Weird, because Evolv themselves list it as having a minimum output voltage of 4v.
Replace "Subohm" with "High Wattage"

So it would regulate a fresh battery down for 7W on a .65ohm coil?
I'd have to see it to believe it.
They also say the minimum resistance is 1 ohm. So those specs are ... conservative.
No, but so what?
No, the point is the voltage. People doubted whether the DNA20 could operate with regulation on a .65 ohm coil. It can.
It always accurately steps down voltage, to the hundredth of a volt.
Don't confuse dropping out of regulation with inaccurate regulation. The DNA20 regulates extremely accurately always. There are certain conditions when it cannot regulate, and in some of them it bypasses regulation. That's just the design of the board, on other boards you might get an error thrown. You would not say those other boards are inaccurate because they threw an error.
Ironically if it behaved how pbusardo wants -- regulating as low as possible below the cutout threshold, THEN it would be inaccurate.

Unless you're trying to regulate down below a specific voltage to achieve a certain wattage. Theres still a limit. Which you confirmed yourself.
Granted, 7W on a .65ohm coil may not be ideal for you (or maybe anyone for that matter) but it still doesnt eliminate the fact that it does not ALWAYS step down voltage correctly to match the wattage selected.

In any event, this doesn't mean the board can't regulate subohm because it can. Lots of people do it. It's not a problem to run the wattage up because ... that's the point.

So if you set 15w on a .65ohm coil, would it step the voltage down to 3.12v?
Or would it just run unregulated and not actually put out 15w, but higher?
I'm not trying to discount the device. I think it's awesome for what it is. It's simply curiosity prompting the questions.

And to elaborate, the point I'm trying to make is that it doesn't regulate accurately ALWAYS. It doesn't mean that until it hits the cutoff, that it's inaccurate. But always is a bold claim to make, when in fact it does cut off, and does not regulate at a certain point.
Does that imply or mean that there are other regulated devices that can accomplish this? Absolutely not. I'm speaking only about the DNA20. I know for sure that a zmax or similar board would take a dump.

It depends on the battery state, if it is partly discharged it can go that low. So that's a little bit of a unique behavior of the board, takes a little learning curve to figure that out.
But here's the thing. The fact that it has these voltage limitations is the reason I don't run subohm much anymore on it myself. Once I realized that the mass of the coil is the main issue, I started to wrap higher resistance coils that were as big or bigger than the low resistance coils. And since the board can step up power, I am able to access the full wattage range without limitations. Not that I run it at the lower wattages anyway but it's nice to know I could if I wanted to.

Again, it does always regulate accurately. If it is in regulation it is dead accurate. The board CAN run out of regulation, which is not a negative, and quite possibly a positive, compared to other boards that would just error out. The board clearly indicates when it's doing this by flashing the ohm reading.

Absolutely. And I think the whole point revolves around the concept of different devices for different people and preferences.
The dna20 may regulate for some people on some subohm coils, but not in every use scenario. And though it CAN accurately regulate for some subohm coils, it MAY not depending on the need/want/preference of the user.
That's all, but my point is also somewhat steering away from the overall picture of this thread, so I'll leave it at that I suppose.
Nice long debate but somehow I think it's moot, because you guys are on totally different pages. Reading between the lines, you all are correct.
dr g and the OP are approaching this from the point of view of the act of vaping, where most (if not all) people who use sub-ohm coils are vaping them at high wattages. In that case, it is proper to call it high wattage vaping (because it's exactly what it is).
ClippinWings and bulldog63h are referring to the coil itself, where a coil of less then 1.0 ohm is sub-ohm. That is correct too.
If I may chime in, you can achieve high wattage vaping with either sub-ohm coils at lower voltages or high-ohm coils at higher voltages with potentially different vapor and flavor results. In my opinion, just saying "high-wattage vaping" is not specific enough. The amount of watts achieved is the end result, but it is also good to know how that said wattage was achieved. In this case, using "sub-ohm" or "high-ohm" to describe coils used would be helpful.
There is still a place for the use of the term "sub-ohm" IMO.

No one is saying not to describe coils by their resistance, although the 1 ohm mark is ultimately arbitrary. Sub-ohm as shorthand for the entire vaping style is the issue.
I'm pretty sure you meant:
"this doesn't mean the board can't regulate High Wattage because it can."
LOL

So, if I'm reading this correctly, if you are running an insanely low resistance coil, to the point that the board can not drop the voltage enough to match the set wattage, you could actually vape at higher than the 20 watt maximum. Am I understanding that correctly, or is it just way to early for me to brain?
I'm not sure how reliably it can do that. I have not been able to do that but I also have not tried too much. Some have reported good results from doing that, I don't get great voltage, maybe because I do have ptc protection in all my mods.
