For the uneducated, what’s wrong with it?
Watt and volt are two different measures for electricity. Also your fridge will not work when hooked up to a car battery for many other technical reasons, including differ t voltages, and current types (AC/CD, not the band)
Unless you have an electric car that can do vehicle to load. That means that you can plug in regular household devices like your fridge.
That vehicle isn’t using a traditional 12v car battery for that. Also the point t is you can’t connect a car battery to a fridge and expect it to work.

You’d need an inverter in-between, yes.

But for the record, inverters have been in gas cars with plain old 12V batteries for years. But you’ll need the engine running.

Yes. That not the “use a12v battery” assignment. It would be use an inverter…
The only way the “uncle” is correct and the only way a 12VDC battery is getting connected to a regular, 120VAC refrigerator, yes. And what most inverters run off of.
