I have a portable solar charger and a small hand cranked generator and use them to charge a portable Power Bank.
The only problem is I want o see how full the battery is at any time. It's connections are USB 2.0.
Would anyone know of a small gadget used specifically for this kind of thing. I've looked on the web and it seems they all start at 12 volts when I need on which will go as low as 5 volts.
I want something like this: https://ae01.alicdn.com/kf/HTB1ngvL...m-battery-coulombmeter-voltmeter-electric.jpg with the percentage and the level bars.
I was hoping to find something already made but if it's not too difficult I could easily make a USB version providing I could find a meter like this which matches the voltage I want to test (USB 5.0 volts I believe).
I know there are plenty of these things: https://c.76.my/Malaysia/[email protected] but this is not what I'm looking for.
Any suggestions?
Thanks
