Updated 52716i have to say for me this particular model of the anker external charger still rates 2 stars at best however after i wrote my previous review i wrote anker about my issue since the battery was still under their 18month warranty

The timing was terrible too since i assumed it was in working order and had a dead phone which the new battery i had fully charged the night before did not aid with
