The crock pot is fused at 15 amps or rated at about 180 watts. The manufacturers assume that the operating voltage will be nearer 14 volts than 12 expecting most will be driving while using it and be running it off the tow vehicle's
generator. As Tom suggested this is a lot of power for the typical solar system though definitely possible.
We have an 80 watt panel on our
Scamp 16 and it is more than adequate for all our LEDs,
fridge fans, wi-fi hot spot, computer/phone charging, sat dish and LED TV.
We have a single type 24 battery. In the future we plan to get a larger single battery, though the 24 has been fine for all our travels, probably because we never run our
Propane furnace.
We also have the ability to charge our battery from our CRV while driving. This suggests that one could be cooking their meal on drive days heating the crock pot from the tow vehicle's
generator power. The crock pots do look nice in that the cover can be locked in place.
As to all other needs, our 80 watt fixed position
solar panel has been adequate to meet our needs.
