Introduction: Mini Portable Ipod Charger

Picture of 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

Picture of Tools

small flat head screwdriver (to take 9v battery apart)
soldering iron
hot glue gun
wire strippers

5v regulator (can be found in Meany eletronics, i got mine from a ps1)
usb socket
hot glue
electrical tape

Step 2: Take the Battery Apart

Picture of 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

Step 3: Make a New End

Picture of 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

Picture of 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

Picture of Pepare 9v Clip

solder 2 wires to the negative side of the clip and one wire to the positive

Step 6: Add the Regulator

Picture of 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

Picture of 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

Picture of 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
see picture below copied from

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

max1zzz (author)GorillaGuy6662011-12-17

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?

max1zzz (author)ishmal11032011-06-29

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)

Cleasonsook (author)2011-06-09

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)

Kelshdog (author)2010-12-04

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

UgniusR (author)Kelshdog2011-01-14

9V will smoke your device...

ishmal1103 (author)2010-12-11

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?

Kelshdog (author)ishmal11032010-12-23

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

CaseBoy (author)2010-07-14

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? 

0_Nvd_0 (author)Rahul B2010-07-29

Check the polarity.

dude300 (author)Rahul B2010-07-04

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.......

max1zzz (author)SicilianMafia2010-05-06

just tried that and it didn't work

SicilianMafia (author)max1zzz2010-05-06

I think you have to start off the process with a itouch that's not jailbroken. so in order to do it, you'd need to restore your itouch before you jailbreak it with Spirit. So I don't think you'd want to start fresh, but just in case you ever do want a tetherless jailbreak and are willing to restore your device to get it, you know where to look.

that would be the problem
