This thing is very handy but schelcht described and poorly photographed. It is an original Samsung battery supplied and a thin transparent protective case for the battery, which is not shown. The real scoop on this "kit" is the agebildete white box. It is a charger that plugs into a USB micro connector (unfortunately a corresponding cable is not supplied). Instead of the phone so you can hang the white box including a second battery to its USB cable and charge the battery regardless of the mobile phone. Then the abgebildetet small LED lights above the white box red when the battery is charging and green when the battery is full. The charger is only slightly larger than the battery and it has a cover so that the battery can be transported so wonderfully.
