Car Charging

That's interesting indeed... and confusing lol

The Griffin PowerJolt for iPad showed up as USB when I used the stock USB cable, but the same charger showed up as AC when I used the charging-only USB cable.

I replicated this with 3 other chargers from different brands as well.

So I guess it's a combination between the cable and the charger?

No, its just the fact that your cable has the data pins shorted together.

D- and D+ shorted together makes it a charge-only cable.

ANY charger will show up as AC with that cable.
I wager even plugging it into your USB port on your computer will show up as
AC.
