"Less control over your vape" would be more accurate.

The mech stuff follows battery voltage, and that varies constantly from Top-off charge to recharge-point as the battery drains. The main reason all e-cigs before mechs were regulated by some means is to give consistency. Even the cig-a-likes.

A lot of the same effect as sub-ohm can be achieved using a regulated mod and micro-coils, for example, with consistency (My Opinion). Also, a mod could be build to deliver a consistent regulated voltage even in the high amp ranges. It just isn't necessary to do so and is wasteful so they don't build them much. Although I have seen modders building parallel battery circuit stuff, so who knows. Would be bulky.

IMHO, the mech stuff is mostly a technophobe thing...."I can repair it if the apocalypse hits" kinda thing. Who would want a completely unregulated ecig otherwise? Sub-ohm vaping is a fad that saved, or made, the mech mod market. Without it, there'd only be a few (mechs predate the SLR fad as far as I know). We used to make simple mechs from scrap stuff in the early days. I have to say that the mechs have gotten pretty sophisticated with adjustable air flow and locking buttons and such. Nice stuff. But still, not regulated.

In no way can extending the wattage ceiling of your device give you less vape control. At worst it's the same.

Is there such a thing as zero resistance vaping?

No, there's no way that would work because it would generate no heat.

That statement makes no sense. I didn't say extending a wattage ceiling gave less control. And I was talking about voltage regulation vs following battery voltage (unregulated) and answering Arnie's question.

So, just to summarize and getting back to the spirit of the original post, the pros and cons of sub ohm vaping and/or of higher wattage/power vaping are simply as follows:

Pros:
1.Increased Intensity of vape (possibly yielding more vapor, a warmer vape, or more throat hit)
2. More control over your vape

Cons:
1. The higher drain on the batteries results in shorter run times between charges (given a constant vaping frequency)
2. As a result, you will burn through batteries faster (reach the 300th theoretical charge cycle sooner)
3. You will also burn through juice and coils faster, possibly resulting in an increase in the cost of vaping

So, does this sound about right? Seems very simple afterall.
.
I'd disagree with:

More control of Vape:
The VV maintains a steady voltage, whereas in low Ohm using a non vv device you start at higher voltage and move downward, so less control. In addition you have to make your RBA to match your Device/Wick/Juice instead of making an RBA and then regulating the voltage to provide the best vape.

Running through Coils Faster.
The lower Gauge Coils are thicker and I've found them to last longer. I use Ceramic Wicking materials so my Coil Setup last over a month.

This brings up an intersting question. If a vv or vw device is supposed to provide a constant level of power. or voltage, or wattage, how come I always had to crank up the settings on mine as the battery drained to keep a consistent vape? I know you techies have the answer.

Arnie,

I could be wrong here but I don't think you should be pushing your batteries so far that you have to compensate by upping the power. In other words, change them out when they're like halfway drained. They'll last longer that way, or atleast that's what I've been taught.

I used to run my provari 'til it blinked, then I would turn off the led so I could keep vaping without the blinking until it stopped firing. Until some vets pulled me to the side and said, "Don't do that."

But even then I never noticed anything more than a trivial drop in vape. YMMV.

In every VV/VW mod I have ever used, the device does great at delivering the voltage you ask for, so long as the output voltage does not exceed the battery voltage. So if you set your Vamo to 4 volts, it does great while the battery has a nearly full charge. When the battery dips to say 3.6 or so volts, you see the output drop. I have observed this with a Lavatube, a Vamo, and an eVic. I assume this is true for all of the 33Hz mods.

This is not true with a ProVari. The output is constant from the first puff to the last puff.

I should point out these were eGo style vv devices, that I noticed this on. As the vapor became weaker, I'd just crank it up by .10 volt and so forth until the battery light started blinking and vapor production ceased entirely. Sorry, I should have specified that in my previous post.

And there ya have it, folks. That's probably why I was a little baffled by Arnie's experience.

To hazard an opinion, I'd need to know what VV APV , Battery you are using and what is the Ohms of the Atomizer?

Subohm has nothing to do with mech vs regulated. You are making a point against mech, not subohm.

The answer is because the regulator isn't very good, or perhaps more to the point it is operating at the edges of its abilities. Good regs hold the power steady throughout the operating range.

I was responding to the list Arnie posted where he said that sub-ohm offered more control. I countered that it's probably less control with a mech mod when contrasted with non-sub-ohm and a regulated mod. It's a pros and cons list after all.

Of course, the sub-ohm coils on a regulated mod are theoretically possible with the proper device...but 99.999999 % of the time the sub-ohm people are using mechs.

And yes you can vape high/normal ohms on a mech too. But that wasn't the point. The point was to correct Arnie's "more control" statement specifically made for sub ohm.

Simple. Sub-ohm does not offer more control than non-sub-ohm. And since mechs are used almost exclusively, you could argue that overall there is less control.

Again that has nothing to do with subohm and everything to do with mech vs regulated.

They are not just theoretically possible, they are fairly common and growing more common. But even if there were only 1 example, it would make your statement false since it does not necessarily mean mech.

Well, it is interesting feedback if not made personal, tj.

It's correct that the voltage consistency is an attribute of the power source, not the ohms. However, as a generalization, sub-ohm vaping style is less controlled than the regulated mods MOST are used to. So I wouldn't put "more control" in the sub-ohm pro's list. Of course, he's twisting that fact around to make it sound like I said sub-ohm is responsible for less control.

Also, since it chews through batteries so fast, the effect is more noticeable with sub-ohm because it happens quicker. Note how fast many sub-ohmers are to recharge at 3.7 volts. lol. Whereas many "normal ohm" guys build coils for 3.7 volts and vape for a lot longer on normal ohms down to 3.5 (a generalization, not a rule).

Oh no! no! no! They only run their batteries down to 3.55!! If you take them down to 3.50 you'll halve their life man!! Yee Gahds man, don't you take care of your batteries?
