This is my third product anker in terms of removable charging and I have no complaints. The battery works perfectly and allows to hold hours and hours. Delivered in a small bag with the USB cable that goes well, this battery fits everywhere. Like all batteries consistently capacity is heavy, it must know. A light indicator shows the charging rate of the battery, rather convenient to see where we are! The small LED on the end proves too handy to illuminate the bottom of the bag when our battery was slipping;). In addition, the customer service is excellent and responsive, so a counselor brand! A buy eyes closed!
