What specific use case would you be using that for?
Besides something like camping where you can charge before you go and use it to keep some lower-power devices like cell phones and flashlights charged I can't really see where it'd be useful. It's not big enough for a job site or home backup power, and really just doesn't compete well against even much, much cheaper gasoline generators.
Lots of energy/climate change conscious people use < 10 kWh per day, 1 kWh battery buffer for small solar would do quite a lot, you'll know you can always charge ebikes and gadgets, etc.
