The table below summarises the plug types, voltage and frequency of electrical current in both Somalia and Estonia.
|Frequency of electrical current||50Hz||50Hz|
Somalia uses Plug Type C.
You will need this adaptor:
Socket Type C
(Somalia) to Plug Type F
The voltages found in Somalia (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 Somalia and Estonia is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
