Dunno for sure about the C series, but on our Latitude D600 and D610
laptops:

Was wondering if getting the 90watt PA-9 charger/supply
would effect :
- charging time for the 2x battery laptop ?

They'll work with either, charge times will be shorter with the bigger
charger.

IIRC, some of the giant Inspiron laptops wouldn't run at all with the
60W brick.
