Based on the search results, I would recommend either the Alpicool 25L Portable Refrigerator Car Fridge for R4099 or the Zero Appliances RV35 12 220V Portable Chest Fridge Freezer for R6850. Both of these options are small portable fridges that would work well for a smaller space. The Alpicool is a decent size at 25L but very affordable, while the Zero Appliances fridge freezer provides extra storage and temperature control with both fridge and freezer sections. Let me know if you need any other details on these options or have a different size in mind. I'm afraid I don't have access to listings outside of this search, but I hope these suggestions are helpful nonetheless!
