question about the PSPs audio jack

[COREGAMER]

Will it be possible to draw any power from the audio jack of the psp using a trs cable?
If yes then please tell me the pinouts and how many volts does the  TRS cable give out

There is power on the SPIO port.  I'll see if I can find the pinout again.
