Impressive mobile "socket"

I have the 15600mAh Power Bank kindly get provided by the manufacturer with intelligent device detection in white, to test this. The test has not been tampered. My opinion is unbiased and objective:

What does the Power Bank? I can mobile phones, tablets and other devices at any time on the road charging (instructions). And it works great too!

The first impression and the processing
From the package, I was a little disappointed, because these white and is not printed. So not very informative and boring. I was surprised by the relatively high weight of the Power Bank, yet it has a handy, slim shape and seems very high quality. For the jacket or trouser pocket I find these too big. The glossy white and silver shiny finishes are modern and appealing. Blue LEDs indicate the current state of charge of the power bank to read easily. A built-in flashlight, there are also, but is rather a nice gimmick.
The instructions are in German and English and easy to understand, but the device is intuitive and easy to handle. Toll are also tips on how to extend the battery life.
The Power Bank can be recharged via the included USB micro-USB cable. The device has two ports, 1 A (mobile) and 2.1 A (Tablets), with which two devices can be charged in parallel (z. B. mobile phones and tablets).

Performance and Capacity
The capacity is sufficient to HTC One about six times or my iPad Air about twice fully charge my. For the way I find that very impressive.
Full charging the Power Bank takes about ten hours with a 2 A power supply, about 16 hours with a 1 A power supply and about 34 hours by computer (according to the manufacturer). They seem a lot, but I can charge my devices without outlet or computer and am very mobile. According to the manufacturer the device survived 500 cycles and has a detection device that detects the device to be charged and supplied with the optimal power.

The Power Bank with impressive 15600mAh gets me 5 of 5 stars because it has excited me really. The endurance of the batteries, the optics and the processing are just great.
