I have not had a chance to use this yet but I have plugged it into my power station and tested the refrigeration and freeze functions. I had the left side set at 36 and the right at 0 in 53 degree ambient temps. The app worked as designed and I was easily able to set the temps. It took less that 30 mins for the left side to get down to temp but then it kept going lower. It eventually went below 32, which would have started to freeze things on the refrigerator side. That was concerning. But once the freezer side reached its set temp, the fridge side began to come back up and seemed to be leveling out. This was after about an hour. Both sides were empty and I didn't leave it on long enough to see if the correct temps were maintained.
There are two things that I think are a problem with it. One is that it is a large unit that does not have wheels so it is very cumbersome to move, even when empty. I can't imagine how you would move it, full. It's not a problem for me as I intend for it to be stationary but that's a heads up for someone looking for a mobile fridge/freezer. The other large area of concern is that it is advertised as having a battery port, which, with a separate battery pack, would allow the unit to be powered remotely when there were no electric hookups or power banks. But no one was able to advise which 12V batteries would fit this unit. When the question was asked, VEVOR only answered that the battery was not included. I reached out to customer service and when they finally got back to me, they directed me to some bizarre page where the minimum order was something like 100 and shipping charges alone were nearly as much as I had paid for the entire unit. When I reached out again, after some time they offered me a discount, which I accepted. But they never came through with a link or order info for the battery to be used with this unit. If that's something that is important to you, this is something you should be aware of.
