I am missing some electronic components here. I used a multimeter to measure the output and it was only 4.1V. It is estimated to be related to the lack of electronic components. The following circuit is TP5400, a lithium battery charging and discharging integrated circuit.

I think the hardest part is getting the chip talking to the charger. Great to see that you have achieved that by just using a wire. However, that could also be a problem, because Qi regulates power continuously. My sample outputs 5V really stable.

I changed multiple coils.4.1V is still displayed. I don't know where the problem is.

I use bq51050B according to the schematic diagram. 4.1V is displayed. Replace bq51013b to 4.9V. .
