Are you serious? Everywhere I have stayed has both UPS and a generator yet you most definitely do feel it. UPS will only run the lights and maybe a fan or two. A generator allows some AC but anything like an iron or kettle will overload it.
And unless you are very wealthy, you’re going to feel the pinch of running a generator especially in the summer.
Like eastern said, a lot of the time, the UPS doesn’t even get to charge. And as Gina has said, the load shedding is extreme in 99% of areas.
The lack of electricity and the heat are problems that people who have lived there all their lives (like my inlaws) find it hard to cope it.
Anyway, reading your next post, it seems like you have the kind of life there that a fraction of a percentage of people have. Hardly typical life in Pakistan.
