Voltage vs. Wattage

[Bunnykiller]

VV compared to VW:
VV ( variable Voltage) you set the voltage to work best with the chosen resistance coil you have installed
VW (variable Wattage) you set the wattage to work best with the coil ( I left out the resistance)

Analogy: VV is like driving your car in the hills, you constantly adjust the throttle as you go up and down the hills, VW is like setting the cruise control on. The car adjusts the throttle automatically to keep the same speed.
As your coil ages, the resistance will change a tad, VW mode adjusts the voltage for you to keep things "even". By adjusting the VW (Watts) up or down is equal to adjusting the cruise control to faster or slower...

I may be an exception to the norms. I vape mostly light colored 50/50 24 nic juices on 2.4 - 2.6 Kanger PT2 single coils. I have found with my Vamo V5, (in RMS mode) between 4.5 and 6 watts is my "sweet spot" depending on the juice. This has been true with EVOD, Davide, and Protank 2 tanks. This is my experience only, as anything over 6 watts I get the dreaded nasty burnt taste every time. When I build some lower ohm coils this could change, and hopefully it does. I'd love to enjoy a higher wattage warmer Vape without the bad taste.

It's not unusual - I'm vaping Dekang liquids in my PT2 atm at 7 watts because it seems to get the best vapour and flavour out of the stock 2.2 ohm coil (for me) - next week I'm getting some different liquids in and I'm rebuilding the coils so that may change but vape at whatever tastes good to you - there's no magic formula for getting the 'perfect' vape - everyone's tastes differ.

Voltage vs. Wattage

If I'm reading Ohms Law correctly, it's impossible not to have both!

Ohms Law is a circle, and there are always three ways to get from point A to point B. Point B could care less which of the three ways you choose to use.

Because most of the time I choose to use a mechanical PV, I use VR.

I just wanted to point it out. I'm pretty new too, but based off of Youtube videos, I thought I was all kinds of "doing it wrong" since they show like 1500 watts on a leaf blower mod with plumes of vapor looking like a smoke grenade went off in the room. LoL. This is exaggeration of course, but you get the idea. I'm very happy with my style of use, and so are batteries. 3 full days of vaping pleasure on an Efest 18650 battery.

i'd look into a different tank. my pt2 is a pain in the rump with my zmax v3. one coil i had didn't choke the airflow and when it burnt out, the rebuild choked the airflow. but my mini protanks work like champs with it.

 

[WileECoyote]

I use VW on my MVP2 with cartos and usually stay between 6.5 and 7.5 watts. If I go higher, I usually burn the cartos. The juice is vaping just fine so I guess it is different strokes for different folks.

Just a quick not because all the pertinent information has already been given a few times here.

I may be an exception to the norms. I vape mostly light colored 50/50 24 nic juices on 2.4 - 2.6 Kanger PT2 single coils.

50/50 .

If you use a different blend, instead of 50/50 base, the sweet spot is going to change.

Have you tried Mean? I haven't measured a Vamo, so I don't know if they switched the functions...RMS should be pulse. Mean should be high frequency..pretty close to normal DC voltage(flat).

I think you mainly need to look at your airflow. Airflow and wicking are really the only things you need to consider when increasing power output. I've been vaping 0.7 ohm coils with almost all of my flavors, and I just adjust airflow to accommodate whatever juice I'm using. Liquids that I thought didn't like high power are working just fine with adequate airflow.

 

[Keeferes]

Yep. Tried loads of different settings. Loads of airflow tricks. My juices just seem to prefer lower wattage. I just got some mt Baker vape mail though, so when I try those flavors, it might change. I was mostly just posting so other new people would maybe understand, not everyone enjoys or uses high wattage to get satisfaction.

+10 here...vape at the power level that tastes good... If the controls were labeled as Cold - Cool - Normal - Warm - Hot - Burn yer juice....would you be able to set your PV to a level that tastes good?

