My impression is the big advantage of absorption fridges is they will run off a tank of propane for a long time. But Downside they are very slow to cool down and running off AC/DC they aren't very efficient. But yeah cheapest thing to do is get a furnace transfer switch and a generator. That seems to be how rural people in the upper midwest avoid freezing to death when the power goes out in the winter.
