Introduction: Mini Portable Ipod Charger
I have a jailbroken ipod touch 3g, so if it runs out of power i have to re jailbreak it, i use my ipod a lot at school so i made this little charger
Step 1: Tools
tools:
small flat head screwdriver (to take 9v battery apart)
soldering iron
hot glue gun
wire strippers
stuff:
5v regulator (can be found in Meany eletronics, i got mine from a ps1)
usb socket
wire
solder
hot glue
electrical tape
cardboard
Step 2: Take the Battery Apart
remove the cells from the case, the only bits you realy need to keep is case and the battery clip ( i wont go into how to take a battery apart but this is a good gide https://www.instructables.com/id/Free-9V-connector/)
Step 3: Make a New End
take a piece of cardboard and cut it to fit tightly in the end of the battery, then make a hole just about the size of the usb socket, you may also want to take a black pen and color in in
Step 4: Prepare Usb Socket
connect the green/white (d+/d- [pins 2/3]) data lines this tricks newer ipods into thinking that it is a charger
Step 5: Pepare 9v Clip
solder 2 wires to the negative side of the clip and one wire to the positive
Step 6: Add the Regulator
wire up the regulator according to the instructions on the components data sheet, then plug it in and test that you get about 5v (I got 5.10v)
Step 7: Add the Usb Socket
wire up the usb socket red (pin 1) to out of the regulator and black (pin 4) to the spare ground, ounce you have done that plug a battery in to the clip and a ipod to the usb socket and see if it charges (if it catches fire, you did something wrong check wiring and try again)
Step 8: Put It All Togher
take the bit of cardboard you cut and glue the usb plug on, then push the clip down to the end of the battery case and glue it on from the outside, now finally push the end with usb socket into the end of the case and glue it in
Step 9: Finshed
now you can charge your ipod anywhere, this charger will work with 6.5v to about 35v, also with a 9v battery it will only charge four about 20 mins, but i have had success using a small 7.2 v rechargeable battery witch worked for over an hour

Should i attach a diode so when the battery dies it wont suck power from my ipod. If so where should i attach it.

7805 regulator is the best choice in making that charger. readily available
any electronic shop
but if your are planning to experiment something unique
you ca build a portable charger using transistor

R1 is 390 ohms for 6V or 1.5K for 9V battery
what about R2?

i think its fake you can charge take a screenshot and put as lock screen but pretty cool im still gonna try it but is ur iPod jailbroken

honestly it's not fake, my ipod is jailbroken, but that dosen't change anything

Where do the two wires soldered to the clip attach to?
Reply 12 years ago on Introduction
there are a total of 3 wires soldered to the clip, two negatives and one positive, one negative goes to the voltage regulator, the other to the usb socket, the positive goes to the voltage regulator (who's output goes to the usb socket)

just a thought
there are Sealed Lead acid battery's
small and light enough to be cared around and will
provide a longer changer time
with whats been assembled is easily transferable

I actually ran these on SLA batteries a few times, but unfortunately i don't have these anymore, needed parts for other projects, but they do run perfectly from SLA batteries (and last a dam long time)

Why does it have to run on 5v? Why not the full 9v available?

9V will smoke your device...

the nearest electronics store is pretty far away (aka - im lazy)
my towns dump is very close to me however and they have a whole bin filled with electronics
which electronics have 5v regulators in them?

i found a few in an old laptop that was broken. they were within a couple inches of the usb ports

can anyone help me...I am not using a super small regulator like in the instuctable, just a normal sized one. It would be a great help if some one could made a diagram or show a picture to where the wires are going.

Buy LM7805 (3 terminals). Terminal 1: +ve from the batteries. Terminal 2: -ve from the batteries. Terminal 3: +ve going to the iPod. Also connect -ve of the batteries to the GND of iPod. Check for USB connector connections and double check the polarity before charging the iPod.

I tried this and it doesn't charge my device (any of them cellphone or Ipod) I used a multi meter and I am getting 5 volts of current through the system. The one difference I did was that instead of using a usb socket I used a usb extension cable and cut it would this be the problem?

Check the polarity.

sometimes you need a resistor connected up with the data lines for some devices to charge, a better charger is the minty-boost having quite a high compatibility rate it does this using these 2 resistors in data lines,

I recently found a way to jailbreak my itouch 3g MC model, and it's tetherless too (meaning it can drain the battery and will still be jailbroken when turned back on. It's called Spirit. go chck it out.......
