Review on Kohree 12 Volt Portable Refrigerator: Fast Cooling Small Freezer for Vehicles, Truck, RV, Boat, Camping - 26 Quart (25 Liter) Electric Cooler -12/24V DC & 110V/240V AC by Joseph Morris

1-week camping test in 35-degree weather. Chilled only to + 3 *. Neat but not -4*. Uses different capacities as needed. Used from 50 to 90 watts. Mine differs by about 7*. But I only measured in one area. I don't like touch buttons. I prefer something that really pushes. I used a 120w solar panel that only put out 80w to charge my Ecoflow. Solar energy was not enough to work around the clock. I had to use a generator to charge the green electricity. All in all it worked fine. If you want to keep a Yeti, Ecoflow, or other power bank charged, you need at least 200 watts of solar power, as this fridge uses about half the battery at night.
