I’m really pleased with the VEVOR Car Refrigerator. It’s a lot quieter than I expected, hardly know it’s running. I used it for a 2 week trip running it off a leisure battery and 100watt solar panel. I set the fridge temperature to 4c and it seemed to maintain that temperature with out any problems during very warm weather.I was originally concerned if 20ltr wouldn’t be big enough but this wasn’t the case. You can easily store a 2ltr bottle of milk standing up leaving ample room for all the other essentials.The build quality is very good and it is easy to use. It also has an excellent function that will monitor the condition of the battery and prevent it running the battery flat so avoiding permanent damage to your leisure battery. It does all so come with a 240volt adapter, which was an optional extra on some other makes.I haven’t found anything negative about this fridge as it is perfect for my needs and works better than I expected.It is fairly large due to the compressor and requires good ventilation, so some consideration needs to be done about where you will place it in a car or day van.
