Are they selling an adjustable one again? The one I got from ProVape a couple months back is not adjustable. It doesn't have that small slot in the post to insert a small screwdriver.

Its doesnt need the screwdriver slot to be adjusted . Just take a razor blade or anything thin and just pry it up a little.
Your not gonna find a IC like the provari unless you build one and program/code it yourself.
You could get the evolv dna if you want vw

Unless you made a mistake in your post - you've got it wrong. The Provari isn't variable wattage it's variable voltage.
I suspect it works out the same in the end, since by varying the voltage you are in effect varying the wattage also (assuming the carto resistance remains constant.)
that screwdriver slot was for airflow I guess, you can turn it till the cows come home and the post does not actually move, theres no thread in there.
perhaps just the act of putting a screwdriver in it and turning it moves it by pushing it in the silicon insulator.
Not the same at all... Here the thing, an attys resistance will change with usage.. Im using an HH357 custom, when it was new it read at 2.5-2.6 ohms.. After about 10 days of use on my Provari it reads at 1.9 ohms so I manualy turned down the voltage so I could stay in the 10 watt vape area.. Now with a VW mod or Kicked VW it will self adjust to keep a constant that it was set at... Thats the plus I like better about VW, you set it and forget it... With the VV Provari I am needing to check my attys resistance to keep things constant........
Ah, I see what you're saying. That makes sense. Thanks for pointing that out to me, Riverboat!
Does the provari use PWM..?
I can see that it is referred in the FAQ. I thought it was not... that the voltage was steady to the one set and not of pulse waveform ...

no PWM in sight, its a very rock solid linear output.
it does use PWM to the internal switching regulator of course, thats how a switch mode works, but then the inductor magnetics and output filtering boost and clean it up.

It is Pwm'ed but like said above you would not see it on the output of a scope becacuse its cleaned up before the output.
it is NOT pwm, pwm implies the switched voltage is applied to the load directly, the filtering being performed by the load itself.
it is not being simply 'cleaned up' .. thats implying a simple RC filter. you are completely ignoring the magnetics for energy storage providing the boost.
You can oversimplify things too much, yes they both use a switching device used saturated to gain efficiency, the basic form of regulation is then a variable duty cycle waveform.
but to me its like saying a motorbike is the same as a car as they both have wheels and in a technical discussion is just wrong.

so i bought a provari v2 during their "blemished" chrome sale. i love it. i also bought 2 batteries and their tenergy charger. i notice that my battery only last about 4-5 hours of vaping. and im not really chain vaping either. before i notice the red starts up blinking. how long does an average battery last? i just have he 18490 red imr ones they sell on provape. did i get a dud provari?? supposedly all the internals r brand new and under warranty. i just want to know before i contact them for repair.
I turn my lt off on my varis so as no premature blinking usualy untill it is done,try when it starts blinking unscrew bottom cap untill not blinking then screw back on you might have more life left.
4-5 hours of vaping is no measure; it depends how many discharges of the batt no?
You can measure by time but it depends on how much you vape during that time.
A better measure is how much juice you go through.
Actually, if I vape hard for a few hours; say 3mil of juice, that's all a 18490 will put out.
Go with the 18650, and get a few batteries, a good charger and keep a couple per day.
I have a Pila charger and go through 2 18650's a day if I vape all day and evening.

From the horse's mouth regarding PWM:
PWM can be implemented in a couple of different forms. The main reason for using PWM is to switch MOSFETs (Metal Oxide Field Effect Transistors) on and off in a digital manner to keep the voltage drop and thus power loss as low as possible. This keeps the total converter efficiency high. In our case when the MOSFET very quickly switches the current off to the main converter inductor it transfers its stored charge to an output capacitor bank. The capacitor bank thus switches the PWM switched current to a constant output dc voltage. This output voltage is monitored in a feedback loop to very accurately control the energy to the atty. If the output was not converted to a dc voltage it would be very hard to monitor the output power in a feedback control loop. The output would be a duty cycle on/off waveform that is difficult to control.
We recommend you look at some of the standard power converter text books. The block diagrams for different forms of PWM converters are discussed.
The Provari is measured to run close to 95% efficiency.
Enjoy it.

I have IMR 18500 flat top batteries that are from nhaler and are charged to 4.19v. I just got a ProVari in a trade and it's not turning on. WTF is going on. Does this thing only work with button tops??? PLEASE HELP!!!
