The small 12v coolers like you describe are often used for transporting queen cells from an incubator to the mating yard. I can easily see how it would work for a small quantity of jars. My incubator is large enough to hold a 5 gallon bucket so that is what I would use if my honey ever crystalized. I still have a jar from 2017 that is as liquid as the day it was made. I guess creamed honey is not in my future.
