Coil Resustance

[sub4me]

May sound like a silly question to some but I have a question of resistance of coils that I buy.

Ive noticed msny coils come in a standard 1.8ohm and those seem to sell out fast so I've picked up some 2.2 ohm coils which seem to work fine also. I pretty much understand the higher the ohm rating the more the resistance to the battery power. But why would someone want a higher resistance coil like a 2.4 or 2.6 ohm is there something I'm missing?? I use a vv battery so of course I just adjust it to my desired taste level so I suppose the coil resistance doesn't matter all that much, at least I think it doesn't. But what about using a non vv battery and does a higher resistance mean it drains the battery slower as opposed to a lower resistance coil??

What tank(s) are you using?

I use the H2 tank and an Aero tank.

Higher resistance to the flow of current equals less wattage... cooler vape and generally less vape too...

Mainly a difference for non VV/VW devices.

Just to add a little to that...

There is more to it than just resistance... it's the coil type, wire gauge, vertical or horizontal coil, single or dual, top or bottom coil, wicking material etc. I understand you were talking about the same coil head with just a different resistance... I just thought I should mention how so many things go into the creation of an enjoyable vape... it's why we have things like variable wattage... control as many of those factors as possible.

* I've found a lower ohm coil to be a hotter vape..higher ohm coil would be a cooler vape..I don't buy coils anymore as I drip mostly and wrap my own..even in the kayfun I have to wrap my own coils.. Hope this helps at least a little bit! Good luck figuring it out

OK, but then why would some tanks come with higher resistance coil?? Wouldn't they want to supply you with lower resistance to provide more vapor??

A higher resistance pulls less wattage, and as a result, will drain your batteries slower.

Much slower actually, if you use the steam-engine.org calculator, you'll see that a 1.8ohm coil firing at around 3.6v will last ~3x the length of a .6ohm coil firing at the same voltage.

Higher ohm can give you more range on your VV/VW devices. Lower ohm can limit range on your VV/VW devices.

Lower ohm will give a warmer vape on set voltage devices.

Thanks for everyone's input. I'm happy for the most part with what I use I was just wondering about the different coils and why some come with different ohm choices.

Most of the H2 tanks I buy come standard with a 2.2 coil but the refills my store carries are always 2.4 only that's why I was asking.

It's actually an interesting point, but in the range of 1.8-2.4 one isn't going to notice that much of a difference. In my opinion 2 is about the highest I'd want to go, but 2.4 and 2 is gonna be barely a noticeable difference. And 2.2 to 2.4? Most heads have like a ~.2 range, in that some coils will be 2.2 and others will be 2.4, even if they're marked as 2.2.

Odd... and 0.6 goes in to 1.8 3 times... coincidence?! j/k

Thanks, that explains why I don't really notice any difference in them. I usually vape at a 3.8 or 3.6 vv setting depending on my liquid and remaining battery power and for the most part get great flavor and a decent amount of vapor, at least enough to satisfy me.
