I assume as long as the voltage is correct it should work.



The only matter is of the voltage differences,
Nokia N900 has 5V and 1320mA.
It can be fully charged if the volatage output of the adapter is equal to 5V, however if the charge output is less then it will take more time.
For example if with 1320mA it takes 2 hour, then with 500mA it will take (2*(1320/500))hrs=5.2hrs.

And as long as the concept of providing it more and more voltage for charging, it may be dangerous as it can burn out the circuits, can damage battery and device too if is more
