EDIT: I have been in touch with the manufacturer regarding my challenges with the ICECO 37QT VL35ProS Single Zone Portable Fridge Freezer and we have come up some solutions so I want to amend the review. I was able to change the thermostat I was using for the testing as well as using redundancy by using a laser thermometer. The temp sensor in the fridge matched what the digital display was reading so it seems to be all good. The customer service has been fantastic.
I have been putting mine through the test today and what I have found is 1. it uses way more energy than advertised. For these tests it is stationary in my room which is about 78ºF. There are 3 Nalgene bottles with water (everything in the fridge has been previously cooled down), a couple of protein drinks and a energy drink. I cooled the fridge down using AC for about 45 minutes. It didn't cool down in 15 minutes as advertised on 'max mode'. After that I hooked it up to a 12v source using a Ecoflow River Pro. Over the course of 7 hours I have opened it about 5 times with each time no longer than about 10 seconds. I had to check the temp inside...which leads me to my next gripe.
The thermostat is way off! I tried using 'max' and 'eco' mode and when the fridge reached the set temp, I opened it and it was about 4 degrees off. For example, I had it set at 34º and when it said it reached that temp it was actually 38º at the bottom of the main part. The smaller deck was about 10 degrees warmer. I put a laser temp on the items in the fridge to verify and they were warmer than the ambient temp.
There is no Bluetooth on this model for some reason which is really too bad considering the price. It is also pretty heavy for being only a 37qt model.
Along with it using a lot more.
