Attention Customers Outside the USA/Canada: All my electrical items operate on 110 volts. If you have anything other than 110 volts (ie 220 volt), you then need to plug the 110 volt unit into a power adapter/ voltage converter to 220 volts. I cannot be held responsible for damaged/ melted items if these instructions are not followed.
