In fact, I am not satisfied with the product purchased. After a short time I realized that the supplied cable, which serve to charge the battery or the mobile phone, have a loose connection. The problem in that that the battery was mostly still can charge, but this is no more energy to the mobile phone. It is noteworthy that neither the short still seem the long cable to function properly, either the battery itself responding not to a power supply or the phone is not on, the power supply, but which, as already mentioned above, the latter is more often the case.
