This cellphone strap doesn’t really look extra cute, but it can serve as a backup baterry once your cellphone’s run out of battery. You just have to charge it overnight, which can then let you have extra 12 hours of battery life. So when you charge your cellphone, do remember to charge this phone strap.
Once your phone is running low of battery, just connect this strap to your phone as shown in the picture to boost your talk time.
