The part can be set up relatively easily. From the factory settings, the device works unencrypted. But can encrypt any problems. Description is however very poor and can only be read with a magnifying glass, no German description. As powerbank for an iPhone, is more of a joke, probably more for a simple mp3 player. In 1800 mAh kan maximum of 900 mAh are fully charged. Battery life comes with a tablet out. Speed is good. Range, well, but I put that thing no 20 meters away from me. An absolute must have, who has a surf stick already, but this does not bring to run on the tablet.
