What variable voltage/wattage mod to get?!

[WhiteKnite]

I have the itaste vv 3.0. it is vv/vw although i dont think it can do both settings at once, but i am really enjoying it. I just got a Kanger protank 2 for it the other day and it works awesome with it. dont think you can go wrong with the itaste vv 3.0

You can't have VV and VW at the same time because with a fixed resistance (your coil will always be a constant ohm rating) wattage is just the voltage squared and divided by resistance. The only advantage to VW is you can automatically apply the same current to different resistance coils without doing any measurements or math.

I have an SVD and Protank 2 on the way. The reviews seem very favorable.

disposable?

The MVP2 is disposable in that once the internal battery fails to hold a charge, the device must be thrown away.

On other "mods" they use a user replaceable battery.

One of the biggest criticism of the MVP2 is that it is "disposable". Now how long wiill that be? Well if the unit lasts for 300 full discharge cycle charges, and you charge it once every 2 days, you are looking at 600 days. That's over 1.5 years. And realize that after 300 full discharge cycles, your capacity drop is only about 20%. Add 20% (10% per year) for the natural loss of capacity of all LiIon batteries, and you are looking at after 2 years the MVP2 having only a 1300mAh capacity instead of 2600mAh.

If you are looking at getting a new mod after a couple of years, then I have to agree with every one in saying it is the best bang for your buck. I think it is perfect as a primary or backup vape device, because I think there is nothing better at it's price point.

If you want to keep something longer than 2 years, then I think a ProVari (despite the lack of EDIT: Variable Wattage) is pretty much your best bet. However, there is a strong case for the Sigelei V3 or V5. There have been reports of loose circuit boards on these. They seem to be well built and well performing.

Oh, for heaven's sake. If you want the best value VV/VW tube mod buy a Sigelie Zmax Telescopic V3 or V5. If you want the best VV tube mod buy a Provari. If you want best bang for the buck disposable buy a MVP2. 'Nuf said.

This about sums it up.

I am new so please bare with me but I am reading here in your post and in others that state the Provari is not a VV (variable voltage) and I did a search and found a Provari on a site called ProVape that has a variable voltage Provari. Am I misunderstanding something here? Appreciate the help with educating a newby!

Sorry, it is variable voltage, it does not have variable wattage. That means you can only control the voltage of the battery. On a variable wattage battery you can set desired wattage and the device will automatically determine how much voltage to apply based on the resistance of the coil.

The easiest way to compare variable voltage and variable wattage is to think of a car.

Variable wattage is kind of like cruise control. If I set a variable wattage device, then the device will try to maintain the same wattage, just as a cruise control will try to maintain a constant speed regardless of road conditions.

Variable voltage is like an accelerator. I can still maintain speed, but when road conditions change, I have to compensate. In a variable voltage device, when the resistance of the coil changes, I have to adjust voltage to compensate.

Some like variable wattage, some like variable voltage. It's a matter of preference. If you are used to adjusting your device for flavor, then either one will do you just fine.

However, if you, like me, vape similar tanks and similar juices, then variable wattage allows you to set a set power and when you swap out tanks, the device will automatically compensate to give you a very similar vape experience.

My advice is go mechanical, I just did, and it's way better! i have yet to try a ProVari, that might approximate the smooth of the mech.....

All the others fire on and off like little jakrabbits, hot and cold real fast, 33 ties a minute...

When I tasted this mech mod with dripper head, mwow nver going back, selling my VV's

Provari's, MVP's and VV3's just to a mention a few do not use 33 hz chipsets and fire flat on the output.

Understood, thank you very much for taking the time to explain that. I currently have a variable voltage and I love it. Its a Halo Triton and I have no complaints but I really like the features of the Provari. Am I allowed to ask for the best place to purchase the Provari. I suppose I could find a forum here that touches on that. Thanks aging for the info.

So what does that mean? The not using 33 hz and firing flat in responding to his mechanical advice. I honestly do not know what any of it means, lol. I am just learning and again I suppose I could spend hours trying to find it here but if you don't mind explaining I would appreciate it. I am just wanting to learn what the best device for my use is. I find I switch a lot between big tank, mini tank, cartos etc. so this is why I like the VV. But if there is a better more enjoyable way of vaping I am all for it. Appreciate the help!

 

[zanedog]

I just got onto a mechanical mod kick. I'll sell you a VTR, Coolfire 2 or an eKross.

I will never buy variable voltage or wattage again, just my opinion.

Might try ProVari, matter of fact, gonna try to source them now lol....

The poster was talking about how most mod's vary their voltage. He mentioned "jackrabbit...hot and cold real fast, 33 times per second".

This was a reference on how many mods regulate voltage at the coil by using pulse width modulation. Basically the mod applies a higher voltage (usually 6 volts) to the coil and then varies how long the unit applies this higher voltage to the coil to reach an "average" voltage that approaches the set voltage on the device. Most devices do this at 33hz. so you can actually hear and see the pulse on a scope.

So if I set the device to 6 volts, then the device would just show a flat line of 6 volts. If I set it to 4 volts, then you would see it fire at 6 volts for a bit, then turn off for a bit.....

You can see this on several of pbusardo's videos of Vamo's, Sigelei's and other devices. ProVari's, MVP's and VV3's do not output a square wave form. They output a flat line at the set voltage.

Some claim that this allows the vaper to have a smoother vape.

 

[yzer]

The 33.3 mHz chips will produce an audible sound called the "Rattlesnake" when vaped on certain atomizers. I hear it on 2.0 ohm cartos in a carto tank but not on a 3.0 ohm carto

The "Rattlesnake" sound and the wave form make absolutely no difference in vapor quality that I can discern. I've used both pulsed and non-pulsed regulated mods.

VW being "cruise control" is misleading. Both a VV and a VW rig vape at the same voltage or wattage until you adjust them up or down as wanted. Both are just as easily adjusted. Both can have equally good voltage regulation. The only real difference between the two is that if you use VW set to 7.5 watts on a 2.4 ohm coil and put on a 3.0 ohm coil it's going to automatically adjust for the wattage you last used: 7.5W. If were using VV you would need to up the voltage manually to maintain the same vapor quality with 3.0 ohms. A VW rig will automatically compensate for an aging coil that is changing resistance. A VV can't do that, either.

I love my itaste VTR.

Sounds like this would be the reason Provari claims that as the battery lessons power the hit doesn't change like most devices? I know that my Triton VV does this.

PWM has nothing to do with the voltage lag that may occur during discharge. The power of the hit, or delivered voltage to a coil is dependent on two things.

1. Battery capacity
2. Quality of Regulation circuity.

A higher capacity battery (like an 18650 rated at 2000mAh) will have more "umph" to it even as it discharges, and thus each time the battery is drawn from, it doesn't tend to lag as much. Higher capacity batteries will also lag, so the battery itself isn't the only thing. The KSD Kmax, for instance is a REAL bad mod (as reviewed by pbusardo), it has horrible voltage regulation circuitry. This is where good voltage regulation circuitry comes in. The ProVari has best in class voltage regulation. There is little doubt in this.

The Triton VV has a lower capacity battery and most likely does not have the quality of voltage regulation circuitry a ProVari has, as a result, you get decreasing hit as the battery discharges.

There are plenty of less expensive mods that that use PWM (like the Sigelei VMax 3, The Smoketech SID, or the Vamo) that use unfiltered PWM on the output but still provide the set voltage all the way through the entire discharge cycle. One could argue whether or not these mods do so with the high degree accuracy that the Provari does.
