There is announcement in the local news here in my place that there would be a rotational brownout coming and my town is on the list. Other towns and cities already had their turn and I do not know when my town's turn would be at.
So I am just recharging my powerbank now which can power my minifan for many hours before getting depleted. I thank God about this battery system because it saved me a lot from inconveniences of discomfort at my dialysis when the room gets hot or the dialysis center's airconditioning gets loco on the patients, my powerbank is on the rescue.
The weather in here now in my country is so hot as hell so people are resorting in buying airconditioning system which takes a lot of power and thereby depleting the power reserve. So in other words there is so much demand for power but so little power to go around.
Their solution is to cut power in selected areas for about three hours to lessen the load on the power grid. Now I just have to have some working mini fan at least to help me when the power is cut off.

My hearing issue is still my health issue and it is maddening if I would not have something to deaden the ringing sound like the humming sound of a working electric or minifan. Plus of course it is really humid and hot even in the night so having my powerbank ready will keep me comfortable until the power is let out again.
