So is it too late to ask you anything more about the twist device? Or will i get another passive aggressive reply?
Compare the different voltages? Possibility of ruining a cart because of too low/high? Dont really know how that works. Do they come with a chart that would indicate voltage levels that will give what? I'd ask you to "sell" it based on a new vaper/hardly smoker but we might get into trouble again
No worries, I will still try to help you as best I can. That's why I come here. I'll work on an answer and post it when I can. There are charts out there, but you will not have to worry about burning out cartomizers/atomizers with a VV device with the output o say .... oh, I don't know .... a Joyetech eGo-C Twist, let's say.
Ohm's Law is what rules the vape. Volts times volts divided by resistance of the coil = watts. (I'm going to stick with a single coil for now, which is IMO the way to generally go anyway).
Watts basically = heat; how warm is the coil; how much does it warm and vaporize the juice. Maybe you'll like a range of 6 to 8 watts, depending on the juice oryour mood.
With a 3-ohm single coil, the Twist can be adjusted
between:
3.2v x 3.2v / 3 = 3.4 watts. Pretty "cool" - (the temperature kind).
4.8v x 4.8v / 3 = 7.6 watts. For me, just about enough to get the job done. Plus, longer battery life than with a lower resistance coil. *
With a 2-ohm coil:
3.2 x 3.2 / 2 = 5.12 watts
4.8 x 4.8 / 2 = 11.52 watts - more than enough for all but the most extreme vaper IMO.
With a fixed-voltage 3.7V device, you would get 4.56 watts with a 3-ohm coil, and 6.85 watts with a 2-ohm coil.
Period.
Of course, you can achieve other wattages with a fixed-voltage device, but only by changing attachments.

* On amp draw:
Another part of Ohm's law states that Amps = Watts divided by the amount of Voltage required to create those amps.
7 watts at 2.0 ohms requires 3.74v to produce. 7/3.74 = 1.8 amps.
7 watts at 3.0 ohms requires 4.58v to produce. 7/4.58 = 1.5 amps.
Since batteries are rated in milliamp hours (how many amperage units can it put out in an hour of usage), it makes sense that a lower amp draw per watt created will give better battery life. To me, it has always seemed counter-intuitive that higher resistance is easier on the battery, but there it is. A battery will last 1.8/1.5 = maybe 20% longer with the higher-resistance coil. Back in one of the "walls of text" is an explanation of why I favor single coils over dual coils.

And what you are calling "passive aggressive" I would call "getting tired of being attacked and feeling the desire to politely but firmly stand up for my rights".

And I feel bad for the OP too, which is why I just spent 45 minutes of my life explaining Ohm's Law to him ... at no charge. And many, many hours researching, collecting, editing, and posting information that I think is valuable.
If I am allowed to say so, this thread was doing fine until I was told how much to say, what not to say, and then how to say it. I am now considering leaving this site. Satisfied?
And also please note that I do not judge, label, or attack. Maybe that got lost in all the labelling, judging, and attacking being directed at me.
"I" speech vs. "you" speech. "This is what I think". "This is what I like". "This is what I don't like". "This is why". Please compare and contrast that to "you're a bully", "you need to stop expressing your opinion", "that's ridiculous", and the like. SURELY someone "gets" this.

Having done quite a bit in this thread to do just what the moderators rightly want us to do - help people - I hope I have earned the right to say what I just said about how I think things must be discussed in order for things to remain civil and on-topic. I do not believe that people should judge others, and I will continue to say that every time I am judged, or anyone is judged. Please just express yourself kindly and non-judgmentally, or this will go on and on and on and on. So will war, anger, hatred, and violence.

Almost forgot - if you haven't seen this, I really think you'll get a lot out of it:
