I realized that we needed to upgrade and get new solar lanterns and light sources and a solar/crank powered radio.
Make sure you read the reviews of the hand crank powered lights & radios. I, along with many bought some hand crank flashlights from
Amazon that received hundreds of rave reviews. Many people tested the flashlights right away. Left the bright flashlights on overnight to drain down the power, then cranked them right back up. Flashlights were bright again. Worked great.

So those reviews for
initial tests & usage were rave reviews.
What none of us knew was that there were little watch batteries inside each flashlight creating the power. Apparently, as long as there was still a
little power in each watch battery, the crank could recharge them. BUT, if the flashlights were left in a drawer for a year or so and the watch batteries totally drained of power on their own and were TOTALLY dead, NO amount of cranking could generate any power.

These flashlights were useless when we actually needed them.

And why bother to buy a hand crank light that depended on batteries anyway?

Especially little batteries that were hard to remove and change?
Hopefully, there have been newer hand crank and solar powered items developed instead.
While I may still get a hand crank light, I decided to go the route of getting LED lights (that are quite bright for a long while yet use very few regular batteries. I've got re-chargeable batteries now. The newest generation of NiMH rechargeables say on the label that they are “ready to use” right away. Brand new, they have a shelf life of 5-10 years. No need to charge first. Once charged, they last at least 8 months to a year without being recharged and still retain 80% power.
I bought several extra that are kept reserved only for emergency use, so I do not have to go raiding items around the house for batteries to operate stuff. And enough to keep things lit for a week. I set a reminder in my calendar to remind me to charge these emergency batteries twice a year, once before hurricane season, and then in the winter before the blizzards & nor'easters start here.
The only thing I would like to get is a solar powered cellphone charger. The technology keeps changing and growing on that, so I keep putting off getting one.
