Small handy refrigerator. We put in our caravan to replace one that was out of use. It requires a bit of studying the size and adapt (cans instead of bottles, no large food wrappers), but very small and convenient as with a cigarette lighter. The caveats: - Noisy (but we used to background noise) - Takes a long time to cool (incidentally, the instructions suggest locating breads ice in at the beginning, like a glacier). By cons, once cold, it does not weaken and has the same features as a traditional refrigerator.
