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 John Ghattamaraju

Portable freezer works great. Direct current can be used. DC cable included. I tried freezing a cup of water overnight and it worked fine. The entire chest measures 22 x 12 x 11 inches. The size of a compartment is 13 1/2 x 9 1/2 x. I tried freezing a cup of water overnight with AC and it worked fine. I set the temperature to -22. The maximum temperature is 10 degrees Celsius and -22 degrees Celsius for a negative result. I haven't tested durability, so I'm giving it 4 stars. All in all it worked fine. I'll revise my stars to 5 stars after 3 months of continuous use if that doesn't let me down.
