What I want is to power the Karma off the car supply.
Ah, gotcha.
My thing with the Karma on a road trip is:
If I pack the AC adaptor in my suitcase, then I can charge it up while I'm sleeping between legs of the trip. The Karma's battery life is long enough (supposedly 12-15 hours) so that if the Karma's battery runs down on the drive, odds are I'm long past needing to stop for a rest anyway.
But I understand the desire to have a car-adapter for the Karma. Usually the way they do it with Cell Phone adapters is just to put a bunch of diodes in series until the voltage is dropped down to the level the phone needs. Cheap trick, but it works if I'm understanding it correctly. Anyone else got more information on how the diode thing works?
