I use the cable mainly go because my battery becomes flat relatively quickly and I'm relying on my iPhone. Despite the many things that I rumschleppe in your pocket and can damage the cable, it keeps the whole state and functioning properly.
Complete it in the car to a USB connector, then at the university on my laptop. The original cable I leave home, the LP secures the power supply in all other areas.
Bin yet satisfied and curious how long it keeps.
