When your Qbit is charging, it will display a solid red light. When it is 100% charged, the red light will flash.
To check if your Qbit is turned on, press the button once quickly. It will flash a solid color (either red or green) a few times.
To turn your Qbit on, press and hold the button for 2+ seconds.
There is no way to turn the Qbit off once it is turned on except for the battery to run out.
