Have used the adapter with a matching USB cable for charging an iPad Air 2 and measured the charge current. It resulted in a current of 1.5A. With an original cable flow 2.4A, ie 60% more charge current and of course a much shorter charging time. A relatively high internal resistance of the internal conductor structures apparently prevents higher currents during charging. When iPhone 5S showed measuring almost 1A, which corresponds to the value of the original cable. The data synchronization, however, works with both devices properly. Therefore, as "minimal adapter 'recommended in the wallet quite.
