Power or Electricity in Cuba

In Cuba, many hotels and resorts have an electrical current of 110V60Hz. Some more modern accommodations also have a dual voltage system with some sockets running at 220V. The majority of outlets accept U.S.-style 2-3 prong plugs, though some also accept European rounded 2-3 prong plugs.  Power outages in Cuba became more common in 2023 due to fuel shortages. Some of the accommodations used have backup power plants (generators) to address this. But not all. Travel to Cuba with Cuba Unbound means accepting the fact that this is a poor country and that not all our accommodations will have backup power.  If power goes out and there is no backup power, air conditioning or fans are not available, cell phones won't charge, etc.
