Main Voltage in Cook Islands

Do I Need a Voltage Converter in Cook Islands?

Cook Islands runs on a main voltage of 240 volts at a frequency of 50 Hz. This is effectively the same as India's 230V/50Hz. You can plug any Indian device into a Cook Islands socket without a voltage converter, as long as the plug shape fits.

Will my Indian charger work in Cook Islands?

Your charger will work, but only with a plug adapter. Cook Islands uses Type I sockets at 240V/50Hz. Your Indian phone and laptop chargers are dual-voltage (the label reads 100–240V), so they handle Cook Islands voltage without any issue. The only question is plug shape — your Indian plug will not fit Type I sockets at all, so you must carry a travel adapter. You do not need a voltage converter — Cook Islands's 240V is the same as India's 230V.
