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