The table below summarises the plug types, voltage and frequency of electrical current in both Cook Islands and Turkey.
| Cook Islands | Turkey | |
|---|---|---|
| Plug Types | I | C, F |
| Voltage | 240V | 230V |
| Frequency of electrical current | 50Hz | 50Hz |
Cook Islands uses Plug Type I.
In Turkey there's more than one socket type in use. You may require more than one adaptor.

The voltages found in Cook Islands (240V) and Turkey (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Cook Islands and Turkey is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
