I’ve been playing with solar power. So far my equipment only consists of an EnerPlex Kickr II Plus solar charger and a couple of batteries. Most days the EnerPlex sits on my dashboard charging one of the batteries, which in turn charges my iPhone in the evenings. My system is not perfect and we sometimes get rainy stretches, but for the last few months solar power charged my iPhone more times than not. As a friend of mine put it, “every little bit helps”.
I’ve also used this system to also charge my FitBit and iPad. Eventually, I’d love to expirement with more solar panels and bigger batteries. Prices have come down and I put this little system together for under a hundred dollars. More to come as I continue to expirement.
