Hello! I’m about to start a diy power bank build from a kit I ordered from eBay it’s basically a box with a BMS,lithium battery case, 18650 welding brackets, and nickel strips. I was looking for spare parts to add to the build and ran across an old mycharge power bank the ones with the wall plug built in, two charging cables one usb cable and an apple lightning charger cable. My question is, is it possible to integrate the module and the AC wall plug into the power bank and if anyone can draw a schematic or know some place where I can find something similar to help me with putting the two together!
