Why Should You Get a Dual-Voltage Flat Iron?

When traveling abroad, you will find that the electrical systems supply different voltages. When you put the wrong voltage into an appliance, it either does not work or it blows the electrical components inside the appliance. This is the case for a flat iron that has the wrong voltage for the electrical supply.

When traveling outside continental USA, it is important to consider investing in a flat iron that has dual voltage as this will prevent damage to your flat iron and make sure that it works. Most flat irons with dual voltage have a switch to choose the voltage. However some work automatically to monitor the voltage and adjust accordingly. Having this dual voltage feature means that it is safe to use both abroad and at home.

If you don't have a dual voltage flat iron, you will need to carry a converter which converts the voltage into the suitable output. However, these can be extremely bulky and take up more space in your suitcase, making them less convenient for traveling.

Regions Where Voltage Varies

Voltage varies depending on the region of the world that you are visiting. Understanding the electrical requirements of each country will let you know whether you need a dual voltage flat iron or not. Whereas American appliances usually run on voltages of 110-120 volts, other regions tend to be higher. This is why they can blow electrical appliances.

The USA, Central America (Mexico to Panama) and Japan work on voltages that sit between 110 and 120 volts. The northernmost countries of South America also operate with this same voltage.  From Brazil downward, South America generally operates on voltages of 220-240V.

Other regions around the world operate on 220-240V, varying in the specifics of that number in between. While the actual plugs and plugs sockets vary, the voltage can be compensated for with a dual adapter. So while England works on 230V and Brazil works on 220V, a dual-voltage appliance will cover this range and can be used safely with both.

How to Choose a Dual-voltage Flat Iron

When considering a dual-voltage flat iron, the likelihood is that you are considering it for travel purposes. With this in mind, there a few are other features that you may wish to take into account. Size and weight are important factors as the bigger the flat iron, the harder it is to pack. Likewise, a heavy flat iron will reduce the amount of available weight you have in your suitcase.

Try to find a flat iron that has a hinge lock as this will prevent it from bursting open while you travel. If the spring is trying to continuously burst open, this can damage the flat iron as well as the items packed around it. Travel cases can also stop your flat iron from becoming damaged as it is moved about from one place to another.

It is important to remember that it is not only the voltage that is different when traveling abroad; the plugs and plug sockets also vary. Carrying the right travel adapter for your flat iron and the country you are visiting is important. If you are traveling to only one country, finding the specific adapter for that country is better, as specific adapters tend to be smaller than their universal counterparts.

However, if backpacking, taking a universal adapter will mean you only have to take one instead of a whole bunch of different ones. Many larger hotels can provide adapters, although smaller establishments or hostels might not.
