When traveling abroad, you always need to be aware of where you're going, because there's a chance your electronics may not plug in! Fortunately, when visiting Cuba, most hotels and resorts will have our American 110v socket in the rooms. However, we highly recommend you bring a 110>220 converter as some rooms could be 220v only.
Curious about electronics and what you can and cannot bring? Fear not: there are no Cuba travel restrictions for bringing electronics, and you may take along any you wish that will make your trip more enjoyable. Hotels will have hair dryers but sometimes no alarm clocks (although a wake up call can be requested if you don't want to use your cell phone!) There is no problem bringing laptops, cell phones, tablets, or other electronic devices through customs, so take your favorite gadgets!
