From Northern Ireland to Saint Martin
When travelling from Northern Ireland to Saint Martin: None of your Northern Ireland plug types fit in Saint Martin. You will need a travel adapter. Voltage matches at 230V, so a basic plug adapter is enough for most devices. Frequency differs (50Hz → 60Hz). Modern phone and laptop chargers are usually fine, but some clocks, motors, and appliances may behave incorrectly.
