The output wattage of the Favostix device is adjustable from 1-30W.

Step 1: Quickly press the fire button 3 times to enter the wattage setting; the wattage value will flash to indicate that the power is being set.

Step 2: When the wattage value is flashing, press the fire button to adjust the wattage value, the value increases 1W per click (you can only increase its wattage). To reduce the wattage, you need to set the wattage to its maximum value (30 W) and then click the fire button again to set the value to 1 W.

Step 3: Keep on pressing the fire button until you reach the desired wattage value. Stop pressing the fire button to set your preferred wattage.
