The product arrives in Germany but the packaging is in Chinese. Obviously not notice, just behind the drawing package. Supplied with a USB / micro USB serving only to charge the battery. My phone did not appreciate that I try to load it with or I try to file transfers via PC. A small red LED to say it load, a blue LED to tell that it's full and only 20% gain on my phone. So the battery is NOT 2600mAh but 400-500mAh. Last, the part between the ring for bunches of keys and the little piece of string VERY fragile. Broken in the first day.
