While in Staples I spotted a Targus Power Inverter that is labelled as providing 90 watts. As my relatively new Compaq Laptop requires 90 watts and I have yet to see a power adaptor for my Compaq, I may get this power inverter. I would think it would work fine. Comes with airplane and car plugs - I presume on AA you use the the car plug. BTW, price was $59.98. Model no. is PAPWR005U.
