Converter Question

I have a curling iron that says it is 20w - 40w, which I want to take to Spain with me next week. I bought a Samsonite International Converter Adapter set which says on the converter, "should only be used with heat producing appliances whose rating is 50 watts to 1600 watts." My question is, will the converter work with my curling iron which is LESS THAN 50 watts? Please help!

If you need small electrical appliances, buy them in Spain. Then, you will know that they will work. You won´t have to worry about the prongs, prong extenders, or the converters.

Also, I was told that you must be careful with converters because they are only meant to be used for a short time. They get very hot and will burn themselves up if left on very long.

Can you return your items and purchase them in Spain?
