How do I bypass charging port?

Open the unit and solder pin 1 to negative and pin 5 with positive to a cable or jack... supply it with 5v 1a or 6v 3a max

I can’t do the microsurgery to replace the actual connector but I found a spot to wire the ground and + wires from a USB cable. Apologies for my terrible soldering my eyesight is even worse then my Radio Shack soldering iron.. There are many places you can ground the connection. I just went for the easy target and soldered the green lead from my cable to the outside shield of the micro USB connector. You could probably also solder to the negative battery input. For the + terminal whuch for my cable is a pink wire I found a small through hole in the circuit board. I shoved a small wire into it and soldered my + lead. I then tested everything and used hot glue to make sure the wires didn’t move and compromise my terrible soldering job.

"that is AAAmazing . thanks

btw the world is having a pandemic these days."
