Do You Need a Voltage Converter?
A voltage converter is likely needed in St. John’s because your device must match the country’s voltage. The U.S. runs on 120V, but St. John’s uses a different voltage, so a converter is necessary.
Always double-check the voltage label on your electronics before traveling. If you see “100-240V, 50/60 Hz”, your device is compatible with multiple voltage systems and won’t need a converter. This includes phones, laptops, tablets, cameras, and personal care devices.
