Portable hydropower Answered
Hi! I am in a senior in high school and am required to do a project as a part of my stem class. I am planning to make a portable hydropower power bank that someone could use when they're camping to charge their mobile devices. The problem is I don't know how to go about actually doing this. I was planning on making a small stator and rotor for my generator but after further research I found out that I could use a motor and a diode instead. Any help on which would be better would be greatly appreciated. I also am confused on what type of battery to use(it will be inside my device and will be the power bank for charging devices). I was planning on using a 5000 mAh, 5V lithium polymer battery, but am not sure where to buy one(If u just search 5000mah 5v battery, the responses come up with 3.7V. I will also need at least 2 usb charging circuits. Honesty any guidance in what I should would be helpful. Thanks!
