For the price compared to other similar product it's still okay. As against this is far from the description ... this battery is supposed to charge my smartphone 3 and a half ... I can recharge struggled to 2 times (not a block) my galaxy note 3, if we make the calculations 3200mAh or 6400mAh x 2 = 5600 are past ?! in addition it puts a time to recharge to flee (1 day or 2) ... It smells China has full ... Opt for a better left to pay the price unless your needs are casual.
