This is an awesome design. I had trouble printing it and didn't have any battery mount parts. Also I wanted something smaller and lighter. Inspired by your design, I made this which takes the same charger and is designed for direct soldering.

18650 Simple Portable Charger Bank

Is it possible to make this using a Larger battery? or maybe Two batteries?

Hey! Can you please link me the CAD model of the 134N3P charging circuit (The USB board) I cant find it anywhere! Thanks!!

Hi, if it still needed, here is a link to the .sldprt file: https://grabcad.com/library/134n3p-circuit-board-1

This is missing a file right?

How does the IC portion stay connected to the battery?

Quote from the Creator:

"Hi, for the different parts of the head, I glue them together. And the battery part is just screwed

I used the file power_bank_b_2.stl as a base for the size of the hole in a power bank shell I created: https://www.thingiverse.com/thing:2620857 The original file does not show up in my project except for a hole approximately the same size as it.

Having an issue with the o_2 file...S3D slices it and it takes the wire groove and makes it cut all the way through. If I rotate the part, then it slices correctly, but that would be a lot of supports. Any suggestions on how to fix this?

How to connect the head,
With glue?

Do you have a link for eBay for the component please?

how long is the charge? will it charge your phone all the way?

This would depend entirely on the capacity of the 18650 cell you put in the power bank, and of your phone's battery.

how is this assembled and what parts do i need?
