A:Answer The purpose of the third prong is to provide a path (to ground/earth) if the appliance had an overvoltage problem. If you bypass this path by using a converter plug, that voltage will find the easiest path it can. This will be any metal it can find, or you if you touch said metal. Since the case isn't metal, you won't easily touch metal. However, the manufacturer used a three prong plug implying you can get a shock if an overvoltage event occurs and you touch the wrong thing. Short answer, nothing stops you from using an adapter, but I wouldn't recommend it unless you know what you are doing.
