You can get inverters made specifically for cars and planes, such as:
http://www.worldtraveler.com/product_p/trv12196.htm (not an endorsement, I do not own this device.) It has an empower connector (specifically for planes) and comes with an adapter for cigarette-lighter-jacks such as those found in cars. I think having something like this plus your device's regular power adapter, you should be pretty much covered.

A battery pack would still require a DC converter since mine works at 24 Volts. Moreover, I am talling about long haul flights--- flights lasting 12 or more hours.
I think you missed the point. I am talking about a dc battery versus a dc power supply that's drawing power from a another ac source. I am not talking about input/output voltage, current or power here.
My question goes beyond that. It's highlighted above.
Please do pay attention.
The range of input and put put voltages is rather limited.
Why would second configuration damage the unit?
DC battery===>inverter (dc converter)===>Power supply adapter===>device
AC generator==> DC Power Supply ===> inverter(dc converter)===>Power supply adapter===>device
