Charging the iPhone

[slrcflyer]

Does anyone know which strips on the usb 2.0 cord actually charge the phone? I am working on making an external battery powered off of AA batteries.

Wow, I applaud your enthusiasm, but it sounds like you're going to put way too much work into something that won't be worth the headaches.

Either way, good luck with that.

Why waste a bunch of batteries when numerous companies have done the dirty work for you?

I was going to do that with my cordless phone.

Hello,

I would be careful not to overload the batteries.

Here is something, I may get, when I get an iphone 2 and it supports business Apps, its a batterypack for the iphone. Says it uses the batery pack first then switches over to the iphone's battery. Don't know how well the company is though.

When you're done, and if it was succesfull, can you please post the procedure with pics? That would appreciated.

EDIT: Looks like something like that already exists and looks pretty nice and isn't expensive at all.

Thanks for the tips. I want to do this for many reasons. Namely, I don't want to be defeted by a computer. I plan to use C batteries for my device. I hope to be able to do more than charge an iPhone with it, though. I want it to be able to charge multiple devices at the same time without causing damage to anything.
