affordable alternative to anchor and Co.

Optical: Up to the color scheme very easy ählich to those of ACC and anchor and 5 euros cheaper.
Function / performance, I would rate even without direct comparison to the aforementioned brands as as well.

Ex .: 5 hours with an attached outdoor mobile (display permanently on max brightness, GPS and Internet connection) then the battery charge level between 50 and 75%

Small flaws:
The port for charging the Power Bank itself is working somewhat inaccurate, but not a big issue.
The glossy surface was slightly scratched on arrival (for me but no reason to degrade the rating because the part for outdoor activities such as geocaching, camping, hiking or Ingres's play is intended and there anyway at some point would collect traces)

Accessories: Short USB cable + adapter for iPhone (wide), Nokia, microUSB (Sony HTC Samsung), miniUSB, as in the picture
-> So no adapter 6 only 4, but the important thing is.
- Of course you can also simply use its standard USB charging cable for each device
To charge the Power Bank we a power plug with USB output required, which is not included, but the power cord from your phone does also ...

Delivery: be patient, will be shipped from the Netherlands, so min 5-7 business days
Packaging: Plastic package with many Asian characters, well the content counts

Conclusion:
All in all a very good alternative to the more expensive competitor
Loading reliable and does the job even when battery-sapping tours to get the phone alive
