Simzlife 12 Volt Car Refrigerator, 80QT(75L) Portable Car Fridge with Wheels, 0℉~68℉, 12/24V DC & 110-240V AC, Black

Does the cooler stay on while being unplugged? Or do I have to keep it plugged up in order for it to work?

With only two weeks worth of semi-truck that I have recently purchased, frankly, the value is definitely worth that expensive price tag. Small size and limited space, but its durability makes me feel it's worth the money. The actual temperature was a little lower than what is shown, which satisfied me. And its energy saving performance is very good, there is no problem keeping drinks and food at the right temperature. Better yet, if you want to use it as a refrigerator, that's totally fine too. It's not perfect, but it's very close.

The equipment temperature control fails and continues cooling after reaching the set value. Despite being connected to the power supply for several days, the F1 frequent fault code, forced reboot to return to the normal temperature display. Poor insulation leads to the inability to stably maintain the set temperature. The device starts having problems after 30 days of complete purchase. It should be considered with caution.

I purchased this product to transport frozen blueberries from my home in Maine to my family in Georgia. After pre-cooling them to -4°f, I packed them into 14-quart ziplock bags and placed them in the car. Electricity via cigarette lighter socket, one way south. Upon arriving at the motel, I plugged it into the wall outlet and put it back in the car the next morning. After three days and two nights of transportation, not a single blueberry thawed. During movement inside the vehicle, inside the room, and outside the vehicle, the temperature rises a little, but never exceeds 16 degrees Fahrenheit. Most of the time it stays between 0 and -4 degrees Fahrenheit. You can adjust the temperature to keep above freezing. I am very satisfied with the performance and it fulfills the purpose I bought it for. I highly recommend if you are looking for portable refrigerators or freezers.

I was trying to use this refrigerator to keep the camper cool. The temperature dropped a little during the first test. I thought it worked and turned off the power temporarily. The result was that once I put the refrigerator in the car, I realized that it had been consuming power, causing the battery to die. After lowering the temperature, it still can't stop working, obviously it can't achieve the cooling effect.
