Aurea mediocritas
I don't like Megan Fox - she looks a bit scary, down in the uncanny valley if you will (face is too symmetric). I digress...
Look what I found
here:
You would look at the mustard line, maybe between that and the purple (we vape at ~2 Amps; these are constant current graphs so they don't fully apply to the mechanical mod
vaping, where we discharge at free voltage / free current so in fact the stated voltages should last a little longer than in the graph)
The point of this is that while it's true that the battery stays around the sweet spot for a relatively long time, the consistency of the vape is definitely affected. But there is a relatively long flat portion of the curve. This doesn't apply to lower capacity batteries so it's less intuitive if you come from an unregulated small e-cig. Those fade out quickly and almost continuously, the larger batteries start very high, flatten out for a while, then start going down. When they say it's not as bad as you'd think, they're right - they're neither misguided nor are they trying to fool you
If you're like me, however, and you think Megan is too hot, then your vape will be unsatisfactory with the fresh battery, then it will hit the sweet spot, then it will go down from there. Not what I have in mind when I explain that
vaping must emulate the consistency of a cigarette in order to best help kick the habit; and not what I have in mind when I want to pick my APV now and have the experience I expect regardless of the charge in my battery.
I love my Reo, for instance - but the best vape with it is if I use up an 18650 in my ProVari for a while, then put it into the Reo until it gets to soft, then either charge it or use the leftovers in the ProVari again.
My point is that while it is possible to get a very good
vaping experience with an unregulated battery as long as the battery is above a certain size,
boosted regulation is
always an added bonus.
I'm lucky enough to have a sweet spot around 7-8 W so the Kick is perfect for me; also, with Genesis-style atties you are supposed to get a better experience for a lower power. If your attachment of choice requires more (see dual-coils), or if your sweet spot is way higher, than you're limited to more powerful devices such as the good variable voltage or the Darwin, but even then there is no argument that there are advantages to a regulated vape.
