I have recently received a Mophie 15W Wireless Charging Stand that was purchased from Verizon. The charging stand has a LED light on it. I have the Quick Start Guide that came with it and I downloaded a digital copy of the from Quick Start Guide zagg.com. Neither of these have any mention of the LED. When my phone is on the stand the LED has been off, on solid white, and blinking white. What do the various LED states mean? Thank you in advance for any help you can give me.
