Traveling to Tokyo on AA soon and want to use my laptop in-flight.

Discovered that I need a cigarette type inverter to connect the AC power adaptor PA-9 with my Dell C610.

Have researched many possibilities and think that the Black & Decker VEC1044BD will work. Specs found at http://www.blackanddecker.com/Produc...roductID=15545

Can an expert please tell me if my thinking is correct and this adaptor will work with an American Airlines power port?

Thanks in advance.
