Press the mode button twice in rapid succession to set the output wattage, the light will flash in different colors 3 times to indicate the output wattage: flashing white is 16W, flashing green is 14W, flashing blue is 12W, flashing red is 10W.

 Note: If you use 0.65ohm coils, you cannot adjust the wattage because the coil’s resistance is less than 1.0ohm.
