Power sockets

Which types of electrical outlets are used on the Cook Islands?

The Cook Islands use electrical outlets of type I. Electrical outlets of type A and B, which are common in the United States, are not in use on the Cook Islands.

Mains voltage

What is the Electricity Voltage on the Cook Islands?

The voltage on the Cook Islands is 240 volts.

The voltage, therefore, is higher than the 120 volts in the United States. This difference means that you have to be cautious when using electrical devices purchased in the United States:

You should read the instruction manual of your device and check at which voltage it is safe to use.

If the voltage stated in the user's manual or on the device's power supply differs from the mains voltage on the Cook Islands, you should either not use your device there, or buy a voltage converter before departing.

Utility frequency

What is the utility frequency on the Cook Islands?

The utility frequency on the Cook Islands is 50 Hertz.

The frequency, therefore, is lower than the 60 Hertz in use in the United States. This difference may not be a problem for most of your devices, but you still have to be cautious:

Devices that either measure time, or are equipped with moving and rotating parts, are particularly dangerous! So, if you plan to use shavers, heaters, kitchen appliances or alarm clocks on the Cook Islands, read the instruction manuals to see if these devices are safe to use on the local utility frequency.

If the mains frequency specified in the manual or on the power supply is different from the rate used on the Cook Islands, you should not use the device!
