Interesting information fuzzione, hadn't thought of that before. Have wondered from time to time why people would buy 6+volt units to vape higher ohm vaporizers and now I guess I know. :)

Thanks for that bit of clarification.

Here's another response that I received from the thread I originally posted my question on regarding low vs high ohm vaping.

By Dusty_D http://www.e-cigarette-forum.com/fo...vv-device-battery-recharging.html#post6016195

"Here's the difference..Ohms Law.

Simulating 9Watts overall output.

3.7v set on device. 1.5ohm atty. Output is 9.1W. Power used = 2.45 Amps
5.0v set on device. 2.8ohm atty. Output is 8.9W Power used = 1.78 Amps


The difference in battery longevity is in the amount of Amps that your battery is putting out to produce the end result. Higher Amps, less life. Lower Amps, longer life. Lower Amps also means less HEAT being created causing the flavour to subtly change, if you vape a flavour that subtly changes when vaped at different levels.

There is a difference, however subtle between vaping low ohm/low voltage and high ohm/high voltage
"

Figured this might be helpful to some on this thread, I found it so. I'll be buying some low ohm cartos to experiment a little. It seems the amps produced also bear some relevance to the vape experienced despite identical wattage.

Just wondering if PBusardo got one of the 1st batch units with the voltage/button problems. In his recent review it seems he may have encountered both issues.

As have I. Bad button, non function auto shutoff. Yanked the batts but could smell a burnt chip or something.
AllAboutVapor corrected the issue with a quickness. Good service over there. Really good, like shipping conformation & tracking email within 2 hours good.
I have noticed that you turn it down compared with other vv's. On LR's start at 3v, it's not a joke.
It has the pulse power from hell. Whole new ballgame in sweet spot finding. I love my black dragon.

I have to question that a little. I think what is being ignored is if it actually IS the identical wattage. Too many PVs have different voltage drops with different resistance coils. So, if you're trying to match wattage by calculating the resistances of your coil and switching attys, you're not really comparing apples to apples in terms of wattage.

I suspect that if you did the same experiment on a device known to maintain a solid and predictable loaded voltage regardless of what resistance you used, you'd be hard pressed to notice a different vape with the same calculated wattage, despite the difference in current. If I did notice a difference, I'd be more likely to attribute it to the physical differences in the coil, exposure to juice or some similar factor.

I see. Well then this puts me back to where I started from...thinking there likely is no advantage to low ohm/volt vaping when one can simply reproduce the same wattage using higher ohms and volts on a vv device. If true, the latter appears to represent the more sensible approach, in that the lower amperage seems to be easier on batteries.

If anyone else out there has expertise in this area please feel free to chime in; I'm really trying to understand whether such distinctions have any practical effect or if this is largely an academic question. I did not anticipate such diverse opinions on what I initially believed was a straighforward noob question.

It seems like the VMax has strong power values; it vapes like a beast, and though different from a Provari VV in that sense, and in a good way, how does it compare in other ways?
Like Fit and Feel.... does is function easily, how does it match up with the quality "feel" of a Provari?
The "F's"... fit, feel, form, function

I think the VMax is just great in all of those "F"'s, but if I really did want one of the two to stop a bullet for me, it would be the ProVari.. Thicker tube walls (not that the VMax is "too thin"), and the empty body weighs 2.4 ozs (I think?) to the ProVari's 4 ounces. As Phil said, I think it's very nicely built.

Am I seriously the only one getting "sorry clip not found" with the "I’M AWARE THIS VIDEO IS NOT WORKING RIGHT NOW. I’M WORKING TO GET IT BACK ONLINE" disclaimer at the top of the page?

BP, I now feel your pain. That is exactly where I watched the video this morning, and now I get the "clip not found".

I blame the ProVari fanboys. They must have hacked into both YouTube, and PBusardo's website.

(Or not). :)

And John D ...... I found you a scope for $84 bucks, I'll PM you the link in the morning. I didn't forget about ya.....just had to be reminded....lol :p
The heck with him. PM it to me. 40 years ago I used to be able to operate those big Tectronics ones on a cart with tubes in them... maybe I can turn this one on.

I suspect you're probably right. Low res. coils are an attempt to squeeze maximum wattage from low voltage devices. I'm not aware of any other advantage to their use.

First, props to sailorman for so aptly pointing out that the watts you think you're getting based on numbers arrived at by one's able assistant, "Rosie Scenario", on her handy-dandy calculator usually aren't going to be the watts that you're actually getting to your coils. For example, a 3.7-volt device that is regulated to 3.7 volts is not going to be putting 3.7 volts to the coils most (any?)of the time; and none of the time when the battery is below 3.7 volts. Enter; a good VV device that you can adjust to find your sweet spot on any given juice/attachment. (Have I told you about my VMax? lol And let me show you some pictures of my grandkids, too. The cutest kids who ever lived. LOLOL)

J/K of course, any good VV device will let you get a top-drawer vape when matched to an appropriate "set of works". (The VMax will just do it better than any other device on the planet (AAAARGGGHHHH .... wrestles with own leather-gloved hand!!!) (Please see ):

Dr. Strangelove talks to the War Room - YouTube [2:00-3:30] "We must not have a mine shaft gap!" LMAO @ Peter Sellers :)

Ok then: Regarding "If anyone else out there has expertise in this area please feel free to chime in; I'm really trying to understand whether such distinctions have any practical effect or if this is largely an academic question" .....

I will soon have some experience with this as soon as I get some 3.0, 4.0. 4.5, and 5.0 ohm single coils cartos and a crap-load more DCT tanks so I can put my VV APV through its paces and find out for myself what, if any, the advantages might be to HV/HR vs. LV/LR. Theoretically, I think it might have to do with the total area of coils, higher-ohm coils having more, assuming wire of equal resistance per unit of length as a lower-ohm one; "it" being a possible improvement in/optimization of PBusardo's "VTF" - vapor (amount of), throat hit, and flavor. And as "noob" questions go, yours is about the best one I've ever seen.

VAP just emailed me a boatload of info, and then asked me to forward it to you, which I will do right now.

And is that "Mr. Natural"?? Love that dood. :)

I just finished watching Pbusardo's review of the Vmax. It finally showed for me at Taste Your Juice.

Great review, as usual with Phil but why spend so much time with a 2.2 LR carto on this review? If I wanted to spend bucks on on a VV I'd want to know how it handles SR and especially DCC? I'd feel a bit silly spending the money for a Provari or VMax and then using it for LR cartos that I can run on my E-Power 14650 for a fraction of the cost.

Again, totally agree, as is evident from my post #502.

To repeat part of it:

"Before I comment on his review, which I just about 95% agree with (I think the button is just fine), I just want to throw out there that I agree completely with VAP (as usual) about the LR atty with VV thing, especially one like the VMax that appears to be a little bit on the sizzlin' side. Why would you want to use LR attys on a very powerful device? (???) Isn't that a little like running 235/30/20's on a 'Vette? Yes, you can do it - but why? (??). Can't run the same tanks/cartos/whatevers on your VMax as you do on your other PV's? Then spend the big bucks on a few more tanks/cartos/whatevers that you use just with the VMax".

Big ohms + big volts + ideal wattage on a single coil + low amps + great juice = superior vaping experience? Certainly looking forward to finding out, and will obviously report back.

I have seen suggestions that SR on a VV will tax the batt less, and possibly help the atty last longer too?

LOL...good luck with all that; I'm genuinely interested in learning of such results. Although, sadly, I suspect you will find that with a vmax in hand....resistance is futile.
