Thats a 12 volt Microwave, I thought he meant a regular one to run off a Gennie or when in port the shore line. 12 volt Microwaves are expensive, for what a regular one costs I wouldn't be without one.
can be very useful if you are out for a few days ,for quick hot,
premade meals. not exactly cordon b , but if it makes you go green
trying to cook in a bumpy sea ,micro wave can come up trumps.
see no point in having a 230 volt job as its easy to use 'proper'
cooking equipment in harbour or marina.
