Voltage converters and voltage transformers change electric current from 220/240 Volt (Foreign Electricity) to 110/120 Volt (U.S. Electricity) which is called step down. There are step up voltage converters that change 110/120 Volt (U.S. Electricity) to 220/240 Volt (Foreign Electricity) and Voltage regulator converters that can Step up and Step Down which are 10-220 volts 50/60 HZ for use anywhere!
North America operates on 110 volt
electric current, whereas most countries in the world run on 220 volts
and even as high as 240 volts. So if you wish to use your U.S. or
Canadian 110 volt items overseas, your appliances will require a
voltage transformer or voltage converter.
Voltage converters and voltage transformers are the same concept:
they will turn the power of 110 volts into 220 volts, or 220 volts into
110 volts. Even if this will allow you to use your electrical equipment
in almost every country in the world, plug adapters may be needed too,
considering that plug outlets vary from country to country.
Most items, such as hair dryers, electric shavers, irons, coffee
makers, TVs, VCRs, or DVD players, require power to operate;
unfortunately, the power voltage available is not always what's needed.
In this case, you will need either a 110 / 120 Volts to 220 / 230 / 240
Volts voltage converter, or voltage transformer; or otherwise a 220 /
230 / 240 Volts to 110 / 120 Volts voltage converter, or voltage
Converters and transformers change electric current: Converters
are designed to work only with electric appliances (for example: hot
pots and hair dryers); Transformers are designed to work with
electronic items that have a chip or a circuit (for example: camcorder
recharges and radios AND electric appliances).
Voltage converters and voltage transformers are available in
different wattage combinations: converters are available from 50 to
1600 watts. Transformers are available from 1 to 100 watts, 200 watts,
300 watts and stronger. Your transformer will either step up and down
the power (change 110 / 240 volt electricity into 240 / 110 volts) or
step it down (change 220 volts to 110 volts) so you can safely run your
You should know that you will never damage your appliance if you
use a higher wattage transformer, and if you buy one that is not
powerful enough, it will not work.
Some popular brand names for voltage converters (Voltage Transformer) and adapters include Regvolt, Seven Star, Simran, Franzus, Tripplite, and Travelsmart.
