Review on BougeRV CRPRO 21 Quart, 12V Portable Freezer For Outdoor Adventures: Keep Food And Drinks Cold Anytime, Anywhere! by Matt Williams

The electric cooler/refrigerator allow you to store drinks and food on long trip without needing to buy ice. It has cool features like battery protection to turn itself off so not to drain the battery. It also have Max and Eco mode to use less energy.It comes with DC 12 V car plug and a 110V transformer.I plugged it in using the 110V transformer at Max energy mode and in 20 minutes, it got to the 30* F that I set. However, even at the Max energy mode, I noticed that the temperature reading fluctuate up to +/- 4 degrees.For example, setting the cooler at 30* F, I would see it goes to 34* F before turning on and then stay on until the temperature reach 26* F before turning off.The e-cooler is fairly quiet but you can definitely tell when the compressor is on, there is a little humming.But overall, it works for its intended use.
