Does an MVP 2.0 Use Watts and Volts at the same time ?

[StealthBombing]

Super noob question, im trying to get my wattage and voltage perfect but im a bit confused;

Hardware: Protank 3 with 2.0 Ohm Dual Coil head
Battery: MVP 2.0

Currently vaping this thing at 10 Watts and 4.5 Volts but here is where i get confused. Ive read topics saying if you adjust your watts it will automatically adjust your volts for you. So lets say i set it at 10 Watts and manually adjust the voltage where i want it as well which one does it use ? am i vaping 10 watts or 4.5 volts ? Can someone please clear this up.

thanks

Hi Stealth... let me see if I can clear up a few misconceptions for you...

Wattage and voltage adjustments are independent of each other. If you set wattage, and go back to voltage... the voltage will be what ever it was set at the last time you were in voltage mode. Voltage will not change on the screen, because you changed wattage.
Voltage will adjust via the microprocessor based on wattage setting and atomizer resistance... but you don't see that happen on the screen. Set your voltage to 3.3v. Now go to wattage mode and set it at 11 watts. Briefly fire the atty. Now... go back to voltage mode... still 3.3v right? See what I mean?

The available options are:

1. Press both buttons - Atomizer resistance and remaining battery voltage.
2. Press 'U' and you go into voltage adjustment mode. You get "puffs" - then you see your last voltage setting. continue to press the button, and it will cycle to it's max of 5v, then back to it's base 3.3v. If you stop right there, you remain in "voltage mode" at what ever you set it at... and wattage mode is disabled - until you enter wattage mode.
3. Press 'P' and you go into wattage adjustment mode. You get "puffs" - then you see your last wattage setting. continue to press the button, and it will cycle to it's max of 11w, then back to it's base 6w. If you stop right there, you remain in "wattage mode" at what ever you set it at... and voltage mode is disabled - until you enter voltage mode.

Voltage is still delivered to the atty... but in wattage mode it is a - not visible on the screen - variable based on ohms law based wattage setting and atomizer resistance.

Watts, volts, and ohms are related to each other by an equation called Ohm's law. If you have two of them you can plug them into the equation and get the third. A variable wattage mod, like your mvp, will let you enter a wattage you want, read the resistance of your coil, and do the calculation to set the volts.

With your device you can also just give it voltage. The two settings are independent from each other, the voltage you set has no effect on the wattage you set and vice versa.

With a wattage set if you change your atty to one with a different resistance the next time you fire the MVP will realize you changed it, read the resistance again and calculate a new voltage.

Newer chips, like the DNAs, do not allow you to set the voltage. They only let you select a wattage.

With all VV/VW APV's you can set the V or W, one or the other.
Whatever you set or checked last is the mode you're vaping in. (V or W)

So if you set it to 9 watts then set it to 4volts you are vaping at 4v, set it at 4 v then set it to 9 w you're vaping at 9 watts.

Bingo! It'll stick with the last setting that you use. Me personally, I've all but abandoned VW and always use voltage. I've tried it on a several of devices (eVic, VAMO, MVP) and find it just too inconsistent.

Just pick a power "method" to control your vape. Some prefer Watts, others volts. It's a personal preference. In the end, either one delivers the same thing.

I'm still a "Volts" kinda guy myself using the MVP2 and generally stay in that mode. And the Provari owners have no choice.

I thought you were also supposed to use the 'rule of thumb' not to go two whole points over your coil?
So:
1.5 coil=no more than 3.5 V
1.8 coil=no more than 3.8 V
and so on..

The +2 is merely a starting point. Some will want it a little higher or lower, just personal preference

That works well with most clearos with smaller than 30 gauge wire.

hmmm makes more sense now, so if i set my MVP to 10 watts what does that equal out to voltage ? is that a better vape then just setting the voltage to 4.3-4.5 V ?

 

[JoshUng]

You always use all four (volts, watts, resistance, amps). On the MVP, whatever setting you are on is what dictates the rest. So if you have a 1.5 Ω Coil, and the MVP is set to 4.2V, the wattage will be 11.76W. Now, lets set you switch from variable voltage to variable wattage, and change the watts to 10W, the voltage would be 3.87V then. If you switch back to variable voltage, the MVP will use whatever you last set that to (in this example, 4.2V). The setting you choose to control will make the MVP ignore the other (if you are in variable wattage, the MVP will ignore that you last set the volts to 4.2, and will use the proper voltage and vice versa)

There are a bunch of these online, but here is a handy Ohms Law calculator

You are getting too bogged down on the numbers. If the flavor tastes great to you then it's the correct setting.

 

[Mogar]

The easiest way to put it is this....
Wattage = W
Voltage = V
Resistance = R
W =2V / R

I am still working on this myself, so I might be wrong.

What is the resistance of your coil? A lot of ppl start out small on the volts say 3.7 then go to 3.8 and so on when it tastes the best that is what you keep it at.

 

[Buggainok]

To each his own I say. If you are the techy type and love fooling with numbers, charts, volts and ohms, there is lots of good advice here. I just want to vape and not smoke. I set my MVP 2 on 8.0 watts using the "P" button and I've left it there. Lots of flavor and vapor, and no smoking for me.

Currently 2.0 ohm dual coil

On the MVP though you have to keep in mind the max of 11w and 3amps. If I'm using a 1.5ohm coil and set it to 5v it will not run at 13w and 3.3amps. It will set itself to the lowest safe value within the devices limits.

 

[MWilli06]

Yes and no. When you use voltage that's your setting and wattage is irrelevant. When you use wattage it auto detects the resistance of your coil and adjusts volts accordingly

I had asked this question before and was told that the MVP will not exceed the 11watt or 3amp limit no matter what volts you set it too.

So basically i should be running 14 - 15 Watts to get the most out of a 2.0 ohm dual coil head ? that seems unrealistic considering the 11 W max on most devices
