A:Answer We just returned from a trip to Vienna and Paris and used the adapter when in Vienna. I used it for my curling iron, and was surprised to see that got so hot that it melted the plastic tip off the top of the curling iron! After checking the adapter, in very fine print (not on the box when we purchased it) was a warning that this is an adapter NOT a converter. Fortunately, we had a second adapter converter(different brand) with us that worked just fine. Also fortunately, we had not tried this out on our cell phones. I can't imagine a company that would make an adapter that allows you to plug into an electric circuit not compatible with your device without a means to convert it.
