With the appropriate adaptor for each U S-designed plug, can it be plugged into a European-style outlet?
I am going to France next month for a river cruise. The river boat will only have the 220 plugs available in our cabin. Most of my electronic needs already can handle the dual voltage requirement for use in both the US and in Europe. If I put the appropriate plug adaptor onto this outlet's US-style plugs, can I plug it into the hotel's and the boat's 220 outlets so that I can then use my US dual voltage items without their own adaptors?
