What Is Variable Wattage?

Variable Voltage or VW: The user chooses a watts level (expressed in vaping as heat), generally by a potentiometer or button for digital adjustment. the variable wattage module then reads the atomizer or cartomizer Ohms and automatically adjusts the volts and amps (hundreds, perhaps thousands, of times each second) to maintain the user chosen watts level (heat in vaping).

You can the use of variable wattage in devices such as the Darwin, Stallion, JBox and Zmax among many others.
