The table below summarises the plug types, voltage and frequency of electrical current in both Belarus and Mongolia.
|Plug Types||C||C, E|
|Frequency of electrical current||50Hz||50Hz|
Belarus uses Plug Type C.
In Mongolia there's more than one socket type in use.
You will need this adaptor:
Socket Type C
(Belarus) to Plug Type E
Mongolia also uses Socket Type C, which is used in Belarus. If using an appliance that has a Type C Plug in the Type C Sockets of Mongolia, you will not need an adaptor.
The voltages found in Belarus (220V) and Mongolia (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Belarus and Mongolia is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
