Ok, I've spent an hour on this and I know it's the kind of thing someone will just know off hand.
I have a second hand Motorola HS820 Bluetooth headset. It has the propritary Motorola charger for headsets - not as big as the old motorola phone charger connection, but smaller -- 2 hooks and a few pins.
I have a mini usb car charger for my Blackberry. I would *LOVE* to be able to get an adapter that I can use to charge the headset without buying another car charger-cord. I just need a little adapter that can take USB power input, and plug into the Motorola headset.
This is more or less what I need:

Except (ideally) the input would be a mini-usb and the output would not be the old Motorola Startac style, but their older bluetooth headset style.
*phew* Hope that makes sense.
