Alright guys, so...I'm super new to all of this...other than basic circuits in physics. But, I'm trying to make a solar panel charger...that charges a 3200mAh batt and I'm wiring the two solar panels I'm using with a Mini DC-DC Voltage regulator.
These are the parts of using:
Mini DC-DC Voltage Stabilizer/Regulator Module

2X All-powers 2.5W 5V/500mA

Anker® Slim 3200mAh Portable Power Bank

So I'm using 2 solar panels so I can get a max of 5W(Is that even possible with the panels though?)
I was thinking I could hook the positives of both panels to the + input of the regulator and hook the negatives of both panels to the -input of the regulator and a stripped microUSB(to charge the battery) to output side of the regulator. Then I plug my phone into the USB on the power bank. Would this work?
Also...another question I have is with the pot on the regulator....its a small blue screw type one that i can turn. I had to turn it many times before I finally heard a click. Now with every full clockwise turn there's a click? Can anybody tell me how to measure it?(Does each click indicate a increase in voltage? Or does the click mean that it's returning to a minimum, and right before the click is a maximum?)
My last question is: I originally was gonna have a USB hub connected to the USB port of the power bank and do my charging through that, but wouldn't that be much slower than straight from the power bank?
I got my ideas and guidance from this guide before coming here :

Thank you very much if you take the time to answer.
