From Antigua and Barbuda to Tonga
When travelling from Antigua and Barbuda to Tonga: None of your Antigua and Barbuda plug types fit in Tonga. You will need a travel adapter. Voltage is different (110V / 220V → 240V). Check your charger label; if it doesn’t list 240V you’ll also need a voltage converter. Frequency differs (60Hz → 50Hz). Modern phone and laptop chargers are usually fine, but some clocks, motors, and appliances may behave incorrectly.
