The table below summarises the plug types, voltage and frequency of electrical current in both Angola and Cook Islands.
| Angola | Cook Islands | |
|---|---|---|
| Plug Types | C | I |
| Voltage | 220V | 240V |
| Frequency of electrical current | 50Hz | 50Hz |
Angola uses Plug Type C.
You will need this adaptor:
Socket Type C
(Angola) to Plug Type I
(Cook Islands)
The voltages found in Angola (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 Angola and Cook Islands is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
