximum power rating of 250 watts, while a typical hair dryer uses between 1000 and 1875 watts. This means that while they are perfect to charge your gadgets while traveling (e.g. smartphone, laptop, camera…), they are not suitable for charging high-power appliances.
Travelers who need to charge their smartphones, laptops, and other gadgets overseas will find the first four voltage converters in this list useful. Whether you’re relocating abroad or need to charge high-powered appliances while traveling (e.g. a fridge, food processor, flat iron…), a heavy-duty voltage converter is essential, such as the Hyted Converter (for travel) or the Rockstone Power (for relocation).
With that being said, here are the best voltage converters for different uses.

FAQ on Voltage Converters
Choosing a voltage converter really depends on your specific situation: your home country (where your devices are from), the country you’re going to (are you traveling internationally or relocating? ), the number of devices you’d like to charge simultaneously, and the wattage of the devices. Our readers have asked many questions about voltage converters. We have answered the most commonly asked questions below.
Which voltage converter for a euro trip?
You’ll need a stepdown voltage converter if you’re from the US or Canada (220V to 110V voltage converter). We recommend the Bestek universal travel adapter choice, as it has USB and AC charging ports for up to 7 devices simultaneously.
What’s the difference between a step up and a step down converter?
In order to plug a 110V device into a 220-240V socket, step up converters are used. If you are traveling from Europe, the UK, etc. to the US, you’ll need a step up converter.
With a step-down converter, you can connect a 110V device to a 220-240V socket. Step down converters are required when traveling from the US to over 150 countries (many of which use 230V voltage).
What’s the power supply in the Netherlands?
The Netherlands uses the same power supply as the rest of the EU, which is 230V, or 50-60 hertz. If you are visiting the Netherlands from another European country (France, Spain, Germany…), you do not need to worry about plugging in your device. From the UK, travelers need a simple travel adapter since the sockets in continental Europe are different from those in the UK, but the voltage is the same. To use their devices in the Netherlands, travelers from the United States (and other low-voltage countries) need a step-down voltage converter.
What’s the difference between a travel adapter and a converter?
Travel adapters and converters differ by the voltage (current). Travel adapters are suitable when using the same voltage (e.g. Europe – UK) but different types of sockets. Using devices with different voltages (e.g. US – Europe/UK) requires a travel converter.
Are there travel adapters with USB ports?
Which travel adapter for the hair dryer?
Hair dryers aren’t suitable for portable voltage converters because they are high-power appliances. For those looking for a portable hair dryer adapter, the Hyted is a good option.
