It is indeed 220V only. When plugged into 110V nothing happens. I have been Using a step-up transformer. Since those power supplies that have the little switch in them aren't 2 completely different power supplies I figured a power supply could be re-done for 110V Seems like a waste to have a step-up add all that voltage just to have the power supply take it all back out.
