A quick google search and you will find a few options. Do you have a 12V output as well? BCF sell a Waeco 12V kettle that apparently draws 20A (only 240W). The thing to keep in mind is that the lower the power the more time the kettle will take to boil.
If I was you I’d buy a cheap stove that screws onto a Coleman type cylinder and use that with a normal kettle. Cheap, quick, easy, compact and no noise.
