Don't buy it. Worse battery case I ever gotten. It stopped working after two weeks of having it. The battery was charged but when I would turn it on to charge my iPhone it wouldn't charge. The case and battery seem cheaply made and of low quality nothing that you might think when you see the picture online. Yes, I am not an expert to say that the battery if made of low quality but from my experience and I feel I can judge the item for what it is.
Output:
I think is very important to know whether the item is of good quality or not
