I am really thinking of getting a PSP here in about 2 weeks and was wondering if you can get extra battery packs or something that fits the same purpose. I saw something by pelican that is a power brick that supposedly doubles the play time, but thats all I could in the little time I have looked. Also wondering what kind of bettery life you all are getting with it. I really want it for plane trips and what not to watch movies and play games on it of course . I am going on a trip in about month and the flight is 5+ hours and I would really like it to last at least somewhere that long.
