Someone who loves me, who also came up with our family motto, "Excisto Paratus", bought me a Big Blue Solar 28 watt foldable solar panel, about $70:

Separately purchased was a battery charger for AAA/AA/C/D/9V cells/batteries with a 12 volt input that plugs into the solar panel. about $20:

For the reason that it will run off standard or rechargeable D Cells, I like the UST 30 day lanterns ($40): https://www.amazon.com/UST-Portable-Life...23327&psc=1

UST also makes lanterns that will run on AA cells.

I also have a couple of the LUCI solar lights, available at Sierra Trading Post and other sources. I just leave them deflated on our south facing window sills, for continuous charging and ready access. I've given them as gifts to our children's families and they have been much appreciated when the power goes out, or for camping: https://mpowerd.com/collections/our-lineup
