Completely satisfied! Use the Power Bank for iPhone and iPad. Loading reliably go. Capacity ranges at the iPhone 6 for 2 complete charge cycles, or for several partial charges. When iPad Air 2 for a complete charging cycle or several partial charges. This absolutely sufficient independence for charges on the go. And you can keep the battery very well between 20-30% and 70-80% in the ideal loading area. Size and weight are such that you always comfortable here can have the Power Bank. Have equal 2 bought, my wife uses it for their iPhone 6 Plus. We do not want to miss the Power Bank!
