I bought a 1 amp max from Goolge (through HandHeldItems) for $7.84 which includes shipping. Can't beat that....and it works!
Got a tip for us?

For those of you who doesn't want to open your charger and get electrucuted like leodavinci0
, I adapted a USB male-USB female extension lead like this one.I have:
- Bougth two resistors with values in the ratio about 1.25 (1st resistor 130Kohm and 2nd resistor 100Kohm). I spent 20 Cents.
- Cut the extension lead in the middle.
- Connected the red cables on both halves of the extension lead together with one end of the biggest resistor (eg. 130K). Isolated the connection with insulating tape.
- Connected the black cables on both halves together with one end of the smallest resistor (eg.100K). Isolated the connection with insulating tape.
- Connected the white and green cables of the "FEMALE" half of the extension lead both together with the other ends of both resistors. Isolated the connection with insulating tape.
- Leaved the white and green cables of the half of the "MALE" extension lead unconnected and isolated (also from each other!).
- Connected the shielding conductors of both halves. This is the cable net covering the colored cables.
- Packed the whole connections with the tape.
That's all! I even didn't solded them!
I can use this cable to connect my Ipod cable to any of the chargers.
I'm going to do this in order to test if it charges with my computer at work, which only has USB1.1 and where I cannot install any drivers.
EDIT: it works even with USB1.1!
Actually, I wanted to check it with two identical resistors, in order to do it even easier. But if you say that it didn't worked with two 10K, it won't work with others.
Important seems to be that the bigger resistor is about 1.2 to 1.5 of the smaller one and at least 10KOhm (to minimize the power consumption).
I'm going to try with 100 and 130KOhm and the cable
Found a solution for my problem at least. I am using the backlight switch program to switch from high brightness to low brightness. I noticed when i had my settings low it was charging and I just had it on the high setting after using it outside and forgot it was on. So i figured hmm i will change it to the low settings, and it works...
Other people try this out,see if it works for you. Im guessing it wasnt getting enough power to power it alone or something

Just did what Agargar suggested and it seems to work great! (Took about 15-30 minutes and we soldered it!)
Thanks all!
Thanks all!
My laptop is old and only has USB 1.1 and my iPod Touch charges fine with it. Transfers are a little slow but I can deal with it.
Just the other day I was at my brothers place and noticed a Griffin PowerBrick plugged in with no iPod attached. I asked if I could check if my iPod Touch worked with it and as soon as I plugged it in it was detected and showed the charge symbol in the battery icon.
I use to have the same adapter for my old Nano but I lost it when I moved. I tried theirs just to make sure it worked with the Touch before I purchased another one.

Hmm...mine still isn't working! It was before I tried watching a movie at night and then it wouldn't charge.
Ugg...maybe I'll just get an Apple charger....

It was...or at least I thought. I used it a bit and drained the battery down to about 10%. I then plugged it in and it refused to charge!
I'm going to try again with lower resistors that will allow more current through.

You don't want to do that. Allowing more current through will simply heat the resistors up, redirect current from charging your iPod, and not solve your problem. Keep the resistors in the Kohms. Based on what I've read of your problem, it seems you may have a bad connection somewhere.
Btw...
My car power inverter, with built in USB charger, and my solar panel now both charge my iPhone as well using this method of creating a ~2.2 voltage drop on the data lines.

Don´t use resistors lower than 10Kh.
But, as leodavinci0 says, I don't think that´s the solution to your problem.
It could make it even worse. In the case that your charger is not providing any current, your Ipod may discharge through the resistors. The faster, the lower they are...
Did you adapted the charger or do you use the cable?
If you adapted the charger, you should be sure, that the data pins were "floating" before you put the resistors.
The cable solution is the best since leaving the data cables on the charger side (the male USB side) unconnected and isolated, you won't make any "short circuit" in the data lines on the charger side.
have you measured the voltages in the pins?
hi
i have an ipod touch 2g 8gb and i have tried whit 47k and 33k resistors (2,1 volt at the d+ and d- ) but do not work...
is the ipod touch 2g more "intelligent" than 1g and require a exchange of bytes or the 2,1 volt is an incorrect voltage?
thanks and sorry for my english

I'm not exactly sure what resistors I used...I got it to kinda work, but I eventually just got an Apple power brick (usb) in the Marketplace. I would look around on Ebay for one, it's easier!

That's a pity! Both my Ipod touch 1G and my Ipod nano 4G do charge
Have you checked that you've connected the 47K to 5V and the 33K to GND? (Otherwise you'd have 2.9V)
Perhaps is 2.06V too low...
You could try with 130K and 100K, what gives you 2.2V
I've also found this here:
http://pinouts.ru/Devices/ipod_pinout.shtml
(See pin 27)
You could try with different voltages on D+ and D-.
That is: leave the D+ as it is (33K to GND and 47K to 5V) but isolated from the D-, which you connect with another 47K to GND and another 33K to 5V. You must invest another 40 cents
But I don't know if it works... If you try it, please give us feed back.
@Coledog: As the new Ipods were released there were not so many "no name" chargers that worked, but now I think there are. The alternative of buying one is now easier, but not so fun! and the cable also works with a USB 1.1...
saludos
PS: I'm also sorry for my english
so quick question, not that im trying to steal the thread. i just saw as pointless starting a new one.
anywayz your ipod wont charge with a griffin wall adapter.
Do you think if i purchase
this adapter
http://cgi.ebay.com/ws/eBayISAPI.dl...7295&_trksid=p3907.m32&_trkparms=tab=Watching
or this one
http://cgi.ebay.com/ws/eBayISAPI.dl...1097&_trksid=p3907.m32&_trkparms=tab=Watching
Would it work with my ipod touch? i would rather get the belkin knowing its a brand name wall charger but would the other No Brand Wall Charger work As well as the Belkin?
As far as i know, as long as it has that IC Chip which makes it so it doesn't overcharge it should be fine, Correct?
Thanks!

i was thinking the belkin as well. but i probably could find an apple. the only thing i hate about it, its that they can be a lot more pricey for something of the same quality as a belkin or a NO BRand wall charge, just because it has the apple logo their gonna charge me 10 dollars extra =/ lol.
but what do you think about the no Brand wall charger?
but what do you think about the no Brand wall charger?
The no name I'm not sure about...you won't be able resell if it doesn't work most likely.
It's not a question of being a known brand or not. It's just a question of being compatible with the ipod. Apple assures you that you can charge either with a computer with USB2.1 or with his charger. In order to distinguish HIS charger from other ones, the ipod checks the voltage in the data pins, which usually are not used by the chargers. There are very cheap "non-apple" USB chargers that know that and put the proper voltage on the pins and they work fine! And expensive "non-apple" USB chargers that don't!!! (As long as they do not say that they are compatible with the ipod touch, that's OK).
Both ones you link claim to be compatible. I would go for the cheapest one.
yea thanks i think im gonna go with the cheapest one, like u said they do say their compatible with the ipod touch. so it should work.
Thanks!
I have had a griffin wall charger for a long time now and it has always worked great o my iPod touch. I noticed more recently however that sometimes I have to plug and unplug to get the charging status. I have dropped it a few times and possibly because of that the wiring may be slightly loose. I have found, though rudimentary, (like clamping down an iBook g4 to a table with a failed logic board to get it to run) that if you hit once before plugging it in it does have a greater chance of working.
