Both sorts available: North American standard, 110 volts AC. European standard (220 volts AC, round prongs). Stateroom outlets can accommodate appliances up to 1500 watts.
Thank you for your quick response. Do you know if the hair dryers in the staterooms have a low heat setting as the high setting I find blows the air out too forceful. I am mainly concerned with my curling iron. It is a Conair Hot Air Brush and it clearly states in the instructions "do not use with a voltage converter". Do you have any suggestions for me ?? I will be bringing a 1500 watt converter with me in case I need it. Picky or what ?? Thanks again.
