Do they exist?

I am sure there are some out there, but..

Most "12V" items like this are nothing more than toys and will only draw 4oz-8oz (1 cup-1 pint)of water per 24hrs.

Peltier or solid state cooling devices do exist, apply 12V and one side gets cold and the other side gets hot.

The caveat with Peltier devices is they are absolute power hogs and they are quite limited in size and how much cooling (the fins must cool below the ambient air temp without freezing to condense moisture out of the air) you get and are highly dependent on the ambient air temp on how effective they are.

Buy the smallest 120V compressor based dehumdifier you can find and use a inverter, they work better than any battery powered dehumidifiers you will find.

absolutely. And yes, peltier heaters or coolers are very very very inefficient. That's what's used in the inexpensive 12V coolers you can buy. That's also what is used in our truck for the cooled seats. In that case, they actually do work reasonably well, but the back seat passengers definitely hear the noise from the unit and the fan.

Even the smallest 120V dehumidifier will pull 5 gallons or more of water out of the air in less than 24Hours if the humidity is even moderately high and keep windows from fogging, etc.
