I bought mine in Best buy in Florida. before I moved to Europe, before that I traveled with it to EU. Straight out of the box in the USA without a issue will work on 220V. I have 2 of them. I can only speak for the Ultra
That's great then. The wall cube must be 110-220v compatible. Of course, the US version will have the wrong plug, so an adapter is needed. But no converter necessary.
