The table below summarises the plug types, voltage and frequency of electrical current in both Iran and Azerbaijan.
| Iran | Azerbaijan | |
|---|---|---|
| Plug Types | C | C |
| Voltage | 230V | 220V |
| Frequency of electrical current | 50Hz | 50Hz |
Iran uses Plug Type C.
No adaptor needed
Azerbaijan uses Socket Type C, which is the same as the plug type of your appliances from Iran. You will not need an adaptor.
The voltages found in Iran (230V) and Azerbaijan (220V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Iran and Azerbaijan is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
