Many people made their own DIY Solar Charger but never actually measured and tested the performance. Current as low as 0.10A could also trigger the phone charging signal (however it might take days to fully charge it. Bad examples will lead you to lose passion and interest on Solar Projects…..
Besides wattage, the voltage value plays an important role in DIY Solar Charger. Enjoy the video and happy DIY !!
