After using the 33.3 mods for a while, and just recently purchasing a ProVari, I have noticed something. The hit is much smoother than the 33.3 mods that I have been using. I get a GREAT hit from the ProVari, but it does not give me that "have to cough" sensation. I thought maybe it was just me at first, so I tested it on my daughter. She always coughs when I ask her to try one of my mods. I asked her to take a hit off of my ProVari, and she did not cough. She said it was a much smoother hit, and actually took another even bigger hit.

I have been watching some vid's on the subject and noticed that these 33.3 mods are pulsing about a 6 volt signal at about 33 hz, and keeping the signal on for different lengths of time to imulate different voltages. It looks like the ProVari uses a much higher frequency (i think 800 to 900 hz), and in addition, regulates the output to the actual voltage setting, and not a 6 volt pulsed signal.

Is this the reason for the more consistant, and smoother hit on the ProVari?

Or am I totally off base with this?

Just wondering.

I am far from an expert on this but you came to the same conclusion as me. I don't have a provari but I defiantly noticed the smoother vape moving from a Vamo to a mech with a evolve kick and kick 2, which also have a much smoother output. I also noticed that my vamo was much smoother with higher resistance coils, I think they handled the 6V spikes much better. While most of these 33.3 mods are a great value I now know they are not for me. I also noticed that my coils seem to last much longer before getting gunked up with the smoother output, but i am not totally sure that isn't just in my head yet.

This has been a controversial subject on this forum for some time now. I've noticed the difference between the 33.3 hz chip (rattlesnake frequency) and the 800+ hz chip of the Provari. Many new owners of a Provari have noticed it too based on comments in the Provari sub-forum. Of course, there are those detractors who claim that they can not tell the difference (mostly non-Provari owners), but the majority of people who get to use a Provari over a period of time will be able to if they also have a mod which has the 33.3 hz chip to compare side by side.

Along with the Provari, the iTaste MVP and iTaste V3.0 also use a higher PWM signal, and also have the "smoother" vape.

Great information.

Thank you for sharing.
