Backup power source that runs on AA/AAA batteries?

Mona S asked:


I’m headed out on a very long flight in a few weeks (16 hours) and wanted to take my portable DVD player along. Unfortunately, its battery life is only 2.5 hours and my seats do not have ac ports on the plane. I know you can get back up power sources for ipods and cell phones that run off of 2 or 4 regular AA batteries. Is there any such thing that would allow me to plug in the DC power source into something that runs off of AA/AAA batteries? The other option would be to use the car adapter that came with the unit. How long would a set of batteries run?

I have an iPod battery backup that will let me listen on a long flight, but it takes AA batteries and I want to bring extra batteries in case they run out. Will the screeners let me bring them on board?

DAMN those terrorists!
