If you plan to travel out of the country you need to know about voltage converters. Why? Because not all countries use the same voltage, so your appliances may not work in another country unless you convert the voltage. A voltage converter changes the voltage of an electrical appliance so you can use it in other areas of the world.
Much of the western hemisphere and some locations in the Pacific operate on 110 volts. Most other countries use 220 volts, and some countries use both 110 volts and 220 volts. So-called step down voltage converters change the voltage from 220 to 110. Similarly, step up voltage converters change the voltage from 110 to 220.
Some appliances, including certain battery charges, operate in a voltage range than spans from 110 or below to 220 and above, for example 100 volts to 240 volts. Such appliances are considered dual voltage and will operate in either 110 or 220 environments without a converter or transformer. The voltage rating on the appliance will give you that information. These appliances may, however, need a plug adapter to fit into outlets in other countries. Certain new models of hairdryers are dual voltage and come with plug adapters and folding handles, making them ideal for foreign travel.
You can buy a small travel converter or a voltage converter transformer. A small converter will only work with lightweight appliances such as electric clocks or shavers. You may be able to plug in several appliances to a single transformer, but a small travel converter is designed for use with one appliance at a time. Heating appliances, televisions, power tools, and coffee makers are common examples of products that require voltage transformers.
While voltage converters do not change the wattage of appliances (they only change the voltage), you must know the wattage requirements of your equipment in order to buy the appropriate size of transformer. Step up and step down voltage converter transformers range from 100-watt capacity to deluxe automative voltage regulators with over 3000-watt capacity.
Laptop converters/adapters, also known as AC/DC power adapters, are designed specifically for battery chargers, laptops, and similar electronic devices. They ensure safe voltage conversion in foreign countries.
When you travel you may want a power strip/surge protector to prevent overloading and for other safety precautions, just as you might use one back home. Universal power strips with surge protection work in both 110-volt and 240-volt systems. Look for a power strip that accepts plugs from as many different regions as possible.
Travel is exciting and stressful. When you venture into environments that are different from your own it helps to have some familiar creature comforts. How disappointing it would be to come back to your accommodations after a long day of business or sightseeing in a foreign country and find that you cannot use your laptop or multisystem TV or DVD player. A little preparation will ensure that you have the right voltage converter and plug adapters so you can use your appliances. A reputable and knowledge seller of electronics can advise you.
