Italian Plugs: yes, they are confusing
Type L: CEI 23-16/VII (Italian 10 A/250 Volts and 16 A/250 Volts)
The Italian earthed plug/socket standard, includes two models rated at 10 A and 16 A that differ in contact diameter and spacing. Both are symmetrical, allowing the live and neutral contacts to be inserted in either direction.
The double standard was initially adopted because in Italy, up to the second half of the twentieth century, the electric power used for lamps (Luce = lighting) and the one used for all other appliances (Forza = electromotive force; or Uso Promiscuo = general purpose) were sold at different fares, charged with different taxes, accounted with separated electricity meters, and sent on different wire lines that ended with different sockets. Even though the two electric lines (and respective fares) were definitively unified during the summer of 1974 many houses kept twin wires and twin electricity meters for years thereafter. The two gauges for plugs and sockets thus became a de facto standard which is still in use today. Older installations often have sockets that are limited to either the 10 A or the 16 A style plug, requiring the use of an adapter if the other gauge needs to be connected.
CEE 7/16 (type C) ungrounded Europlugs are also in common use; they are standardized in Italy as CEI 23-5 and fit most of the appliances with low current requirement and double insulation.
Appliances with Schuko-French plugs are often sold in Italy too; however not every socket will accept them since the pins of the Schuko-French plugs are thicker than the Italian ones. Adapters are cheap and commonly used to connect CEE 7/7 plugs to CEI 23-16/VII sockets,
Outside of Italy, Italian 10 A/250 V plug is found in Syria, Libya, Ethiopia, Chile, Uruguay, various countries in North Africa, and occasionally in older buildings in Spain.
How to Determine if you need just a Plug Adapter or a Voltage Converter
the back of a Sony power brick that requires 120 volts of AC electricity at 60 Hz or cycles per second. You will need a voltage converter to run the device that this attaches to. It's very low wattage though, only 6 watts, so you don't need a big, expensive converter.
a battery charger shows it will handle any voltage from 100 to 240 at 50/60 hz. This was designed to work just about anywhere in the world, and the US version will work in Europe by using a plug adapter as seen below.
Here is all you need to convert the US rectangular pronged plug to a European round plug used in most places in Italy.
