Hello. Have the powerbank purchased by Goodstyle and receive, and have to say the products has real expectations all more than fulfilled. The power bank is small, handy and does not weigh too much, that's very nice design and it's really recommended for this price! The shipping was very fast and good. Have the poeerbank tested directly and have realized it was worth it. Because to get for this low such a good powerbank is super! It loads without problems every phone from me, whether at home, in the car, at school, wherever. Thus you do not need to be afraid again that time the charge indicator is at 0. As I said, great product at a great price, only recommended career, still order me more products from Goodstyle at Amazon! Mfg John
