Variable volts. variable watts. Maybe I'm missing something, but to me it's the same thing.
Ohm's Law Calculator
Voltage mods just measure the voltage from the battery and then regulate the output of the mod to match the user selected voltage. This requires the user to pre-measure the resistance of the atomizer, plug in their desired amperage and then set the voltage on the mod accordingly. Since the resistance of atomizers change over time, it must be measured periodically by the user and then the user must adjust the voltage to get the desired wattage.
I hope that clarifies it for you.
OK, that makes sense. For me, I just turn the dial on my buzz pro until it tastes right. Same result. I really don't need to measure anything, I go by taste, not an LED readout.
This is how the Darwin works. You adjust the wattage, and it does the voltage setting for you to achieve the same wattage no matter what the resistance of the carto/atty is. Us provari guys have to think a bit about where to set the voltage when changing cartos....
I actually wished the ProVari had this feature before I bought it, when comparing it to the Darwin.
It's really a more practical measure, because it's a measure of heat at the coil(s) that is kept constant.
Do you mean a digital readout like the Darwin? That would be a nice added feature. I can calculate the wattage on my ProVari by reading the ato resistance and the voltage mentally. I=E/R and P=IxE. P=Watt, E=volt and I=amp or current. I am happy to just be able to tune in my ProVari for the best taste and TH. I do not concern myself too much about what watt am I at. I believe they make a small digital volt/amp gauge combination like the the digital voltmeter and use yhe P=ie formula. Some one will probably come up with one on ECF sooner or later. I am going to search for it myself.
To me, it doesn't matter. I tend to vape different juices at different voltages. The cartomizer resistances don't change that much that I've noticed. And I don't like the same voltage at all times during the day. When I first wake up and before going to bed, I like a more mild hit. With my coffee and after meals, I want a murderous hit. Other points during the day, I want it somewhere in between, depending on how much I've been vaping, how stressed I am, etc.
To me, having the ability to set a constant wattage would make no difference. Because I only use cartos and the resistance doesn't change much, if any, and I'm constantly dialing in/changing my voltage, setting it for wattage or voltage doesn't make a difference, it's taste, vapor, and TH that determines where I will set it.
