How to make a portable usb charger using a 9 volt battery

this runs off of a 9 volt battery then gets converted into 5 volts it charges every thing Ive tried on except a iPod touch you can make it work on a iPod touch by simply adding a couple of resistors if needed help on how to make it work on iPod touch let me know. Things needed

do any of u guys know where i can get the female usb? and if so, how do i get it to be like the one in the video?

@RRooooooNNNN ahh fuck it i already got the heatshrink on it n shit too lazy to take it apart so i guess il just keep it plugged in and use it like that in emergencys

[RRooooooNNNN]

@pokemon2487 a23 battery have 2700mAhr, i would get two of those, only down side is the batteries are about $8 for 2 which you will need. smithba76 has one made in an alto ids small can as well

[RRooooooNNNN]

@pokemon2487 you need to use high mAhr batteries. the nexus take like 1900mAhr to charge.

[RRooooooNNNN]

@NewmanTutorials I built mine using 2 100K Ohm resistors,

@NewmanTutorials yeah i tried it and the 9v is all that will fit in he small can. I made a charger but had to use 2 9v battery to charge the iPhone, 1 9v was enough to charge iPod.
