I bought a I Charge Pro Fast Charge and had it fail due to over current (I thought it was protected against that)
The port that failed is the Green QC port. I have taken apart and fixed this but it will only charge at 5V the data pins traces are broken.
I need a photo of the Circuit board so I can see where these traces go as mine is too damaged
I have been asking alex if he could spare 5 minutes to do this for me but he can not.
I have attached pictures of how you remove the front cover with out damage and the area of the board I need a photo of. If any one else has bought one of these and could take a photo It would be greatly appreciated. See attached photos.
I’ll see if mine is the same when I’m in work tomorrow. Take note, the resistor in that pic (marked R050) and the rest of them on the board with the same markings are current sense resistors and are prone to failing. I’ve had to replace mine.
I got this working the Green QC port now Fast charging 5.0v @2.1 A but it is not changing to 9V as it used to.. it must not be negotiating correctly something is blown. any idea what chip /mosfet controls the voltage boost ??
