Great battery backup

This little case is awesome if you find yourself needing some extra battery life for your phone. It is easy to put on your cellphone and extends the battery life triple fold. It charges rather fast and if it is installed on your phone it will charge the phone itself first and then the backup battery when you have it plugged in.. It also has an auto shutoff when your phone is fully charged. It has an easy to read power meter so you know exactly how much battery life you have. I recommend it for anyone needing that extra few minutes of battery. #RankBoosterReview #Sponsered #SinoPro
