From Northern Ireland to Puerto Rico
When travelling from Northern Ireland to Puerto Rico: None of your Northern Ireland plug types fit in Puerto Rico. You will need a travel adapter. Voltage is different (230V → 120V). Check your charger label; if it doesn’t list 120V you’ll also need a voltage converter. Frequency differs (50Hz → 60Hz). Modern phone and laptop chargers are usually fine, but some clocks, motors, and appliances may behave incorrectly.
