Electric Current: Cuba uses the same electric standards as in the United States: 110V, though it is common to find both 110 and 220 in the more modern accommodations in Cuba (they are usually labeled). It is advisable to bring a converter, if your electronics are not travel-ready (105-240V). Outlet: Type A (North American/Japanese 2-pin) & Type B (American 3-pin) outlets are used on the island.
