I've searched for this, but haven't found an explanation, and thought someone here might know.
There appears to be a difference in the dedicated (AC) charger requirements for Ipods versus other USB devices (other brands of players, phones, or what have you). Moreover, there appears to be a difference between generations of Ipods, such that some generic chargers will work with older Ipods, but not the latest generation, and vice versa.
Since I know it's true for my Sansa MP3 player, I'm gonna assume that other similar devices that charge through a normal USB port will also charge with a dedicated charger that provides 5VDC at a few hundred milliamps, and such a charger need not be "intelligent" at all. Do Ipods require something different? If so, what? And how does that vary from one generation to the next?
Ideally, there would be Apple documentation providing this info, but I haven't found it. If someone has a useful link on this, it would be most helpful.
Thanks
Ditto,I'd like to see it too.
With my 2nd gen Nano,it won't charge no matter what I do. There's a 'trick' to getting some of the others to work from a 'non-smart' charger that involves a couple resistors on the data lines,to either pull them high,or low. This didn't work on my iPod,I guess it needs an actual USB host controller to negotiate with? I dunno.
