How accurate are vw mods really?

[Scotticus93]

I've read most. Such as the ipv series have 95 percent efficiency. I'm sure some will say mech mods are more efficient but oh well. How far off are these cheap Chinese devices? I read the cloupor mini was notorious for being inaccurate. I have sense upgraded to an ipv d2. But ive always heard stuff like the sx mini and the evolv chips are most accurate. Innokin claims the mvp 3.0 is the most accurate. What do you guys think?

I think the Provari and DNA mods are most accurate. Also "some" of the Innokin mods. It's all in the processing chip used and what Hz the chip uses PWM (Pulse Width Modulation).

Many Chinese manufacturers skimp on the most expensive component (the processor chip) in order to cut manufacturing and production costs, which allows the end product to be less expensive in the short run for consumers. However, many vapers who have experience with both regulated processors believe they can tell the difference in the vape quality.

PBusardo puts his reviewed mods on an oscelloscope, and will reveal what Hz the chip is using PWM.

The Rattlesnake Effect: Why the Provari and DNA Devices Vape Better Than the Cheap 33.3 Hz Mods

Why Provari?

This is a very controversial topic of discussion because many vapers can not tell the difference.

I've found all mods except the SX Mini are in the same ballpark wattage wise. I have most brands with Innokin over represented.

With the SX I run at lower wattages. The SX also uses the chip to control the wattage so its possible with other mods they just burn the snot out of the joose and you stop pressing the button while on the SX you can keep pressing longer.

Note that the above is in wattage mode. The SX also has TC mode but it also controls wattage mode with 5 settings.

accuracy and efficiency are two different things
oh and anyone that claims 95% efficiency on a switchmode regulator is lying

 

[Matty316]

Good question. I know my sxk vapor flask is way off. It shows in realtime how many volts are being used (starts at 0v then goes up as you press the firing button). If i run around a .9 ohm coil on it and want to run it at 30 watts i need to dail it up to around 35 watts to get the voltage needed for 30.

What is "accurate"? Built in ohm meter? But standalone meter is anyway better. Accurate wattage output? Do you really need to know it? Why? You are setting mod according to your taste, not by some numbers from some tables.

turning good power(electricity) into heat isn't that hard...95% efficiency, big woop

 

[realsis]

actually I've tested my ipv4s with the math several times and it has been spot on accurate. The newer YIHI computer chips are very good if not one of the better and more accurate chips.

Fairest point made here. It's not like there's a speed limit for mods lol. I was just curious. I appreciate everyones input. Ipv d2 seems accurate to me but I'm not expert. I'm thinking of getting a smok x cube and just thinking dang I can get a 160w mod for 70 bucks. Sounds good to be true and ive heard its finnicky in tc but I'm so up for the challenge

 

[roxynoodle]

Unless you test your mod over its range of power like Busardo does, you probably won't know, but you can watch his reviews to see which mods are the most accurate.

All I have is an inline volt meter, but it gives me a pretty good idea on my own mods. The sx minis are the most accurate of the mods I own. Actually all of the Yihi chips have scored well in my testing.

My least accurate is the notorious istick 20W which uses poorly implemented pwm. Next is an SXK mod.

In my mind the accuracy of the setting vs what it says on the screen is nowhere near as importaint as being able to actually hold the level I asked for. People forget there was a time we didnt have screens on mods, you adjusted till it vaped good, and the regulation was strictly to hold it there.

I dont think I saw any review recently where the output was horribly off.
There are some devices that wont stepdown, so lower Ohms means higher Watts, no matter what you do.
Then you have the mean vs RMS issue. Istick 20 most popular offender here and I think the first Subox?

Overall appart from those issues it's not that big of a deal. Do you notice if its 28 or 30 or 32 Watts? Really? If so, just dial it up/down until you like the vape.

So what's the real difference between mean and rms. I think ive heard rms is better

 

[tj99959]

My taste buds are far more accurate than ANY meter placed in a PV.
I don't give a damn what the meter says ... if it doesn't taste right ... it isn't right!

Vape by taste .............. NOT NUMBERS! ! !

A quick look at the voltage will tell all.

 

[BigGOOSE]

It's only as accurate as its voltage sensing mode

I agree.

I cant really tell you what exactly the difference is, but most devices are tuned for one of those. If you tune for the other, the output voltage gets higher.
This is a real problem for little clearomizers, which cant handle the higher voltage, even on the lowest setting of the device.
Hope thats somewhat understandable, I cant explain it any better.

Tune for the other? What's "the other" and I don't plan on using little clearos anymore. All sub ohm tanks from here on out

Why would you need such accuracy? You should be more concerned with consistency. They are all within a ballpark of each other. Temp control excluded. But not all are consistent. I havnt seen any huge discrepancies between Clone and authentic.

Idk its like I said. There's no speed limit for a mod. But if steam engine says a coil is good at a certain wattage or a tank coil has recommended. I want something accurate. That's also what I'm talking about. Consistency is what I'm worried about the most
