How does the induction holder work?
After connecting the induction holder to the power supply (5V/9V), the blue, green, and red lamps light up to indicate that they are ready. When the object is close to the induction holder from 2in (5cm) to 8in (20cm) in front, it automatically opens both arms, and when you insert the phone, the induction holder automatically locks the phone. The induction holder will recognize the phone and start charging and the lamp will light green.
If the phone doesn't support wireless charging, it will disable the charging function and will not heat it, but will continue to hold and signal it alternately flashing blue and red.
