The present USA voltage standard range is 120/240VAC 60Hz at +-5%, and has been for many years. There are exceptions to this in large buildings, where polyphase systems are sometimes used, but standard single phase residential and light commercial is all 120/240 service. We haven't had 110/220 for well over 60 years.
Europe's electrical system is different from ours in two ways: the voltage of the current and the shape of the plug. American appliances run on 110 volts, while European appliances are 220 volts. Today's gadgets are dual voltage, which means they work on both American and European current. If you see a range of voltages printed on the item or its plug (such as 110â220), you're OK in Europe.
