You clearly do not understand the vw device that remembers the power setting and adjusts to the device resistance without user input. BTW - how can consistent 2 Ω coils perform differently at different voltages? Different wick material perhaps but beyond that there is Ohm's Law. Argue with that if you wish.
Didn't I mention different wick materials? Are you not able to comprehend what you're reading?
I'm not knocking the overly vaunted Provari. What I'm saying is that without adjustment to the market it will be left behind and become a well constructed and warrantied piece of history. So argue with Ohm's Law as well as consumer marketing.
Oh yeah - Ohm's Law has nothing to do with how vapor is produced? Are you kidding!? I don't need to argue with you. You have already defeated yourself.
Not only is that attitude totally unwarranted, but your flat out wrong anyway.
Ohms law does nothing to describe or calculate the qualities of vapor. Ohms law allows you to calculate power usage of your device, that's it, nothing more.
You can have two different coils, both exactly 2ohm, and one coil will burn juice at 4 volts, and the other will produce almost no vapor at the same 4 volts. The wattage is exactly the same, so they have to be the same, right? Nope. Nothing could be farther than the truth. You don't know as much about vaping as you think you do, which isn't a bad thing, unless you cop an attitude with a fellow member who actually does.
Would you like to learn? If so keep reading.
The design of the coil is the single most important aspect that effects what kind of vape you will get. 4 volts is always 4 volts, 10 watts is always 10 watts. 3ohms is always 3ohms. The way those values interact with each other stays the same. That's Ohms law.
3ohms is a measurement of the electrical resistance of the coil, it is NOT a description of the design or performance of the coil. What effects resistance? Wire gauge and length. (And obviously the material of the wire) If you increase the length of the wire, you increase the resistance. If you increase the diameter of the wire, you decrease the resistance. The inverse is also true.
So if I set out to build a 3ohm coil, I have some options on how I'd like to go about that. I can use a short coil, which lowers resistance, but make the coil out of very thin wire, which will increase the resistance. Alternatively I can make a super long coil, but use thicker wire. In both cases the measured resistance of the coil will be exactly the same, 3ohms. But the characteristics and behavior of those coils are going to be completely different.
Ohms law, which controls the calculation inside a VW device, will look at my two coils, and in the eye's of Ohms law, the two coils will be identical. They are the same resistance, so the VW device will calculate the voltage based on your wattage setting, and it will provide the different coils with the same exact voltage.
But remember? One coil is long, with thick wire. The other is short, with thin wire. At the same voltage, the thin short coil will get way hotter than the longer, thicker coil, even though they are set at the exact same wattage setting, and are the exact same resistance. The longer, thicker coil has waaay more surface area than the short thin coil.
All that surface area is radiating heat away from the coil, and vaporizing juice in the process. If you have the same amount of power pumped into a coil, but you have way more surface area, that power is getting spread out over a larger area, meaning less heat.
So that shows you how the design of the coil has a HUGE impact on the vape. With identical wattage (which just means identical voltage and resistance) one coil will give you a hot vape, the other will give you a cool vape. This also impacts flavor as well.
Then add on top of that: the juice being used, the material the wick is made of, the size of the wick, whether the coil is surrounded by juice (like in a carto) or only touches a wick (like a clearo) the amount of airflow running through the device, the amount of heatsink material close to the coil (saturated carto filler, or a saturated SS Mesh wick) and the million and one other little variables that effect your vape and you (should) realize that wattage, in the real world, doesn't really mean much in regard to the quality of the vape.
So next time you attack someone here on ECF, at least have truth to back you up. There's nothing worse than an argumentative person who is clearly wrong on the subject they are arguing.
