Your MC300 will provide different information to you using the LED.
A solid white LED indicates that the MC300 is connected to a power source.
A breathing white LED indicates that a device is actively charging.
A red LED indicates that a foreign object is detected on the charge pad.
A cycling white and red light indicates that you a connected to a power source that is not providing a sufficient amount of power to the MC300. We recommend using a 30W charging source for best results.
