How do I know if my device is dual voltage?
Dual-voltage devices are perfect for travel. When you’re bringing a hairdryer with you, it is safe to choose a dual-voltage hairdryer. A dual voltage hair dryer means that it can function both in the U.S. and abroad. You can know in your device how much volts needed to operate it by the print in the box. Plenty of hair dryers in the U.S. can only support lower voltages at 110V. When traveling internationally, especially in Italy, the device needs to support 240V. A dual voltage hairdryer typically looks like a regular hairdryer with a tweak on the surface. You can see a small switch on it where you choose the proper voltages. The voltages can either be 125V or 250V. Most hotels in Italy generally support the 250V. An easy way to know your hairdryer’s voltages, look for stickers and numbers printed on the plug. You can also see this in the base or handle of the device. It is on the box printed. To understand hairdryers, here is a comparison of single and dual voltages: Single voltage A single voltage hairdryer has a specific voltage number in it. For U.S. hairdryers, they usually have the 110V. If the device matched the power supply in Italy, 230V, then your hairdryer is usable in the country. In this way, you can easily use an Italian power outlet for your hairdryer. The single voltage hairdryer also has dash in the voltages. It can come as 100-120V to accommodate a gradual power surge. Your hairdryer should fall within the range of 230V when in Italy. Dual Voltage The power range in dual-voltage hairdryers is usually with a slash. You will typically see the 100/240V in the box of your device. It means we can use the hairdryer in Italy as it is capable of supporting 230V. You can use a dual-voltage hair dryer in Italy but other parts of Europe. It is versatile and a good investment, especially when you always travel abroad. It has two voltage options great for packing overseas.
