Brand new to VV / VW - Have question

Status
Not open for further replies.
I just recently purchased my first heavy duty vaping device. It's an Innokin SVD. So far I'm loving it. It has Variable Voltage and Wattage controls.

I've searched the internet, and through here a bit, and I have not found an answer to my question. What is the difference between different voltage and different wattage on the same device?

I've seen posts about the differences between a VV device and a VW device, but I have not seen what the difference is between using different wattages or different voltages on this device.

Do they effectively do the same thing?

The quality of your vape is directly related to the wattage you're using.

Maybe this will help:

In case you can't open my link, I'll copy and paste:

Disclaimer: This is the most simplistic explanation and is addressed to new vapers mostly or vapers who are happy within the recommended "just right" power zone (4.5-8.5 watts). If you are using dual coil atomizers or are interested in high wattage vaping, it's a different conversation altogether. :) You will also have to understand the concept of amp limits and how it applies to high power vaping.

Ohm's Law as it pertains to vaping is really not that complicated--and it's very useful when you want to know what you're doing.

Voltage and wattage are often misunderstood by new vapers. Wattage is the power (heat, sweet spot) that your PV (battery and atomizer) generates. Wattage = Voltage (of your battery) squared divided by Resistance (Ω) of your atomizer [P=V[SUP]2[/SUP]/R]. If you're not good at math, don't worry, use this easy calculator:

Online Conversion - Ohm's Law Calculator

Of course, if you own a VW (variable wattage) device, you don't really need this calculator because your device will do the math for you.

The wattage you want, especially at the beginning of your vaping career, should be somewhere between 4.5 and 8.5 Watts. Anything lower than 4.5 watts may not vaporize your juice properly and will not produce enough warmth and vapor. Anything above 8.5 watts increases the risk of burning the filler in your cartomizers (if you're using them) and even some juices, especially the delicate ones.

There are, of course, other variables, like eliquid and JDD (juice delivery devices) that you're using on your batteries. Seven watts on a filler type cartomizer may feel different than the same 7 watts on a fillerless clearomizer or a dripping atomizer. The same is true for different eliquids; tobaccos, chocolate and coffees generally require more wattage (heat), while fruit and other delicate flavors do better with less heat. Everyone's sweet spot is different--those are just very general guidelines.

If you want to know more, this is a good read:

Experiment and you'll find your own bliss in no time!

The chart below is a good guide to safe vaping, even though some think it's a bit conservative.

Wow, that's great info, thank you for writing all that Katya. Though I still don't think you answered my question, and it's probably my fault for not asking properly.

My question is, my device does both VV and VW. Is there a difference in changing one setting or the other? Does it do anything differently, or are they just different ways of increasing the power (or heat) in my atomizer.

BTW, I'm using an iClear 30 and a BCC mega tank.

With a device that does both VV and VW, you select which mode you want to use it in.

If you pick VV, the device will regulate the output voltage at what you set, regardless of the coil resistance.

If you pick VW, the device will regulate the metered current, at what you set, regardless of the coil resistance.

Some like the simplicity of VW - once you determine the watts that works well with your toppers and juice. Sort of "set and forget" until you change flavors.

They both effectively control the amount of power through the resistance of the coil, and watts is just the measure of that power.

VW devices automatically adjust the voltage to reach the watt setpoint, so manually changing the voltage does the same thing.

Katya did a great job with the explanation.

Basically using the same ohm atomizer increasing the voltage portion effectively increases your watts. When changing delivery devices of different ohm you then have to change the voltage to get your watts. Using the variable wattage part of the svd, putting any delivery device of any ohm will not change the watts you set it too.

Basically they do the same thing just arrive at the final setting a different way...watts.

Other factors will play a role, but that is the most basic. Of course too low ohms won't work on a svd.

I'm trying to understand if I understand your question correctly. Wattage is what it is all about. The power of your vape. If you set your device to watts, you don't have to worry about doing the math. Your PV will read the resistance of your atomizer and adjust the voltage accordingly to reach the wattage you like--you can of course adjust the wattage up or down if you like.

Voltage is only a variable in the equation; you need to know the resistance of the atomizer (or check it on the Ohm reader) and then do the math to figure out what the resulting wattage will be. In other words, running your PV in the power mode saves you two steps--checking the Ohms and calculating wattage. Many experienced vapers know exactly their favorite settings in volts and watts by heart, so it doesn't matter much to them. But I like the power mode better. It just makes more sense to me.

Other than that, both modes are fully adjustable.

They are essentially one & the same. Adjusting the voltage in relation to your resistance results in wattage. By using VW you are setting what you want the end result to be. Also, when you use VW, most mods will detect what resistance you are using and adjust accordingly. Keep in mind that as your battery drains you may have to adjust the wattage as you are not getting the same power as when you have a fully charged battery. From what I understand though, the Provari is an exception to this. I believe it maintains the same voltage throughout the cycle of the battery. Could be wrong though.

They're the same, provided you always use heating coils with the same ohms. If you use different ones, using the Watts setting will provide more consistency. I can't think of any situation where VV would be better.

That's correct. Especially considering that atomizers have a nasty habit of changing their resistance as they age and the coil gets covered with gunk or develops a short or the wire begins to wear out somewhere... You never really know what resistance your atty is at any given moment.
