For Solid State / Electronic Violet Wands:
We recommend a 200-watt step down transformer. You may use a travel converter of 100 watts minimum.
But you must make sure you do not hit the converter with the output of the violet wand, as that can disrupt the converter, which will damage your wand, so use of your own travel converter is at your own risk.
For TESLA Violet Wands
Disruptive discharge wands, you cannot use the small ‘travel’ converters such as you use for your electric razors etc.
They are not built to handle the requirements and will burn out immediately, damaging your wand.
