Dear Manou,
Many thanks for your message responding to my query. I do know about Kensington's cig-lighter adapter ($80 here in the US), and I do agree it's better than using an inverter plus adapter. But my question was really this: Why can't I simply put two 12-volt batteries in series, thus generating 24 volts, and let that be the power-supply to my iBook (and so to my GPSNavX navigation display)? That ought to be the simplest solution of all; but I'm afraid it's hard to find a coaxial plug that will fit my G3 iBook.
yours,
Peter Smith
