Why isn't it my JBL Charge II powering on?

Just purchased this Bluetooth speaker and it's not powering on. I've charged it for the recommended time and when I press the power button, the light flashes on then goes off. Connecting it with my iPhone, to test its charging abilities, I have to hold down the button in order for a discharge to go to the phone. I may have a defective problem but I wanted to see if a solution as to how to fix this issue was here first.
