content: I removed the diodes on this board, how can I pass the current directly to the opposite side to the input? the board is faulty, the diodes are not working and it is not available at the moment, what can I do? I can't find these diodes here. How can I pass the electric current to the socket in the socket?electricity has to pass through the input, how can I achieve this without a diode?

content: Short the diodes is bad idea - u can make more damage in the board when diode protected your circuit and fail first.

content: There is no electricity from the USB socket to the connection socket, this is the problem, let me explain it shorter and I can't find a diode properly.

content: May u send a better quality image with both sited (i have issue with reading it, i didnt even see a diode you have removed).

content: having to ask such questions I think it would really be better to just leave it as is. If you knew what you are doing you would not have to ask and just changing a circuitwithouth knowing exactly what you're doingwill not solve a single problem but kill more parts on your board.Sry, but nothing can replace just a bare minimum of knowledge about electronics.

content: If you read the question correctly, you will understand what I mean, actually, what I mean is very simple, taking the electric current from the USB socket to the connection socket

content: Those boards can often be found for peanuts in AliExpress.What about this short? Seems USB D+ and D- lines.Those diodes are just for ESD protection, not for power.There's a dedicated charger IC for that!

content: I tried it today and realized that it has nothing to do with IC, the current did not pass without a diode, this card is a design of a chinese twat
