8W on a stock Nautilus 1.8ohm coil measured 473 degrees.

Actual temperatures inside a Nautilus atty | E-Cigarette Forum

My experience with 8 watts on an N minni is it feels cooler than my usual 16 max watts and 380F max temp settings. Below is a recent article by Dr. F. I like the article because he proposes reasonable and prudent responses to many of the common ecig scare stories. He also seems to stick to the idea that if there is any liquid burning it will be immediately noticeable by a foul taste.

I, and many others (including many professionals) disagree about the "you can taste it" thing. There is a range on the lower end of the thermal degradation curve where the average person cannot taste it.

To quote another Phd, "I also agree 100% that at the lower temperatures that generate formaldehyde people can't taste what they're doing." and another quote "The other, more insidious one is "I can tell by taste if I'm running too hot". The answer to that is No, no you really can't, until you're so hilariously too hot that you might as well be smoking."

I wholeheartedly agree, validated by my own testing.

I suspect atomizer design plays a role in the perceived vapor temp, i.e. a top coil would feel warmer than a bottom coil but have the same coil temp.

Sitting down, facing forward.
The bottom line is that unless you actually measure the coil temperature or the coil temperature has been measured in the exact same atomizer power tells you nothing about temperature and is not a guide to staying in the assumed safe zone.

I have wismec reuleaux 75w bought for completely other reasons (the ergonomic firing method - squeeze don't poke) with a full size Nautilus on it now using a whole 12W of it's capability. I'm shopping for a tank that has TC ready drop in coils.(suggestions welcome) I can't physically make or wick my own coils, I've tried but it just isn't going to work.

I've been using Innokin VV3s with Anyvape Davides, a combination that is light, and with the VV3s square shape easy to feel and hold on to. The Wismec was recommended to me when I was bemoaning the fact that I just can't find the VV3s any more. I like it, though it is heavy to hold long, and I'd better get at least 1 more before the single battery size is gone forever. And as a retired techy I figured that I'd have to try out TC because it's there, but after ready a good share of this thread I'm putting getting that tank and another Wismec at the top of my discretionary spending budget.

I run the Nautilus on the highest airflow it has, and the Davides are airier then that - that's why I've preferred them over the similar protank. I have three systems with different flavors going at all times alternating among them, at 7-9W with 1.8 or 2.2 ohm coils. I prefer to stay at 1.8 but usually stock up on sales and can't be too picky. I make my own liquid 65-75% PG, and very light on the flavoring amounts compared to the recipes I've seen other people post.

So (there really is a question here) I'm wondering if I can keep tootle puffing away on the VV3s with Davides in relative safety or should I be rushing to get 2 more Wismecs and whichever TC compatible toppers I find?

I havent tested the Davides so I have no clue as to what temperatures they run at.

My personal recommendation is to go TC, attys with stock TC cartridges are somewhat hard to find, but they are available.

I doubt that highly Reduce. My tanks that are wrapped in metal tend to get hotter more quickly as do my tanks that are smaller... A nautilus coil in a Kabuki for example is going to give different results. 3 ml capacity vs. 1.8 (if you use the fill line) different type of airflow, and etc. I was gifted an IJOY Elf tank that uses the N2 coils and it has a metal housing but is overall better designed with more capacity-- if chainvaping it will heat up more than the Kabuki but less than the N2. I love the N2 tank and there will always be one in my rotation, but every tank is slightly different in design, capacity, airflow and etc.

Just my thoughts on the matter, I haven't tested my tanks (other than a kind of-- wow I've been puffing on this a while how hot is it-- type of way, but I genuinely believe that more than the coil matters.

Using h20 in my max VG at 10% was a VERY useful recommendation too-- the vape was so much better, which I wasn't expecting, but I really almost never get "hot" tanks anymore unless I really work at it. It's also better FLAVORED, which I was not expecting at all, so I'm glad that I tried some of the recommendations in this thread (I really am sensitive to PG except in the most minute quantities, it makes me hoarse.

Since you were measuring inside the N2 coil, would it be correct to assume that any tank using the N2 coil will be in close range to those temperatures.
No, not really, there are many variables like airflow, juice flow, atty design, etc that also come into play.

