Forgotten your adaptor and already abroad? Don’t worry — airports and local shops usually stock them. That said, packing your own saves you from high prices and poor quality.
Sint Maarten is often combined with nearby islands like Saint Barthélemy and Anguilla. It’s smart to check the plug info — different territories can use different systems.
Do You Need a Voltage Converter?
You’ll only ever need a voltage converter if your device’s voltage doesn’t match the country’s. In Sint Maarten you won’t need one — the mains voltage is roughly the same as in the UK.
Before you connect to the mains abroad, make sure the label says ‘100–240 V, 50/60 Hz’ — in that case, no voltage converter is needed.
