For Korea, check both your plug and your charger's input label before packing. A plug that fits does not establish that the appliance can use the local electricity supply. Korea Tourism Organization lists the standard supply as 220V, 60Hz, with sockets that have two round holes. Your equipment still needs its own compatibility check.
This guide is a packing workflow for visitors bringing phones, laptops, cameras and personal appliances. Keep the wider trip tasks in our South Korea first-trip checklist beside it.

Start with a three-question check
| Question | Where to look | What to record |
| Can the power supply accept Korea's electricity? | The appliance or external power adapter's rating plate and manual. | Input voltage and frequency. |
| Will the plug connect properly? | The actual plug and the travel adapter's destination instructions. | Supported plug/socket arrangement and any earth connection requirement. |
| Is this the right adapter for this appliance? | The adapter's instructions and maximum rating. | Permitted load and any equipment restrictions. |
Make one row in your own packing note for each item. “Phone charger” and “hair dryer” belong on separate rows even if both came from the same country. Photograph the labels clearly enough to read later; an unreadable photograph is a reminder to check again, rather than an answer.
1. Read INPUT, then find the manufacturer's instructions
The INPUT line describes the electricity a power supply accepts. A range that includes 220V and a frequency marking that includes 60Hz are relevant checks. The USB output printed elsewhere on a charger answers a different question: what it supplies to the connected device.
Electrical Safety First's overseas travel guidance explains dual-voltage rating plates and advises checking with the manufacturer when compatibility is uncertain. If a switch selects the input voltage, follow that exact product's instructions. Do not infer automatic switching from a different model or a similar-looking charger.
Use the model number when asking support. A useful message is: “I have model ___, bought in ___; its input label says ___. May I use it on 220V, 60Hz in South Korea, and what adapter is approved?” This gives support something concrete to assess.
2. Choose a plug adapter separately
Electrical Safety First's adapter advice states that a travel adapter does not convert voltage or frequency. It also highlights maximum power ratings and equipment that needs an earth connection. Check those requirements on the exact adapter you intend to pack.
“Universal” on the box does not answer every compatibility question. Read its destination list and equipment restrictions before buying. Choose a reputable retailer and inspect the adapter for damage. If it does not fit properly, do not force it into the socket.

3. Give hair appliances their own decision
A hair tool should have its own model-specific check, even when your phone charger accepts a wide voltage range. For example, Dyson's US Supersonic r Professional page identifies that product as 120V and recommends use in its country of purchase. That is a particular model and market, not a statement about every Dyson product or every hair dryer.
If the manufacturer does not approve your intended setup, leave the appliance out of the bag. Ask your accommodation what equipment it provides and whether it meets your needs. Confirm availability with the property rather than assuming every room has the same items.
4. Build a kit around your actual charging schedule
- List what must charge overnight and what can wait until another day.
- Match each cable to its device and approved power supply before putting it in the pouch.
- Keep one essential charging setup easy to reach on arrival.
- Check accommodation rules before packing extension equipment.
- Pack the instructions or a saved support answer for any unusual equipment.
This small inventory also helps before checking out: count the devices, cables and adapters against the same note. Keep the charging pouch beside your departure checklist so an adapter left in a wall socket is less easy to overlook.
5. Check the room before connecting
Use a suitable, undamaged socket and follow the equipment instructions. Electrical Safety First warns against damaged fittings, wet-hand use and ignoring burning smells or crackling. If something looks wrong, stop using it and tell the property staff.
