Here no one shows up either and we have blackout frequently. It damages the electronic machines/items. I have always bottles and a bucket filled with water, powerbanks and a jumpstarter (with light and bigger powerbank) plus a mobile router (my son takes it with him now so he isn't too bored at school and can call me.. unless the wifi signals are gone again.
My biggest worry is no water. I can always write offline and travel 30-40 minutes to visit a library to post. I did that for many years.

I am happy to hear the problem is solved.
A happy day to you.
