What I mainly charged with: Samsung Galaxy SIII 4G with a 7200 mAh battery Anker. I still recommend using a quality cable or origin for charging is as quick and safe as possible.
To nitpick, we can say that pay 11 euros more and from four to six ports is exaggerated, but it's the kind of product that you keep at least 5 years. As for me, it will not make him remove a star :)
