Just to make sure I understand.... does the fact an adapter has the third grounding prong make a difference in the Wattage draw...? Or do the better adapters also do something about maximum power transmission....? Sorry, not an EE and mostly technically challenged, hence all the dumb questions.

The in seat power is only rated for 75 watts and then it shuts down. In actual practice some chargers (transformers) at start up actually temporarily draw more current (inrush current) and will trip the breaker for the outlet. If it's close, you can try plugging the brick in, quickly removing and plugging back in (like 1/2 second between cycles) and SOMETIMES this will work (tested with a Anker 65W brick).
I am comfortable to say a 100W brick won't work on an AA seat power.
Hope this helps!
