This compact countertop refrigerator can be squeezed into the tiniest of spaces. It has a capacity of 4 liters and a soda shop vibe. With just the flip of a switch this tiny model changes from cooling to warming. It can sit anywhere around a house or a dorm room and is portable enough to take on tailgates. This refrigerator plugs into an outlet but when you’re on the go it has a USB port and can be operated by a powerbank.
