Packaging and delivery
**********************
The unit is supplied in a cardboard box decorated unobtrusively. In addition to the device itself has two USB charging cable of different lengths, two adapters (although these are superfluous), a soft case and a user manual are included.
Feel and build quality
************************
The charger itself is amazingly high-quality workmanship - which I would not expect for such a low price. Also, it seems sufficiently robust to one or the other a blow or fall without survive consequences. If there is something to criticize, then it is the supplied charging cable that does not leave the impression quality (ribbon cable). However, one can here easily own cable (USB to Micro-USB). The charging status can be retrieved by means of a button and read the basis of four blue LEDs.
Application
*********
The battery charger has a micro-USB (for charging the battery charger itself) and two standard USB outputs for charging up to two external devices simultaneously. So, first you load on the battery charger by connecting it via USB to a computer or USB power adapter. The charging takes a few hours and should be done overnight. The progress of the load is indicated via the LEDs.
After charging is completed, reportedly is a battery backup with 10,400 mAh available. This statement I doubt. Here providers exaggerate always enjoyed. I suppose that internally 2 pcs Li-Ion are built of type 18650. Given the favorable total price that will not be the highest quality. Over 4,000 mAh, it is not safe. But this reserve is enough to fully recharge cellphones and tablets at least partially can.
Conclusion
****
For relatively little money you get here is a well-made and easy to use solution to be able to battery-operated devices for a long time outside an electrical outlet.