The other wild card is the residual heat in your topper, vape your rig at the same wattage / voltage out of your pocket, that's been out in -10 degree weather verses a topper that you've been chain vaping for 15 minutes & using as a hand warmer....very different results. I will frequently adjust my volt / watt levels depending on how hot my atty is, Variable Taste is where it's at the numbers are just there so you can get it close the next time....

This is good information. I've been planning on buying an iTaste so this info is helpful. Thanks.

A lot of good reading here..thanks, folks!

Is this the same for the MVP? If I set watts voltage will auto adjust? B&M in my town didn't say this, they said it was able to set both.

You set one or the other. Watts mode means that if you changed from a topper that is 1.8 Ohms from one that was 2.4 ohms (just using random resistance #s to explain) the voltage would be different to push the same power through the higher resistance. Volts and watts are a different road to the same result This applies to all VV/VW devices

That's great info. Thanks, now the other question is one better than the other? Curious because it seems the volts are able to be adjusted in smaller increments .1 as opposed to wats which is .5

Neither one is necessarily better or worse - its literally 2 different roads that meet with the same end result. Its genuinely personal preference as to which one you pick

 

[CreepyLady]

( you will notice on devices the volts are a smaller whole # apart than watts - like a range of 3-6 volts and 5-12 watts. so you can only move a total of 3 volts in smaller increments as opposed to 7 watts in larger increments - this makes a comparable selection of power options)

Imagine a water tank up on the hill. How full and high it is yields the voltage.
Different sized pipes and valves would be the resistance.
How fast the water flows through the system is amperage.
The water output at the spicket is the wattage.

So, when you alter the voltage, you're using a bigger/smaller tank (or putting it higher/lower in the air).
When you change resistances of atomizers, you're adjusting the pipe size.

With VW, you tell it how much water you want coming out of the spicket (or in this case power for the coils). Resistance is measured, a computer in the PV works out Ohm's Law, and voltage is altered accordingly to get your set power.

VW is usually more consistent for vaping on single coil atomizers from 2 - 2.5 Ohms, since it takes new measurements and adjusts the voltage in real time to achieve your set 'watts or power' several times per second.

With VV, you directly adjust the voltage. To know the resulting power (watts) requires a little math called Ohm's Law. Knowing the numbers isn't that important though...start around 3.7v and adjust up or down to 'taste'.

VV comes in handy when you know you want to force the PV to buck to a set lower voltage so that a low resistance atomizer can fire within a certain current (amp) limit (quite useful with alot of dual coil set-ups). Also, sometimes a PV won't set lower than 5 watts in VW mode, but with a high resistance atty you could swap to VV mode and use the lower voltage settings to run a cooler atty (less than 5 watts). It's also possible with some APVs that might max out at say 12 to 15 watts in VW mode...to get a little more power out of VV mode with the right low resistance atty (still has to stay within the PV's max current allowance).

I had the same misconception my friend, I've figured out that those rediculous sounding wattages and ridiculous vapor comes from mostly wicking and airflow (but most importantly wicking if your using a carto-tank or clearomizer). I thought I was using my tank systems wrong myself because I wasn't getting "competition clouds" and using anywhere near 15 watts. But turns out that land is pretty much only for drippers at the moment, they put half a pillows worth of loose cotton in their rig and that wicks like my ex-girlfriend never could lol (really sucks the juice straight to the coil), so when almost .5 ml can be held on the coils at a time 20 watts feels like a wimpy 5 watts on my aspire et-s (I swear us glassomizers have it rougher, lower watts=harsher vapes). So I'm debating trying out a cheap rebuildable myself so I can use my own "super wick" per se, and watt up there with the big boys. Sub ohming makes it a walk in the park to high watt, because if your below 1 your mod isn't even trying. And if you drill a hole the size of your finger you can use 100 watts if you like.

-And hear I thought high watters were just tougher than me
