Yesterday I got the device in a einwandfreinen state and delivered on time. Overnight I have loaded properly on a 5V Laderät and had after about 3 hours 100% charge. This morning I, full of anticipation, my new Power Bank wrapped to offer my throughout the day constantly becoming empty batteries forehead. The disillusionment followed about 10 minutes after the first load test. This was simply canceled. The device turns off easy. Throughout the day I have made further attempts to find the cause of the spontaneous shutdown. Unfortunately, there was no discernible pattern. There was no completed charge cycle. During each test the Power Bank switched off. However, one must be able to rely on if you connect a device that is currently being loaded. You look not every 10 minutes on the charger if it is still on. Thus, I have chosen me to send the unit back.
It is a pity, because the Power Bank makes a good impression from the Verarbetung and accessories let nothing to be desired.
