Unfortunately, the internal resistance of the USB cable directly from cable is too high. With a 2A charger and a good cable I can to my OnePlus One battery with a maximum current of 1800 mA load (s. Photo 1). With the same charger and the 1.5-meter cable of cable directly to reach a maximum charging current of only about 600 mA (s. Photo 2). The charging time of my 3100-mAh battery would be so more than 5 hours! That is not up to date. For the high price, I expect a reasonable copper cross-section. I have 4 cable Direct pattern tested and all brought the same bad result. The cable anchor (in lengths of 30 cm, 90 cm and 180 cm), however, were all very good. Those looking for a cable which is not only suitable for data transmission, but also for fast charging, should not decide for the cable Directly.
