Looked like it used half the power in the charger but I will see. sometime batteries get better as they get older. Only thing is that I wish I would have Gorton the red color. ### ⭐ Horrible product! Do Not Buy! *by J***N on Reviewed in the United States on March 21, 2016* Horrible product! Do they buy! Looks nice but would not hold a charge. Would not charge iPhone 6 either. Weird hookup piece added to the order to try and make it work.
