Good Power Bank =)

Unfortunately supplied no power supply is included. This is not promised, but I think you might expect it. But Nevertheless, you can also charge the battery simply load on the PC / laptop using the supplied USB MicroUSB cable, which can be used for loading and unloading. The device has two outputs (1A, 2A) to connect smartphone, tablet, etc, and an input for charging. In addition, there are LEDs that indicate the current charge level.

Processing / Optics:

The battery is high-quality and visually appealing. The included USB MicroUSB connection cable is also of superior quality. However, one must mention that the device is relatively large and heavy. It slips easily into your handbag / laptop bag to take, but in the trouser or jacket pocket, it does not fit.

Power:

Although a full charge takes quite a long time (according to the manufacturer: 10 h with Netzeil 2A and 34 h with computer). Here is of course to be noted that the device in comparison to the competition has a large capacity and is therefore not surprising that the full charging takes a long time. The discharge and recharge the device, however, is quick, and felt only a little slower than my power supply. My smartphone can be about 5-6 times recharge the device. It should be noted yet that the device naturally can not use all the energy for charging, but about 70-80% (rest is used for the conversion).

Conclusion:

You get here a battery with super power. My smartphone does it often not even endured an entire day without electricity and if you have then no ready outlet and its power supply case, my problem. With the Power Bank you can remedy this. My smartphone now survived for about a week with the help of the device! The capacity is abundant and should be sufficient for everyone.
However, one must then consider whether you need all the power of this device or perhaps a smaller, lighter version accesses (performance vs. portability).
