The table below summarises the plug types, voltage and frequency of electrical current in both Argentina and Tonga.
|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
Tonga 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 Tonga (240V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Argentina and Tonga is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
