Look at PBusardo's reviews of VV/VW mods when he runs tests at different wattage. There's almost always a difference between what a VW outputs and what it should output. .

EXACTLY, Some have speculated that Provari hasn't incorporated VW for that very reason...The technology simply isn't accurate enough(within the price point constraints) for Provari as of yet. Even the dna chip fails, albeit at the low end, during the Variable wattage dance...Just sayin'

Ohms Law is a circle, and there are always three ways to get from point A to Point B.

You got a bad url...either that or ECF has once again decided to change it for you. Not sure why it does that for some url's and not others.

Yes ECF blocked it and I tried three times. It's a cool little Ohms calculator. Copy and paste I guess.... w w w.the ecig stop.com/ecal. html

I have VV and VW. On the VV I turn it up till it does what I want it to. On the VW I turn it up till it does what I want it to.

If I was using RBA I would spend my whole life recoiling rewicking retweaking in search of the promised land but I just have Kanger and Aspire clearos so sadly for me that ridiculous practice of searching for the perfect vape instead of just enjoying vaping is just a dream to me. I can only aspire to that. Ha see what I did there with the aspire thing?

I'm a funny guy. I will laugh to myself at that joke later.

From an operational standpoint it just makes more sense to be able set the power output rather than the voltage input. Now if there's issues with the device's ability to set accurate and precise wattage you might have an argument. But even so, if it were off by a slight bit, it would be just a mater of tweaking it a bit. I think these debates are more often about Provape vs everyone else, than anything else. I also find it hard to believe that Provape couldn't manufacture an accurate and precise VW system at a slightly higher cost.

Ohhhh, that's what this 'debate' is about ; the infamous p word!

Good read man. Very well thought out. To me, VV vs VW is ajust another way of saying the same thing. If I had a VW device, I'd adjust the voltage periodically just as I do my VV devices. It's just another translation of the sweet spot for vapor and taste as far as I see it.

VW is great, but to me (yeah old school vapor as you say) it's a luxury feature. Heck I've used box mods with no voltage display that go from 3.7-7 volts. Just a dial I adjust to taste. So your theory may be spot on.

Something just occured to me: cartos.

Do cartos come in all these resistances? I'm guessing not.

What do you mean? Cartomizers come in a range of resistances. I use them occasionally for my ego's but mainly use them for my gripper I got through madvapes. You can find these all over the place but madvapes ranges from 3 ohms to 1.5 ohms. Them and others also offer dual coal. I think I've seen some as low as 1.2 ohms. Your not going to get subohms...at least not from anywhere that I know of. If you got link please provide...gripper is mech and can handle subohms so I'd be interrested if you know of any that make those pre maid...to my knowledge you need a RBA to get to subohm though.

Cartomizers, Cartomizer, E-Cigarette Cartomizers | MadVapes just an example that cartos come in a range of resistances.

I don't feel like reading through this thread right now so if this has been said before then oh well. Usually VW has half watt steps and VV has 1/10 volt steps. Therefore you get greater variability through VV than VW.
While that's true, it's not really the whole story as the volts are squared.

watts = (volts^2)/ohms

So without doing the math here, voltage is a slightly finer adjustment, but it's not 5:1

I think people don't understand what this is... Voltage is the input. Wattage is the output. A 2ohm coil at 4 volts will give 8 watts power (assuming all variables are exact). It does not matter if it is set by VV at 4 volts or VW at 8 watts... it is the same vape just a different approach to get the desired output. People that say they can't get a good vape by controlling the watts are just fooling themselves and don't understand how their PV works. The only benefit of VW is the ability to set the desired output and be able to attach any atty (assuming you are within amp limits) and get that amount of power output without figuring the voltage input.

    Still seems there is confusion or lack of understanding. I've reread my post several times and not sure how I can improve upon it to help explain the difference. If someone wants to PM me with a modified version of http://www.e-cigarette-forum.com/fo...e-variable-voltage-debate-2.html#post11976426 I'd be glad to edit that post to help clarify. I'm thinking of using that as a copy/paste for when VV vs VW or what is VW comes up as it seems to pop up at least once a month. Please let me know and maybe I'll make my first blog post ;)

    I guess I am a tinkerer.
    I had a box full of juice that tasted bad on fixed batteries and iclear 16s.
    I went straight to VV/VW mods from fixed, I found a range of juice in that box that tasted good all the sudden, all at different settings on the same coils. I do not really care what mode the mod uses or is limited to as long as it is variable. I can do math, VV is VW, VW is VV depends on what side of the equation or mod is working from.
    I now have an embarrassing collection of stuff in a wide variety of resistances and an entire menu of juice options in varying strengths/flavors. I do not want to sit down and do a spreadsheet on what tastes best for me at what setting at a given resistance. 1.5ohms on a Russian is way different from 1.5 ohms on a rewound Kanger coil in a PT2....
    It is way easier for me to throw some juice in something, slap it on the mod, find the setting that works for me and go with it. If it tastes different during the day I can bump it up or down according to taste.

    For me I do not care what it varies by as long as it varies.

    .1 increments in VV is a slightly finer degree of adjustment than .5 increments in VW
    .1 increments in VW is pretty darn cool.

    Nothing is easier than winding my two coils like I always do, slapping them in the dual coil RDA and putting them on a mechanical mod. I know exactly what works best with that and go with it for days.
