I have this fridge freezer that works 24/7 works surprisingly well. I put igloo ice packs in the freezer and fridge compartments to fill the space when it's not full, which can help it work efficiently as it keeps the freezer side temp at zero, plus or minus 3° , and on the refrigerator side , 37°, plus or minus 3°. I run it from a Flash Fish G 300 power plant when I'm not near standard household outlets, and when I'm at home I run it from a power supply plugged into our house. I also plug the power pack into my 750w inverter that I got from the cargo shipping at the port while driving and it only takes about 60w of available power. Once the car is running and you're driving, you can run it from a 12V car outlet or a cheap 100 watt inverter plugged into a 12V outlet car starts. So I bought a Flashfish G300 power station to run my fridge/freezer off something other than a car battery. I have since upgraded my power station to Rockpal's 500 watts. This fridge freezer is quite amazing, I haven't tried it in 100 degree weather or 100 degree heat in a car, I'm sure it will be difficult but for me here in Southern California and traveling in the Sierra Nevada, In town, at school, at work or at the beach where our temperatures reach the highest 90°, this fridge freezer works great. We can always have cold drinks, food and ice cream! I also picked up an Accurite Remote Temperature Reader, a dual unit so I could monitor the internal temperature in both the freezer and fridge compartments. I put lithium batteries in two of the transmitters because regular batteries are no good in the fridge.
