Not that long ago, I let a guy who was a firm believer that only mechs could supply his power needs screw his atty onto one of my dna 20s. He thought he was vaping at right around 20 watts on his mech, so he immediately turned the power on the DNA up to the full 20 watts and the result... He scorched his wick. This was obviously an unscientific test (no actual measurements were taken) but it's also clear that his mech wasn't really putting the voltage he thought it was into his atty. :D

I have a DNA 20 and although i don't use it much anymore, i did use it for subohms and found that ie a .6 ohms coil would vape decent at lower watts too…
in my case, after getting panned on threads "DNA is not for sub ohms… its counter productive"… i shelved it because it needed to be on a pass thru as batt would go down in half an hour (18650IMR)

I'd like to point out that have not asked our host in this thread to change a thing about the mods he's making.

True, I've noticed you've made a point of being clear about that. Not that there isn't room for dissent, should you feel the need. I'm open to ideas always. I may not be able to or want to implement them; but hey. I did intend to design something that was very moddable on such things as contacts, connections and materials. Although it's not particularly moddable re: having extra space to add parts, I'm open to such requests . . . . as a certain mysterious person has just had fulfilled (wherein they are receiving an extra bottom section piece and copper plate).

the only way I would attempt it would be to do it all in an extended base, which shouldn't affect how it feels in the hand.

Don't be shy to ask.

I've been reading about all the ohms and watts for months... and I'm finally at a point that I think I (kinda) understand what is going on...

This last from Rossum about the watts on a mech not actually being as high as previously thought leads me to wonder... why does this matter? Isn't the important thing the number of hours of good vape you get? That is, can't you tweak your coils to give you the vape you like best regardless of the amps put out by your mod?

Since you're taking requests, I would like my dibi signed and numbered please:).

I'm curious, have you measured voltage at the atty, under load to confirm that you're really vaping at the power you think you're vaping at? Not that long ago, I let a guy who was a firm believer that only mechs could supply his power needs screw his atty onto one of my DNA 20s. He thought he was vaping at right around 20 watts on his mech, so he immediately turned the power on the DNA up to the full 20 watts and the result... He scorched his wick. This was obviously an unscientific test (no actual measurements were taken) but it's also clear that his mech wasn't really putting the voltage he thought it was into his atty.


I tend to measure the v-drop on every mod I build, modify and/or send out. (voltage at coil . . . . battery and everything . . . whole system voltage). Mine (my unit) tends to show 3.85V on a fresh battery (4.15 off my charger) with a .4Ω coil. That's 37 Watts (real time). I tend to vape it til the battery is at ~3.8V (that's hitting at 3.5V at the coil); and on the same .4Ω coil I'm getting 30 Watts and change.

it only matters in discussion; which is necessary for comparison, innovation, improvement and troubleshooting. You're right that it doesn't matter for your personal vaparoochy. :)

So how much vape time is that:)?

I had a really hard time deciding which to ask for. I changed my mind every time pdib posted a pic. Then I saw a video he posted showing how it shimmers & decided that the Santos Mahogany would be my first foray into BF.

I think this is supertrunker's Santos Dibi caught on tape.



Excellent taste. I'm grabbing the Santos myself in run 7. And the wife just ok'ed dibi# 2 as my Xmas present. Now to pm pdib and see what run #2 will be in.:D

Thank you, sir! :thumbs:

Yep, you are. This puts you right at the threshold of the 33-35 watts a DNA 30 will actually produce into a load (if the rest of the mod has sufficiently low resistance) and means it would add less flexibility to your vape than to someone like me who doesn't run at those crazy power levels. ;)

What it all boils down to is a dance between the air flow, chamber design, wicking, amount of surface area that is being heated, amount of energy put into that surface area, the particular juice, and your own preferences of vape. Get those crucial elements out of whack and no amount of voltage or amperage high or low regulated or not will compensate. I currently get a full day of satisfying vape out of a single SX30 18650 (most days) vaping at .7 ohms going through about 6 ml of juice on OliveR. I also have a bottom feeder that is capable of over 100 watts regulated from .6V to 5.5V up to 20A, but it is the OliveR (with a Reo for backup) that I use daily due to ergonomics.

So how does most juice handle that level of power? Some juices tend to burn easily.

Judging by the love for nicotine extracts here, I'm thinking that most of you are vaping relatively thick and particulated juices (because I do tobacco extractions too, and even running through cheese cloth 3x and then a syringe filter 2x, I'm not able to clear out the particulates because they are insoluble). This makes sense when I read that some of you are rewrapping coils multiple times a week, particulatey juices burn and make more carbon on the coils.

What else are you vaping on the sub-ohm? Can I get a list of favorites:)?

Is the regulated one the DNA30? I thought that maxed out at around 50 watts... it goes to 100watts?

hey guys/gals... i don't understand how people can vape at 50w let alone 150w and all this jazz... obviously its just me because some of you are vaping 0.2-0.4 np's... as soon as i hit 0.5 sometimes i can feel the juice trying to blister my tongue and give me a rough throat.... is this really a situation that it really does just come down to air intake too small or are any of you guys with lots of airflow like me also and can only vape cool?

sorry for hijackin in here dibby mate, maybe i should go make a thread :unsure:


i feel like a soft lad enjoying my triple twisted 32g A1 kanthal 1/16id 8wraps and 1.1ohms single coil on my mech when i coulda done that on my tubesteak :lol:
