All the microwave''s I''ve found so far were 110v models sold along with an inverter
, and think that will not be out of norm for a lot of 12v applicances.
Some of the easier 12v stuff to find comes from searching for RV applicances. There are 12v things like hair dryers, electric frying pans, vacuum cleaners, blenders, coffee makers, etc. Couple of easy links are:
Where they have a good sample. Just keep in mind that many of these RV items are not marine-quality. YMMV for safety, reliability and feasibility. I''d be real, real careful with anything that can burn-up, like hair dryers and frying pans. You can''t epoxy
them to safety, etc. and I''ve always thought its amps that hurt more than volts in this area.
Hope it helps some...
