TBF, it depends on the number of outages locally. In my area it is one outage every thunderstorm/snow storm, so unfortunately the up time of my laptop, even with the help of a large, portable battery charging station (which can charge multiple laptops at the same time), is not optimistic.
I sometimes fancy that I could just take cash, go into the wood, build a small solar array, collect & cleanse river water, and buy a starlink console.
