If you are to
travel in another country with electrical appliances, the type of electrical voltage, plugs and outlets used in the destination country is the first issue you should consider before setting out. Most countries in the world use electricity at about 220 volts/50Hz, while countries in North America have an electricity supply of 120 volts/60hz. What's more, the wall outlet configurations also vary from country to country as more than a dozen different types of plugs are in use in the world.
