PA-10 or PA-12: that is the question. The PA-12 charger is 65 Watts, the PA -10 is 90 watts. If your Latitude or Inspiron laptop came with a PA-12 you can use a PA-10 as well to charge your notebook battery. If you are going to use the Dell PR01X port replicator you must have the PA-10 as the PA-12 will not power the dock.
