    Variable voltage or variable wattage, the end result is variable heat at the atomizer coil. If the electronics in your mod control wattage, then you can change atomizer resistance and the vape quality will be the same until you turn up the wattage. With a variable voltage mod, you will need to change the voltage for different resistances in atomizers. A 2 ohm carto will need 3.7v to produce the same vapor as a 3 ohm carto at 4.2v. Wattage regulation is probably easier to deal with, but it's a different concept for those of us who are used to regulating the voltage with which we vape.

    Variable voltage operation is similar to the volume control on a radio. You set it for personal preference and leave it for the most part. If you move it to a new room with different acoustic qualities, you need to reset the volume control. If the radio had the ability to control the decibel level by itself, you might could set it to a decibel level and forget it. Most of us like fiddling with the controls to produce the "perfect" setting. :)

    Hi Vpman,
    it isn't really about one or the other between pvs anymore :) The mods out now have both variable voltage and variable wattage. So you can use both on the same mod.

    Variable voltage means you can change the voltage on your pv. When you do this you need to make sure the resistance (ohms) of your carto, atty, clearo etc is matched within a range so you don't under power your vape or over power and end up frying something by the amount of watts you go to.

    Variable wattage has been around for quite a while now. The Darwin is a variable wattage mod. However they are virtually impossible to get. A lot of vapers added variable wattage to their pvs by using the Kick - a small piece of circuitry that can be put on top of a battery.

    The latest variable wattage devices have variable wattage incorporated into the pv. You can set the watts (power) and the pv will automatically adjust the voltage for the resistance (ohms). You don't have to calculate using ohms law.

    The newer variable wattage devices also have variable voltage - so you can use either on the same pv. Variable wattage is more convenient. You can change from a cartomizer to a clearomizer, or a tank while vaping, and stay at the same watts, or adjust the watts - and not have to calcluate whether your volts are ok for the ohms of your clearo, carto, or tank. The voltage is automatically adjusted for you. It's less hassle to find the right spot and stay on it. A lot of people prefer variable wattage now.

    If you're interested in trying a mod with variable voltage and variable wattage then the Vamo is a good one to pick up - inexpensive and works well.

    Good call kiwivap

    Remember with this VAMO that you can only have this in one mode at a time VV or VW

    Also lets say that you like vaping at a 1.3 ohm Dual Coil Cartomizer tank at a higher than recommended voltage. In the VV mode you can get that, you can not in the VW. VW basicly recognizes the ohms and set its self to the proper voltage. VW is nice if you are switching ohms all day and cant be

    Bah. One (VV) makes you think about it a bit, or even do some division and multiplication if you want to, and select a starting voltage and adjust from there. The other (VW) calculates it for you, but because results/coils vary you have to adjust it anyway.

    So...meh. Start low and adjust up. You adjust it until you like it. If they invent a psychic PV that KNOWS how you liked the vape and auto adjusts, I'd be impressed. I was going to put one out that just had a color gradient, cool to warm, rather than all this digital readout stuff so people would just "turn the dial up or down and shut up."

    The interesting thing is having an ohms readout for the atty/carto/tank/whatever.

    Very well done AttyPops. I've got both VV and VW devices. I stilll have to adjust both depending on juice, resistance, mood I'm in, ETC.

    All variable wattage models out in the wild right now are, also variable voltage devices. The same can not be said in the reverse.

    I would recommend a variable power mod, assuming all other aesthetics are the same.

    Some people enjoy the consistent performance of variable power, whether they use a 3ohm, 2.3ohm, 2.8ohm, etc the power given to the coil is automatically set, no fiddling.

    Essentially this "ease of use" and consistent performance is the main draw of a variable power device.

    If you like fiddling with your settings often, even at different times using the same carto, both VV and VP will be handy.

    Perfect thread replies to my question I put on another new post. Thanks to all the Vets. My SIGELEI is getting a workout. Battery power drainer though. Using a Genesis style mostly, but a T3 and ViVi Nova are giving me some great vapes too. Now I just need to get my hands on a mechanical mod and really "Bring the FOG"

    It all depends on how you vape.

