The Canary Islands are an archipelago off the coast of Spain. You may be planning a trip there. You may want to experience the warm climate, the culture, or to study the unique and diverse island wildlife. However, you should know that the Canary Islands use electrical plugs that are shaped differently from the ones you are used to in the United States. You might be planning to bring some of your electronics to the Canary Islands , but American-style plugs are only used in some areas on the Canary Islands . There are six different types of commonly used plugs that are used around the world, and most countries outside North and South America use the common three-cylindrical-pronged design. The Canary Islands does not use this model, but it does use three others that are not as common. One of the types of outlet that is used is not one of the six common designes used, it is a rare type of plug that is not found in very many countries. But you do not need to buy new electronics in the Canary Islands in order to use any electronics there. You simply need plug adapters. Purchase both types that you will need in the Canary Islands , and be sure to buy the correct kind, keeping in mind the types of rare plugs that the Canary Islands use.
Most places outside of North America also use a higher voltage current. 110v is the voltage used by North America and most of Central and South America. However, in most other continents, 220v is used. In countries where 220v is used, it is important to bring a voltage converter that has a 25% higher wattage rating than the appliance you are using it for. In the Canary Islands , the voltage used is 220v, the most commonly used voltage. So if you are going to the Canary Islands , be sure to also get a voltage converter . This does not apply if you are bringing dual-voltage appliances. However, single-volt appliances will need a voltage converter . The wattage should be indicated on the indication panel of the devices. If not, multiply the voltage by the amp. Then you can buy the correct voltage converters for your selected appliances.
