Has anyone ever wondered about connecting powerful (1KW and above) European electronics 220 volts to an American 110 volts network? What solutions are there? For example, an iron or a coffee machine, or say, a washing machine?
There ought to be a transformer, but those Chinese ones that are sold everywhere are not trustworthy.
For instance, the most powerful consumer-grade step-down transformer I found was 300W for 1700 rubles http://www.zapitatel.ru/catalog/ponizhayushchie-avtotransformatory-220-110-volt/thg-300s-/
But I doubt it could handle an iron.
