OK guys, I got the point, the guy asked me in my native language about the voltage of the ultrabook adapter, no big deal. I agree he should have done it in English, but since nobody's helping me anyway, what's the fuss?
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...
