From Svalbard and Jan Mayen to Tonga
When travelling from Svalbard and Jan Mayen to Tonga: None of your Svalbard and Jan Mayen plug types fit in Tonga. You will need a travel adapter. Voltage is different (230V → 240V). Check your charger label; if it doesn’t list 240V you’ll also need a voltage converter. Frequency is the same at 50Hz.
