Sub ohm vaping.

[TREX2014]

Hello everyone, this will be my introductory post, as well as a question I have.
I would have posted this into the Medical portion of the forum, but apparently I am restricted from doing so.
With all the news about the study done in new jersey, there has been a myriad of information and posts going around this forum, and others. Before I ask my question, I would like to assure you that I have indeed searched for my answer before asking it. I've come across no real information pertaining to my question.

I use a blackhawk mod and vape at sub-ohm levels. My setup uses a single 18650 battery. The study that the New Jersey scientist did apparently found traces of formaldehyde when the voltage was 5.0 or more. The coils I build usually run somewhere around 0.3 to 0.7 ohms. What voltage does a mechanical mod run at? Does it simply run at what the battery is? (4.2 volts) I am slightly aware of Ohms law, is there a formula I can use to figure out the voltage the mod is using? In your experience, do you believe that sub-ohm vaping creates a significant amount of more carcinogens, if any at all?

I know that on my sigelli I have an option to increase the voltage from 3.0 to 5.0 as well as the wattage from 3.0 to 14.0, but with my mech mod it's simply insert the battery and press the button. It's hard to say.

Thanks.

that study was usinga crappy clearomizer iirc and the formaldehyde was being produced by dry hits. also it wasnt formaldehyde itself but a formaldehyde compound

I use an app on my android phone to find out, at .7 which I like to use, it says the power is around 25 watts, not sure about volts since I don't use those even when I used box mods, im not going to lecture you about learning ohms law etc before using mech mods but you should look into it

and honestly, I breathe that crap in anyways when I drive with my windows opened so I don't care

oh was just thinking, I use the battery strength as voltage measurements which would be 4.2 at full battery, if that's what you mean? if not then I don't know, I just use the wattage calculator

and yes a mech mod runs at batt voltage

Also keep in mind, the parameters they used in those tests. I believe I saw they had like a 100 second draw at 5.0V. 100 seconds... anything will burn dry, and way past dry, to the point of being toxic. Don't listen to the fear mongering, new studies pop up every day with outrageous claims against e-cigs, and are almost instantly debunked, but the problem is the people with the power to stick these ads into peoples faces just keep running them anyways.

Yep. Mechs run at battery voltage, which is 4.2 volts on a fresh charge, and drops as you vape. I typically recharge the battery when it's near 3.5 or 3.6 volts.

You need a multimeter to check your current battery voltage, as that's (approximately) the voltage you're vaping with. If you discharge a battery too low, below 3.0 volts or so, it can cause irreparable harm to the battery, making it unsafe. You need a multimeter for this reason alone, as well as to verify that your charger isn't overcharging the batteries, which can be every bit as hazardous.

You're clearly rebuilding your own coils, presumably using a dripper. I wouldn't worry about the 5 volts thing. The formaldehyde seems to be created by letting the juice attain extremely high temperatures, like the kind created in a top coil clearomizer with terrible airflow being vaped at 12 watts; you couldn't ask for a more perfect storm. We can taste formaldehyde; if it doesn't taste good, figure out why. Most drippers are well-designed to allow lots of wicking, cooling, etc.

However, you really should learn more about batteries and safe vaping practices with a mech. Look up the member Baditude's blog posts, they're a wealth of information.

Welcome to ECF, don't let the junk science get to you, but know your rig!

Hello and welcome to the forum. Glad to have you here!

If you are new to mech mods and rebuildables I highly recommend you spend some time with Baditude (one of our resident battery experts) and visit his blogs. You are now 100% in control of your own safety (and others around you). Make sure you purchase an ohm reader and a voltmeter or DMM so you can measure your builds, check for shorts and measure the remaining charge on your batteries.

Baditudes Blogs. The blogs regarding mods and rebuildables are listed below:

BATTERIES

9. Battery Basics for Mods: IMR or Protected ICR?
* Another essential read to understand which batteries are safe to use in mechanical and regulated mods. Includes a frequently updated list of recommended safe-chemistry, high-drain batteries with their specifications.

17. Purple Efest Batteries Not As Advertised
* A cautionary blog that reveals that the purple Efest batteries may not have the specifications advertised. Also includes a commentary on "continuous discharge ratings" vs "pulse discharge ratings" of battery specs.

OHM'S LAW

14. Ohm's Law for Dummies (Vapers)
* My attempt at explaining Ohm's Law in layman terms and how it relates to vaping.

16. Explain it to the Dumb Noob: Ohm's Law Calculations
* As simple as it is to use, some people have a tough time grasping the concept. Warning: Includes graphic photos of mod explosions.

MECHANICAL MODS & REBUILDABLES

7. Information Resources for Your First RBA
* An essential read and reference guide for someone new to rebuilding coils. Includes a multitude of useful links on battery safety, mod safety, coil meters, coil building, and the differences in the three types of RBA's.

15. Inexpensive Mechanical Mod and RDA Setup
* A response to the frequently asked question on how to get into rebuildable atomizers with a mechanical mod inexpensively. Includes a list of commonly used tools and supplies for rebuilding and where to find them.

BATTERIES - WHERE TO BUY

Only buy batteries from a reputable supplier (not ebay or Amazon) as there are many counterfeit batteries being sold. Here are several reputable battery suppliers in the US.

* RTD Vapor
* Illumination Supply
* Lighthound
* Orbtronics

The problem with the study was not the voltage. Their test conditions, as stated above, produced unrealistic circumstances that would not be encountered by a vaper . . . basically, they created the biggest dry hit in history and measured it

1: "What voltage does a mechanical mod run at? Does it simply run at what the battery is?"
Yes.
It is just a simple container for your battery.

2: Formula:
watts = volts x volts / ohms
volts = amps x ohms

3: "do you believe that sub-ohm vaping creates a significant amount of more carcinogens, if any at all?"
What gets produced depends on temperature, not ohms.
Wire gauge and wicking are important to temperature, not just ohms.

That formaldehyde fabrication is just that - a fabrication. It's junk pseudo science, but for whatever reason it seems to suck everyone in - just because someone said it. It's being discussed here. ~> http://www.e-cigarette-forum.com/fo...ormaldehype-junk-study-released-jan-21-a.html Some news outlets are already doing retractions for having even reported it.

Boom, in comes Susan with a slam dunk! I get credit for an assist, right?

I also wanted to add that I do sub-ohm on a mech all day every day. I'm personally not very worried about nasties like formaldehyde, even though I attain pretty good wattage (rivaling your 0.3 ohm build, which is rather low - what battery are you using, by the way? I hope it's an IMR that's rated for at least 15 amps, as you're getting close to that drain with a 0.3 ohm build).

However, I am looking forward to Dr. Farsalinos's study on vapor composition as a function of coil temperature and may change my habits as new quality information arrives.

Mechs run at battery voltage 4.2 for single batts and parallel set ups, and 8.4 for 2 batts in series. Parallel volts stay the same amperage doubles, series volts doubles amps stay the same. Unregulated the coil will determine the amount of power required. There is always the possibility for undesirable chemicals when heating things. But the amount chemicals released compared to cigs are minimal.

Formaldehyde is naturally produced during burning of organic matter. So it is produced when your burn tobacco and if you burn a dry organic cotton wick. So you may be getting a tiny amount if you vape your wicks dry and start experiencing a burnt taste - e.g. "dry hits." But that's when we all stop and redrip or refill our tanks. It cannot be compared to continuous inhalation of burning tobacco or the extremely long inhales simulated in the recent e-cig study. Emerging regulated mod chip temperature control technology like the DNA eliminates dry hits and any associated by products.
