The typical 100 amp alternator will burn out in as little as 20

Like I said, you have to know what you're doing.

You never pull 100 amps.

Typical fridge pulls 3 amps running the compressor.


Not the typical fridge in the last 3 decades. Before replacing
my old Frigidaire I used a Kilowatt meter to measure it. It
pulled 180W. The new replacement pulls 90W. I also saw similar
~90W number from a 8 year old fridge and also a freezer at a friends
house during Sandy.





That's 33 12v amps, assuming 120v AC, but only when running the

compressor.

More like one quarter to half that.




Throw in some amps for lights, you're still ok.

It's a viable emergency power source for some folks.

Plenty of examples of people who do it.
