Resistance questions

[ShellBox]

I tried asking this in the general forum, but no one answered me so I figured I'd ask the vets

I have an EGO-C Twist, and I liked to vape at about 4.2 volts.
When I bought my atomizers, I just picked 1.8-2.0 resistance because I have no clue what it even meant.
It seems to be working great, but I just wanted to know if I was doing it right...
Is that a good resistance for the volts I vape at?

And also, I've noticed that the pull is kind of...tight I guess? I'm not sure if that's the right word for it.
So if I get a higher resistance like, 2.8 or above, is the pull not as hard?

To the question - is 1.8-2.0 ohm ok for vaping the Twist at 4.2V - Yes. That should work. What you want to know is the total wattage which at 1.8 ohms and 4.2 Volts will be V X V / OHMs or 4.2 x 4.2 / 1.8 = 9.8 Watts. At 2 ohms that's 8.8 Watts.

Here's a chart that helps:

Above 10 Watts (miliages vary here) you are risking burning out the coil and straining the battery. Very few flavors require that level or above - still the vapor is huge and some are willing to trade that for buying a few more cartos, attys and batts. Your choice I have one PV where I vape over 10 Watts - espresso and that is one of the flavors that comes alive with more heat. Most flavor will wash out or even burn, much above 10 W.

"Pull" is a good word... "tight draw" also communicates. And actually the higher the resistance - like going from 1.8Ω (ohms) to 2.8Ω you will get less wattage and hence less heat - you are more likely to experience a harder pull on the 2.8 than the 1.8 ohm atty. You'll get more vapor with 1.8 and the draw should be easier. BUT ... that's just in terms of wattage. There are other factors that affect the draw - either the design or a plugging of the air channels in some form will affect it. Also a heavily gunked up coil can affect air flow since almost all air runs past the coil.... so soaking the atty in (I use) 151 proof clear vodka for 30 minutes can help the draw and efficiency of the coil.

There is a big variation in the air draw of atomizers that does not seem to affect cartos and clearos as much.

I buy my atties on the basis of air draw, vapor quality and taste. Everyone's idea of the best atty is different so you just have to buy a bunch and find out. For example I like a very airy, light, easy draw - others prefer the opposite: a tight draw. It's easy to make it tighter but impossible to make it 'airier'; and over time an atty tightens up and gets more restricted.

Some atties produce a ton of vapor when you get the voltage right - others not so much. Some have a good taste (i.e. nothing at all added to the vape) - others contribute something extra, even a plasticky taste that is impossible to get rid of.

Everyone's requirements are different, you just have to suck it and see
