Can someone illuminate me? Is high-voltage, high-resistance vaping better than low-v, low-r?

[JustVapingBy]

I just received my first VV PV, and started playing with voltages. I'm currently down to just a couple of working cartos (both dual-coil, reading at 1.8 ohms). Looking at the voltage chart, I should be running them not much higher than the voltage my previous PV used (~3.6).

However, my want for a VV unit came from wanting more, more flavorful, warmer vapor than what I was getting with my 3.6v ecig and 1.8v cartos, so finding that I'm sort of at the upper limit voltswise already is a bit of a letdown. It seems that to really use the higher-voltage fun of this battery, I'll have to get higher-resistance vapor-makers.

Is there an advantage to running a 5v device with a high-resistance atty/carto, versus a lower-voltage device with a low-res atty/carto? It would seem on the face of it that if the watts work out the same, the experience should be the same.

Dual coil as it's stated, have 2 coils. When it's reading at 1.8ohms, there's actually 2x 3.6ohm coils in it.

You can push your voltage to 5 volts with no problem.

I'm no expert, but I believe the higher volts and higher resistance combo runs less amps at the same wattage, and so consumes your battery more slowly.

@Xanthon - Thanks for the info! I have now cranked my Twist up to a healthier v, and am loving the results.

@Lt. Col. Killjoy - Ah, ok. That sounds like a good reason. Thanks!

There are also coil characteristics which come into play. Some coils are bigger, smaller, higher gauge... ETC

I tend to like 3ohm cartos for my purposes (6.4 watts). But the coils are fairly big in surface area on the examples I checked.

Nope because a watt is a watt. Watts are the trick. The only advantage in high ohms is if it is a long coil but they usually use lower resistance wire for that. If your stuck with high resistance wire sure but a watt is still a watt. Ohms law.
I'm sure some are tired of seeing this but here is a chart that demonstrates it and an Xl spread sheet if you want to calc it yourself.

Well, in my case, I prefer more of a cooler vape. I find the lower resistance cartomizers to be harsh on my throat.

I use single coil cartos in my tanks because they are less harsh and are much kinder to battey life on my Provari. I use 3.o ohm high resistance. I use juices that tend to prefer a wide variance of voltage. My more fragile fruit flavors seem to taste best in the lower voltage range (3.4v to 3.7v), while my coffee flavors seem to taste best in the mid to upper voltage range (4.4v to 4.8v)

So variable voltage is not exclusively for higher voltage. It is to allow specific voltage settings for each flavor to find that "sweet spot".

If you want warmer vapor, then higher power (volts or watts, although regulated watts is better) using higher ohm or dual coil ends is the better option. More consistency plus low ohm ends don't hold up as well.

Actually in the real world you will find that at the same wattage high v/high r will produce more volume but less heat. Several little differences come into play, like how fast the coil heats when emersed in e-liquid, the surface aria of the coil, etc,etc.

Better is always in the eye of the beholder.

I can see that. I would suspect that if they get that extra resistance from wrapping more coils you may get better/more vapor if you have the feed system to support that added BTU's. That is another thing I had failed to consider.

I love this chart... helped me understand some things... Like why I shouldn't turn my VV up over 4v with a 1.5 ohm carto ...

If you take more resistance and apply more voltage you'll get more heat. Now it seems to me that it doesn't take a whole lot of heat to convert "juice" into vapor in the first place. I would think that the lower resistance attys would get you to that point faster than the higher resistance ones.

But while I'm "blowing smoke" so to speak I might as well add that in cooking, some things taste better if they are treated with lower heat for longer periods of time, versus just frying it up at maximum heat. How this relates to vaping in flavors... have no idea. Could be some connection. That would explain anecdotes about different juices tasting better at different voltages.

I think you have figured it out and not even known it.

I think people who prefer the low resistance coils with higher wattage are more interested in trying to duplicate the heat that analogs provided them. They seem more interested in the throat hit effect.

I think others prefer a more cooler vape, perhaps searching for the best flavor that a juice is capable of providing...that "sweet spot". Different flavors/juices, like the anology that yourself provided with cooking with lower heat for longer periods, provide a better "taste" at a different specific voltage.

I'm not emplying that one or the other is best or better than another. It is a subjective preference.

 

[vapdivrr]

for some reason when i used to vape regular attys and carts i would perfer higher resistances, but now that i am using genesis attys lower resistances produces a warmer, thicker vape. these resistances are like 0.08 to 1.0 ohms. with these ohms you would vape them at 3.2 to 3.5 volts

 

[JustVapingBy]

Thanks much for all the good insight, folks! Definitely helps me understand things.

If you're using off the shelf atomizers and regulated mods it is also worth considering the amp limitations of your particular device. On many of the less expensive VV devices you aren't going to be able to take a low resistance atomizer to a very high level of voltage, because you'll get cut off by the amp limitations of the device. So, supposing the coil in the atomizer has otherwise similar characteristics you may need to get a higher resistance atomizer to actually get the desired wattage.

Good point. If you want warm vapor, many of the VV PV's with low amp limit switches (2.5 amp) definitely limit your options. Having a VV PV with a 3.5 - 4.0+ amp limit switch provides the user more options instead of limitions on what atty/carto you can use.

I love being at 10+ watts.

6+volts for me.

Don't need 6v if the resistance is low enough.
The 1.3ohm atty that is on my SB hits at 10.5 watts at 3.7v.
