The electrical current in Italy is 220 volts, 50 cycles alternating current (AC); wall outlets accept continental-type plugs, with two or three round prongs.

You may purchase a universal adapter, which has several types of plugs in one lightweight, compact unit, at travel specialty stores, electronics stores, and online. You can also pick up plug adapters in Italy in any electric supply store for about €2 each. You’ll likely not need a voltage converter, though. Most portable devices are dual voltage (i.e., they operate equally well on 110 and 220 volts)—just check label specifications and manufacturer instructions to be sure. Don’t use 110-volt outlets marked “for shavers only” for high-wattage appliances such as hair dryers.
