Do You Need a Voltage Converter?

To avoid electrical problems, always verify the voltage rating on your device before traveling. If it says “100-240V, 50/60 Hz”, your device will work in most places without a converter. This is common for phones, tablets, laptops, cameras, and rechargeable gadgets.
