The Balearic Islands are an archipeligo in the Mediterreanean sea, off the coast of Spain. They make up a province of Spain. However, the Balearic Islands operate differently from mainland Spain in a few ways. If you are planning on visiting mainland Spain and the Balearic Islands , you may have bought some supplies to help you use your own electronics there. Spain uses both 110v and 220v voltage. Some areas use only 110v, and others only use 220v. This is why it is a good idea to bring voltage converter s with you to Spain. The United States uses 110v, so your electronics need a voltage converter to work properly in 220v.
The Balearic Islands is one area in Spain that only uses 220v. Buy a voltage converter that is 25% higher in wattage than the appliance you intend to use it with. This will help the voltage converter to last longer.
If you are bringing rechargable electronics to Spain and the Belearic Islands, like digital cameras, or laptop computers, check and see if they are dual-voltage. Many rechargable items are dual-voltage, and do not need voltage converter s. Dual-voltage appliances list 110v-220v as their voltage rating, on their indications panel.
Another difference mainland Spain has with its province in the Balearic Islands is the electrical plugs. Mainland Spain uses two types of plugs. One of these types is the one you are used to, the American plug with two flat prongs and one round one. The other type is the European plug, the most common type of plug used around the world. It has three rounded prongs.
The Balearic Islands use only one type of plug, and it is not either of the plugs found on mainland Spain. It is a plug with only two rounded prongs. Be sure to buy all the compatible plug adapters you need, and be sure to buy the correct one, because there are six different plug adapters available, making it easy to get confused.
