Hi guys! This time, let's make a DIY Solar Power Bank based on DFRobot modules and parts, with a folding solar panel, battery capacity indicator, and builtin LED lamp! You even have the ability to hook it up to a solar panel on your own backpack and charge your smartphone on the go!
With a relatively good phone charging speed of about 3hrs, this homemade power bank is quite capable.

Power output/charging time calculations are all mentioned closer to the end of the video.
