South Korean power outlet

What adapter do I need for South Korea?

Use a Type F plug adapter [3] for South Korea if the plug you intend on using won't fit into a South Korean power outlet.

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're unclear about 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 first.

  • 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 doesn'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 recharge one or more USB devices such as a mobile phone or tablet then a USB travel power adapter will be more suited and it should work with any voltage, however ensure that you choose to 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.
  • Increased use of a mobile phone during a vacation to South Korea can create an extra demand on the battery, we suggest bringing a power bank [4] if you need to recharge your phone whilst visiting an unfamiliar country.

Warning: If your device won't handle the 220 volts used in South Korea you run the potential risk of a blown fuse, damage to your device or even an electrical fire hazard. Prior to using your device in South Korea read the instruction manual to ensure safe operation.

Do I need a portable charger for South Korea?

A power bank

Do I need a portable charger for South Korea?

Even though electrical outages in South Korea aren't common and power is available to the entire population, visitors should still bring a power bank to recharge mobile phones and other USB powered devices.

  • The dependence on mobile phones for some people is high and the thought of being without a phone can cause anxiety, especially when being needed abroad. During a trip to South Korea increased reliance on cell phones for storing itineraries, taking photos, social network sharing, getting directions and streaming videos will drain the batteries excessively. A flat smart phone battery could potentially leave you without enough power to make emergency calls or being able to use satellite navigation to return back to your accommodation or hotel.
  • Using a portable charger [4] in South Korea lowers the risk as it allows you to keep your mobile phone powered on the move.
  • A typical 10,000mAh portable charger [4] can store enough energy to cover around 3 full charges while a 20,000mAh portable charger [14] should keep an average cell phone charged for roughly seven days depending on the model of phone and usage. The mAh rating (or milli ampere-hours) describes the capacity of the battery giving an indication of how many charges the power bank can do, therefore a higher value is more suitable for travellers.
  • Should you need to charge your laptop with a power bank in South Korea and your laptop it supports USB-C charging then use a portable charger for a laptop [15] marked with PD (power delivery) which supplies 20 Wh or more.
  • Before travelling be aware that some airlines prohibit portable chargers on an aircraft with more than 100 Wh of power and must be kept in carry-on luggage only so we recommended checking ahead with the airline first.
  • Small consumer power banks aren't powerful enough for high wattage items, although a rechargeable hair dryer [12] or gas hair straighteners [13] are designed for travelling.
Will a solar charger work in South Korea?

A solar backpack recharging

Will a solar charger work in South Korea?

The climate in South Korea might be suitable for a solar power bank [17] but is likely to take time to recharge. Because of the smaller surface area of the cells a solar power bank will need to be kept in powerful daylight for a long period of time to provide enough energy for a single charge, and this might prove difficult to repeatedly pack and unpack a solar power bank then wait whilst it recharges between cloud cover.

  • Instead, the bigger durable solar cells found on a solar backpack [16] give the bag the ability to generate more power within a faster period of time.
  • A phone that is directly plugged into the USB charging port of a backpack should trickle charge the battery during sunny periods in South Korea, but might prove inconvenient to have a phone constantly tethered in the bag during the day should it be needed frequently. A power bank [4] plugged in a solar backpack can be constantly topped up inside the bag during sunlight, afterwards the phone can be recharged using the power bank at any time without sunshine.
  • A solar bag that is suitable for South Korea should have a solar cell efficiency of 22% or more, can generate a minimum of 6 watts of power and includes a 10,000mAH power bank or greater.
  • Solar bags are available in backpack, messenger and rucksack styles making them ideal for travel, work and domestic use.
  • Unlike normal solid solar panels, the flexible and durable solar cells used in solar powered bags have been built to survive bending and scratches.

Why use a travel USB charger for South Korea?

