The table below summarises the plug types, voltage and frequency of electrical current in both Tuvalu and Cook Islands.
| Tuvalu | Cook Islands | |
|---|---|---|
| Plug Types | I | I |
| Voltage | 220V | 240V |
| Frequency of electrical current | 50Hz | 50Hz |
Tuvalu uses Plug Type I.
No adaptor needed
Cook Islands uses Socket Type I, which is the same as the plug type of your appliances from Tuvalu. You will not need an adaptor.
The voltages found in Tuvalu (220V) and Cook Islands (240V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Tuvalu and Cook Islands is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
