I don't think that's the case with VW. As a matter of fact, I just tried it. Read below for the explanation.
Seems that some of the newer folk don't remember the times.
All regulated mods vary the power according to Ohms law. One is based on varying the voltage, the other is based on varying the wattage. I still prefer the variable voltage, since you can change atomizers without worrying about the ohms of the coil compared to variable wattage... take this as an example for those others reading it.
Variable wattage set on 40 watts:
Derringer RBA at .4 ohms, it will set the voltage to 4 volts running through the coil... good vape
Switch to my Taifun, running at 1.2 ohms... It gives it 6.9 volts.. I end up with a burned cotton..
Varriable Voltage set at 4 volts
Derringer RBA at .4 ohms, will change the wattage to 40 watts. and do a 10 amp pull from the battery.
Switch to my Taifun, running 1.2 ohms... It will change the wattage to 13.33 and draw less power from the battery (3.33 amps). Less power drawn, still good vape.
That is why I prefer the voltage option, but none of the newer mods have voltage mode. Wattage mode attempts to create the same heat... but that may mean over pushing thinner wires hotter and burning the coils. Hoever, it is what it is, and I have to change the wattage depending on which coils I put in.
