Smurf and Rojie
many thanks, Ive managed to find a dual voltage electric kettle and the adapator works...and yes if I could get a Japanese/US two pin plug and connect it to an appropriate UK socket, with a short length of flex, I will, as it will be a better fit. The vehicle is from Campervanco and I could buy a stovetop kettle/or use a pan which I have but its a question of space when loaded up on the move.
Thanks again
