Can you power a USB port by just a solar panel without a battery? Let's find out. I'll also show you another (easier and better way) to do it by using a 20V to 5V regulator. • Here's the link for the ebay search for the solar regulator. There are 3 versions of this board where 3 different capacitors are used: Electrolytic, Solid, and Ceramic. If you use it a lot, I'd recommend using ones with solid or ceramic capacitors. • https://www.ebay.com/sch/i.html?_from... • The apps I use to measure current on my phone are Charger Tester and Ampere Meter Pro . These are for Android OS only.
