A whole lot of power

Here I report on the Mobile Power Bank from the house Supremery with a battery capacity of no less than 15.000mAh. Meanwhile, I have quite a few Power Banks in different sizes, battery performance and from different manufacturers. The Supremery with 15.000mAh counts but the strongest of my little collection. The travel battery has two standard USB 2.0 ports (1x USB 5V 1A and 1x USB 5V 2.1A) for charging the device, a battery-level indicator, an SD card reader, and a small LED emergency flashlight. Charged is the Power Bank is a Micro USB port.
If the Power Bank is fully charged, it has enough reserves for 5 full loads of Samsung Galaxy S4. Only the 6th time the charging process interrupted. This result surprised me very much, since other comparable Power Banks made earlier limp.
The integrated emergency flashlight is of course not the brightest, but if times the power goes out, it is quite usable. The integrated card reader I have until now can not test and can about him, unfortunately, nothing to say.
All in all, my Power Bank of Supremery good transport and can safely recommend. In my eyes, the Power Bank has earned 5 out of 5 stars.
