was thinking, what company. then I stayed in this model. ordered and received the next day. I ordered extra white, since my Samsung is also white. packaging and processing by the device looks very good. first fully charged .... at 19.40 clock has my galaxy s5 had 28% battery ... by 21 clock wars full ... I find super ... maybe there is quicker or so. but I am very happy at the moment. but time will tell how reliable the thing is ;-) but at the moment ... buy recommendation ,,
