Do you have an adapter for European sockets?
a-dat-ta-TO-re — five syllables, stress on the fourth.
Ask at reception if you forgot your travel adapter. Italian hotels almost always have a small supply.
'Adattatore per prese europee' = adapter for European sockets. Italy uses Type F and Type L plugs (220V/50Hz). UK (Type G, 3-pin) and US (Type A/B, 110V) travellers need adapters. US travellers also need a voltage converter for devices not rated 110–240V.

Italy's electrical system runs at 220V/50Hz. US devices designed for 110V will be damaged if connected directly without a voltage converter ('trasformatore di tensione'). Modern laptops, phone chargers, and cameras are usually rated 100–240V and need only a plug adapter, not a converter — check the device label.
