The table below summarises the plug types, voltage and frequency of electrical current in both Tuvalu and Iran.
| Tuvalu | Iran | |
|---|---|---|
| Plug Types | I | C |
| Voltage | 220V | 230V |
| Frequency of electrical current | 50Hz | 50Hz |
Tuvalu uses Plug Type I.
You will need this adaptor:
Socket Type
(Tuvalu) to Plug Type C
(Iran)
The voltages found in Tuvalu (220V) and Iran (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Tuvalu and Iran is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
