You can, just use usb to 30 pin cable cut the usb plug and solder it to the battery pack.

What do you mean with the 30pin?!?

[Aiyo]

Its the part that plugs into iphones and ipods.

I have the geekpod 100. It works well, but cost more. 6000mah lion battery. The only problem I found is if I leave the adapter plugged into the battery without connecting ipod/iphone the battery drains. Other than that, no problems.

Please help! I stumbled onto this thread whilst searching the net for a problem with my charger! I am using 4 AAs that are pretty much fresh. When everything is set up (im using 560 or 530k resistors i don't remember) charging initializes, but it doesn't actually charge...I checked the voltage and when the ipod isn't plugged in my battery pack gives 5.1v, when it should give 6 and when the ipod is plugged in, 4.1v. It really doesn't make sense. If i use a 5v regulator i get exactly the same results...I don't get it, my resistors are in parallel (obviously) i have no diode, why is this happening?

Cheers!

If you need any further help just ask. You can use any case that holds 4 AA batteries. You need 2 resistors each 470 kOhm and any female USB cable. This way you can charge anything that needs 5 Volt. The resistors you need to trick the iphone to accept the charge. Here is also a site that shows the pinout for USB.

But be carefull guys, don't damage your phone.

Thanks for the iphone charger tip.
I tried it but did not have 470K resistors so used lower value (47K)
It works great on my nano, but not on my iphone;
is the resistor value of 470K critical?

Yes it is. With 47K you're letting ten times as much current into the serial port of the phone, you can damage the phone by doing so! Please if you are not sure what you are doing, do not try stuff out. Read the whole thread, I mentioned it several times. I do not want anybody damaging their phone. You need 470k or close to it.

For $5 after MIR I got this portable charger and it works great:

Go with option two...

My bro bought it and it is lightweight, affordable, and works like a charm.

Charger I made

,--[___+_]-------,---,-----|POWER USB
'--[_+___]-,     |   |     |
,--[___+_]-'     R1  R1----|DATA USB
'--[_+___]---,    '--------|DATA USB
             '-------------|NEGATIVE POWER USB

I used 470K ohm resistors for R1 and it didnt work. THe ipod kept changing from charging to Plugged rapidly and it didnt do much else. I also tried 100K ohm for R1 and it also did the same thing. Someone said the pins can only handle 3 volts (data) but when I tested it with a voltmeter (not much of a load) it showed NO voltage at all. Hmmmmm...

I will suggest for the third one as I am using it from a few days. It lasts a good time. But it takes a little bit long time to become charged I think. Looking for something new.
