I just hit this for basically free. My idea is to let it charge up some power banks for free using the sun.

Do I need anything else? Some things I read mention getting a regulator to make sure it doesn’t go above 5volts. Is this necessary? Likely need to leave it plugged in for days or weeks for larger power banks like 20,000 mAh

Some people mentioned in low or no light and plugged in, it will actually draw power out of the device it is plugged in.

I don’t know anything about any of this. Looking for your wisdom.

I have a small panel like this. It came with a chinese camelbak [pack]. I can't speak to how well it works though really since I haven't had to depend on it. I did test the output in the past, but I don't recall what my values/results were. Could look at it again.

I don't think its going to charge much at all in a matter of hours.. you would want a couple of 100w panels for that at least.

I’m not worried about hours. Can be days or weeks. I just think the idea of charging up my power banks for almost free (I’m $2.85 in right now) is cool.
