Do You Need a Voltage Converter?
You’ll probably need a voltage converter in Saint Helier since your device’s voltage has to match the local power supply. In the U.S., we use 120V, but Saint Helier operates on a different voltage, so a converter is required.
Before using your electronics in another country, always check the voltage label to make sure it’s compatible. If it states “100-240V, 50/60 Hz”, your device can handle both 120V and 220-240V without needing a converter. Many modern gadgets, including laptops, tablets, and cameras, support this.
