Only a last resort - NOT FOR SAMSUNG TABLETS

If I caught no mon device and my copy is functioning normally not recommended the device, since it or battery status display of all devices brings the batteries at once.
Capacity and charge speed seem to agree with my Power Bank, the problems occur later on when loaded with the power bank devices.

Here is a list of my devices and their problems / after loading with the Power Bank:

Moto G 16GB (2013): After loading with the Power Bank immediately drop from 100 to 92-91% battery level, forced shutdown at approx 8-10% residual capacity (normal 1-0%), duration otherwise similar to store the power supply ,

Samsung Galaxy TabPro 8.4 (2014): Although Samsung invites the tab, the same behavior as the Moto G.

Samsung Galaxy Tab 2 7.0 (2012) (Age 30-pin connector on the Samsung Tab): Not charging the Power Bank.

In Moto G and TabPro the battery indicators return to normal when the device is loaded with a normal charger. The wrong battery levels occur only directly on to use the Power Bank.

I will use the Power Bank only as a last resort and look around for an alternative. I risk it reluctant, possibly damaging my equipment through use of this power bank.

Two stars because the flashlight properly and the battery works even in principle.
