on the device I invite (often simultaneously) my iPhone and iPad and both devices are loaded satisfactorily. When iPhone after about 1 hour, more than half is in charge capacity reached (from 30% to 85% load). When iPad I have not paid attention, because I usually connect to the charger overnight and the next morning have reached the 100% charge capacity. Together with the deleyCON cables (15cm) I have had a good experience and would recommend the unit with a clear conscience.
