Sure, buy an inverter and burn up 10% of your energy in the conversion if you’re lucky. That inverter will cost roughly as much as the contents of a standard fridge + freezer, by the way :)
At that point just buy a well insulated cooler and always have some ice on hand. It’ll last much longer.
The question wasn’t “Is it efficient or cheap”, it was how much energy is in a battery, and if and for how long would it run a fridge. If you also want to add one more point to why you probably shouldn’t do it, car starter batteries don’t generally like to be deeply discharged, you’d want to get a marine battery for that use.
As for how much the inverter would cost, depends on the fridge, but Amazon has a 1000W inverter for around $85, that should be enough for most. Ours could run from a 300W one, they cost around $30. Pretty handy devices if you want to run any kinds of electronics from a car anyway, I have one for when I want to charge my laptop and RC batteries on the field.
No it doesn’t. Watts do give a shit what percentage is voltage vs amps. You have to convert between AC and DC as appropriate as well as ensuring the voltage of a 12v battery is stepped if needed, but the watts are the same in any case. (Not figuring for system losses)
This argument is equivalent to saying you can run a fridge off of gravitational potential. Sure, energy is energy. That doesn’t make it remotely practical for the average person to use that form of stored energy, you absolute wet paper bag of an overly confrontational putz.
You should Google what a step up and step down transformer do. It’s very simple and easy to prove you’re a dipshit once you understand you’re arguing from bad faith trying to compare a simple bit of circuitry design to hydro power.
You truly are a dunce, this doesn’t prove your moronic “watts don’t give a shit” comment. Let me explain this to you slowly.
Great job! Your “3 seconds of googling” solution burns ~20% of the stored energy in your battery in conversion losses. You just went from running an average DC fridge for 3-4 hours to running an average AC fridge for 2.5-3.2 hours. By the time you run to the store to get one of these, get back, get it installed, and cool the fridge down again – the milk has gone bad. Congrats.
I never said it was impossible do convert DC to AC. You made that jump all on your own, in bad faith, because clearly, once again, you’re an overly confrontational putz.
Sorry you live such an unfulfilling life that you do this to yourself. It’s been a good laugh for me though. Maybe read a book on the subject. Have a great day :)
We are talking about whether it’s possible to run a regular fridge on a 12v car battery. Not if it’s efficient lol. You have to convert DC to AC because that’s part of the problem, so yeah I made that jump all on my own lmao
You’re a troll, but there’s no rustled jimmies here… You’re too obvious.
Your comment was ambiguous, stupid, and designed to ridicule. If you are attempting to imply inverter and other loss then be more specific. Regardless, the comment you were referring to already provides arbitrary values that you can assume include loss.
So please explain to me what the fridge being 12v DC or mains AC powered has to do with anything, when an example uses arbitrary power and energy values? I’m genuinely curious.
Also assumes that the average fridge runs on 12V 😂
Watt hours are watt hours. Sure the compressor won’t run on 12 volts as is but the energy is there, just needs a converter.
Fwiw, our 15 year old fridge uses around 1000Wh per day.
That’s a big joule thief

Go ahead and prove it then :) if it’s so very simple and easy

3 seconds of googling like I said

I said “you better hope it’s 12V” and you jumped to if it’s possible. You’re an utter moron :)
Energy is energy, you are not an electrical engineer.
Congratulations, this is the worst attempt at ridicule I’ve ever seen
