Can you list the part number of the Motorola charger & the power output printed on the unit?
It's all posted on Amazon, but here it is for your easy enjoyment:

I can confirm that Amazon is shipping the P513 /89143N charger, as pictured.
Use a standard 2.5mm or 3.5mm nokia charger (or whatever noname brand) and the adapter cable that came with the N900. Cheapest solution that works for sure.
Last summer I used this one while driving a camper.
Very cheap, only €4.95 and it does a great job....
While driving, I was using Sygic MM10 and charging my N900.
Still using it now in my car, it's a great charger
