Is this Ecoflow portable fridge reliable? A very thorough review

Today, we take our brand new portable fridge on a trip! We have purchased an EF ECOFLOW GLACIER Portable Car Refrigerator and we take it on a seven day trip going into hot and humid climates such as Atlanta, Ga and Orlando, FL.
During this trip, we attempt to do everything you'd want to with the fridge, run it off battery, recharge it in a vehicle, store food and drinks. Take it into and out of hotel rooms. We even test the ice maker.
This purchase came out of our own wallet, our own budget, and was not endorsed or asked for by anyone. This will be as close to a fair and accurate review as we can give.
Is Ecoflow Glacier Portable Car Refrigerator worth it? Can this product actually save you any money?

The cooler has to have wifi for the app to work, but if it has wifi it will tell your phone everything, including when ice is ready, any time your phone has cell signal. I kept getting random messages that ice was ready while working.
