Who prefers single coil on their RDA's?

conanthewarrior · Jun 22, 2015

Hi people. Hope your all OK.

Today I have been doing some more experimenting with my RDA, I've found I like my coils around 0.9-1.1 ohms.

Now, the thing is if I do a dual coil build, taking into account extra wraps to make around a 1 ohm dual coil setup, I find it produces less vapour than a single coil at the same resistance and power.

I find it strange that in this case 2 is not better than one, does anyone else find just 1 coil to work better?

It's not strange at all considering your 1 ohm dual coil consists of two 2 ohm coils , also your wattage is split between your coils , if you're running at 20 watts , each coil is only receiving 10 watts . Solution when running duals : increase your wattage or lower your resistance , or both .

Ahh, that would be why then, if each coil is only getting half the power, thats why I get less vapour. My device tops out at 30 watts, and I like a build around 1-1.2 Ohms. I usually run a single at 20 or 25, so if they are only getting 15 that would explain it. Damn, I need more watts already. Or I could build lower, but what would I need to aim for? I have no idea. Do I halve the resitance to 0.5-0.6? So build two coils around 1-1.1, and end up with that?

Also, I don't understand the no comment answers, I am slower than most people yes, but I don't think thats needed, I didn't realise they received half the power, I now understand. Thanks to retic1959 for answering the question for me.

Play around with it and learn it. Once you have a little knowledge with it, pay close attention to the 'heat flux' when configuring single or dual coils. This has helped me tremendously when playing with different coils.

Dude I have run a few .8 to 1.0 monster dual coil set ups and had to turn the powa way way down, seemed to scorch the juice at my normal sweet spot.
Now it is .4-.5 all day every day but YMMW

For me it depends on the rba My single coil freak show hit amazingly. In my opinion single coil works best for flavor in the freak show. Took 25ga kanthal wrapped 30ga around it then coiled that 5 times around the allen key that came with my derringer. Vapin at .3ohms works great for the mech too. My derringer i prefer dual. It makes tones of flavor even though it gets hot as hell (i keep meaning to get a long tip) tanks i build with parralell coils or single claptons these are my favorite for thick flavorful clouds

I love single coil rta like the lemo 1&2 and the subtank mini I rebuild the stock heads with ni200 and titanium since its so easy to pop the cap off and insert a wicked coil like factory.

I preferred single coil in a tank and really wish I could find a good one for Temp limiting. Something on par with billow2 performance. I love that atty but I can't get a good steady performance with a nickel build. I liked the lemo2 but even after notching the chamber I can't get it to wick well with my high vg juice.
For a single RDA ... well ui prefer it actually, but very few atty offer good airflow there, the freak show is one of the few exceptions as of late. Just seems as things are going to the temp limiting the tanks are pulling away. Kind of ashame because that billow2 rocks

Yup , dropping the resistance is the only solution you have short of buying a new device .

I am putting things into perspective, and to be honest I can't really afford another device. I could hardly afford this one and all the bits I got for it, but there is nothing wrong with single coil is there? My Smok RSBT I use single coil as it only has 2 posts, and the el cabron still makes more vapour than I have ever seen with a single, good coil.

The smok with the right drip tip has the flavour of my nautilus, and is rebuildable, but it broke yesterday. The glass broke, luckily I can buy replacements, but I only had it for 3 days before it broke, and I don't think I was being excessive. The break was so clean I could apply a small dab of superglue to the glass(not that comes into contact with the juice) and fix it, it works, I just am going to buy some spares. I just don't get how the same coil works better in one device than others.

Nope there's absolutely nothing wrong with going single coil , I was just trying to give you solutions for the dual coil setup , sorry, I should have been more specific .

one thing you could try is a single parallel coil with 26g or one piece of 26g and one of 28g.

BigNasty · Jun 28, 2015

I wish I could find an atty that would fit this beastly single coil I have. sumbitch is like a bass string gone all crazy.