  • Typically travel USB chargers include multiple USB charger ports, this means that you now only need to bring a single charger to charge all your devices. Instead of bringing 4 separate power chargers it becomes only necessary to pack one 4 port USB wall charger and power up to 4 individual devices, thereby reducing the weight and size of your luggage.
  • Travel USB chargers include interchangeable plug heads for different power outlet types making them perfect if travelling across multiple countries across Asia which are likely to use a different outlet to South Korea.
  • Good chargers are compact, rugged and lightweight - ideal for rigors of travel instead of than risking packing a domestic charger which could be impossible to repair or replace in South Korea.
  • USB travel chargers can accept both the 220 volts used in South Korea power outlets and different voltage standards across the world.
  • There is a chance that accommodation or hotel rooms in South Korea might only have a single wall outlet, by using a travel charger with multiple USB ports means you can share out the single power supply with family or other traveler rather than waiting to charge one device at a time.
  • Due to their versatile nature a travel USB charger takes the uncertainty out of visiting any unknown country as they are guaranteed to work almost anywhere in the world.
  • Power outlets found in airports can be sparse and the demand for charging multiple cell phones and tablets before a flight can be high, so a USB charger with multiple ports and the ability to charge quickly is ideal.
  • Some countries power grids are unstable, a travel USB charger allows for unexpected spikes and will help prevent damage to any devices attached to it. Attempting to repair an overloaded cell phone or tablet in South Korea could prove to be inconvenient and expensive.

Power converters for South Korea

What does a power converter for a South Korean power outlet do?

A power converter enables you to use a 100, 110 or 120 volt electrical appliance with a 220 volt South Korean power outlet.

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?

A small, cheap and lightweight power adapter (or plug adapter) will change the shape of the plug on your appliance to fit into a power outlet found in South Korea, but a heavier and more expensive power converter [19] transforms a 220 volt South Korean power outlet to work with a non-220 volt device.

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 [10] 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 [10].
  • 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 [20].
  • 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.

Do I need a power converter for South Korea if I'm visiting from the US?

The voltage from a plug outlet in South Korea is different to a 110 volt US outlet so use a step down power converter if your charger or appliance isn't dual voltage.

What kind of converter do I need for South Korea?

You will need to buy a step down power converter [10] which allows you to use any 100, 110 or 120 volt appliance in a 220 volt South Korean power outlet.

How to convert 220 volts to 110 volts

  1. Use a step down power converter [10] to allow you to use a 110 or 120 volt appliance with a 220 volt South Korean power outlet.
  2. If the power converter doesn't include the correct shaped plug then it will also be necessary to plug in the power cord from the power converter into a power adapter for South Korea before plugging that into a South Korean power outlet.
  3. Some power converters include the ability to perform both step up and step down voltage conversions, therefore it may be necessary to manually switch the converter to output the voltage to the 110-120 volt range.
  4. Plug your appliance into the converter and turn the power on, your 110-120 volt appliance can now be used with a 220 volt South Korean power outlet.
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.

Key to electrical adapter comparison

  1. Compatible number of countries based on data from the International Electrotechnical Commission World Plugs page (cited November 2018).
  2. Assuming only a single plug adapter from the plug adapter set will be used at any one time in a compatible location.
  3. Depending on if the power strip supports voltage conversion for low wattage items. All travel power strips tested do not convert voltage for high wattage appliances.
  4. Including the device itself, any supplied plug heads and power cords.
  5. Some travel power strips featuring less AC outlets may be small and lightweight enough to be suitable for hand luggage.
  6. Number of items if bringing an entire set of plug adapters for use in multiple locations to cover all eventualities (unless bringing only the necessary single plug adapter).

What type of adapter do you need for South Korea?

Deciding which type of electrical adapter you need for South Korea

The type of plug adapter or power converter which is best to bring to South Korea is dependant on various requirements. Prior to deciding which one to use we recommend using this checklist:

What types of devices do you want to charge with a South Korean power outlet?

A USB powered phone

What types of devices do you want to charge with a South Korean power outlet?

