Varying different combinations of standards and voltages can often lead to confusion when planning on staying in a foreign country for the first time traveller. If you are staying in Cuba this page has useful instructions showing how to power your iPhone 4S using the standard Type C, A or B 110 volt 60Hz power outlets, most Cubans use the Type C power outlets. If the iPhone 4S charges slowly or does not power up when travelling to Cuba from a different region check that it is compatible with a 110 volt power supply. Electrical devices which originated from a country which use a higher voltage such as 240 volts sometimes take longer to charge or won't turn on, so check that the device is dual-voltage (you'll find these are usually marked with a 100-240 volt notation) otherwise you may need to use an additional power transformer to ensure proper use. If you plan on staying somewhere such as Havana or Santiago de Cuba please read the Cuba Wikipedia web page [1] for more information prior to the area. These instructions assume that you are running Apple iOS 7 or greater on the iPhone 4S.

What is the best power charger for recharging the iPhone 4S in Cuba?

When you are travelling with more than your iPhone 4S and visiting more than one country then the best travel adapter for Cuba to buy is a multiple USB port charger which includes swappable plugs like a 4 port USB travel charger [10]. There are three different standards of wall outlets that Cubans use (types C, A and B) and using a travel charger like this will ensure that you are covered for both types A and C.

Because these chargers are supplied with interchangeable plugs and can handle from 100 - 240 volts will mean you can travel to over 100 countries around the world simply by changing the supplied heads. If your type of iPhone 4S can support Fast Charge (not all USB devices will) then you'll benefit from much faster charging times with one of these types of USB travel chargers and additional compatibility with certain power demanding devices.

Having a 4 port adapter will allow you to recharge more than one device at once without needing to pack individual travel adapters for your Cuban trip. Only bringing a single travel charger will also keep the overall size down, making it perfect to fold up and store in hand luggage as well as being convenient for recharging your iPhone 4S at the airport or on a flight. Because of their space saving flexibility these types of chargers can be used at home so when you're not on holiday they can sit under your bedside table charging multiple tablets, smartphones and e-readers using just a single plug socket.

For those travelling frequently we suggest buying this type of versatile travel adapter at your preferred electronics retailer; the multipurpose travel charger illustrated is the 4 Port USB Wall Charger [10] which has been successfully tested with multiple USB devices in numerous countries on a daily basis.
