I am a mobile engineer and so spend a lot of time In my car travelling all over and have a bit of a thing for cold Coca Cola! I have spent hundreds over the years on traditional thermoelectric (peltier plate) fridges. Every 12-18 months I would have to buy a new one as the fan would fail. The problem with the thermoelectric ones are they just do not cool down very quickly and use a massive amount of energy. I would spend time every evening bringing it in to plug in and put ice packs in the freezer to help keep it cool. I found that often enough that once the car interior temperature got really hot the fridge would blow warm air as it was only cooling 15-18 degrees below the car temperature that could be up in its 40’s so after a hard days work you had a lukewarm can of coke for all the effort and if you left it plugged in over night to the car you ended up with a flat battery. I ended up using a low voltage disconnect relay to protect me from flat batteries! (Although that’s another story as the disconnect didn’t work and still flattens battery!)I saw this and decided I had nothing to loose and was worth a try. I wish I had done this a long time ago. It holds about 30 cans of coke and cooled them down from ambient to 3 degrees in about 3-4 hours on my way to site. Even testing at home when delivered it took about 25min to get down to 2 deg whilst empty.So the fridge is the 22L version has a light in it, is well made the lid has a chain to stop it falling over backwards, the handles are built in and sturdy. The finish is nice and it even has an ice cube tray. It has its own built in battery protection so if you leave it connected to the car battery all week it won’t go flat and a USB port on top so you don’t loose complete use of the cigar lighter In the car.The fridge fits behind the back seat in my octavia but only just and I had to put a box under it to lift it up to fit (this is not a negative on the fridge) it’s been plugged into the car now for over a week and
