I've been looking quite a while for a decent external battery for my Samsung Galaxy S4. As I see more and more of 'm each day, I was wondering whether you guys have some advice on picking one.
At this point I think the Powerbank Samsung 12000mAh is one of the best options. Anyone here using it? Or other suggestions? I'm looking for one which can charge my S4 about 2 to 3 times.
