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

[umarbutt610]

this factor: variable watts-volts / higher resistance / lower amps, batt life is an obvious equation…
whether low resistance, high amp draw actually hurts high output batts, i don't know, but its like comparing a heavier chasis car to a sports car with high rpms.

another factor that comes from old school vaping logic: sub ohms, high amps will "obviously" burn juice/coil/wick = nasty …. wrong.
Proper wicking, and air, atomizer design makes for "better" vape.

If you follow safety guidelines, sub ohms vaping makes getting what most want out of a vape much more accessible and bountiful; flavor and vapor.

not knocking VV VW and high ohms… just my opinion (and many others)

Thank you that was very nice explanation.

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

Nothing beats Granny's elbow skin in a Cisco on a DNA 30! As long as the Kanthal contains no metal.

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

You're right. I blame PTSD. I miss my buddy.

I prefer sub-ohm (~.8ohm) because I like to take quick draws.. 1-2 seconds max.

micro coils take too long to heat up (for me)

 

[Rosco P. Coltrane]

Power is v^2/R, you can either reduce ohms or increase voltage to get the desired wattage.

that's my entire point...When you CAN jack up the wattage going sub does not seem to matter....when the only way to increase the wattage is through reducing the resistance, it matters a whole lot.

I am still waiting to hear what new coil builds are available that make sub ohm irrelevant.

all in all do what makes you happy. Just don't go around telling others who may not have the knowledge on the topic that somethings irrelevant because YOU have no use for it.

 

[Rosco P. Coltrane]

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.

sorry if i insulted you. I apologize.

So your point if i Understand it, is that going sub-ohm is no longer necessary.

why?

 

[alkaiser]

i have not found anything that matches my .3 ohm dual coils (50+ watts at 4.2 volts) on anything other than subohm builds, and that's how i like my vape (hot, tons of flavor, and tons of vapor)

most people are fine with vaping at 10 watts, some at 20. i like it at 40-50.

 

[tj99959]

Because there are coils that will do the same thing at LESS wattage. The idea isn't to just use more voltage to get the same wattage. The idea is to get the same vape with less.

We can now build room filling +/- 2 ohm coils that work just fine on a 3.7v mechanical mod or a regulated PV (and the battery charge lasts all day).

Try one like this

Align your top cap so that the air flows directly through the center of the diamond.

Because there are now regulated devices that can deliver 20-40W unlike before. People went to mech's partly because regulated devices couldnt provide the current for the wattages desired. And in order to get high wattage with unregulated mech's, you needed low ohms.

But, if you have a high-current regulated device like the DNA20/30 which can do up to 30W/6A, it begs the question of why you want to use sub-ohm coils at all. You have much higher output regulated devices than say a year ago. They can get the same wattage with a coil of 1-2 ohms. But according to you, those people must not understand ohms law...

 

[Rosco P. Coltrane]

Diamond coil is a good one...got a .8 one rocking right now in a Trident. 26g Kanthal. It does work very well. It can work well at many different resistances including sub.

tj- We agree. AS you keep saying IF your using a device that you CAN jack up the power low ohm is not needed. The same results can be achieved as when i lower my resistance because i can't raise the volts.

Do what makes you happy and gives you the perfect vape for you. Personally i like toying with subs ohms on my mechs.

 

[Ahoy]

You notice sub ohm with the newer vapers (sorry to stereotype/generalize) it's a fad. It started about a year or so ago and has just progressively gotten more popular. You do see veteran vapers going sub ohm, but I see far more new vapers doing it for usually the same purpose (bigger clouds). If it makes you happy and keeps you off of analogs then by all means, go for it. But by doing this you MUST LEARN ABOUT SAFETY. Safety is the key to success when doing any form of rebuild. If you aren't safe - you are stupid. Plain and simple.

As others have stated, i'm sure that we won't see sub-ohm being as popular in a year or so. It's ok...but you can usually find just as good of a flavor above 1 ohm. Taste is subjective though.

edit- didn't mean fad as a insult to anyone directly. Just re-read my post and I did not mean to come off as cocky or anything. Safety is the key to everything, you don't even need to slightly consider sub ohm to want to learn all battery safety you can possibly learn. Using any mechanical mod you will need to at least take 10 minutes out of your life and learn a bit about unprotected batteries. It's not that it will blow up in your face like a mini atomic bomb...but it's overall nice to know to possibly prevent any human error which may cause shorts and such.

I think this is key, and something a lot of the sub ohm crowd needs to understand - not everyone likes a hot vape. I don't. I've been playing with my IGO, and while I do appreciate the cloud production, it's too strong for me for all day use. For that, I like a cooler vape, around 2 ohms and 8 watts.

Some people like shots. Some like to add some soda, and savor it over time. Some like a lot of sugary syrup and a little umbrella. To each their own. That's why I get a little rankled when sub homers start throwing around terms like "sub par vape" and get abusive when anyone dares to not chuck the vapor.

they said the same thing about rock n roll….

i don't think its a "fad" …although i am not all evangelical about it, i'm pretty sure the opposite.

its been here and multiplied hugely in a couple years… what seems to tick off the "vets" that don't do it, is that newbs come in and they can't escape being exposed to sub ohms info… and because there is a substantial element of safety prerequisite to doing this correctly they get all up in arms thinking its going to harm vaping in general.

time will tell, but in my experience with the evolution of vaping (provari/evolv fanboy from startup for 3 years), mechanical and sub ohms is a milestone.

ok i already said this but its important to note that if you know about sub ohms vaping, proper wicking and air flow eliminate the hot harsh vape that occurs when you subject an atomizer that is not setup for it to higher watts.

and re; "abusive" … it doesn't surprise me that there is an element in the "cloud chaser" set that has turned this into a sport; younger, more brash. The rocks come with the farm.

I would be more upset about disregarding safety guidelines myself.

Oh, I agree. I started a thread last week about not recommending sub ohms and mechs to newbies asking where to gets started, for that very issue.

I don't see it as a fad, I see it as another option for more experienced vapers. Options are never a bad thing - but telling people it's the only option? Nope.

This is actually a misconception. There are many factors to the thermodynamics besides just the resistance. It's easy to make a 2 ohm coil to hot, and a 1 ohm coil to cold at the same voltage or wattage.

 

[WattWick]

I feel like I have typed this a thousand times now.

My ideal vape is at 0.8 ohms in a mesh wicked gennie. I like a cool (as in temperature) vape. Which I get. I don't chase clouds, yet I prefer the quick response time and short draws this setup allows for.

For me, this is not a fad. It's something I have been doing for nearly a year. Same ol' 0.8 ohm coils in gennies. I found my sweet spot, and stuck to it. Do I feel like switching to regulated mods at higher resistances? Why would I? I get exactly what I want without adding an inch or more of electronics, buttons and displays to my setups. I press a button, suck on a drip tip for a couple of seconds... and I'm happy. What more could I ask for?

Sorry for being a bit sensitive on this subject. Just a bit tired of reading the same old sub-ohm is a fad and something kids do to be cool... and the misconception that crossing the 1 ohm mark suddenly turns vapor scorching hot.

Looks interesting tj. What wire gauge are you using in it? Mechanical mod or what volts do you like it at?
