Review on Goture 20Qt Portable Car Refrigerator/Freezer | RV Fridge Auto Cooler [Fast Cooling: 40 min from 77℉ to -7.6℉] | Perfect for Truck Vehicles, Camping, Boating, Travel | 12/24V DC Available by Miro Dadee

There are two types of these devices: compressors and thermoelectric coolers. The compressor type is the most common and versatile. Such a refrigerator provides more efficient cooling and lowers the temperature much better than thermoelectric models. In addition, compressor refrigerators offer more storage options and have a larger capacity. However, they generate more noise and vibration. A key benefit of thermoelectric refrigerators is energy efficiency as they use very little electricity. In addition, thermoelectric models are quieter, have less vibration, and are typically lighter than compressor-based models. If you look at it, it doesn't look like it won't work with a cigarette lighter, but it definitely will. This is a great portable camping fridge as it can store food for a couple of weeks for a family of four or five. It has three battery levels, but it seems to me that it is best to only use the lowest level. In fact, I don't really like the high battery setting as the device turns off almost immediately after connecting to the battery. Once the temperature you set is reached, the compressor barely runs, which means they've greatly improved the insulation on this model. It can go as low as -7.6°F, which is ideal for your freezing needs. It perfectly protects frozen food from spoiling, especially on the go. I don't particularly appreciate throwing away food, so I figure if I can't find a campsite to plug in and have frozen food I don't want to throw away, I'd just use its 12 volt DC power. Power supply option when I use it in the car. Honestly I bought it for my office to keep my energy drinks, bottled water and groceries cold. It doesn't take up much space and works as expected.
