I have cable now for over a week in use. In two tests, I found the Iphone to full power (maximum brightness, location services, Bluetooth, WLAN, etc) and have been using Navigon navigated about 30 minutes. The cable has enough power to the iPhone to date to provide them with enough power and in addition to load (30 minutes about 20%). This performance can I find more than adequate. In a Skoda Octavia (car jack about the middle of the center console) it is sufficient to disc without tension on the Lightning connector. Furthermore came not once an error message about incompatible accessories or similar. The few euros more for this cable have definitely worth it!
