Surface Area/Ohm's confusion

[Ali Moorad]

Hey Guys! Hope you're all well!

I recently built a dual parallel coil on my Smok Alien 220 watt using 24 g wire. This was the first time i tried and I've sorta stuck to this build for over a week now (just changed the cotton once).

The thing is, i enjoy the vape. There is a ramp up time (it's like 8 wraps of parallel on each side and since its parallel, it looks like 16 wraps of a single strand of wire. Im using the Tsunami 24 mm RDA) but I've got used to it. I like the surface area and the vapour it produces....But that got me thinking.. and it's a stupid question but here it is:

What's the difference if i just do 16 wraps of single 24 g kanthal wire on each side.... The surface area will remain the same surely and i know the ohm's will go waaaaaaaaay high... But how would that affect the vape?

I mean, i know the dangers of going to low an ohm because you are nearing short circuit and it could cause your battery to exceed it's CDR and lead to venting or exploding. Is there any danger to vaping on high ohms? What would it feel like doing 16 wraps dual coil 24 g... Is it just the ramp up time that will be affected? is it bad for the batteries?

Peace guys and take care!

You have no dangers of too low of a load. You're using a regulated mod.
Because it's regulated you won't notice any difference on a parallel build vs a single with 2x the wraps.
Because it's regulated nothing you make has any difference on the batteries.

The only thing that matters for regulated mods is mass and wattage.
More wattage means more amperage draw from the batteries. More mass means longer ramp up.

I've always held to the notion that if you have to wait on your coils to heat you're just wasting power so if there's noticeable ramp up your build has too much mass or you aren't using enough power.
Waiting for 80w to heat your coils drains your batteries and heats your mod, atty and batteries way more than just dumping 150w into the same build and getting your pull right away.

16 wrap would be higher oh tha 8 wraps in parallel. .. the biggest issue you will have is can your mod output high enough voltage to reach the high watts at the higher ohm rate......

Thanks for the info White Owl! Makes a lotta sense. So i changed my build to about 10 or 11 wraps and spaced the coils out a bit. Greatly reduced the ramp up time and still gives me decent mass/surface area. It's kinda sad, very convenient, but sad that the ohms and builds dont really matter on regulated mods ... Causse ive been doing so much research since i started vaping.. LOL.. Im now feeling liked getting a mech.. hmm...

The build does make a difference, even on regulated mods... more mass means slower heating (and slower cooling), a longer coil means more evaporation surface: those two parameters alone make a big difference to the vape you perceive.
If your ohms go too high with the build you have in mind, change the wire material to stainless steel for instance (which you can use even w/o temperature control), or just start twisting Kanthal wires.
But be prepared to pump more power into those builds.
Mechs for high ohms must be with batteries in series, which can be dangerous if misused. Not that mechs matter much these days - regulated mods have now replaced them for good - it's more a thing for old-fashioned, nostalgic vapers like myself..

Mech mods are far from dead.
They sell out almost instantly or there is a waiting list.
For most of us builders there are very few alternatives.
And you can definitely use a high ohm build on a single or parallel you just can't use a low build on a series.

Not dead, just a niche market. Which is good, for most people today don't know how to use them safely.
Back to the point, 1 ohm on a parallel/single mech puts you at around 15W, which is on the lower end for most of the recent atomizers. With a 2 ohm build you'd be facing 8W.. That's why I said a series mech would be needed for what the OP was thinking about

Start practicing claptons then fused claptons mate you'll notice a big jump in vape performance vs surface area

Dual core 26g with 38g wrap (fused claptons all 316L)

7 wraps at 3mm diameter will come out at 0.285 per coil or 0.14 dual core could always go for 8 wraps on these to up the resistence a little

ramp up is quick

haha! Sweet! I think i tried claptons the first time i used an RDA and i forgot what its like! lol. The thing is, i want to try these builds...but i need a drill and i dont have a drill.. Sure, ive seen some videos where people do it by hand but , as of now, it just seems too time consuming for me.

The most time consuming build ive done so far was my dual parallel that i mentioned in my post....it wasn't just building the coil that took time but inserting it and making sure it fired right and even from inside out and all that other shizz....

But yea, i think ill try building my own claptons soon... i dont find it fun buying ready made coils

If you start making clapton within a few months or less you'll be able to make stuff like this:

I can't use RDAs. It's an augvape merlin RDTA.

What the !!!! That looks crazy af! Damn tank tracks as coils! Hahaha. Sheesh! I cant even begin to understand how that was made!see like 6 wires in there... Seriously though.. you gotta tell me! Did you make this?

I did, thank you.
There are 16 wires in there in total not counting the fuse.

There's much more:
