Started testing this the day I got it. First thing I wanted to know was how long it will run on my small battery bank. Mine is 40ah, which is fairly small. Fridge was left in freezer + fridge setup. Temps set to 0° and 40°F respectively. Ice cream bar in one and 1 can of beer in the other. Tip: filled up will be more efficient. Ambient temp was 70°F. With battery bank at full charge (13.4v) it ran for 50hrs until battery drained to approx. 50% (12.1v).....with no charge of course. Was only hoping for 24hrs so I was pleasantly surprised. This means with solar charging on my battery even at low efficiency I'll be able to keep fridge running continuously no problem. Also tested in fridge only mode and even more efficient, as expected.
The volume is obviously not large but considering how many items (bacon and beer) needs consistent refrigeration, this fridge will work perfect for my needs. And size is also perfect for both in cabin (backseat between 2 passengers) and truck bed. Building a vented weatherproof crate to protect from the elements....more on this later.
Having the fridge app is really convenient. Another reason for choosing this model. Works great for controlling/monitoring. Only complain is needing location service turned on, makes no sense to me. And instructions for setup makes no mention of that requirement so had to experiment to figure that out.
Overall, I'm impressed. This looks to be a very capable little fridge.

Excellent portable fridge/freezer combo!!

I gave it as a gift to my son and daughter in law. They ae thrilled with it. They were extremely impressed wit how quickly in pull down to temperature.

I have done a few test on the GO20 and have been very happy how it has worked.

Plug it into 120V and it works. We haven't thoroughly test it yet, at first impression it looks like a good quality unit
