Review on Dual Temperature Control Portable Car Refrigerator 48 Quart(45 Liter) 12 Volt Cooler Mini Fridge Freezer For Travel Camping Fishing Outdoor -12/24V DC by Eric Avina

Great Buy! My wife and I can only operate it around the clock with our solar system (GZ Yeti 1400). The price is really affordable and the quality is excellent. We could pack groceries back and forth for a week, sometimes a little more, it's not big but there's enough space. Consumes very little energy as it is a compressor fridge it is very efficient. I tested it and ran it in my truck at 90+ degrees for over 24 hours without starting the truck. Inside everything was iced up and the next day the truck still started. That being said, every car and battery will be different. I wouldn't advise longer without charging the battery. The design is very similar to other products on the market and the quality is also very similar. No problem. I've read reviews where people complained about the noise but I totally disagree, it's not quiet but not loud at all! Hope that helps. An updated 1-year review is published here
