How are you firing a .19 ohm coil with a dna 30? According to datasheet from Evolv it will only fire down to .5 ohms, in addition, there is no step down circuitry in the dna 30 so there is no way you're going to be firing a .19 ohm coil at 2.8 volts.

You most certainly can fire at .19 and I am certainly seeing the voltage reading correct at 2.8v
many videos on youtube showing the true dna lower then .5 here is just one

I am using a clone and I assure you its firing at .19 even though the mod doesn't see it due to it being .3ohm programmed so below that will never show, it will always read .3, The build is easy to try for yourself duel stovetop coil 4 turns started around a 20g blunt needle with 24g kanthal and in an authentic Zenith. showing .19ohm on my fluke meter and .22 on one of those crappy little ohms reader devices, so no matter its still below .5 and is firing up just fine, the voltage is being read directly from the mod while its being fired and while that's happening the Ohms are flashing showing unregulated due to being below 4 volts. My paperwork say its between .3 and 3.3 ohms but it does go much lower I can toss a .10 build on and see it would fire my guess is yes, do I really want , not really but I will if it will satisfy curiosity

Just to be clear : I just got my first DNA device - when firing below 4 volts and it blinks, that means it's firing unregulated from the battery?

Lets say you have a build in there that you want 3.8 volts to achieve a given wattage under 30 watts - as long as it's under the 10amp and 30 watt limit it will fire using the battery's voltage unregulated ?

Not new to vaping but I'm a new member so I know what I'm talking about somewhat. Anyways my question is what are the pros of having a DNA over a Mechanical mod besides the safety and consistency at 30 watts? I can go well over 30 watts on my mech. But lets say I were to put a micro coil on a mech with fewer wraps at .58 ohms with my sony 18650 4.2v charged (Which adds up to 30 watts) compared to a 1 ohm micro with more wraps at 30 watts on the DNA 30. Would the DNA 30 have more vapor because it would be covering more surface area at the same amount of watts?

Main advantage is high power at higher resistances and ofcourse safe, regulated vape!


Except Wizard evolved apprentice, dna20/30 mods are huge compared to kicked 18350/18500 mechanicals. Then there is the high price and possible problems with circuit board/buttons etc...

I love machanical clones because of the size, looks and price. They will last forever and i can put in/take out the kick module anytime i want...

I would probably buy small tube dna30 mod for fair price! 250 eur isnt fair...

RAWR I was looking at a friends ZNA30. Man that's a sweet little device its only a little larger then a mech and built very nicely.

3.1 inches = 79mm is really small, mine 18500 mechs are about 72mm! But zna30 is expensive even in usa, let alone i have to pay for shipping to eu and taxes and its frequently sold out... Maybe some day i will make my own dnaXX device out of mechanical tube and some parts! :)

Yeah I have the same issues getting Micro RC plane stuff form your side of the globe. Customs hold up everything these days also so getting it in a timely manor is outa the question.

I have 3 DNA30 chips OTW, I was considering a ZNA type device after messing with my buddies. I Have a full Machine shop and can cast aluminum, bronze and brass to be machined down. Rite now I'm making a box mod mold to be cast in aluminum for a duel 18650 build.

Man, you can make huge piles of money! Make 22mm, dna30/sx chip powered stainless steel tube mod for 18500 or 18650 battery with quality components/wire and comfortable fire pin for 150$ and you can open factory :)

I am sure that many vapers would rather use tube dna mods than box mods.

I like sleek, flush look so no box mod for me, thanks! Well its a bit overpriced imo and i am sure for many other vapers also. There will always be buyers because we arent talking in tens of thousands or even more devices.

I agree for the most part the better mods are high priced, but at the same time I understand the cost involved. It takes some ones time to draw up the design in cad program it into the equipment making the device, have one made check all the measurements to insure the unit ran the part properly, then if it did someone has to remove and reinstall each part and new block of metal for the next, all that takes time each block of metal has to be locked down, Indexed, adjusted and ran through the operation. the cost of the metal alone is expensive. Then you have the Anodizing cost, chip production and installation, shipping of components the list goes on and on. I can cast a chunk of aluminum for about $5 its much cheaper for me to do that from scrap metal then to buy a block ready for machining at $30+ I also do my own type II anodizing and some plating. Honestly If I figured out the cost in materials and my time at my current pay scale it would be cheaper for me to just but a completed unit. I'm a DIY type though and I enjoy doing the work as well as the personal satisfaction in knowing I built it and its built rite. I also know how to Program in C+ so I might have a chip build of my own sometime in the future. I already make my own RC transmitters and receivers as well as lazer drivers and Flashlight driver boards.

I would love to be able to do something like this, but I have large bills and a day job that demands much of my time. I'm getting caught up at work so I hope to be in the shop in the next couple days, I have some parts that need to be made for firearms and RC projects I have had to put off plus I drew up an RDA I would like to make

What clone are you using? Just to be clear, I have a ZNA which as you know is the Evolv chip, I have never tried to fire lower than .5 ohms but I guess I will have to try it out. Time to do some investigating. :D

Is you clone using an Evolv chip? Because looking at the numbers for a .19 ohm coil at 2.8 volts, wattage is over 41 watts and is at over 14 amps, when the min/max specifications for the Evolv DNA30 are as follows, .5 ohms minimum resistance, 3.2 volts minimum input voltage, 12 amps maximum current, 30 watts maximum power, yet you are exceeding every one of these limits and not by a small amount but a significant amount. Not wanting an argument, just trying to find out exactly what chipset your clone is using because I'm starting to think it is not an Evolv chipset.

I'm using the clouper clone of the DNA30 chip as stated earlier the unit will go unregulated below 4v so the wattage figures go out the window at that point. My understanding is that Even the True DNA will unregulated below 4 volts you can see this by the Ohms reading flashing during firing of the mod. Last night I hooked up my fluke meter to the leads of the RDA and fired it just to see if the output at the coil was actually 2.8 volts I got exactly 2.8 volts from the mod unregulated. Here is my take on whats happening when the unit goes into unregulated mode your firing at the voltage determined from the resistance of your coil per the wattage you set, the unit cant go over the 30watts limit and really shouldn't go above the setting you set it at, but remember it unlatches regulation so anything is possible, I think with the vapor production I still get unregulated its firing at 2.8v and 30w max, could also just be that the wattage is what you set it at, but the voltage unlatches. just not able to go over the units Max settings. Make sense? In regulated mode the vapor production is a little better but not by a lot.

As with any electronic device a manufacturer will set a limit they prefer you run there products at this is for the safety of the product and so your not sending a million units back for warranty repair. Those limits are most times conservative to avoid issues down the road. If I remember correct the hex ohm unit is said to be a 50W unit yet will run up to 60 70 and will run below the recommended ohms rating. Safe to do for the chip only the engineers really know and they are the ones who determine the recommended settings and set the Fudge factor so to speak for safety and longevity of the product.
