First, "Weaker" is not the right word. The lower the resistance, the MORE current it will draw, and the more power it will use for a given voltage.

A dual coil is 2 coils in parallel. This combination will have half the resistance of just one of those coils (in other words, if you removed one of the dual-coils, the resistance would double).

Oops lol Thanks for the information! Do dual coils last just as long as singles?

BTW, I got a laugh out of your location. :laugh:

My experience is that single coils last longer than dual coils, and perform better than dual coils, too. At least as far as cartomizers go. With clearomizers, I've not noticed any difference at all in longivity or performance.

Duals are a strange thing.
They half the resistance but the coils remain the same.
The battery sees 1Ω but each coil is 2Ω and will cook like 2Ω. On paper everything sees 1Ω but in real life you probably have to increase your voltage or probably have to double your watts.

Then you throw in different wire gauges into the mix to confuse it further and you may not have to increase your voltage or wattage.

About all you can do is try. If you're building your own you can try, and try, and try.

I got sick of trying. I built the same coils I'm happy with in singles and increased the voltage.
For the record I was not at all impressed with the dual coil Iclear that came with my VTR. Once I found out it was a 2.1Ω dual I figured that's why, 4.2Ω coils, no wonder I didn't like it.
 
Im using a mechanicaL mod.. and setting it up with a proper duaL coiL does these things for me: more vapor, (not necessariLy more fLavor, but I do get more when I do it right), more battery drain (because resistance is haLved when using 2 coiLs of the same resistance in paraLLeL)..

You can pretty much get simiLar resuLts with a singLe coiL.. but when you reaLLy want to push your buiLd, you can step it up a coiL. XD

Im reaLLy not good at expLaining myseLf, but I hope I got in enough. :)

I've noticed a few differences between rdas on single and duals...

with duals I get a little more vapor (I think this has more to do with more airflow as I use 2 airholes than from the coil itself), a very little more flavor (I think this is due to the reduced chamber that is now occupied with the other coil and wick) and a HUGE battery drain,


I prefer to stick with singles

On clearomizers, I prefer the single coils over the dual. Less battery drain as others have stated and no notable difference in performance or vapor production. Additionally, on the Aspires; they become a juice hog.

On an RDA, I prefer the dual coil set up but that is the only time I would say that.

Dual coils are an UNNECESSARY added cmplexity

Totally agree. I use single coils on my Provari and mech mods, don't bother much with duals anymore. Even on the regulated Provari using a 1.4 ohm single I get a thick, dense vapor that is absolutely fine. On a mech I go as low as around 0.7 and it's plenty, sometimes too much!

I would say for me, dual coils are for cloud chasing, singles for every day use. Some of the Pinoy vapers using mechs throw some insane clouds using the traditional wire wrapped around silica x 2. I would always recommend trying a build just for the fun of it, but I get zero advantages and the negatives of reduced battery life, using twice the coils and juice, and more fuss than I want.

It depends on the design, in general dual coils are meant to produce more vapor, its twice the wire, in contact with twice the silica, heating twice as much juice, and usually draining more power.
The Kaifun and Taifun design use 1 coil and perform like champs, now you'll see the cloud chasers using drippers set for dual, or even quad coils and more.
So I think there is no such thing as what is better but what you personally like the most and to find out requires trying for yourself.

What's the difference? I also notice that the dual coils seem to have lower ohms than the single coils, any particular reason or have I just been finding the weaker of the dual coils?

Ok so you got a tank like a protank;
It comes with some coils, lets say 2 ohm coils.
Let's say some are single coil 2 ohm coils and some are dual coil 2 ohm coils ( 2 4 ohm coils in parallel).

You vape your stuff at 3.7 volts; you end up making more fog and vaporizeing liquid faster with the dual coil.

Maybe you keep buying replacement coils, but if you rebuild your coils or even just rewick them, it's going to be real hard trying to keep those dual coils running; chances are you'll just rip out the dual coils and replace with a single coil.



Now if you had one o these little babies:

you could put one up to 4 coils! but this one's a dripper; no tank.

I've always used single coil, but just got some Mini Pro 3's with replacement coils pack.
It came with 1.2ohm and replacement coils are 2.2ohm..
I admit I do not fully understand how dual coils work.. So what volts would you guys recommend using them at?

I'm using a Kanger Evod vv 3.2-4.8 volts

Start low and move up.
Standard volts is 3.7 volts.


On a vw device, standard watts is 5 watts per coil;
Try 8 watts on the dual coil

Not sure if you have ever used a W3 or not but the deck is rough to build on. Quad coil setups require WAY to much work to get to a usable ohm level and really has no advantage over duals IMO.

I use to be perfectly content with my Ce4 clearomizers. Then I tried an Aspire ET, BDC. I noticed a much better vape right away. Thicker, richer, stronger. I assumed it was the dual coils, but it could very well be that it's bottom feeding.

It would make sense that the dual coils would be better. Pretty much the same reason cloud-chasers covet sub-ohm vaping. Lowering the resistance of the coil increases the power generated, since you're able to flow more current.

However, I think they're making the dual coils in the same ohm range as the single coils. 2 ohms is 2 ohms. At the same voltage, each coil in a dual system will generate less heat, most likely extending it's life. Also allowing you to use higher voltage.

I know 4.5 volts on my single coils & the vape is too warm for me. On a dual coil I can vape more regularly around 5 volts.
