Review on 🍺 USB Mini Fridge for Beverage Drinks - HQF Portable USB Powered Cooler & Warmer Car Refrigerator for Cold/Hot Drinks (Red) by Darby Perkins

Connected immediately upon receipt and happy with the purchase. I had an energy drink in the mini fridge and it kept it cold all day. They usually keep you warm because it takes me a long time to drink them. One thing I noticed is that the info says 1 line is cool and 2 lines is cool, but actually it's the other way around. 1 line is used for heating and 2 lines for cooling. As for the light he's talking about, I haven't seen it. NO instructions included!
