It will last a few days with mine.
45 watts is .375 amps at 120v. So I'd estimate that a 4ah 18v battery would run this cooler for about an hour.
Now if you have a 4ah 40v battery and the 40v inverter instead. You just simply double the estimate to about 2 hours.
Now if you're a weirdo like me with an electric lawn tractor I have 8 8ah 60v batteries. Each one of those would last around 6 hours. But that'd be a lot of batteries to tote around and definitely not worth it cost wise if you didn't already have the batteries.
Note. I did all of the math on this in my head and then estimated low because you lose a bunch of power due to the inefficient inverters made for these batteries.
A better/cheaper more logical thing to do imo is to get a 100 ah 12v lifepo4 which would give you ~10 ah at 120v which an efficient inverter and a 100w solar panel to charge it during the day so you can run it indefinitely(theoretically). I got a 100ah one from Amazon, the brand was vatrer. I saw a breakdown on YouTube and decided this was a good battery to get. That being said the cells are probably b grade. But I don't care about that since I'm only charging it 20 or less times per year since it's for my trolling motor on my boat.
Sorry for the long winded post! I just had been looking at those Ryobi inverters for a while since I have a bunch of batteries. I think it would be fine if you have a few batteries and are only using it for like picnics or situations where you only have to run it on battery for short stints. Definitely not for a long camping trip in the woods unless you have some way to constantly have some charging.
Wattage may be fine but the pure vs modified sinewave might be of issue.
On another note, I had a backyard party the day after finding this thread but didn't bite. I spent over 20 dollars on ice...
