Is complemented my review by the accompanying video.
The somewhat clunky charger comes in a small box and is made in China. An unpleasant odor I could not identify. The build quality is good in principle, only the plug is not really straight, but still fits easily into the socket. Due to the weight after the unit is not really stable in wall sockets with horizontal mount (standard), but it has quite a lot of game. Whether that will go in the long term at the expense of contacts remains to be seen. If power strips or wall outlets with vertical recording, the problem does not occur. Good news: Due to its slim design takes the station in a power strips only one place.
The Charger has a built-in surge protection and 4 USB ports (2 x 2A, 2 x 1A) for devices with 5V input voltage.
The annexed guide comes in English and German, the translation is okay. Lots of exciting not we learn here, for example, lay it remains a mystery why the device on two different connection options available.
If you put the charger into the wall outlet, a blue LED indicates the operational readiness. I have successfully tested several hardware (Samsung Galaxy S3, Samsung Galaxy S4 mini, iPad Mini, PS3 controller, PS3 Wireless Headset, various Canon batteries, TomTom sat nav). According to my personal feeling charging succeeds at the same time as the respective original power supply. The USB connectors fit perfectly into the appropriate ports.
Conclusion: Prima adapter with a high value, for example, even when traveling. Toll: increased safety through integrated overvoltage protection. 1 star deduction is available for the wobbly seat to electrical outlets with horizontal contacts - this could go at the expense of durability.
