    ALL modern VV and VW devices use PWM as a means to give us variable voltage/wattage, but not all of them have a pulsed output.
    Radar nice to see you again.
    You forgot to mention that while they are all using the PWM . some have filters that even out the voltage which is why the line is flat.

    Hi Jimbill could you look at my post, I didn't say necessarily that the Vamos Vape is inferior to a Provari, I said it's different. Taste is subjective, some will prefer the rattlesnake and some not.

    The purpose was to point out that the PWM Mods without good filters, scientifically are different then the ones with filters.

    It's the preference of the user, which is better, or if it can even be detected. But it's inarguable that the devices are not the same.

    You could call it a matter of semantics. There were references to "PWM mode" and that some mods were "not using PWM". Those statements on their own are misleading as all stated devices use PWM in some fashion. Whether the mod has a square wave output or a low ripple DC output will depend on the fashion in which PWM is used.

    Innokin may seem like a cheapo, but they make a quality product in the MVP 2, and VV-3. Yes they are throw away mods, but they are built like a long lasting mod sold for much more.

    Might as call all devices "digital," because they have a binary on/off switch.

    Most of the regulated mods fire at 33.3 hz. Some people can't hear this effect, some can. Just because YOU can't doesn't mean others can't too.

    The Provari uses 800 hz as its cycle, and reportedly uses higher quality filters. Provari owners often remark about how the Provari's vape is "smoother". I have noticed this myself when compared to my other regulated mods. When I received my MVP, I was intrigued by its smoother vape, too. It wasn't until just recently that I have learned that it has a similar PWM as the Provari. Now it makes sense.

    Again, not everyone will notice the difference, but many can. Don't judge those who say they can tell the difference.

    There's a name for that.

    Thank you for this open discussion. I have been using ego c twist & I have been vaping for 6 months yet not liking flavors. I still smoke my hand rolled cigs to. I have been trying to figure out what APV to buy.

    I can definitely notice the rattlesnake effect on the Vamo versus the Provari. It doesn't bother me too much, but I prefer the higher PWM. What's the cycle rate of the MVP? Maybe someone said earlier and I missed it.

    What about the SVD? I've been pondering getting one of those. Since I got the MVP, I may not get one, but I'm still curious.

    Typical hater response. There's one in every thread when a Provari is mentioned.
