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

[Ryedan]

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.

As WattWick said, high watts can be set up to produce a hot or a cold vape. Power does however make the vape experience 'aggressive', as I think of it. Lots of vapor/flavor/TH produced very quickly. I think that's what you meant by 'too strong', but please correct me if I misunderstood. I'm vaping a dual coiled Trident at 0.6 ohms and it's a cold vape. No heat whatsoever. However I rarely take longer than a three second pull and that's when the battery is getting low.

It's not for everyone, but I love it.

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

I'm still in the process of trying different things with the diamond coil, and I really can't say what will be perfect for me yet. Today I'v been playing with a 3wraps/coil 30ga, but I think I will have to change the wrap diameter to get the resistance that I want. Right now I'm at 1.8 ohms, and I can turn the provari down low enough for what I want, but it's a bit much on a fresh bat in the machanical.
If I can't get it right with the 30ga, then I'll go back to the 4wraps/coil 28ga.

Also, that design does not lay flat on the bottom of a RDA, it stands up so that the air flow is through the center of the diamond.

Thanks. I've seen these before but never tried one. Will have to give it a go

I haven't read the whole thread but my first mod was innokin 134, and pretty much the whole time I had vapours tongue from constantly trying to get a good throat hit and taste, 2-3 months into my vaping I bought a reo and vap tongue is gone, every aspect of vaping has improved and because I bought a mech reo we have to adjust the power by building a coil to suit and sometimes and because we can we do sub

but if I did dust off the 134 I would be using a single micro coil @ 1.2ohms in a trident

I just built my first .8 ohm dual coil on a IGO-W with air holes drilled out to 5/64. Using it on my Vanilla Copper Mod. It isn't a hot vape with the airflow increased, but more of a cool vape. It creates a ton of vapor instantly. Mouth to inhale is pretty awesome but a direct lung inhale is ridiculous. I am loosing a bit of flavor compared to my 1.6 ohm builds at 10-12 watts though. I am a flavor junkie so at this point I am not sure it is for me, though it is pretty cool to fog up the car with 1 hit I don't have a regulated mod that will do over 15 watts but my guess is regulated 20-30 watts would be the same.

More vapor doesn't necessarily translate to more flavor… in my experience theres design factors involved that play a part (ie. chamber size, air flow, coil placement to air).
I don't know the specifics but only a couple of the high end dual coil attys gave me good flavor (Kraken genesis, and Origen dripper)…

ymmv of course. but again clouds do not always = best flavor. I love lots of vapor but if the flavor diminishes, not interested.

I wouldn't vape my KFL with a 0.8 ohm coil. Nor would I vape my gennies with a 1.8 ohm coil.

Lol that's exactly where I like to Vape my kayfun, absolute bliss

I blame mine on user error. I coiled it like I would coil my gennies. I'm sure there are better ways of achieving 0.8 ohms in a KFL and get a brilliant vape. Not even those who prefer a hot vape would like it the way mine was.

?????

The point of subohm coils is to draw a certain amount of power out of an unregulated power source. You will not get the desired power output with a higher impedance on such a device.
If you do use a regulator to get the same power level, you will incur the same or greater draw on the battery.

 

[Dusif]

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.

I wanna know as well... Im thinking if a magic coil at 2,5 ohms can make clouds as a 0.3 dual coil can... What can that magic coil do at 0.3 ohm dual setup?

i imagine its about missing a factor of what makes sub ohms vaping brilliant.. ie. i'd guess wicking; not enough juice getting to the wick to keep up with the heat.
.8 is pretty mild for sub ohms, but without enough juice, its going to be bad.
