Will’s VAWT wind powered generator will be able to charge a battery in the battery pack while the battery pack is connected to the diode which is connected to the circuit board with the USB cable plug. My solar panels may be able to be connected to the same battery pack, but powering different batteries. This way, all four of the batteries would be able to have power and power the circuit board that is charging the phone. Another option would be for Will’s VAWT and my solar panels power two different battery packs which powers two different circuits, each generating 3 volts. But the problem would be to somehow connect the two circuits and then charge the phone as the phone only allows one cable to be plugged in.
