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?

Err... By connecting the source and destination with a wire?

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

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.

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 circuit withouth knowing exactly what you're doing will 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.

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

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!

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

They put 3 diodes, what was the need for this to pass the current to the opposite side, they could do it directly, the Chinese cuckolds made me try hard, but I connected a single point.

I have a feeling you will find out the purpose of those diodes the hard way.

Don't worry, I use diodes very often in my projects,
