I have had problems actually running my laptop (which requires 70 watts) on AA aircraft. I can recharge the laptop with no problem though.
Here's a reply in the other topic, which I copy here just for purposes of getting things rolling:

The problem is the aircraft's power supply. AA's coach power is that the system is often overloaded and cannot supply all of the devices that are plugged in
Actually, I have had this problem in coach AND first on the 757, and in first (both the Flagship Suite and the "old" first) on the 777. And, on the 777, there were only 8 of us in the cabin and at most, 4 of us could have had a device plugged in (the other 4 people were sleeping).
