I mean, the running on watts vs volts part was nonsense.
But, did get quite close with the power calculation. Although here in the UK the average car battery seems to be around 60ah. I did see some very expensive large 105ah batteries. But they were definitely the outlier. So if you had a 100ah battery then it would be 1.2kwh with 100% efficiency.
Also, it doesn't mention that you'd need an inverter to make the fridge run from a battery. These also have inefficiencies which would reduce the runtime on the battery.
Was about to say inverter until I saw your comment. I think the robot meant to call out AC vs DC.
Not wrong, but the efficiency of inverters is really high, loss is just about negligible.
