The cable itself works well. I wanted it but the Car - Dual USB adapter (2.1A / 2100mA) (redirect = true & ref_ = oh_aui_detailpage_o01_s00) use and that does not work. In this case, the maximum charging current 600mA, which means that the Galaxy S5 discharges when while driving the navigation function and possibly music requires. And it is definitely on the cable, because all the leads that I have tried, with the car - Dual USB Adapter work wonderfully (charging current 1,050 mA min.) In conjunction with the original power plug from Samsung but it works flawlessly (charging current 1.200 mA)
