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_ so after a hard days work you had a like warm 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!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_ go flat and a USB port on top so you don_ 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_ been plugged into the car now for over a week and I have found that for me i set it to -1 (checked with calibrated temperature probe) this is cold enough for my drinks and at the same time also makes ice cubes in the car at this temperature. Yes I am able to make ice In the car!!So far it has not cut out due to a low battery and the car was sat all weekend from 3pm Friday until 8am Monday with the fridge plugged in and running. As it_ a proper compressor driven fridge it only runs when needed to keep the temperature stable. So uses very little energy once the contents are cooled. It is also capable of going down to -20 so you could even put ice cream In instead (only has the one compartment so everything will freeze) but just imagine sat in traffic on the M25 in sweltering heat and you pull out a magnum ice cream for everyone in the car. The looks on other drivers faces would be priceless!!! But seriously yes it_ a lot of money initially but it is a proper fridge/freezer so come Christmas you have extra storage for food or drink. Summer bbq on the beech you can fill it with drinks or what ever and with a 10000mah power bank i
