Battery consistent with the description except one details the battery does not 5200mAh 6400mAh but rather a positive. The battery but 10 hours to recharge. It can recharge 4 to 6 times a cell with an average battery. I recommend this product which is not expensive. Delivery mark from March to October days I received it after 10 days. (There were Férier days) Suitable for this that make a lot of traveling and need an external battery to extend its battery phone. Article good value for money. Would recommend !!!
