What adapter do I need for South Korea?

The type of power adapter, power converter or charger that you'll need when visiting South Korea all depend on the voltage and type of device that you're attempting to use in a South Korean power outlet. If you don't know what voltage your device can use then please read the section below about how can you tell if you have a single voltage or dual voltage device before going any further.

  • If you are travelling to South Korea from America then you will need to bring a power adapter to fit a US plug into a South Korean power outlet. Because the voltage is different in South Korea pack a power converter if your device or appliance isn't dual voltage.
  • If your device can run on 220 volts or is dual voltage and your plug fits in a South Korean power outlet then you can use it in South Korea.
  • If your device can run on 220 volts or is dual voltage but your plug won't fit in a South Korean power outlet then you will need to bring a suitable plug adapter for South Korea such a Type F plug adapter [3]. Please be aware that a plug adapter for South Korea (or power adapter) only changes the shape of the plug on your device to fit into a plug outlet found in South Korea, but isn't designed to change the voltage from 220 volts to another voltage.
  • If your device doesn't run on 220 volts and isn't dual voltage you will also need a power converter for South Korea to convert the voltage from 220 volts to the correct voltage on your device. You will still need to bring along a suitable plug adapter for South Korea if your power converter doesn't have the correct Type F plug adapter.
  • If you only want to bring one or more USB devices such as mobile phones or tablets then a USB travel power adapter will be more suited and it should work with any voltage, however ensure that you bring a USB travel adapter which has a Type F plug adapter otherwise you'll still need to use a suitable plug adapter for South Korea.

Warning: If your device won't handle 220 volts you run the risk of an electrical fire hazard, a blown fuse or damage to your device. Before attempting to use your device in South Korea please check the instruction manual first to ensure safe operation.

Also known as: electrical converter, electrical transformer, voltage converter, power transformer or voltage transformer.

What is the difference between a power adapter and a power converter for South Korea?

An expensive and heavy power converter [8] will convert the voltage of 220 volts from a South Korean power outlet to work with a non-220 volt device, however a more lightweight and smaller power adapter [7] (or plug adapter) changes the shape of the plug on your appliance to slot into a power outlet in South Korea.

Do I need a power converter for South Korea?

When you are travelling to South Korea from another region please ensure the device can be charged using a 220 volt power supply.

  • You will need a step down power converter [9] if you are travelling from a country that uses 100-120 volts and your device is incompatible with 220 volts. See the world power outlets guide to discover which voltage your country uses.
  • You don't need a power converter if you are already using either a 220 volt single voltage appliance or one that supports dual voltage.
  • Typically, electrical devices which are designed to use a lower voltage (for example 120 volts) and used in a 220 volt outlet run a risk of an electrical fire hazard, blowing a fuse or damage to your device unless you use a step down power converter [9].
  • You shouldn't need a power converter if you are attempting to recharge a smaller electrical device such as a tablet or cell phone as these are normally designed for international use and dual voltage, but please always check the device for dual voltage support first.
  • For powering high wattage appliances or generate heat (such as clothes irons and hair straighteners) then you will need to use a more expensive higher wattage heavy duty power converter [10].
  • Purchasing a smaller lightweight dual voltage travel appliance could be more practical and cost effective than carrying a much heavier power converter just to use your existing domestic appliance.
  • Read our guides on using clothes irons, curling wands, hair straighteners and blow dryers with a South Korean power outlet , along with advice on affordable dual voltage alternatives.

What is the difference between a transformer and a power converter?

Voltage converter

What is the difference between a transformer and a power converter?

Converters and transformers are both used to change one voltage to another, but this ambiguity can cause confusion as their purposes are different:

  • Power converters are designed for simple electrical appliances which typically generate heat or use motors such as clothes irons, shavers or hair dryers. Transformers are designed for more complex electronic items such as televisions or games consoles.
  • Buying a power converter is cheaper than buying a power transformer.
  • Power transformers are larger and heavier making them more suited for permanent residential use; for example an expat wishing to use an imported television would need to use a transformer for this purpose.
  • Power converters are more suitable for travellers wishing to bring domestic appliances abroad such as hair dryers or flat irons. However, it is more practical and cost effective to purchase a dual voltage appliance designed for travel rather than a heavier power converter.
  • Power converters are suitable for 2 pin ungrounded appliances, it could be harder to find a converter if you want to use a grounded 3 pin appliance.
  • Transformers can be used constantly however it is recommended that converters are used for no longer than a couple of hours at a time.
  • Shops may sell transformers under the name of converters, for the purposes this guide we will be referring to both converters and transformers as converters.

What voltage is used in South Korea?

South Korea uses 220 volts in their normal power outlets.

How can you tell if you have a dual voltage appliance?

Dual voltage hair straighteners

How can you tell if you have a dual voltage appliance?

The way to tell if your device is dual voltage is to look for numbers printed on the power plug or on the device itself, normally on the rear of the device or near to where the power cord goes. This location might depend on the make and model of your appliance and could also state in the instruction manual.

  • Single voltage devices could have a specific number - such as 220V.
  • Single voltage devices might also say a small voltage range (around 20 volts) with a dash to accomodate small voltage fluctuations - such as 100-120V.
  • Dual voltage devices will say a large voltage range separated with a slash - such as 110/240V.
