Review on JoyTutus Portable Car Refrigerator 42 Quart: Compact Freezer for Camping, 🚗 Car, Truck, RV, Boat, Travel and Home – 12V/24V DC & 110V-240V AC by Neil Bodell

The thermostat is far from working. You have to set it at 24 or 25 ° to lower it to 40 in the fridge. It turns on and off perfectly and cools the interior in a reasonable amount of time. My biggest problem is that it is very poorly insulated. It can hold an internal temperature of 35°C all day long as we drive on our trip, but if you stop at a restaurant for an hour or let your kids run around in the park, the temperature will rise immediately. I kept a digital thermometer in the cooler, and with an ambient temperature of 70°C, the cooler went from 34 to well over 50°C in an hour. It's good to have a fridge, but it also needs to keep it cool when it's not plugged in.
