I have 4 of those Lii-100 chargers, they have usb outputs on them. Then I got some of those flexible USB lights, you can get a 5 pack for like 6 bucks or something. Then I just use a high cap 18650 or 26650 in the charger with one of them lights in the USB port. Will run for days. Everyone has one in their room and there is a flashlight in every room too. I’m sure there are better ways, I just already had the Lii chargers on hand.
