It depends on where your plugs come from.
🇺🇸 From the United States
Your plugs fit some compatible outlets in Sint Maarten, but not every listed socket design. An adapter may be needed for the outlet you encounter. Check the actual outlet and preserve any grounding your device requires; hybrid connections may not be grounded.
No voltage converter needed. Both countries use 120 V.
United States to Sint Maarten in full🇬🇧 From the United Kingdom
You need a plug adapter. Plugs from the United Kingdom (Type G) don't fit the Type A and B sockets in Sint Maarten. A Type A (US 2-pin) adapter fits the listed socket families there. For grounded devices, get a Type B (US 3-pin) adapter for a compatible grounded outlet instead; it does not fit every listed outlet. Socket variants can differ; check the actual outlet and adapter rating.
Sint Maarten uses 120 V, lower than the 230 V in the United Kingdom. An input rating of "100–240V" covers the listed supply voltage; you still need a suitable plug or adapter. Single-voltage devices may run weakly or not at all.

Sockets you'll find in Sint Maarten
Will your devices work in Sint Maarten?
Sockets in Sint Maarten supply 120 V. Find the "input" line on each device or its charger. An input rating of "100–240V" covers the listed supply voltage; you still need a suitable plug or adapter. Check that the input frequency also covers 60 Hz. An adapter changes the plug shape, not the voltage or frequency. For switchable devices, follow the manufacturer's instructions before plugging in.
Often rated 100–240 V; confirm on the charger: phone charger, laptop charger, camera battery charger.
Check the label first: electric toothbrush, electric shaver, CPAP machine, hair straightener / curler.
Usually single voltage: hair dryer, kettle / coffee maker, anything with a heating element.
