Do You Need a Voltage Converter?
Since the voltage in Basseterre doesn’t match the U.S. standard of 120V, you’ll likely need a voltage converter to avoid damaging your devices.
Before plugging in your electronics abroad, always double-check the voltage label. If it says “100-240V, 50/60 Hz”, your device will work on both 120V and 220-240V power sources without a converter. This is common for tablets, laptops, cameras, and rechargeable toothbrushes.