  • There are 3 types of electrical items:
    • Low wattage electronic devices which can be plugged into a power outlet - for example a laptop.
    • High wattage electrical appliances which can be plugged into an electrical outlet - for example clothes irons and hair dryers.
    • USB devices which plug into a USB port - for example mobile phones or tablets.
  • Should you only want to bring along just USB powered devices to South Korea then a travel USB charger is ideal as you'll only need to bring one compact charger with some appropriate existing USB charging cables.
  • Travel power strips are built for providing power and converting voltage for several low wattage devices (such as cameras), but won't work with high wattage appliances (such as hair straighteners) which need voltage conversion.
How many electrical items will you be taking to South Korea?

How many electrical items are you packing

How many electrical items will you be taking to South Korea?

  • List all the electronic you intended on packing for South Korea (including cell phones, tablets, laptops, eReaders, curling irons and hair dryers).
    • Allow for more devices in the future. Do you intend on buying a new tablet computer next year for example?
    • There is a growing amount of smaller rechargeable electronics such as electric shavers which utilise USB charging as their power source. Therefore next time you buy a new device it could need a USB power adapter so please ensure your travel adapter has enough spare ports to power these additional devices too.
  • Will you be travelling with a partner who might need to charge their devices as well?

Will your devices work with 220 volt power outlets?

Will you only be charging USB devices?

Will you only bring USB items

Will you only be charging USB devices?

  • If you intend to pack USB powered electronics such as mobile phones or tablet computers for South Korea then we suggest just packing a travel USB wall charger.
  • If you only use a simple power plug adapter you'll still need to use your domestic USB power charger as well.
How many wall outlets will be available when you arrive in South Korea?

Are multiple outlets available

How many wall outlets will be available when you arrive in South Korea?

  • Your hotel might have only one wall outlet, this will present a problem when charging batteries of multiple items such as phones, tablet computers and cameras overnight as you will only be able to recharge a single device at a time then have to continually swap after each device has charged.
  • If you want to charge multiple devices simultaneously then we suggest packing either a travel USB wall charger or a travel power strip that can power multiple USB ports and outlets.

How much can you afford to pay?

  • Basic power adapters start from $7 which powers one single device in only one single country (providing that works with 220 volts or is dual voltage) but paying around $20 allows you to charge more than one device at once and be able to bring them to various different countries.

Do you plan on visiting countries other than South Korea?

  • A simple power adapter will only typically operate in a single country, therefore if you are visiting multiple countries then you may need to bring additional power adapters which can add to the weight you have to bring.
  • Alternatively, a travel USB wall charger or universal travel adapter is designed for going to multiple countries due to the interchangeable head system.

Are you intending on visiting anywhere else abroad in the future?

Are you only bringing hand luggage to South Korea?

Are you only using hand luggage

Are you only bringing hand luggage to South Korea?

Are you flying long haul to get to South Korea?

Using a phone after a long haul flight

Are you flying long haul to get to South Korea?

  • If you're taking a long journey to get to South Korea it's worth thinking about packing an charger which is perfect for airports that works in different outlet types, one that can be carried in hand luggage and can be used to quickly power tablets and phones.
  • Not all flights have power outlets so we recommend using a portable charger [4] for recharging on the go. When you land you could need to rely on a cell phone to make a telephone call, reading emails , using mapping to find a hotel or reading your itinerary; so ensure that your phone will have enough battery power left.

Would you like to use your charger when returning to America?

Are you visiting another country with reliable access to electrical power?

  • The power in South Korea is generally stable but if you need to go to another country you might need an adapter which offers protection to your appliances. Electricty will sporadically fluctuate in some countries and this can potentially cause damage to your devices, so it is advisable to use an adapter which offers surge protection such as a travel power strip.
  • Be prepared for power cuts and limited electrical coverage by using a solar backpack [16] and portable charger [4].
