Well my phone (that’s almost always within reach) had a light that can get me to the next more permanent one. We have these stashed all over the house and cars. They are remarkably strong! And we have a couple of lanterns - both battery and an oil lamp that we use. We lose power a least once a month. One month recently we lost it 3 weekends in a row. We are used to that.
I’ve got plenty of battery charges too that are always full. But honestly I’m more worried about a banking collapse than anything else. But not so worried it keeps me up at night.
