Why is anyone interested in "sub-ohm" coils? At any desired power (watts) output, higher impedance will equal less current (amps) draw and longer bat

[WattWick]

The point a lot of people have missed is the OP asked *at any given wattage*.

The answer, I believe, lies in the surface area of the coil.

Not at all trying to lecture anyone! This isn't news to most of us. (read: your vape experience and knowledge is not being revolutionized ).

OP may be forgetting that we don't have a whole lot of options*. We are using batteries after all. Our batteries deliver a certain voltage. That's what we have to work with. While upping the voltage to reduce amperage seems a more sensible way to increase wattage, a battery only delivers so much voltage. This gives us two options (that I'm aware of). Either we up the number of batteries, or we draw higher amperage to power a boost circuit. We don't gain anything by upping the amperage for the sole purpose of... lowering the amperage?

*Edit: Oops. I may have forgotten that some like to vape within the wattage range given by a "higher resistance" at whatever voltage an unregulated battery delivers.

Sub ohm is mainly for mech mods where you can't adjust the voltage, so your only wattage (ie heat) control is in the coil resistance. Mech mods themselves provide a faster coil heat up time among other things.

Because the DNA 30 just came out and I can't afford it anyway.

Is this just another - I don't so it must not be right - Thread?

I find those who have never tried a properly tuned sub ohm setup are the most likely to ask why anyone does it.

Well, you just found one. Couldn't care less about chasing clouds or tinkering. But that's me. But hey, I'm one!

You are one of at least two. I also could care less about chasing clouds or tinkering with a rebuildable. Been there, done that. No longer interested.

I get to try various rebuildables at my local vape shop. Sales staff and customers' builds. I still prefer a great cartotank setup. YMMV.

Not to argue. Just a different perspective. I don't cloud chase or tinker with rebuildables. Yet, I use so-called rebuildables. Even tho I hardly ever rebuild or tinker with them. I chose gennies with mesh wicks to get away from tinkering and rebuilding. I'm the lazy RBA vaper. For me, they're not really RE-buildable. They're just buildable

It seems that sub-ohm equates to cloud chasing in some peoples minds. And the way they use the term, indicates they do not agree with cloud chasing. Open your minds folks. The cloud chasers are pushing this industry to ever greater heights. Even if you never plan to do as they do, you will no doubt benefit from their tinkering. Every new device engineered is looking to produce more vaper.

I use sub ohm in many devices...it produces a great vape for me. Not every system works well with sub-ohm. Some systems don't perform nearly as well without going sub. Experimentation is what is driving this to new heights....regardless if YOU found your perfect vape or not.

 

[Equality 7-2521]

I think he means the various incarnations of the microcoils.

What are these more modern coils that you speak of, and since they're not subohm, do they work on a mech? Are you speaking of that "diamond" coil type stuff?

 

[Equality 7-2521]

Not in the least. I don't equate sub ohms with cloud chasing at all, on the contrary.The idea that sub ohms will be a foot note is ridiculous. alot of coil choice for me has to do with the juice your vaping. some juices especially it seems the more complex juices really like sub ohms with heavy wire,it really lets all the notes of flavors come out.if you like the simpler flavors,or you can't really discern complexity of flavor then yeah blasting a a half gallon of jolly rogers down a your throat with micro coils and blowing huge clouds really works well. The other variable not being discussed is wicking material. whether cotton, ss cable,mesh,hemp, or ceramic.ceramic for instance is a huge heat sink... all respond differently to heat, and all wick and hold juice to varying degrees.Alot of the new devices, mainly gennys... especially recently are not looking to produce more vapor, but a more intense and eloquent flavor. I really appreciate all the different wire gauges and varying coil resistance, but when i want to enjoy a real delicous juice...I'm pulling out the 29,28 gauge and going south of the border....sub ohm.

I will agree that cloud chasing led to a whole new world of innovation. But, even if a person is chasing clouds, the sub ohm coil has become yesterdays news. We now know how to build 2 ohm coils that will blow any -0.5 ohm coil right out of the water.

 

[Rocketpunk]

I can understand that argument.

Not sure what coil you refer to. All sub ohm builds I use are micro coils. And every "new" coil design can be used sub-ohm. The device and wick seem to be more important in determining what resistance to use, and of course your own personal preference. But the idea that sub ohm is no longer useful because of some new magic coil build is just plain silly.

Part of this issue IMO stems from all the new VW devices. Give some people the power to blast a 2.4 ohm coil and they think "gee sub ohm is dumb". These folks have no buisness trying sub stuff....cause they obviously don't understand ohms law.

Please explain how ohms law is relevant. On a VW device you can run a 2ohm coil at 10W and (on some) run a 0.5ohm coil at 10W. I'm not saying it's the same vape, I'm just saying Ohms law doesn't really make a difference. Power is v^2/R, you can either reduce ohms or increase voltage to get the desired wattage. It's not like you can't get the same power dissipation from a 2ohm coil that you can't get out of a .5ohm. So I don't know what you mean when you say people "don't understand ohms law" if they don't see the need to subohm.

Now that's insulting!

There are many of us that feel that sub ohm vaping has become irrelevant that are quite well educated.
And, our point is quite simple ........... why do it when it is no longer necessary.
My "regulated" device has a 3.5 amp limiter, so I'm obviously not 'blasting' anything with it. And, I get the same great vape with it as I do with my mechanicals.

?????

Please elaborate.

Your turn.

I've yet to understand the point of these threads...but here I am, reading another one. Is it to start a fight? Or is the end game for all the sub ohmers to say "damn, the op's right! What're we doing???" I smoked non menthol...I didn't care if people smoked menthol, never even asked them why....just didn't care.
I like Kayfuns at 1.2 ohms on a ProVari. I like my Reomizer at .8 ohms on a Reo Grand. I like my cartos at 2 ohms in an IBTanked on a ProVari. I like my Trident V2 or Nimbus at anywhere from .5 to 1 ohm on my Nemesis. I like it ALL! Did that change the way anyone vapes? No. Did I expect it to? No. I'm glad people do different things...it gives me more ideas to try.

Asbestos is all wrong. You gotta try the Cisco! It's like sucking on granny elbows wrapped in socks. Best there is!

Reread the OP*.

He's not criticising anyone for using a sub-ohm coil, he's asking what the appeal is. Given Ohm's law alone, it should be the case that you can get the same result (in watts) using a higher resistance and voltage, cheaper (less amps).

WattWick has pointed out that you can't increase the voltage with 100% efficiency, so the assumption that it's cheaper doesn't hold (at least that's my understanding of what he's saying, but I know nothing about electricity, and might be misunderstanding).

The thread I linked to earlier explains why the same output in watts isn't going to be the same on different coils.

Nevertheless, from the basic equations it's a valid question.


* edit: well, OP is actually a series of question marks. Reread the thread title
