I looked up the page and it gets worse.
You will need to shop for a car inverter. Find one that is at least 1,500 watts, and it will help you power your refrigerator for up to five hours—usually without damaging your car battery. Considering how much food we keep in our refrigerators, a $200 car inverter is a bargain!

It hurts.
While reading the question I thought: "That's not how Watts work", but then this "answer" hit...
This post made me beat my head with a 2 by 4
Regardless of source, if your refrigerator is running you better go catch it.
Its stealing your food.
This reads like a shitpost. The math is eh, okay, but the explanations are totally wrong. I won't even try to figure out what "runs off watts" means.
Enough of any electricity source, using various converters can get any appliance working "technically speaking", but in the end the amount of energy available at the source and the rate of consumption at the end and any intermediates. So "technically" an AA battery can power an industrial electric press, but only for a fraction of a microsecond, using a lot of charge storing infrastructure and with a lot of changes to get the tiny bit of DC into the machine requires to operate, likely 3 phase AC power.
A proper explanation would say a lead-acid car battery provides power at around 12V and electric camping fridges nominally operate around 12V so you can connect them directly and operate it (so you can sorta say they both run off DC volts?). If not you would need a buck or boost converter. The available energy of the battery (Watt-hours is a useful unit here) and the consumption rate (in Watts) of the fridge determine how long you can use it on the battery.
Well on the bright side, these things will start learning from reddit. More garbage for us to chuckle at.
Watt-hours
how hard is it to just use joules 😭 the consequences of non-metric time are grave
i'm just kidding btw, i know why watt-hours are used
Saying "your fridge will run for 14400 seconds" isn't very intuitive for people unfortunately...
Licenced insurance agent. Not for long!
I thought America runs on Dunkin... (doughnuts)
No easy conversation from doughnuts to volts or amps. I give up. But with enough oxygen you can hear up pretty gud with a single doughnut. Then you could use a Stirling engine to pump heat from the fridge to the environment. Energy in a doughnut ~224cal according to Wolfram alpha. That's 940kJ. 940kJ/1hr~260watts which should run a fridge for 1 hr. However energy conversion is probably going to leave you with like 10% at most of usable energy so ~6 minutes run time. America needs a lot of doughnuts!
