I have several VV devices in my arsenal... I love VV... for what it's worth. I have A ProVari, A Lava Tube, An Infinity and an Infinity Pro. I also have a rather cumbersome and oversized Prototype of a VV Zenesis that will never be released, because I don't want to deal with being an electronics manufacturer when there are plenty of VV PVs on the market.
But you don't "need" VV for a Mesh/coil atty. You may want it... You can even benefit from it... but need?
I don't agree that there is "need" involved.
The biggest benefit of VV, as far as I'm concerned is Voltage regulation... I set it at 3.6v - 3.8v and it stays there... that's nice.
But an IMR battery without a VV circuit has a pretty smooth power curve, spending most of it's charge life ABOVE 3.6v... when the vape feels a little weak, I change the battery... That's after about 8 hours of vaping like my life depended on it... problem solved.
I've been working with Mesh/coil attys for quite a while... I've done a TON of experimenting. I don't claim to know everything, but I know a lot!
I have watched countless threads where folks have issues getting their atty to perform properly. But do you know what I've noticed? The people that have the hardest time getting them to work are experienced vapers... Newbs follow instructions... If they get it wrong, they read the instructions again. If that still doesn't work, they ask for help. No problem, but usually they get it right.
When a newb has trouble getting a device to work properly, they blame themselves and correct the problem... if a Maven vaper finds something to be difficult or problematic, they blame the device and dive head first into fixing what they perceive as design flaws. If you have been vaping 2 or more years (even a little less), you remember Pyramid Tea Bags, Blue Foam, Fluval... what a headache... but eCigs required tweaking back then... a lot of it! Then along came the carto... I remember the raised eyebrows... HUH? What's this? How do I tweak it? Ummm... I can't make it work! It tastes funny... how do I fill it? OH, and remember the taryn spin?
How fun!
When I first took the Zenesis to Vapercon in Richmond... I remember the questions... "Can I put 2 Cr123a Batteries in it?" "Can I use my NiMh 4.8v battery?"
The answer is YES... You CAN...
But here's why you shouldn't...
Watts are watts... I'm not going to break out with the math here... it's old news.
Trust me... We are working with the "LAWS" of physics here... not the "General guidelines" of physics or even the "Really Good Suggestions" of physics...
LAWS...
And it's always the Mavens that want to vape at higher voltages because THEY HAVE EXPERIENCED THE BENEFIT of doing so, with HR Attys and Cartos... And they KNOW how to get a consistent vape at those voltages, and more importantly, with the cartos and attys they are using it requires that kind of voltage to get that satisfying vape...
I'm going to repeat something important here...
"with the cartos and attys they are using it requires that kind of voltage to get that satisfying vape... "
But with a Mesh/coil atty, no such issue exists. In fact, twice as many wraps to get to higher resistance, thus higher voltage INCREASES the chance of having a shorted coil... More wraps = greater opportunity for failure.
More wraps costs more...
More wraps increases the liklihood that the juice will burn off the wick more rapidly, thus increasing wicking problems!
So back to VV... the regulation aspects are good, and useful... not needed, but good and useful. The higher voltages attainable with VV are not needed at all. The lower voltages for fine tuning are nice... but needed? Nah.
BUT...
If you HAVE a VV device and you want to be able to get into these attys without having to buy a whole new PV... The Z-atty line is there... and they are designed to fit specific PVs because I am an OCD idiot that hates unsightly gaps... The Provari is a Nice PV... The ScubaGen atty/tank is cool looking... Put one on top of the other... That's some goofy looking stuff...
I always say "Vape Proud"... but hey, Some Times it's hard to vape proud when your gear looks like you stole it off the set of Mystery Science Theater 3000
