Power converters are readily available both online and wherever luggage accessories are sold. So what are they and are they really needed? A converter is a device that allows travelers to use their electronics when traveling to other countries. Many countries have different power outputs. To add to the confusion, different devices have different requirements. As a result, travelers need to carefully consider their travel destinations and the requirements of the devices they wish to take.
Defining a Power Converter
A power converter is a device that is used to convert voltage – either up or down. Like a normal power supply, the device supplies power in the form of alternating burst of sine waves. However, the device contains a circuit inside the unit that cuts the sine wave in half. In light of this, it can then match the output of amps to the power requirements of the device. Occasionally, converters are referred to by other names such as a switch mode power supply.
Types of Converters
There are various types of power converters that should be used for different purposes. A step down power converter is generally used on American or Canadian devices when traveling overseas. It protects devices that use 110 volts from the 220 amp supplied in European countries. A step up-down converter can be used for traveling to or from the US or Canada. Many frequent travelers prefer a smaller travel converter, but it should only be used on non-electronic heating devices such as hair dryers or coffee makers.
Why it’s Needed
Unfortunately, countries all over the world have different regulations when it comes to power supplies. In the US and Canada, most circuits run on 120 volt. However, much of the rest of the world including Europe, Australia, New Zealand and South America run on 220/240 volt. Since many appliances are not dual voltage, they are vulnerable to power surges. They will need additional amps to operate. Plug adaptors may be necessary because the size, shape and holes of outlets and plugs can be different as well.
Why the Difference?
So why the difference between countries when it comes to voltage? It really comes down to a difference in opinion as to what is considered safe and what is not. In the United States and Canada, regulations have been passed to keep circuits to 120 volts. However, in many other countries 220 volts is considered safe and is viewed as more practical, because it doubles the amount of outlets and lights that can be run on a circuit.
When You Need One
Of course, not every traveler needs a power converter. In general, it’s a good idea to own one if traveling anywhere outside the United States or Canada. Also, consider the types of appliances that you usually take. For electronic equipment such as laptops a power converter is a must, while appliances such as hair dryers need only a simple travel converter. Also, devices with dual voltage do not need converters, but equipment purchased from foreign countries might.
If you are considering a trip to a foreign country, a power converter may just be the thing to take. Most countries have different power supplies, and this can play havoc with sensitive equipment like camera equipment. However, a power converter can protect that equipment by altering the output of power to match the requirements of the device. Keep in mind that equipment with dual voltage may not require a converter at all, and some appliances may only need a small travel converter.
