I thought the problem was the cable provides (very poor as bent from the first time I wanted to connect) So I try yesterday with a new cable and the charger is not working at all. I'm really disappointed because the product was not part of top prizes and I thought I had a quality product.
PS: I have taken time to put my review because I had a birth that took me so much time :)
