This old diskette box is a perfect fit for my latest solar charger / regulator.
The regulator supports solar cell under 1Amp, and charge 12V battery. In a normal day it charged a free maintenance lead acid battery of 1.2AmpH for just under 2 hours, on a solar panel rated 12V~18V 10 watts. I used this battery on a 3 watts LED flood light, and it lasted a few hours, enough to light up my hall way.
It can also be used to trickle charge a 12V battery, using a small solar panel (lower voltage) as long as not exceeding 1Amp. A small wind turbine also be used a power source.
