Not that Solar lights aren’t useful. They just don’t put off a ton of light. I had a handful of these solar units lying around and decided to take them apart and reconfigure them as a solar battery charger.
I bought the solar charge controller on eBay for less than $10 and wired everything together on a piece of coroplast.
I’ll probably improve my design a little and mount it to my daughter’s power wheel. Or maybe not. I kind of like the idea of having the battery charger be portable.
One of the drawbacks of my unit so far is that it isn’t protected against the rain particularly well. I could improve that if I wanted to.
