We now have this Mobicool coolbox for several months and had extensively especially during a three-week camping holiday opportunity to test them. During the holiday we used the box as a handy fridge in continuous operation, while driving and during short stops Park (3-4 hours the car battery creates problems) through the 12V connector, in the state with the 220V connection. And we are completely satisfied with the device today. The workmanship is good, both connecting cables have a good length, keeping the cable in the cover is also well done. The exterior pocket and strap like us well, the second cover (without cooling unit) we've rarely needed, but he has the advantage that several 1,5l bottles fit with him in the box, the lid with cooling unit is only space for 2 such bottles. The box also cools sensitive foods such as butter or meat enough. She is relatively quiet, we even have a few nights sleeping right next to the box. Also for cooling drinks for parties or swimming trips the device is well suited. We can not say anything yet because we have not yet used on the hot stop function. Overall, the box is thoroughly recommended, in our opinion. The in comparison to other devices slightly higher price is justified, we would buy them again at any time.
