The table below summarises the plug types, voltage and frequency of electrical current in both Korea, North and Laos.
| Korea, North | Laos | |
|---|---|---|
| Plug Types | C | A, B, C, E, F |
| Voltage | 220V | 230V |
| Frequency of electrical current | 50Hz | 50Hz |
Korea, North uses Plug Type C.
In Laos there's more than one socket type in use. You may require more than one adaptor.
Socket Type C
(Korea, North) to Plug Type A
(Laos)
Socket Type C
(Korea, North) to Plug Type B
(Laos)
Socket Type C
(Korea, North) to Plug Type E
(Laos)
Socket Type C
(Korea, North) to Plug Type F
(Laos)
Laos also uses Socket Type C, which is used in Korea, North. If using an appliance that has a Type C Plug in the Type C Sockets of Laos, you will not need an adaptor.
The voltages found in Korea, North (220V) and Laos (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 Laos is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
