This review is from: Anker 2nd Gen Astro3 12800mAh 3-Port (4A Output) Portable Charger External Battery Power Bank with PowerIQ Technology for iPhone, iPad, Samsung, Nexus and More (White) (Electronics)
I tried 4 times after fully charged this external battery. Very Disappointed. The real capacity is less about 8000 mHA. Don't expected too much.
Their customer service is very good. I satisfied their effort to this issue.
