Irish sockets are the same as UK ones, the 13Amp (Type-G). 50Hz, at 230V

As an Italian citizen, what legal documents we are supposed to carry when we will be traveling to Ireland?
Passport or national ID card (carta d’identità), provided it does not say non valida per l’espatrio on the back. If the carta does say this then it is not valid as a travel document outside of Italy.
Also what electrical adapter (for mobile and laptop) I should carry with me?
Ireland uses British BS1363 sockets, so you’ll need an adapter.
You need either a carta d’identità or passport to enter Ireland – a driving licence is not a travel document and as such will not do.
Granted, in actuality anyone who can prove beyond reasonable doubt that they are an EEA national (a driving licence alone is not sufficient for this) should be let in by immigration authorities, but good luck getting on a plane with that argument – airlines may face a hefty penalty for transporting a passenger inadmissible to the destination country.
