Very good battery with good connectivity

I've bought the battery, since I use a tablet to take notes in the university and as a Unitag be kann.Der battery is very long to be very well made and looks very chic, and for me the design rather less decisive has given purchase. The 15000 mAh are been important to me, so that I can use several times DCEN battery and it does not need to load every day. Connections are also off the right people. Currently I use two of them regularly. The 5V 1A output for my phone (HTC One) and the 5V 2A output for my tablet (Samsung Galaxy Note 10.1). The two function properly, what leads me to believe that the other two are also top but I have not found anything to try them. Surely you can be mobile to the 5V 0.5A output connect but that will probably take a long time, similar to a normal USB port, which also provides the maximum 0.5A.
So if a large capacity battery examined at a reasonable price, which can strike here gladly.
