I wish I had tested this charging cable times, but it just was not possible. Twice I ordered this cable, it came twice ruckzuck - but both times it was also completely without function: no output voltage, not even the LED lights up. The behavior of the suppliers be commended, because I was in each case without returning immediately the purchase price refunded. So: If you want to try it, it's not a risk ... ;-)) Only if then nothing comes Functioning, then yes also has the no purpose.
