Korea Plug Type 2026: Adapters, 220 V and What Your Devices Need

You land at Incheon, check into your hotel, and your phone is on 4%. You pull out your charger and it does not fit. This happens to a lot of first-time visitors, and it is easy to avoid.

Here is the short answer: Korea uses Type C and Type F plugs, the round two-pin plugs you see in Germany and most of Europe, at 220 volts and 60 Hz. If you come from the US, UK, Australia or Japan, you need an adapter. Most phone and laptop chargers work fine. Some hair tools do not.

Checked on October 25, 2026. This guide is about plugs and voltage. Check the label on your own devices before you plug them in.

Korea plug type and voltage

Korean sockets are round and set into the wall. Type F plugs, with metal clips on the sides, and slimmer Type C plugs both fit. Newer apartments and hotels almost all use the grounded Type F socket.

You may still find an old two-flat-pin socket in some old buildings. Do not plan on it. Bring a C or F adapter.

Do you need an adapter?

If you come from continental Europe, your plugs fit. Everyone else needs an adapter. US travelers with flat-pin chargers notice this first.

Adapter or converter? Check the label

An adapter only changes the shape of the plug. A converter changes the voltage. They are not the same thing.

Look at the small print on your charger. If it says INPUT: 100-240V, it works in Korea with a plain adapter. That covers almost every phone charger, laptop charger, camera battery charger and modern electric toothbrush.

If it says 110V or 120V only, plugging it into a Korean socket can burn it out. That is often true of hair straighteners, curling irons and hair dryers from North America and Japan. Buy a cheap dual-voltage one, or borrow the hotel’s dryer. Most Korean hotels and guesthouses have one in the room.

The 60 Hz frequency is the same as in the US, so clocks and small motors from North America behave normally. Europeans can ignore it too; chargers do not care.

Where to get an adapter in Korea

The easiest option is to ask at the front desk. Many Seoul hotels keep a box of adapters for guests. If they run out, Daiso sells simple adapters for a few thousand won, and there is a Daiso near almost every subway station in Seoul. Convenience stores like GS25 and CU sometimes carry them for a bit more.

If you are carrying a laptop, phone, watch and camera, bring one adapter plus a multi-port USB charger. Many guesthouses have only two sockets, and one is usually behind the bed.

Power banks on flights in Korea

Korean airlines tightened the rules after a cabin fire in January 2025. Since March 1, 2025, power banks on Korean airlines must not go in the overhead bin. Put them in a plastic bag or tape over the ports, and keep them with you.

In January 2026, Korean Air and four group airlines (Asiana, Jin Air, Air Busan and Air Seoul) also banned using power banks during the flight. This matters on domestic hops too, like Seoul to Jeju from Gimpo Airport.

Staying charged on the go

Your phone will work harder in Korea than at home. You use Naver Map or KakaoMap for directions, because Google Maps does not give full walking and transit directions here, plus translation and a payment app. All of that needs data and battery. See our Naver Map guide.

A Korea eSIM is the easiest way to stay online. Set it up before you fly so it works when you land.

Cafes are your friend. Most chain cafes have sockets at the window counters, and nobody minds if you charge while you drink your coffee. Subway stations and Incheon Airport also have charging spots.

If you need a card to pay and a place to keep cash, a prepaid travel card like WOWPASS also works as a T-money card for transport.

Checklist

• Pack one Type C or F adapter per two devices, or one adapter plus a USB hub charger
• Read the INPUT line on every charger: 100-240V is fine
• Leave 110V-only hair tools at home, or bring a dual-voltage one
• Keep power banks in your carry-on with taped ports, never in the overhead bin
• Set up your eSIM before you fly so you land with data

FAQ

What plug type does South Korea use?

Type C and Type F, both with two round pins, the same shape used in most of continental Europe.

What is the voltage in Korea?

220 volts at 60 Hz. Devices labeled 100-240V work with just a plug adapter.

Do Americans need an adapter in Korea?

Yes. US flat-pin plugs do not fit Korean sockets. Most phone and laptop chargers only need an adapter, but check hair tools for 110V-only labels.

Can I buy a plug adapter in Korea?

Yes. Ask your hotel first. Daiso sells simple adapters for a few thousand won, and convenience stores and Incheon Airport shops also carry them.

Will my hair dryer work in Korea?

Only if it says 100-240V or 220V. A 110V-only dryer can burn out. Most hotels provide a dryer in the room.

The short version

Korea uses round two-pin Type C and F plugs at 220 V. Bring an adapter unless you come from continental Europe, check that chargers say 100-240V, and leave 110V-only hair tools at home. Your hotel probably has a spare adapter, and Daiso has cheap ones. For more first-trip basics, see our T-money guide and money exchange guide.
