TRAVEL TO AUSTRIA WITH THE CORRECT PLUG ADAPTERS

Most countries in Europe, Asia, Africa, and Australia use 220v.
If you found a voltage rating on your appliance that listed 110v-220v, then it is dual-volt. You do not need a voltage converter for these appliances to function in Austria and other countries that use 220v electrical current.
However, even if you are bringing dual-voltage electronics with you to Austria , you still need a plug adapter, because Austria uses a different type of plug than the United States. But be careful when buying your plug adapter, because there are six different types of plug adapter corresponding to the six different international plug types, and if if you get the wrong one, it won’t work in Austria . So be sure to buy the correct one.
