Aruba is a small island in the Lesser Antilles island chain in the southern Caribbean Sea. Whether you are going there to experience the warm climate, the scenery, or to visit family, you should know that Aruba also uses American plugs. You may have prepared to bring plug adapters, but this is not necessary. All of the electrical outlets in Aruba are designed for American-style plugs. Of course if you are from Europe you will want to bring a plug adapter so your appliances can fit into the American-style outlets. But be sure to buy the correct one, because there are six different types of electrical plugs used around the world, and likewise as many types of plug adapters.
Many 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. However, in Aruba , the voltage used is 110v, just like the United States. So if you are going to Aruba , all you need is a plug adapter, and you do not need a voltage converter .
