Coils for my first RDA

[vaper1960]

I'm getting this kit that comes with a rda:
Aspire Quad-Flex Tank Survival Kit
My only mod is a little innokin EZ Watt:
Innokin EZ WATT 35W Starter Kit | Vape System
My first goal is make a coil for testing new DIY juices (also my first time doing this) The mod only has a few wattage settings: 13/14, 16/18 and 30/35. I'm thinking 18 watts might be a good choice. Any suggestions for a coil build?
I also want to try a little cloud chasing (nothing big... I'm really more of a MTL or restricted DTL vaper) and thinking 30 watts might work. Suggestions for a coil to do this? I only want to get one spool of wire to do both, and the first build is priority right now (I can hold off on second build if different wire is needed)

The survival kit comes with two Clapton coils. I believe they are Ni80, b 0.85 or 0.45ohm. don't remember specially, but might be ok at 30w, depending on air flow. I'd try one first, rather 2 in parallel.

For lower watta, I hear kanthal is the go to wire type, and 26g seems to be what people gravitate to for starting out. Sorry I can't be more helpful in that aspect.

I will suggest a decent pair of ceramic vape tweezers. The ones that have the crescent to grip tanks with. They are invaluable. I picked up a little kit from wish. Was like, 8$ shipped.

Wow! Just watched a video review of this kit and I'm blown away. Had no idea how versatile it is. I also already have coils for the Nautilus X tank (that should work great with my little mod) Will only run one of the supplied coils and can't wait to build my own (yes kanthal would be my choice) Wish my mod had more power, but will see what 35 watts can do. I have never used anything but MTL tanks... I'm so excited!

30 watts is all that I have ever needed from any of my regulated mods, and I'm a DTL vaper.

If you plan to use your mod at 30 watts, being that it has only a 1500 mah battery inside, expect your battery to drain much faster than before.

I have that kit. I have mine built with 24 ga. Round wire @ .2 ohms. It is a velocity style deck so I would go with round wire or single core claptons. The screws come in from the sides so to use flat multi core wire you would have to twist the legs 90°. It is doable i just find round works better. I use mine for squonking and it is nice because it has a cap for that wiith really high AF. No leaks at all. I would suggest 26 ga round wire for you. I haven't used my Quad Flex for a while. I may put it back into service for a while.

A few disconnected observations:
Clouds are proportional to surface area and wattage.
Fancy convoluted coils have high surface area. They also have lower mass so they heat and cool more rapidly, which is important for large coils.
Ni80 heats more rapidly than Kanthal.
At 35W you won't need to be picky since your coils will be small.
It's hard to vape at higher than 100W due to problems with heat dissipation.

Pardon the sloppy build, but you can see there is not a ton of room for massive coils.

Really like this cap. Airflow comes in at the top

And exits at the bottom just under the coils. It has a notch to line up airflow and makes it easier to unscrew the RDA.

 

[HigherStateD]

Hehe... I did try and fit 4 parallel Clapton's in it. It got awefully warm at about 80w, but worked. Enough room at a 2mm ID.
also not sure why vaping over 100w isn't realistic, I often vape well over that. Not on this atty though.

With one or even possibly 2 simple coils of 26g Ka1 or possibly even Ni80 you should have a reasonably good MTL or restricted DL Vape on it.

I eagerly await your review.

I want to start simple... round wire. Which has more resistance, Ni80 or Kanthal (same guage)? The coils that come with the kit... what ID are they? I'm total newbie to building coils... is there a simple calculator for this?

Steam engine is the go to coil calculator. I am unsure of the coils that came with it. Sorry. Kanthal should have the higher resistance at the same gauge. Resistance doesn't always mean lower wattage though. The amount of metal, ie mass, does. It takes more power to heat more metal of the same type.


Also, heat flux is important too. Ni80 and SS316, for example, heat and cool faster than kanthal.

Also, heat flux is important too. Ni80 and SS316, for example, heat and cool faster than kanthal.

Heat Flux is a measurement of radiant heat. With Steam Engine this is calculated by 1 watt/surface area of the coil. Specific Heat is not part of the equation which is the time it takes for an object to heat up to a specific temperature. Steam Engine calculates its Heat Capacity as Specific Heat Capacity of the metal x Mass of the coil.

The true calculation for time it takes to heat an object is: Delta Time = Specific Heat Capacity x Mass x Delta Temperature / Power

Edit: This does not account for juice saturation and or air flow of the atomizer – both of which are difficult if not impossible to factor in.

Higher State... thank you. That is what I needed (remember everyone mentioning it, just wasn't actually ready to build coils yet) The coils that come with the kit are clapton (two coils) so dual claptons it is (I assume they will almost laugh at my 35 watts?)
here's the review I watched (a bit much, but he does touch on the highlights of this kit!)

Drunk in Public (just kidding), I love dogs and cats... right now missing my cat (his name is Jack) He looks very much like your pic (long story... he's with my wife... another long story... separated by location but she is still my soulmate) No worries, math and calculations are a great starting point, but good ol empirical testing is what matters in the end.

You are absolutely correct in that objective numbers may not equate to real life experiences given the many variables involved. But!!! They can be a true benchmark in which we can reference!

BTW – my handle was suppose to be Drunk In Public. But I was drunk at the time so it came out as Punk In Drublic.

And the profile pic is my kitty, Princess and evil genius (all cats are geniuses) named Zelda. She is awesome!

And all this time I thought it was a reference to NoFX.


@vaper1960 you don't have to install both coils at the same time. That should give you a nice vape @35 or less with just one.

 

[uthinkofsomething]

Yes, start with one coil, learn how to get it going good and eliminate hot spots, use low wattage at first, you don't want to make it glow white hot, just barely orange.

I have dual alien claptons in my Brunhilde, I'm vaping at 42.2 watts and it's a lovely smooth vape!
And Talk About Clouds
You don't need to vape at 380 watts to be happy and Cloudy, too hot too hot

Not disagreeing with you in the slightest, but it still depends on the coils you are using. My coils in my tank would taste like wet air at 45 watts. I'm at 87.5. These are 2 round wires and a flat twisted together.
Voltage is in my mind a better comparison. Most ppl are vaping between 4 and 5 volts, regardless of the watts...

 

[charlie1465]

It's all about coil mass so the higher the mass the more wattage needed to ramp up the coil. And as far as coil ramp up goes a higher wattage is not necessarily going to produce a hot vape

 

[vaper1960]

I watched a review and the 2 coils that come with the kit used together (in parallel) is just under 4 0hms so I assume 1 of these coils would be around 7 ohms. How would this do at 30 watts? Most review using both coils were running at least 50 watts.
