What type of power adapter is used in italy?

In Italy, Apple sells power adapters with the 2-pin plug Type C [Europlug] (typically for devices up to 2.5 amp). This should be compatible with outlets Type F and Type L (10 amp style socket) as found in Italy.

The Apple World Travel Adapter Kit has several duck head models to slip on a power adapter.

Third party resellers may sell these (or similar and fitting) individually, in case you want just one model.

Apple only offers the World Travel Kit, which comes with a number of power adapter duckheads. I suggest that you verify what electrical outlets are available in Italy, and then, review this kit to see if it has the correct duckhead(s) needed.

To find out what outlets are in Italy, please take a look at the following: Plug, socket, & voltage by country

The Apple World Travel Kit includes the "Type C" head, which is one of the types used in Italy.
