Best Choice Products Portable Mini Fridge Cooler And Warmer

This portable unit combines cooling and warming functions in a small footprint, typically holding around 4 liters of volume. 

Enough for about six standard 12-oz (355 mL) cans or similarly sized items like skincare bottles, snacks, baby bottles, and small food containers. It is powered via both AC (wall) and DC (car socket) inputs, making it ideal for both home and on-the-go use.

Cooling

The fridge relies on thermoelectric cooling technology, which is common in portable refrigerators of this size and price point. 

Rather than a compressor, it uses a semiconductor system that cools contents to a set number of degrees below ambient temperature - typically enough to chill beverages and personal items, but not to freeze them.
