Switched to a hand-crank/solar flashlight about a year back, and it’s definitely more reliable than trying to keep extra batteries fresh. I also keep a small folding solar panel (about the size of a paperback book) that can top up my phone or a power bank if I’ve got enough daylight. That panel isn’t fast, but it does the trick for basic charging needs—wouldn’t count on it for anything too energy-hungry though.
Aside from that, I’ve added a lightweight water filter, some simple herbal tinctures (echinacea, yarrow), and basic wound care. Used to carry more canned food, but have shifted to high-calorie bars and dried fruit since it cuts down weight and keeps longer. For lighting, those little LED keychain lights are surprisingly handy as backups too. Haven’t had luck with those tiny hand-crank radios—too flimsy, so I’m looking for something sturdier, maybe old
