Electrical service in Holland and on board Aurora is 220 volts/50 hertz. If using appliances from either the US or Canada you will need both a socket plug adaptor and a voltage converter. This equipment may not be readily available overseas, so if you plan to travel with an electric appliance, remember to pack your converter/adapter too. All laptops / iPhones, iPads, iPods work happily & there are many charging points onboard. We have travel adapters if you need them.
