How accurate are vw mods really?

[BigGOOSE]

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

Your taste will change just because steam engine says to hit a coil at 49 watts dosnt mean you will like it there. But it will get you in the ball park of where you might want to be. Be a dare devil hit it at 50watts. Everyone's taste is subjective.

Some of us vape in the 6-8watt range, so a mod which can regulate down is important. Most times I am under 4 volts. Some mods can't even go down that low, in practice, so accuracy is important, not that I vape by watts or numbers...

My mod can't buck lol. My current one. I would just build low if I wanted to vape low

Kind of defeats the purpose of VV or VW...

Just because you vape with low power does not constitute accuracy. Can you really taste the difference in a tenth of a watt? Or hundredths of a watt?

There's a bunch of different features/stats being mixed together in this thread. It's confuzzling me.

1 - does the mod read a coil accurately?
2 - what's the voltage drop?
3 - does the mod really put out the watts/volts you set it for?
4 - does it do that using Mean or RMS?
5 - can it buck down for a setting lower than battery voltage

These are all distinct features of the chip (well, vdrop includes the whole mod design), and you may or may not care about each one for the way you vape...

There are plenty of cheap mods which are way off; some can't even go below battery voltage. I can taste the difference between 3.8 volts and 4 volts...

Somehow my original post was duplicated. Deleted one.

 

[stevegmu]

3.8 to 4 volts equates to almost a watt difference in a 2ohm coil. So no you cannot tell the difference. What are the devices that can't regulate below battery voltage I'm curious ?

Many, many mods can't. Most China mods are pretty inaccurate. Certain DNA chips can't down regulate, pretty sure the MVP has or had this issue...

I have it for boosting. I don't vape anything under 20 watts these days. Hardly under 30. Don't judge my vaping style and I won't judge yours

It seems you had difficulty understanding my posts...

True about it being accurate reading coils. Which ones are most accurate? What does rms and mean mean? I know rms stands for roof median square. And I'm assuming they all pull out the volts you set it for

I typoed go back and read. Once again I have vw so I can boost my voltage to heat coils more and faster

Thanks man. How is that smok tfv4on the x cube 2? Thinking about getting that as my next setup

Actually, I should include the "PWM" (pulse width modulation) issue in that same bullet.

It's a matter of "how does the chip try to hit your voltage?".

For example, if you set something for 5 volts, a chip can get there by giving it 10, then 0, then 10, then 0. The average is 5, right? If it does that FAST enough, it might be a smooth vape. If not, maybe not.

Anyway - then there's PWM, which changes how LONG the device pulses, not just how high. Another way of attaining an overall approximation of what you've dialed in.

Or something like that.
I mostly run a mech now. lol

Your quote got messed up somewhere. But I love the xcube and all of its quirks. It's gimmicky but it's always in rotation on a daily basis. The tfv4 is spectacular in quad coil mode at 100 watts. Not a flavor chaser by any stretch of the imagination but if you want dense warm clouds and like to guzzle ejuice then it's your thing. I've kinda backed off it till my sextuplet coil arrives. I refuse to build on the RBA that tank is strictly my cloud chasing tank.

With all the stuff they just keep shoving on the market, I have the philosophy that it's going to be inaccurate unless proven otherwise. That's why I currently only DNA and SX350 devices.

Most of the Chinese mod manufacturers use cheaper, less sophisticated regulating chips in order to decrease production and sale costs, which use "mean" and not "RMS" regulation. These are not capable of down regulating power (they can be widely inaccurate, especially at lower voltages). They can't output voltages between 3v and 4.2 volts even though their display say they can and are. Therefore, they may appear to be vaping "hot" or harsh at lower wattage settings.
