Hi, I've been looking online to try and understand how to build a solar panel cell phone charger and all the projects I've found either center around just connecting straight to the 6v 167mah solar panel found at radio shack or praying a USB charging control panel from a backup battery for the purpose of converting the power. In only one design did I see someone use a couple diodes to refuse and clean the power to 5v Nessesay for a USB. However, I don't understand how this would address the glaring current issue. As I understand, most phones require at least 1ah to properly charge. Is there a way to properly address the above issue with a transformer and/or combination of capacitors/transistors to get the desired current from just one panel or would I need more panels in parallel to achieve this desired result. Or, am I just completely misunderstanding the projects I saw online and am over thinking the situation. I am very new to this and I am trying to this project as a mental exercise to learn more. Thank you for any help you can provide in helping me learn this super complicated world.
