PowerBank Slim FPS220U

There is nothing worse than being on a 13 hour flight with some annoying git sitting next to you coughing up all over the place. Well I tell a lie - there is something worse which is all the above AND have no decent films to watch. To prepare myself for my next trip, I have been encoding a ton of anime to watch on my iPod. I use Cucusoft iPod Movie/Video Converter on a Windows machine (still have windows machines for QA and number crunching grunt work) and iSquint on a mac. These are the only two pieces of software that I have managed to find that actually keeps aspect ratio for widescreen movies.

But then I need power to be able to last through a long flight so I got myself this PowerBank Slim from Diatec. You can have a look at the new white version that they just brought out (annoying) and have a look at the use cases on that page.
Its very light and can probably fit up ones nostril (for people with large nostrils) without any discomfort - although it may get a bit greeny and sticky. I have not tried using it yet but apparently should last about 11 hours. Others who have this told me their PS2 lasts about 12 hours on this. Got it for 4,362 yen at Amazon.
