VV vs VW...

[Spencer87]

K, So I know I ask a lot of questions, and am kinda piggybacking my hobby on all of you who have already made this a hobby, And plus I Know ABSOLUTELY Nothing about Electronics, and like... Wattage and stuff.


Anyways, Ive asked you guys about Ohms, and all that stuff, and I think I have a firm grasp on the general Concept already, Although I talked to my bro yesterday who JUST started vaping with a Ego C last week, and because of a Mechanic Background, knew what an Ohm was already. and what it did.
Anyways, My New question, and I did try googling this, It didnt weild the results I wanted. I have had an MVP 2.0 for a while. bought my bro one today, Being sent to his house down in Canada.


And I understand kinda that My VV Turns up the heat kinda... more voltage going through my resistance... therefore, pulling more power to put it through the coil, and making my coil emit more of this energy, which in turn burns faster, and more vapor, sometimes too fast, giving it a burning taste, depeneding on my resistance level... Etc. Etc.


Now the real question. Does VW do the same thing? Ive been messing with it for a while... and I think it does something different.. but I am not exactly sure what exactly that is... I mean, I may be wrong on the VV thing to so feel free to correct.... if neccesary

Happy vaping!

With a VV, the voltage you set will stay constant, regardless of the resistance of your topper. So you might set it higher than you should, thereby burning your juice, carto, etc..

With VW, once you set the wattage, it stays there, regardless of your topper. It will adjust the voltage accordingly, to hit the wattage you set. In essence, it's a bit more user-friendly than VV in that you don't need to adjust your settings if you change toppers.

It's kind of like the difference between driving an automatic transmission (VW) instead of a standard (VV).

Does that make sense?

It does the same thing, but adjust it automaticly. It doesn't realy care what ohm your coil is, it'll adjust to the correct voltage for the current coil.

VV = manually adjust voltage. If you got 1.5 ohm coil and adjust it to 4v it would be 10.6 watts
VW = Automatic adjust of the voltage for your current coil. So you'll get 10w either way if you got 2.5 ohm or 1.5 ohm.

Not sure if i could explain it good enough, hope i helped abit!

 

[Spencer87]

OK. I think I kinda got it.. so it keeps messing my voltage to hit the wattage. I got that... so what is the wattage and or voltage doing?
Because I have 2.1 ohm coil on my clearomizer now. Now, I set the volts at 5, Burns my juice. But know sitting on 11 volts now.... and my juice is tasting great.... Dr pepper.

Controlling Watts is the only way I know of regulating a stable power input to the coil.

With wattage set, this power always remain the same regardless of all the factors that can affect it, and constantly change while vaping. The battery that progressivly discharge, the coil that get dirty and the resulting increase in resistance, the properties of the e-liquids that are used, ....etc. Regulating watts will adjust volts to maintain Watts at desired levels.

Regulating volts does not assure a constant power as the properties of the other factors will change as you vape and thus directly affect the power to the coil.

This will be even more dramatic when you change atomizer/clearomizer/cartomizer .

More volts = more heat = more flavour / vapour, if the juice /clearomizer can handle it. Most clearos can't go above 10w without burning.
The wattage is what you get when you combine your 2.1 ohm with voltage. If you set it at 5volts you will have 11.9 wattage.

Wattage is basicly more newbie friendly, just raise it until it hits your sweet spot.

 

[DPLongo22]

At 2.1 and 5 volts, you're sitting at just around 11 watts (if my math is correct). You should be getting the same results setting either the voltage to 5 or the wattage to 11.

If you're burning though, lower either (V or W) until you hit the taste you want. Ultimately, we're all vaping to taste anyway, so which road we take really doesn't matter (V or W). I change either to suit what I'm looking for at the time.

" 11 volts " what do you have it hooked to your car battery?

 

[tj99959]

E2/R = P

or

P = E2/R

Is there really any difference??

E = Volts
R = Ohms
P = Watts

 

[Spencer87]

Sorry. Oops 11 Watts haha

I'm pretty sure he meant watts...

Wattage is not volts, not ohms, and not amps (current). It is a measure of power, or in our case, heat. It's just a measure of how much heat is produced in that coil.

Power is mathematically calculated using the values for the first three, volts ohms and amps. If you screw on a different device, with a different ohms rating, the amount of power will change.

As stated above, a VW device allows you to set a power or 'heat' amount. If the coil resistance would change, the circuitry will adjust the voltage accordingly so that the same 'heat' is generated by the coil.

It doesn't stop you from needing to adjust, though. Different coils, different juices and different wicking abilities will determine how much heat in a particular coil is needed to get best results. Some of my coils like 12 to 15 watts, some of them only like 7 or 8. The smaller coils like lower wattages since you simply can't concentrate that much 'heat' in that small an area without burning. Larger coils like more watts.

But, like variable voltage, it will keep the level constant until the battery runs dead.

I kind of assumed that, which is why I answered in the manner I did (previously).

 

[JimzDogz]

I knew what you meant, I'm just messing with you a bit this morning.

 

[JimzDogz]

Now I feel like I should contribute to the discussion in a meaningful way. When I build a new coil and am putting it onto a VV device, I first check the resistance. But that doesn't tell me where to set my voltage necessarily. I could do the math and find the watts and so on, but even that won't tell me where I like the vape. So, what I do is check the ohms then add 2.1, the sum is where I set my volts. That put's me in the ballpark, I can begin zeroing in from there. With a VW device once you find a sweet spot and change coils, it will put you back into the ballpark. Their by skipping over the steps that I took to get there. It's a short cut to get to the same final destination.

Just wondering, what are the reasons for using to regulate volts if regulated wattage is available on a specific unit ? I may be wrong but voltage regulation was offered first and regulated wattage was an improvement.

Personally I don't see a VW device to be a big improvement over a VV device. It's one of many bells and whistles that has been added to circuit boards and will probably be the standard moving forward. It's biggest advantage is that it makes your mod, for lack of a better term, idiot-proof. There's less chance of someone having the voltage way too high for the coil resistance and maybe frying something. That could still happen, but it's less likely.

Agreed. It's an improvement, but a small one. I change both my VV and VW devices to taste and mood.

Put it this way, if I liked a device VV or VW would not be a deciding factor. As long it's variable SOMETHING, it works for me.

It's really a matter of a persons life experiences, and what's the easiest for a person to wrap their head around. I spent so much of my time working with variable load factors/gear ratios that thinking in terms of VR is the most natural for me.

The right way for any person to do something will always be the easiest way for them to do it right.
