charging adapter
 

i have this GPS, and it includes a power cord for both the GPS and a typical PDA.

Would anyone know if there is an adapter that i can get to go on the end of the PDA power cord, that would allow me to charge my n800 at the same time? i was not able to see anything about voltage and (milli)amperage of the charger, or even the polarity, so i cant say its even feasible.

i checked out radio shack, and didnt see much in that regard, but it was more a cursory look than anything.

just figured i would ask... what do people here do for mobile charging of multiple devices?
