The table below summarises the plug types, voltage and frequency of electrical current in both Argentina and Cook Islands.
|Plug Types||C, I||I|
|Frequency of electrical current||50Hz||50Hz|
In Argentina there's more than one plug type in use.
What type of plug does your appliance have?
You will need this adaptor:
Socket Type C
(Argentina) to Plug Type I
No adaptor needed
Cook Islands uses Socket Type I, which is the same as the plug type of your appliances from Argentina. You will not need an adaptor.
The voltages found in Argentina (220V) and Cook Islands (240V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Argentina and Cook Islands is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
