I made a set of small solar gadgets which included a USB powerpack, solar capable radios and a rechargeable flashlight. I made some improvement to my powerpack by adding another small solar panel. I tried to add a charging indicator light but for some reason, the zener diode with the 5.6v breakdown voltage didn’t work at that voltage. I will research this and come up with a fix.

Solar powered TV. only 25 watts runs it. this tv can easily be run using a small solar power system. another great way to go solar. my video titled, “how to hook up solar panels (with battery bank)” shows exactly how to put the system together
