I'm spending a great deal of time outdoors with my Samsung Series 9 ultrabook and I would like to purchase an external battery/power bank. However, I am puzzled as to compatibility. I have been advised to try the Anker Astro pro power bank (http

Anyone knows if it works? Or has tried some other external battery? I wouldn't try anything less than 15000/20000 mAh, or at least, preferably two extra charges.
