The table below summarises the plug types, voltage and frequency of electrical current in both Cook Islands and Tajikistan.
| Cook Islands | Tajikistan | |
|---|---|---|
| Plug Types | I | C, I |
| Voltage | 240V | 220V |
| Frequency of electrical current | 50Hz | 50Hz |
Cook Islands uses Plug Type I.
In Tajikistan there's more than one socket type in use.
You will need this adaptor:
Socket Type
(Cook Islands) to Plug Type C
(Tajikistan)
Tajikistan also uses Socket Type I, which is used in Cook Islands. If using an appliance that has a Type I Plug in the Type I Sockets of Tajikistan, you will not need an adaptor.
The voltages found in Cook Islands (240V) and Tajikistan (220V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Cook Islands and Tajikistan is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
