it is a SAMSUNG product so no worries. Loading poses no bp and very practical. I have not measured because I put the night on my bedside table :) I took the version with all reconditioned in elements. In the box, a cable was already present but to connect it to the mains, use your personal samsung charger for your phone. I find that a bit stingy. The back shell is provided samsung IQ and replaces your original shell. Warning, the thickness of the hull is doubled. which means that if you bought a complete shell ... well, it's missed ... it will buy a bumper because no hull incorporates this increase in thickness!