My measurements are only valid for the specific atty, coil, etc that I measured. I would not feel comfortable extrapolating that info to other attys.

Thats the thing with VV, VW, and Mechs, temp is so dependent on so many variables that one cannot just make blanket assumptions. Every different combination of the variables below could result in a different temp. Change any one single variable and it could easily change the resulting temp.

And YES, it does apply to Mechs too. A Mech is basically like a VV mod that steadily declines in voltage. Mech users can repeatably build a coil to a certain heat flux using Steam Engine or whatever, but the resulting temp can still be very different depending on how they wick it, the design of their atty, airflow, juice flow, and all the other variables below. Heat Flux just replaces the "coil" variable, and is only one of the variables in a Mech, all the other variables still apply.

Thank You Mike for continuing to offer to test our particular setups temps when possible. Nothing has been as informative and helpful for me than having a real measurement of what's happening in my topper at power levels I actually use. Vapers helping vapers has always been the best part of ECF and you took this to a new level!

I'm still surprised more wattage/voltage vapers haven't gotten these answers about their vape temps. For the first time there's no guessing with non-TC toppers and a pretty complete look at all the variables. I have found this information to be priceless!

Hi, Amoret. I don't own those tanks, so I can't speak from experience, but ProTank coils (that you use in your Davide ?) are no longer recommended--they heat up too fast; it's a combination of very high resistance wire and not enough airflow and cool eliquid in the coil to keep things cool, IMHO. I wouldn't use any ProTank/Evod type coils anymore.

Nautilus is better and you can get Ni TC Nautilus coils (and Triton mini Ni coils that are compatible with Nautilus tanks) if you want to try TC. Nickel coils got some bad press originally, and some folks claim that they can taste the nickel, but you may want to give it a try. I believe that nickel does TC very well.

A tank that comes with stainless steel drop-in coils is Subtank mini (or Toptank). They are OK if you want to avoid nickel.

If you need a nice and inexpensive TC mod, I highly recommend Wismec Presa 75 watts or Wismec Sinuous P80--they don't have a fire button, instead, the whole side panel is a power button. Very ergonomically designed and easy to activate--you just squeeze the whole thing. :D

Good luck!

Thanks - trying to find a drop in coil tank to do TC has involved reading a lot of product descriptions.:blink: It's good to know that there are available TC compatible coils for the Nautilus, and to know about some other possibilities.

I got the 75 watt Wismec Reuleaux on a recommendation for the squeeze power 'button' and I like it well enough that I was planning to hit Fasttech for 2 more @ around 25$. Everyone seems to be going for 200 or 300w now, but of course those take more batteries, changing the shape and weight. So I figure I better get more 75s before they're all gone, too.

I've played around with the Wismec/Nautilus combination now up to a whopping 16w now and am truly (not) impressed by the really high amount more liquid I go through.

And thanks again for recommending the light, square VV3s 4 years ago, in my first pre-vaping thread about what to get for wonky hands.:D I've kept happily using them (with a few side experiments) until they're now no longer available.

So, while on vaguely on topic, where's the DNA 250c for the holidays. I've been sitting in anxious anticipation and I'll have no new mod in my stocking. [emoji37]
There are rumblings, and vague innuendos, abound.
All I can say, it is really going to happen, just dont know the date, I wouldnt look for it under the tree though.

That study addressed the issues of atmospheric exposure inside a vapor shop. It sounds an awful much like the CA dept of Health results that came out sine time ago, and I wonder if this is the same study. There were no workplace associated exposures, the same as in CA and the same issue of food in the nic refrigerator was the same. It’s a great study if safety fit second hand vaping, but doesn’t really address the inhalation of formaldehyde and other VOCs when actually using a mod/tank. Still good to show you’re not endangering the public by vaping near them, even in an enclosed space.

@mikepetro I am curious what you think about this study from the CDC on formaldehyde in vapor:
New CDC study officially debunks ‘vaping and formaldehyde’ myth
It tested "air quality", akin to passive smoke, in a room. That is a lot different than the concentrated vapor stream we are inhaling. For example, my formaldehyde meter didnt measure anything in my office at all, but it definitely measured increasing levels as coil temp increased (above a certain minimum threshold) when measuring the equivalent of a standard puff.
