The iQ2 hairdryer is equipped with a TURBO function which multiplies the air flow for 30 seconds, bringing the motor to an incredible speed of 120,000 rpm.
To activate the function, you need to set the maximum speed and hold down the TURBO button for a few seconds. The turbo function comes into action when the LED turns green. Once the activation time is over, the LED will return to its color. If you want to activate again, repeat the procedure.