    I look for Provape to extend VW to the Provari. When they do, I expect to be able to send mine in for an electronics upgrade. V1 to V2 was done for around $24.95 plus shipping one way to them. They paid to return it.

    Think of VV and VW in similarity to speedometers that read KPH and MPH. Both are different ways of reading the same speeds in another way. Whatever you feel comfortable with is the important thing. Most of us have a favorite setting for different coils and juices. You turn it up and down to find the sweet spot and there it stays. Yes, VW lets you set the wattage (heat) once for any resistance, but you will still have to play with it to find satisfaction on the new atomizer. When you change cartos, chances are you will play with it again.

    It's still no more than a volume control on a radio. We all have our favorite settings for the car stereo. My wife says my preferences are too loud. When she tries my PV, it's also too strong for her. ;)

    Before vv, a lot of vapers would calculate their preferred wattage by voltage squared divided by resistance and purchased atomizers accordingly.Of course, most attys had/have a + / - .2 ohm variation (sometimes more) of stated resistance. A multimeter was a good tool to get the vape you were after. Now it doesn't matter if you have variable voltage, you can adjust to the resistance variation with a button push or two. The mods available today are the manufacturer's response to the wants of the vaping community. In other words, how you go about calculating your preferred wattage is up to you. You can stack batteries on a mechanical mod and use high resistance coils,low resistance coils, single battery, regulated, unregulated,vw/vv, it really doesn't matter.
    Todays vw mods just take out the need to do the math with a quick scroll to and selection of a menu option.

    You change resistance in the atomizer, not in the battery. You can buy different resistance atomizers to use which is why people are liking VW so much right now. Just put a new atty on and go, it's set the same as it was before. Or you can start on rebuildables and it will stay set where you like it.
    I don't change much, but my tastes and mood do, I like being able to turn it up and down as I desire, others don't like to do that.
    I'd hold off on the Evic right now. It's a great concept, but really seems to need some work from the reviews I've seen of it. It's a week out and already on the second revision of the firmware and there have been a few reported problems, with the first batch already. I think with some time it will be a great unit.

    Yes, the wick has a coil wrapped around it that creates the resistance that creates the heat that creates the vapor.
    As to the last part of the question, Yeah? Taste is so subjective it can't be nailed down really. Some juices taste better at high wattage, other mute out. Some people like a warmer vape, some like a cooler vape. Some like this, some like that, it's hard to say what will work best for you. The general rule of thumb is take the resistance and add 2 to get the voltage. At 6v theory would say a 4 ohm carto. BUT put it in a tank and it might not be warm enough with the cooling effect of the juice outside the carto.
    So, Yeah? Where do you like it? This is the great joy of VV and VW, you can adjust to what you like with what you have, instead of buying a new carto to match what you have.

    I've not tried the Joytech Evic. I went through a Joytech 510 and all the variations available for eGo before buying a Provari. I haven't been tempted to try anything else since. I spent most of my time vaping the eGo and used the tanks before finally settling down with Boge cartos. I've continued the carto routine with the Provari, although I will occasionally use a Smoktek DCT tank.

    The best way to get a feel for a particular ecig brand and model is through the search feature at the top of the page. You will find endless discussions on whatever you need to know about.

    Do not think too much and do not spend a lot of money for search - just buy ProVari. It is way with less spending.

    I would say don't "just buy" any pv. Do some research and find out about it. That's why people post the info here - to assist people in finding out about pvs.

    VW it is going by the watts you set. It isn't just matching volts to ohms - its adjusting volts by the watts set and the ohms of the attachment. So you can go higher than recommended voltage in watts mode. Ohms law still applies. But with normal vaping you aren't going to go so high it's blowing things out, and you can change from one resistance to another while staying at the same watts - the pv adjusts the volts up or down.

    Yeah, but VW needs settings for #-of-coils. DC stuffis uses double watts, for example.

    I don't know why anyone would want to use 1.3 ohm dual coils with these pvs. They usually cut off at 1.2 ohms and may read a DC as a single 1.3 ohm. Considering the power capacity of the pv LR isn't needed anyway.
