- Personally I find this pretty battery combines a beautiful autonomy at a very convenient system. - The very flat rectangular or even the limit of "ultra-thin" is very convenient to slip the battery in a pocket, its overall design also appears to be solid. - The small button side "switch" is very discreet and functional. - Small "LEDs" on one of two surfaces of the battery are both practical and "originally" nice, convenient because they tell us in shares of the load current or the remaining battery power and "originally" pretty because they are lit and extinguished a light blue they completely disappear to the naked eye from the surface of the case, Original! - The "micro-usb" hidden is convenient and very clever. In summary used to a smartphone and even a tablet, this backup battery fulfills its role and is the envy due to its practicality and share its beautiful modern design.
