I love my MVP 2's but If I was looking for a tube mod, I'd go with the Provari, even though I love Innokin product. If I had to give up the form factor, charging convenience, and USB passthrough of the MVP2 and go to a removable battery option, I'm just going to go "all the way" and get the ProVari.
However what really irks me is people who dismiss variable wattage and say that variable wattage is a marketing ploy, or try to equate variable voltage with variable wattage by saying...Hey, the Provari is variable wattage, I vary the volltage and that varies the wattage at the coil.
When you say things like that, you are either ignorant of how VW works, or you are just being contrary.
If you are using an RDA and building your own coils, then variable wattage brings nothing to the table. You are using a single atty to drip your juices, you don't change atty's often and once you re-coil, you set to your desired voltage and you are good to go. Variable Wattage doesn't provide you with any benefit.
However, I have 4 mini protanks filled with four different flavors. I vape at 7.0 watts. I've tried diffferent settings, but 7.0 watts is the sweet spot for all my juices and Mini PT's.
When I swap my tanks, my atty resistance varies from 2.6 to 2.9 ohms. If I had vv only, each time I put on a new tank, I would have to readjust. With Variable Wattage, I don't. That is not a "marketing ploy". That is fact. My MVP 2 is set at 7 watts and it has been set that way for three weeks. No adjustment necessary.
I actually was seriously thinking of getting a Provari before I bought my second MVP2. It was Christmas after all. So, I decided to go exclusively VV for a weekend just to see what the experience would be. I read on these boards that VW was just a marketing gimmick and you didin't need it....blah...blah...blah...
Every time I swapped tanks, had to change my voltage. Otherwise, one tank would be fine, one tank would be weaker, and the next tank would give me a burnt taste. It didn't take much adjustment, but I had to none the less. It was annoying.
Don't tell me there is "no difference between VV and VW"
If you are a tweaker, or run the same atty, then no, there may be no advantage of VW over VV. But your personal vaping pattern does not make VW a marketing ploy.
