The ProVari actually DOES use PWM to vary its voltage output. Someone recently posted a comparison between the outputs of a ProVari and a Vamo (see http://www.e-cigarette-forum.com/fo...ari-oscope-vs-vamo.html?highlight=provari+pwm ) including putting them on an oscilliscope. The difference (and the reason so many people like the ProVari so much) is that while most devices run at a slow rate (37Hz, or 37 on/off cycles per second), the ProVari does it at 800Hz (800 on/off cycles per second) which results in a much smoother power feed to the atomizer.
Just wanted to clear that up![]()
wow thanks for the info Hambone. i was told differently originally. bottom line is: one can tell the difference in vape between the two types of PWM.
Lahme- Vamo is a great PV for the price. i own one. its no provari, but that doesnt mean its not a great PV.
