This is my first post here, so my apologies if it's in the wrong section. That said, I'm trying to find a power bank for the headlight system I'm planning to get for my bicycle. I have a set of 6 18650 cells that currently live in a USB power bank I use to charge my smartphone. If possible I'd like to get something that takes all 6 cells that I have, and can itself charge by plugging it into a USB adapter. That way, I can charge it easily without having to swap the cells into the USB power bank.
Can anyone provide recommendations for such a thing, assuming it even exists.
Thanks for any help.
