The first thing that I absolutely suggest to buy is a very useful and cheap kit power point adapters.
Their aim is to adapt the electrical plug of your fixture (phon, videocameras, chargers...) to every kind of power point you will find around the world.
Notice that they only adapt the plug shape but they do not modify their voltage

If voltage is 220V-230V-240V or 250V Italian electrical apparatus works well (so you only need to bring the adapter with you).

If your apparatus works only with Italian voltage :
you need to buy particular kits that have not only adapters but also electrical voltage transformers and you can range voltage from 110-127V to 220V-250V.
