I found the blue version quite appealing. The blue comes just over as on the product photo. Very nice (similar to the color of the apple brand ;-). The feel of the case is quite easy "velvety", fits comfortably in your hand.
The technical data: There is a Li-polymer battery with 3000 mAh. So standard. The weight (weighed again!) Is about 80 grams. The battery also fits nicely into a larger cell phone pocket and is always at hand in an emergency.
As an accessory, the multi-lingual instructions are in (the way in a good German translation, one has not always) and a short USB ribbon cable.
Apparently missing the battery test button to display the loading capacity. The trick: tapping your finger on the status LEDs - already the battery level is revealed. A funny gimmick.
The battery also has a sort of silver-colored eyelet which is shaped like a bottle opener (1,5 * 0,5 cm). You should probably similar for a fastening tape serve, because that evening beer you can probably only once open it. ;-)
The packaging looks quality (see my uploaded photos), the quality is beyond any doubt (I ground myself now just once, to judge, since I already have dozens of items of this publisher :-).
The Power Bank is a nice gift idea. Top processing and the price, well, something we do not need to discuss.
Small drawback: The USB cable is for me personally a bit too short. To charge a smartphone sufficient, but in a tablet would be a longer beautiful.
