The table below summarises the plug types, voltage and frequency of electrical current in both Uzbekistan and Tonga.
|Plug Types||C, I||I|
|Frequency of electrical current||50Hz||50Hz|
In Uzbekistan 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
(Uzbekistan) to Plug Type I
No adaptor needed
Tonga uses Socket Type I, which is the same as the plug type of your appliances from Uzbekistan. You will not need an adaptor.
The voltages found in Uzbekistan (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 Uzbekistan and Tonga is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
