No she is a US ship so she has either USA 2-pin or European plugs. Yes, there is a kettle.
RCI have dual voltage and there is a shaver point in the bathroom and both usa euro plugs take an adapter they provide a hair dryer but RCI & Celebrity do not provide a kettle in the cabin,but you have room service and plenty of places to get fresh tea&coffee day and night .
To correct Mr Buckley - YES there is a kettle in all Independence cabins - to appease the British market who like their morning cuppa.
Independence is the first RCI ship to have kettles..
