If a power outage occurs I mainly want to power my fridge and outdoor garage freezer.
My fridge: https://www.lg.com/us/refrigerators/lg-lfxs26973s-french-3-door-refrigerator
This is the battery backup that I’m considering: https://a.co/d/38ZaTlv
Do you think this will keep these 2 appliances up and if so, how long can it keep it up for? I was looking at this option as it seems less maintenance needed compared to a generator.
If this is not a viable backup solution, can you recommend me something in the same price range (under $600)?
Is this sufficient in the event of a power outage?

I’d say it’s far from sufficient. It may be able to run your appliances for a few hours, potentially even shorter, if its a hot day.
Large appliances probably use 100-200 watts each on average. So 1024 watt-hours will give you between 2.5 and 5 hours’ worth. Compare that to the freezer probably being able to hold its temperature for a day or so.
The battery is fine for camping trips when you need to charge devices, power lamps or run a small cooler. But not household appliances.
Look for a dedicated household battery, like Tesla power wall. Something too large to carry, and that has to be installed by an electrician.
Or, better yet: a small generator.
This is absolutely fine for an emergency, a fridge has a duty cycle, it will not pull full power all the time.
1kwh should last at least 12 hours if you have a modern fridge. Maybe 24 hours.
More if you reduce the cooling setting.
More is of course better, but If you want your food to not spoil in a weather emergency, it’s a decent option for the price.
2kwh is the sweetspot in terms of price though. I would see if I can spend a bit more on a larger model.
But to écho the other person, having alternative power such as solar and a gas generator is best. Having both is much better than just a gas generator being on all the time.
