    130watt/hr, I cant find any external batteries over 130. The m17x's battery is 85 watt/hr so this external battery should more then double my run time I'm looking to extend my run time to 4.5 hours. Right now I only get about 2 hours if I go into stealth mode with wireless on. Size is not a factor I just want the biggest external laptop battery i can find.

    A truck battery with a car AC adapter beats these and costs less to boot ;-)
