It would mean that the voltage measurements on the Provari are just as approximate as the ones on the Vmax.
That's not necessarily true, and it's one of the problems I have with pbusardo's reviews: he's awesome, funny, very experienced, and very smart……but he'd not great at math. Vav isn't necessarily what matters with PWM depending on
exactly how the device works. Vrms would be better.
Because of the timings involved, it seems like power delivered is what's important. And a coil doesn't care which direction the current flows inside it (you can put a battery into a mechanical mod backwards and never notice……as long as they're not stacked batteries facing opposite directions). Vav counts the negative voltages
against what the coil is actually getting…Vrms counts it the way it should. So, basically, none of his numbers are accurate for PWM devices.
I have no idea what purpose PWM would serve on a boost mod but, the Provari is using it.
The same as on something that steps down voltage. By creating a square wave with a DC offset (so it goes higher on the +V side than the -V side, for example) you can alter power output by changing the "duty cycle" (or when in the cycle V is > 0). Stepping up vs. stepping down is a matter of circuitry.
But, if you can get 120V AC (sine wave) off a 12V DC car cigarette lighter plug……I think getting a ~10Vpp (peak to peak) square wave with a DC offset off a 3.7 V battery is no big deal.
Here's a few (hopefully subjective) points to consider:
Awesome post.
If you're an average vaper, all you need is a way to get the voltage to a point where the atty/carto/clearo + juice combination tastes best and produces adequate vapor for you. For ease of use, the Twist stands out because you can easily just tweak the dial a little in one direction or another and vape to find that sweet spot.
Agreed. Wholeheartedly. That's why the Provari doesn't appeal to me. I would
never be happy using that button. Frankly, I don't understand why anyone puts up with it. I'm sure it's an awesome vape, but I think it's a
horrible design made by someone who has no idea what user experience is. Obviously people disagree with me there. But the Provari only fits into my "toolbox" as well as a kick in any mod that can accept it and is only marginally better than any 3.7V mod.
I would have been find with a Twist, but I didn't know that at the time.
The funny thing is that I feel very similar about my Twist. I'm interested in a lot of stuff because I'm kind of just a gear ..... in every hobby I have. But where I'm running the Twist, I know I can be
okay with low-res stuff & a 3.7V mod. And I have a VV device available if something shows up out of spec. I'm
way more likely to buy a provape-1 than a provari……and I probably will because it seems to give you the build quality and the gorgeous aesthetics without the BS interface. If I had a provari, It'd end up getting set and never changed……probably right at 3.7-4.0, which you can get by just swapping batteries when it gets too cold.
