Plug adapter for Thailand from South Korea
What travellers from South Korea need to charge and power their devices in Thailand: plugs, voltage and frequency, with the rest of the trip basics below.
Plug adapter
Needed for some plugs
Your Type C plugs fit. For Type F plugs, bring an adapter to Types A and C.
Voltage
Same band
South Korea 220 V → Thailand 230 V. No converter needed.
Frequency
Different
60 Hz → 50 Hz. Chargers don't mind; mains-timed clocks and some motors may run fast or slow.
Your plug, their socket
Fit most round two-pin sockets, without earth
In Thailand: Most sockets are combined sockets that accept Type A and Type C plugs; newer buildings use the Thai Type O socket. Supply is 230 V, so US devices that are not dual-voltage need a converter even though the plug fits.
Your devices in Thailand
Look for the “INPUT” line on the charger or label. A range such as 100–240V ~ 50/60Hz means the device adapts by itself and needs only a plug adapter.
| Device | Usually | In Thailand |
|---|---|---|
| Phone, tablet and laptop chargers | 100–240 V | Plug adapter only |
| Camera and power-bank chargers, e-readers | 100–240 V | Plug adapter only |
| Electric shavers, toothbrushes | often 100–240 V; check | Works with the adapter |
| Hair dryers, straighteners, curling irons | single voltage | Works with the adapter |
| Kettles, irons, travel cookers | single voltage, high power | Works with the adapter |
| Plug-in clocks, timers, some fans | 60 Hz | May run fast or slow on 50 Hz |
