Ok, I've heard there's a power solution to those that travel a bit on long plane rides, aside from extra batteries, that allows for a long term of power. I'm not sure exactly what it's called, or where to find it, but it's something I need to pick up soon (flights to India and Japan coming soon). Anyone have any ideas what it might be and/or where to find it?

Note: I believe it's something that's long and thin that sits beneath the notebook and is a power source (no, it's not a docking station). :p
