Perfect, efficient, can quickly recharge and several times a iPhone 5S. 2 (very small) flaws: the size (rather bulky device, admittedly, difficult to hide in a pocket) and no electrical outlet, even if there has 2 micro USB cable for charging to connect a charger so that one should have. The presence of 2 sockets to charge 2 devices at the end, very useful. At that price, I believe there is no better, do not hesitate!
