I have a lot of 18650 batteries lying around, so I ordered a bunch of USB step-up boards and designed this small but powerful charger.
Current iteration is #12, so I spent some time to make it more or less perfect
Model is perfect fit for this USB boost converter and even for a bit longer batteries.
Use a spring terminal in the deep end, wire should go in a long groove on the side
Excessive wire can be stuck under a PCB, just make sure that micro USB is fit in it's slot first.
