Do you need a power adapter for South Korea?
It depends on the plugs you use at home. Where do you live?
South Korea uses plug types C, F. Plugs from the United States will not fit, so bring a plug adapter.
The voltage here is 220V, different from 120V at home. Check the label on each device. If it lists a range that includes 220V, such as 100-240V, a plug adapter is enough. If it does not, as with some hair dryers and curling irons, you would need a voltage converter, or leave it at home.

What the plugs look like
Type C: two round pins, often called the Europlug.
Type F: two round pins with earth clips on the sides, often called Schuko.
These are the main plug types. Sockets can vary between buildings, especially older ones. For the official list, see the IEC, World Plugs.
Good to know in South Korea
South Korea uses Type C and F plugs at 220V/60Hz. European plugs (Type C) work. US/UK/AU travelers need an adapter. Most hotels provide universal adapters on request.
Adapter or converter?
An adapter only changes the shape of the plug so it fits the socket. A converter also changes the voltage. Most phone, tablet and laptop chargers handle different voltages on their own, so for those you only need an adapter. Check the label on each charger for a range such as 100-240V.
What to bring
One adapter with several USB ports can charge your phone, tablet and earbuds together. Check that the one you choose fits plug types C, F.

Common questions
What is the difference between an adapter and a converter?
An adapter only changes the shape of the plug so it fits the socket. A converter also changes the voltage. Most phone and laptop chargers handle different voltages themselves, so they only need an adapter.
How do I know if my device can handle the voltage?
Look at the small print on the charger or the back of the device. If it lists a range that includes the voltage in South Korea, such as 100-240V, it will work with just a plug adapter. If it lists one number that does not match, you would need a converter.
Can I bring my hair dryer?
Hair dryers and other heating tools often work at only one voltage, so check the label first. If it does not cover the local voltage, using it can damage it or be unsafe. Many hotels have hair dryers, so it can be easier to leave yours at home.
Do I need one adapter per device?
No. One adapter with several USB ports can charge a phone, tablet and earbuds at once. Make sure it fits the plug type used where you are going.
