    Just returned from a trip and started getting the iPhone USB Over Current Notice. USB hubs shut off, cannot sync with any Mac in the house.
    Turned out the problem was an "iPhone/iPod Rapid Battery Wall/Travel Charger" from Abacus 24-7.
    Formerly ignorant, I now know that USB is a 5 volt standard.
    Here's the label on the charger, "AC Adapter. Input: AC 100-240V 50/60Hz. Output: DC9.0V 500mA. Made in China"

    Buyer Beware.

    Should this have broken the iPhone? That's a question. It seems to have. Is there a fix?

    Oddly enough, the iPhone now charges on the firewire dock of an older iPod. No Sync. Next step is to try it with the USB/Firewire cable.

    It probably blew a fuse in the phone to protect the battery and prevent it from exploding. The fact that it charges with Firewire kind of verifies this. So it "should" have done this rather than endanger people. It would have been possible to add a circuit to protect the circuit from overvoltage (or even use it to charge the phone), but that would have taken space and added cost. It is much easier to put a warning on the phone to only use it with products certified to work with the iPhone. There is no fix, and it probably is not covered by the warranty. But you could try.
