VAP I'm new to this
thread and the Vmax, and I got it after getting a Provari, just to let you all know where I'm at.
I have noticed that 3 volts on the Vmax seems to be 4ish volts on the Provari. But from 4-6 volts they seem to agree
(I have the model that resets to 5V)
Have you ironed out why exactly this happening? Is it a simple calibration issue (e.g. the Vmax is "wrong" even though it works just fine after you find where you want to be by taste) ?
Now 1st off as you read this (experienced or un-experienced) I want to stress that
this in NO WAY reflects accurate ANYTHING. This is SIMPLY a
hypothetical scenario in which I'm trying to explain from newb to pro status on a very basic fundamental level just how PWM (Pulse Width Modulation) kinda works in laymen's terms in a very user friendly kinda way without all the big words and terms and/or symbols some people may not understand much less know what they stand for or mean. No duty cycle%.....no mHz%..... simple AVERAGES, thats it. That being said....... let's get started......
Ok, with typical PWM (pulse with modulation) the atty/carto (the COIL) is seeing a pulsation of voltages in miliseconds almost nanoseconds it's that fast. This technique in circuitry aids in battery longevity among many other aspects. Here comes the analogy, now Please keep this in mind, these numbers Im about to
throw out will not make
sense applying ohms law or probably even basic math, AGAIN.....
"this is solely for demonstration and analogy"
Lets keep the voltage on the VMAX at 4 volts. The PWM in "most" units will only allow the coil to see 4V max to the coil but also dipping below 4v down to 3v maybe even 2.5v. The coil sees and is exposed to this range of voltages hypothetically 100 times a second. But the highest voltage the coil will see is the actual voltage that the device is set at (4V in this case)
Now the VMAX, this is where I may lose some folks.... Same situation "4v". Now the VMAX is set at 4v output, on this device they have the PWM setup very different which everyone who owns one now is absolutely lovin it. Where every other device will only see the max voltage set to output(4v) the VMAX allows it to see a much higher voltage, in the V1 VMAX they had the PWM set so that the coil would see the max battery voltage in those miliseconds even at 4v setting. But they adjusted how long and how many times the coil actually was exposed to that high voltage so the AVerage voltage was still showing a very solid 4v with little to NO underload drop with any atty attached. When the batteries have a max voltage combined of 8.4v you can kinda start to imagine now why you don't have to push the VMAX very high at all to get a very nice outcome while saving and expanding your battery life while using lower voltages than normal with a lot less drain and draw on them. Now where the coil was seeing the 8.4v max (whatever the max battery voltage is at the time) in those short miliseconds it also sees down to 2.9v but still getting a voltage average of 4v.
Now the V2 VMAX, FYI, the reason Im able to explain this a bit better is because I've done extremely thorough tests on my LeCroy 312-A 100 mHz Wavejet Oscilloscope which leaves NO stone unturned and is very very sophisticated in how it gets it's "true" readings. Ok the V2.....the V2 uses the same PWM, just fine tuned just a bit. Instead of the coil seeing the Max battery voltage they down tuned it just a bit. Instead of it using the max voltage , now it's about 1.75 volts less than whatever the max battery voltage is. And still dropping down to a 2.9v for the low side of the PWM, and using every voltage at the perfect milisecond for the perfect duration of time at that voltage to still get a 4v average overall.
To my knowledge their is NO OTHER DEVICE that uses PWM the way the VMAX does, until you own one you really can't understand why it's so different and soo powerful. Believe me when I heard Smoktech made a VV device that was supposed to be this "end all" type unit, I wanted nothing more but to get 1 on my equipment and really test it in ways they probably didn't. And I did, over and over, I've put this device thru torture tests. Ending result.... I have 2 now, and every other device I own is in a padded shoebox in my closet, all except my new 14650 Epower for movies and restaurant outings. The VMAX has literally destroyed any and every thought or craving to find the next (better) mod/device. THIS ""IS"" MY DEVICE !!! I don't feel any need to waste another penny on another device, this is it. Im not a collector, and to be honest I never understood collecting mods. One of the main reasons I quit smoking was due to the price increase of tabacco, not spend 3x's as much vaping. But ...to each his own I guess. All in All, I found a device that does EVERYTHING it's suppose to and should do. More importantly...I found a device that does EVERYTHING I WANT AND NEED IT TO DO. I really hope this was able to be understood and everything I typed came out on the screen the way it was in my head...just easier to read. lol If anyone has any questions you can ALWAYS PM me anytime, would be my pleasure to answer any questions or help anyway I can. Take care folks. ................J
