I (12 V and 230 V) and as compared to other USB cables tested the cable to different USB-DC converters and the charging current reached on mobile read or recalculated. With the original USB cable of the mobile phone while charging significantly higher flows are achieved in numbers, this means about Original 750-1000 mA and the Wicked Chili microUSB cable can be achieved (with a lot of goodwill) 300-400 mA.
The cable is good perhaps for the data sync. but for fast charging, it is useless. Very unfortunate.
