Tl;dr: Are putting Li-ion batteries in a Wind-up flashlight a thing? If not, what options are there for a more reliable, renewable light source?
Hello, I'm a Paramedic, husband and father of a small family of 3. We don't make much money and live in an area where we are often heavily impacted by storms, severe weather, due to living in an old neighborhood in a forested area with above-ground power, as well as civil unrest due to covid and stupidity. I'm trying to improve our families emergency preparedness as we have repeatedly had real emergencies crop up leaving us without power, water, or food for 5-10 consecutive days, multiple times this year. During this time, i pulled out the old wind- up flashlight only to find that the old nickle metal hydride batteries would no longer hold a charge. Though I recently ordered a generator, I couldn't afford a very large one, and I still need a way to power lights in rooms that aren't powered. So I looked to find some wind-up flashlights that used Li-ion instead of Ni-MH but came up empty.
I am admittedly of a limited education and am not familiar with the quirks of different battery types. Is it not possible to engineer a wind-up Li-ion flashlight?
Please help me understand, I wouldn't be bothering you guys with my (most likely) infantile questions, but my family's wellbeing is on the line, and I don't know anyone who has knowledge of this subject.
Thanks in advance.
