The below guy was able to turn a laptop battery plus circuit board into a hand-crank battery charger.
So my question is, since it can be done, why aren't hand-crank AA battery chargers available for sale, so I can buy one to recharge my Duracell NiMh batteries for use in my Cree lantern during blackouts?
..and maybe Eneloops too, if I get them.
