The Cook Islands’ Voltage and Frequency
In Rarotonga and the Cook Islands, the electric current is 240v 50Hz. This means that the electrical current is 240 volts with 50 cycles per second.
If your country of origin uses a voltage that ranges between 220v and 240v, then you will be able to use your appliances and gadgets in the Cook Islands with no problem at all. This includes countries like New Zealand, Australia, Europe, the UK and the majority of Asia and Africa.
If you are from North or South America or any country that uses a voltage between 100v and 127v then you will need to have a power converter or transformer. Many travel adapters include this function so there is no need to get yourself two separate items – check out the Amazon selection.
Will My Appliances Work in the Cook Islands?
If you’re using appliances from a country that also uses 220-240v, then they will work in the Cook Islands as long as they have a Type 1 output or you have a travel adapter. More on that later.
If coming from a country that uses 110v/120v, for example, then you should find that modern appliances, such as phones and laptops, are designed to use from 110v to 240v. Nevertheless, you should check the labels of all of the appliances that you intend to use in the Cook Islands.
Appliances that don’t clearly state that they can be used for up to 240v should not be used in Cook Islands electrical outlets. Otherwise, the higher voltage than required could damage your appliance (or worse). The most common types of appliances this applies to include hairdryers, electric razors and irons.
Do You Need a Convertor / Transformer for the Cook Islands?
If the label on your appliance states a single voltage number, such as 110v or 120v, (i.e. any number other than 240v), you will need a travel adapter which is also a voltage converter.
If the label has a combined low/high number, such as 120v/240v or 100v/240v, or a voltage of 200 or higher, you don’t need a converter.
Can You Use a 60Hz Appliance in the Cook Islands?
The Cook Islands uses a 50Hz outlet. Therefore, it is not recommended to use a 60Hz appliance, even if the voltage of your appliance is compatible with the Cook Islands. Using the wrong frequency (which is what Hz is) can cause appliances to stop functioning properly.
Again, check your appliance label. Some appliances work on both 50Hz and 60Hz.
Cook Islands Travel Adapters
Yes, regardless of the voltage, if your appliances are from a country that doesn’t use Type 1 power plugs then you will need a Cook Islands travel adapter. In other words, a Type 1 travel adapter.

It’s not the fastest way to charge your device but it will do the trick in case you lost your adapter.
