Tc Vs Sub Ohm

So I've been building my own coils for a short period of time and I'm looking to better understand how my coils can affect my vaping experience, specifically varying ohms and wattage's.

I've been building mainly only one coil as I'm still trying to better understand the basics of coils and more importantly wicking. Ofc all I hear these days is how sub ohming is the best and with all the sub ohm devices I feel like I may be missing out on something if I'm not at .5 or below.

The coil I've been wrapping is a 28g .9 ohm single coil. If I were to go lower, how does this affect my vape on a regulated device? Unless I'm missing something, only the heat flux and quickness to heat would be affected right by lower resistance (given a set wattage)?  

When I first started vaping I always swore off building and dripping. I liked the ease of filling and vaping away. About 3 weeks ago I picked up my first rda. (Mutation x v4) it was ok and it leaked something awful so I set it aside. Well after watching mike vapes review of the troll I decided to pick it up. Just got it in today and threw a dual coil 24 gauge build in it. .came out to .34 ohms and vaping it at 60 watts on my m class. I haven't been able to put it down. I think I'm officially hooked on building and dripping. So glad I picked up this rda. Juice well is deep, holds lots of juice. For anyone who has been considering it, I'd recommend you pick it up. Here's a pic of my setup just for fun. I love my M class too! Vape on my friends!  

So I decided to try a 1,6 ohm coil on kayfun v4 clone Tobecco and I am using 28gauge Kanthal with a cotton
wick on a Rdna 30 and its vaping well at 15 watts I have a kanger subtank mini coming in the mail and here goes my question
So the kanger subtank states that with a .5 ohm coil i could vape up to 30 watts but the voltage comes in at like 3.8 volts
I was under the impression that the rdna 30 needs at least 4 volts to work which kinda brings me to my second question
What is the point of of sub ohms? cant i just build a 2.0 ohm coil or something like that to achieve the results as if i was subohming
I am very confused on this
thanks for the replys in advance
Oh yea is a 1.6 ohm coil at 15 watts a normal build or any recommendations for the kayfun v4 for watts and ohms thanks again  

Whats the difference between vaping on a subohm coil and a higher like 1.5 or 2 ohm coil at the same wattage? I understand why resistance of the coil matters on a mech, but whats the difference on a VW device?  

So I finally got around to putting a coil on the rba deck...my typical kayfun build, 28 ga @ 1.3-1.4 ohms. Everything looked good, coil tight....raised off the deck...screwed into the ohm meter....weirdness ensues....said 3.85 ohms...took it off, put it back on...said 4.6 ohms....looked to see if the coil screws were tight ...check. both tails tight under the screws...check. The coil deck screwed into the base...yep. No moisture in the base, nope. Put it on the ipv...said 7.7 ohms, then 4.2, then 3.90.............


Put the stock coils in the base, everything normal. Is there something I could be missing in the coil deck??? I got nothing else. No, I had not put the chimney on, so no short there. I may wrap another coil and see....I can only think that something is amiss in that little coil deck....or I am missing something in the build that is obvious. It's a really nice, tight looking coil too.  

I just burned through my first coil on my KangerTech Evod 2, and I started wondering if there was anyway to extend the life of a coil. Do big hits, or small hits make a considerable difference? Just wondering because ultimately it can either reduce or increase the overall cost of vaping.  

I've got a Nautilus with a 1.6ohm coil, and an iStick 50w. On the side of the coil it says 3.2v-5v, and I want to know if that's just a guideline or a limit for the coil.

I'm running it at 4.8 volts, but I get better flavor and vapor at 5.5 volts. There are no wicking issues or burnt taste at 5.5v, but I don't want to damage the battery or the coil. Any advise would be great thanks!  

Hello.
So I think i kind like a cooler vape been getting some heavy lung feeling lately been vaping a 1.2 ohm single coil 28 g kanthal
cotton wick on kayfun clone v4 Tobecco, i would like to try like maybe 1.8 or a 2.0 ohm coil or is the kayfun v4 really better for
lower ohm coils I keep reading where the kayfuns sweet spot is like 1.2 - 1.5 i did lower my wattage from 14 to 12 but i like to seem some clouds more of a flavor chaser than a cloud person though
so i am just wondering if anyone has tried a kayfun around 2.0 ohms and what the vape was like
thank you  

I've been using only twin-18650 mods for some time, and before the shipping ban came into effect, I bought a backup of my most-used mod (a Geekvape Aegis X), but since the 100W single 21700 / 18650 Voopoo Drag X Plus was only $35, I also picked up one of them as another backup.

I vape exclusively on RDA's, typically with a 3mm dual coil twisted build with 24 or 26 gauge Kanthal or nichrome-80. 5 or 6 wraps with 24 gauge, 6-8 wraps with 26 gauge. I typically vape these between 90 and 110 watts.

I did not expect to get a 'true' 90-100 watts out of the Drag X, so I set a target of around 60 watts. I mounted a 3mm dual coil twisted 28 gauge build with 6 wraps, which on my Aegis X vapes great at 60 watts, and very good at 50 watts. It measures at 0.45 ohms.

But on the Drag at 60 watts, it only vapes at what feels like 30 watts on my Aegis. Setting it higher makes no difference either, it seems to 'top out' at ~30 watts regardless of the setting. 60 watts @ 0.45 ohms is only around 11 amps, so I doubt I'm hitting an amperage limit.

I am using 18650 batteries (VTC5A), and it is about time to replace them, as I am only getting around 70% the battery life as I did when new. I will be picking up some 21700 batteries at the same time, which hopefully help with things on the Voopoo.

Does anybody have any good experiences with ~60 watt builds on a Drag X Plus?  

Hey folks,

Have been getting into vaping on temp control (DNA40) devices with Nickel Wire builds in RDAs. Does anyone have experience with cleaning these builds to extend life? You can't dry-burn Nickel Wire the way you can Kanthal so I haven't figured out a way to clean these builds other than rinsing as well as possible and rewicking.

Hate the idea of having to rebuild every time but if that is what needs to happen I'll do it.
