The table below summarises the plug types, voltage and frequency of electrical current in both Korea, North and Estonia.
| Korea, North | Estonia | |
|---|---|---|
| Plug Types | C | F |
| Voltage | 220V | 230V |
| Frequency of electrical current | 50Hz | 50Hz |
Korea, North uses Plug Type C.
You will need this adaptor:
Socket Type
(Korea, North) to Plug Type F
(Estonia)
The voltages found in Korea, North (220V) and Estonia (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Korea, North and Estonia is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
