Cook Islands Technical Information – In Details

Cook Islands Voltage

The voltage in Cook Islands is 240 V which is the same voltage used in Australia, Kuwait, and Malaysia.

Note that the 240 V is the highest voltage used in the world and therefore the most dangerous.

240 V has an advantage over lower voltage such as the 110 V that it is cheaper to transmit. On the other hand, 240 V is more dangerous than lower voltages.

Cook Islands Electrical Frequency

The electrical frequency in Cook Islands is 50 Hz.

Note that most household and electrical/electronic equipments nowadays support multiple frequencies, so generally, electrical frequency is not an issue compatibility wise.

Cook Islands Plug/Socket Type(s)

Cook Islands uses the I plug.

Plugs/sockets are usually an issue when it comes to traveling, so always make sure you travel with a universal plug adapter.

Cook Islands DVD Region

Cook Islands uses DVD Region 4.

DVD Region 4 is mainly used in Australia, South America (Mexico, Argentina), and Central America (Guatemala, Cosa Rica…).

Note that a region 4 DVD cannot play on a DVD player supporting another region. There are, however, some region free DVD players available that can be used to overcome this.

Cook Islands Blu-ray Region

Cook Islands uses Blu-ray Region A.

Blu-ray Region A is used in North/Central/South America, Japan, Taiwan, North Korea, South Korea, Hong Kong and Southeast Asia.

Theoretically, a region A Blu-ray disc should not play in Blu-ray disc players supporting another region. However, most Blu-ray discs are now region free (meaning they can work on any Blu-ray disc player), and most Blu-ray players are also region free. Hence, compatibility is rarely an issue (for now) when it comes to Blu-ray discs.

Cook Islands GSM Freqency(ies)

Cook Islands uses the GSM 900 GSM frequency.

When travelling, make sure that your phone supports the GSM frequency of the country you’re traveling to. Usually the supported GSM frequencies are printed on the box of your phone as well as its manual.
