"Accessory Not Supported'

[harutik_11]

I have an old ipod nano charger I used a few years back but when I plug it into my iPhone its "Not Supported."

I was wondering If there was any ways around it, or if its possible to "fix" it.

iPhones expect there to be voltage on the data lines (USB has 4 wires, power, ground, and 2 data) before they will recognize an "official" charger and begin charging. In addition if both of the data lines are 2v, it will charge at 500mA draw rate, but if one of the data lines is 2.8v, it will charge at 1A draw (quick charge).

Long story short, the iPhone can tell if you are using an "official" charger or not. The only way to make an old or unofficial charger work is to seriously hack into it to add voltage to the data lines, which by then is probably easier to just buy a dock rather than waste the effort
