A bit of all three. Not my friend. But the guy he was shown this build from, works at a shop. They are supplied by royal wire, and they do the competitions and stuff. I only asked this because he explained it to me the way I explained it. He explicitly told me how it was different etc. I think HIS lack of knowledge screwed me up and made me look foolish. That's why I got so defensive, because I was literally just told about all this the other day, and I guess I got some really bad misinformation. It happens yknow?

If that's true, which I'm skeptical, then that royal wire 'sponsored' shop manager is a complete idiot and will get someone's face blown apart. If you know as much as you say you do, this thread would have never been created. Please, please, please, for the sake of your viewers and yourself, spend the next few weeks working with Ohm's Law, reading and re-reading up on all safety articles available, and studying electrical processes.

Ohm's Law: V = I*R which can be solved for the current ( I ) I = V/R

Vaping a build of 0.03Ω daily would require 140A of ~continuous~ discharge. Such a battery does not exist in an 18650 or 26650.

You say the build is a dual coil setup with 22 gauge kanthal wrapped 5 times around a 3/34" bit... This would not produce a resistance of 0.03Ω, ever. Even with the shortest coil legs possible.

The screen shot below shows what the resistance would more likely be... 0.1325Ω. I use this site to predict my builds and it is nearly spot on every time when I measure it (+/- 0.01Ω). Their standard deviation of error is not large enough to encompass a 0.1025Ω difference. At this resistance, the required current is 31.698A which would explain why your 'friend' hasn't become permanently disfigured. It still exceeds the maximum continuous discharge rate of even the best batteries (18650) by about 5.67% which is still not recommended but would work for a 50A 26650 (The New Sony VT's for example).

I'm not intending this to be harsh or to shame you in any way, but please, for the love of all thats good, gain some humility and accept that you need to go back to the books for a little while. Everyone here is willing to help educate, I've asked for help plenty of times.

Reading the first few posts seriously made me facepalm... Not knowing how decibels work...

My advice would be to actually read up on how vaping works... And how electricity works as well... And take some math lessons especially involving decibels.

The reason we build sub-ohm coils is to get more power (wattage). The best way would be to get a device with a chipset that can boost voltage and keep the amp draw to a minimum since you are able to use higher ohm coils... Unfortunately, these types of devices can get pricey and hard to get over 30 watts. For that reason, we drop resistance to allow for high wattage output... But that unfortunately puts excess stress on the battery since we increase the amp draw. The low resistance isn't what makes clouds (we do this as it is a cheaper alternative) ... It is power (wattage), surface space, and air flow.

Though, now it seems that high output regulated devices are starting to get cheaper and a little easier to get. About the only reason to use a mechanical and sub-ohm would be for the toughness of a metal tube with little to no parts to break.

Guys. I never tried to be the end all of knowledge. I specifically meant, the builds that I personally do myself, I know what I'm doing. I use the proper batteries, an mvp, and I do also use a multimeter. The only problem I had was understanding the decimal point, what made it equally confusing is our builds, side by side. I was running a 0.8 ohm dual coil. His dripper read 0.0, however he insisted that his is actually 0.08/.8 whatever. The problem I had was understanding how that could be possible on a Vtc5 considering the amp draw would be insane. I really wish we could get on the same page. I am more knowledgeable thanks to this thread, however my only gripe was being treated like an idiot; I was operating under a false pretense, bad information, and I took it personally because all of the sudden every aspect of the hobby and my knowledge of was ridiculed and in question, in a very rude, condescending way. Thats all. I guess I'm subject to further lambasting, but I wish you guys could get what I'm saying. I Don't KNOW IT ALL, I am very terrible at math, and the guy I got my information from isn't all that smart to begin with!

Thanks, man I appreciate that. But looking back I had stated I believe it was an error, it had been . 8, not 3. Thanks for the useful information.


Looking back, yes I am incredibly stupid. But it was the decimal point that got me, and him explaining to me that 0.8 and . 8 was an entire ohm lower or something.... Not possible. Sigh lol

And...It looks like correct info has been given and received.
