Yes!
The Europe Magic Wand has a switch mode power supply inside that can convert both 110 V @60 Hz & 230 V @50 Hz, so you might only need a plug converter. Both 110 V and230 V will give the same power output in terms of vibrations.
If you have an earlier model, you need to check the serial number on your Europe Magic Wand. If it is 15xxxxx or above, it will work in the US with only an adaptor for the wall. If the series number is 14xxxxx or below, you will probably need a voltage converter also, as the minimum voltage is around 120 V on these versions.
