Electricity and sockets
TerritoryYes – from the UK you need a travel adapter for the Cook Islands, because the sockets there (Type I) will not take your plugs.
Sockets at the destination
Sockets in the Cook Islands: Type I, supplied with 240 V at 50 Hz. At 240 V the supply matches what UK and European appliances expect, so no converter is needed.
The same socket system is used in Niue, Vanuatu, Fiji and the Solomon Islands, so one adapter covers all of them. Travelling further to Palau, Micronesia and Guam means a different adapter. In Oceania, 13 of 18 recorded destinations use exactly this combination.
Protective earth
Sockets in the Cook Islands are normally earthed.