I built a parallel coil out of boredom to 0.5, it actually is OK. I don't usually like low builds, but it still needs about 20 watts chucked at it. I have some 30 and 28 gauge on the way, will I have more luck with them?

I like my el cabron as it has the airflow setting for just one coil, or two for duals. The one is still quite airy, but not as airy as both, I imagine with the right coils/power it will be a beast. Well it already is in single coil, just want to get the same dual if possible. If not singles fine.

smacksy · Jun 30, 2015

I like single coils in my subtanks but nothing beats a good dual coil build in a RDA for clouds like these

That's a dual .3 ohm 24g build in my Dark Horse/IPV3 at 60w ..good flavor too...

If I increase the gauge(go thinner) and build to a slightly higher resistance, will there be more chance 30 watts will be good? Thats up to 15 watts a coil, I know that I can comfortably vape at 10 on my RTA and for clouds 14.5-15 is fine.

I will have to show a video or picture of the clouds I am getting with single coil, they are quite cool. I'l upload to youtube some.

conanthewarrior · Jul 1, 2015

EDIT: Due to it being a white wall behind me, vapour was obviously not visible. I will make a better video as that one was on my phone for practice of filming myself. When that is done, I will upload.

Possibly, or a combination, on a single bat mech I sometimes use one pics off 28 or 30 and one piece of 24 or 22. Sometimes I sub out the thicker wire for a piece of triple twisted 28g. You just kinda gotta play with it till you find what you like.
This is the part of vaping that makes me really enjoy it as a hobby. I just got a new velocity last night and was trying to find what build on it let it run best for me on my sxm, I went through 6 different builds only to go back to 22/28 dual parallel coils.
if I had 30w to play with and I wanted a single coil, I would first try 24/28g parallel at 3mm diameter 5/6wraps and work from there.

Ok, if you had 30 watts and wanted to make dual coil, what would you do? As I am happy with single coil so far, but want to get duals firing. If worst comes to worse, I will get the sig 75 later in the year

Simple, I would either do 7/8 wraps at 2-2.5mm of 28g or 9/10 wraps of 26g, if memory serves you can go as low as a 0.5 so you want 2 1 ohm coils, just mess with the AFC till you get the airflow, vape production and draw where you like
I don't know much about the atty you're using but coil placement can really help or hurt as well. You'll want a clear path for airflow between the coil and airsource as well as try and place the coils above the airflow with a direct line of sight to the Air-Holes and no wick blocking that path.
On a tobh clone at 30w, a 0.5 ohm build with 28g or 26g was a damn nice vape!!! It just took a little playing with where to put the coil and how to wick it for me, I built my two 1 ohm coils and tinkered around till I got what I liked.

conanthewarrior · Jul 1, 2015

Managed it! I usually use a 2mm driver, but I used a 1.5MM driver with about 15 wraps. This one works great at around 11 watts, so another identical should be fine. I just needed thinner coils with more wraps, I have the extra wire in the post as well so can practice with them.

Looks like I'l have duals with no need to upgrade, which makes me happy.

And thank you for your reply! I can go down to 0.3, although don't really like super low coils so far. I've managed to make a coil that works great at around 11 watts, used a smaller diameter and more wraps, so am going to do the same for the other side. 22-25 watts should power it great.

The airflow is great. Right next to the coils, air flows straight over them. Thank you for your advice, I will probably try to get a 1 ohm build BUT am willing to try a 0.5, it just tends to not taste as good to me. Might be psychological. I don't know why more people don't use that RDA though, deep juice well, easy deck, and takes pretty much any realistic coil from 5 to 30 wraps.

f1r3b1rd · Jul 1, 2015

Awesome, dude enjoy it!!!!

That's thin, my only worry would be if its too thin to which quickly. Easily manageable because you're dripping anyway so you may just have to drip more frequently. Sometimes the airflow cutouts dictate what you've got though. Important thing is you found a build you like!!! Awesome dude congrats!!!

If it comes to needing something else, try a 8/89 wraps at 2 mm. -just forethought. lol
