You are packing for South Korea. Your phone charger, laptop, and hair dryer are ready—but will they work when you arrive?
Buying the wrong travel adapter is an easy mistake. An adapter changes the plug shape. It does not change the voltage. Here is how to check what you actually need before spending money.
The quick answer
South Korea uses 220V electricity at 60Hz and outlets with two round holes.
- Your device says INPUT: 100–240V: It accepts Korea’s voltage. If its plug does not fit, you need a suitable travel adapter.
- Your device says INPUT: 110–120V only: A plug adapter alone is not enough. Check that device’s manufacturer instructions before considering a voltage converter.
- You cannot find the input rating: Do not plug the device in until you have checked it.
Read the rating on the device or its own power supply. One charger’s rating does not tell you whether another appliance is safe to use.
Adapter or converter: which should you buy?
Phone or laptop charger: Does its INPUT range include 220V? If yes, choose a compatible plug adapter if the plug does not fit.
Hair dryer or styling tool: Is the appliance itself rated for 220V? If not, check its manual. Using an appliance available at your accommodation may be simpler.
Any 110–120V-only device: Check whether its manufacturer permits use with a suitable converter. Follow the requirements for that exact device before buying one.
The most important line is the INPUT rating. Electrical Safety First advises travelers to check the destination’s plug, voltage, and frequency, then check the rating plate on each appliance.
What to look for in an adapter for Korea
If your devices accept 220V but have U.S. plugs, look for an adapter advertised for South Korea and Type E/F outlets. Check the product’s plug type and electrical limits before ordering.
One available example is the TESSAN Type E/F Plug Adapter, 2 Pack. Its Amazon listing identifies it as a South Korea outlet adapter with USB ports and states that it does not convert voltage. It is an option only for devices that can use Korea’s electrical supply.

You do not have to buy this model. Compare its specifications with the devices you will pack, particularly if you need a grounded connection or plan to use more than one device.
Pay extra attention to hair dryers
A phone charger and a hair dryer may need different solutions. Check the label on the hair dryer itself.
If it is rated only for 110–120V, do not plug it into a Korean outlet using only an adapter. Before buying a converter, consult the hair dryer manufacturer’s instructions and check what your hotel or other accommodation provides. That may save you from packing equipment you do not need.
Your five-minute pre-trip checklist
- Put every device you plan to plug in on a table.
- Find INPUT on each device or its power supply.
- Confirm whether the listed voltage range includes 220V.
- Check the plug shape and choose an adapter suitable for Korean outlets.
- Check your accommodation’s amenities before packing a hair dryer.
The Korea Tourism Organization notes that travelers may be able to borrow or buy an adapter at a hotel front desk. Check with your particular accommodation if you plan to rely on one.
Choose the adapter after checking your devices. That one step makes the purchase simpler and helps you avoid bringing the wrong equipment.
