Is there any difference between a 3.7v + 1.5ohm & a 5.6v + 3.5ohm? (SAME Wattage Power, Ohm's law)

[nocturn4l3030]

Hey guys, jumping into my first Variable Voltage mod, the ProVari.. should be comin in on Monday hopefully

Anyway so messing with the Ohm's Law Calculator.. and my current setup is a 3.7v with a LR 1.5ohm attie, and the Power comes out to 9.12 Watts

So to duplicate that with the HR 3.5 atties I got for my Provari, I would have to set the volts to about 5.6v.

Was just curious if there's any difference in vapor, throat hit or anything at all between the two, despite that they both produce the same watts.


I'm anxious to try out 5v-6v, because I read some people weren't satisfied with 3.7v despite the fact they were using LR atties.. and I'm wondering if it's just because of the fact that you can get more than 9.12 watts of power... but then i question if i'm going to be burning my juice.

thx

Too many watts will burn your juice, easy fix let go of the switch sooner, or don't push it too soon.

The wattage will be exactly the same as you calculated, but it is distributed over different size and length of wire in the coil, more wire (high ohms) means more juice touching more hot wire, more vapor??

I dont know about tecnical things. You say higher Ohm will implicate more wire, so does this mean the heat is distribuated over a bigger surface, being not so concentrated at one point as a low Ohm=high resistance carto of the same type?

If this is so taste would be better, cleaner I think.

Can you confirm this?

This is very interesting, if it works this way, I would go to High ohm high voltage vaping.

I saw difference immediately. I used 3.7 box mod with 1.5 cisco as my set up a month ago. Since building my VV box I now vape at a little over 5-5.5 V on 2.8 = 10ish watts? Ya its awesome. 2 sec drag = to a 5 sec on a 3.7 with LR. Only problem is that I have bought new attys at 2.8 and they not performing as good as this 4-5 month old atty. I an afraid that this one will die and the replacements not going to perform as well. That is going to be a sad day.

The overall heat will be the same, however, there are physical differences that can effect vaping experience, mainly, how that heat is delivered to the juice. This is one of the reasons for the popularity of dual coil cartomizers. They generate twice the heat, but across twice the area. That results in a cooler vape more voluminous in vapor. Big difference there. So, you'll have to experiment with it. The power you vape at gives you an idea, but in the end, you just have to try it for yourself. Every atomizer or cartomizer type has it's own sweet spot for your personal vaping style. Generally speaking, you usually have a range of power you prefer. For me, it's almost always between 6 and 8 Watts for any carto/atty.

Sounds like you havent tried vaping 6v before buying a VV provari. Good luck. VV devices are ok, some folks swear by them, I fins a good dual coil cart gives me as good a vape as a 6V vape. 5Volts is ok, but I always go back to myHelix or SB and vape at 4.1 or so and get the best vape for me there.

I can confirm that the same juice will taste different, better or worse will depend on your tastes. (I can't believe the flavors some people will vape) LOL

Seems every vaper has their own favorite flavor, voltage, carto - atty combination and there are enough varieties for sale no two have to be the same.

As CraigHB wrote, find the wattage you like, then experiment with flavor and atty - carto combinations at that wattage to find your sweet spot.

cool thx for the responses guys, i never knew the coil was larger in higher ohm atties so ya i guess i'm going to have to see for myself.. i'll post back here to let people know my opinion too for anyone interested

haven't messed with atties yet.. that's a whole nother monster i don't have money for yet ;D just dripping and squonking for now

Is this 6 to 8 watts per carto, or per coil, or if it is a dual coil, those 6 to 8 watts would be somewhat higher in any case?

I´m still not sure if I understood this well, Higher ohms, would implicate larger coils or wires. Is this what you are saying, or the opposite, higher Ohms shorter wires?

 

[Bdbodger]

Nichrome wire comes in different gauges as well with different ohms per foot Nichrome Wire so it may also depend on what the oem used .

don't forget that unless you are currently using a PV that tests out at true 3.7 volts, your calculation won't hold up... no?
I mean most so called 3.7 PV's are around 3.2 to 3.4 true voltage. ... and as the battery looses charge, the voltage goes down.

the provari is "regulate" variable power; so the power is boosted to true voltage through the charge cycle of the battery... every vape will be the same.

you won't be wanting an LR of course (and the vari is amp protected so it won't work on LR atty), but just saying that i like "regular" attys on my Vari. you get more range of use... and in my experience attys resistance goes up as it wears... ymmv.

3.5 is a good choice too though. any higher and you're pushing the top range of the vari.

(i got some HV attys from some vendors that were like 4.8 Ohm by mistake)... i like anywhere from 2.2 to 3.5 Ohm.... happy vaping!

I haven't actually used the dual coil cartos, just basing my comments on what I've read from others. Though, it's on top of my "next to try" list and I'll be picking some up soon. The Boge cartomizers I use most often are similar in construction to the dual coils (the wrapped type) except they have one coil. I'm already pretty comfortable with that style of cartomizer.

You can actually get a good idea of different power ranges just by playing with resistances. For example, the Clearomizers are available in 4 different resistances from 2.4 to 3.2 ohms so that can give you a pretty fine increment with a constant voltage. It's not like there's a huge difference from one tenth of a volt to the next. For me, it takes more like half a volt before the difference really stands out.

I've been using VV for quite a while now and based on my own experience, you tend to find one setting for an atty or carto and stick with it anyway. If you can find a good spot playing around with resistance instead of voltage, that can work just as well. I think the biggest benefit of a VV device is the consistent vape. You don't get that reduction in performance as the battery discharges. That's always been a biggie for me. Second would be the ease of adjusting power on the fly. You can do the same thing by adjusting resistance, just not as easily.

Once you find a wattage that you like to vape at, say for you it is 9 watts, it is very easy to duplicate it with different resistance atomizers or cartomizers.

The voltage formula is the Square Root of Wattage times resistance.

So for 3.5 ohm atomizer that you would like to run at 9 watts: √(9 x 3.5) = 5.6125 volts.

BTW: It really doesn’t matter what the Atomizer or Cartomizer was sold as ohm wise. The can vary tremendously. You need to test it either with a DMM or with your soon to come Provari.

BTW2: For any voltage calculation you do, it is better to walk up to the calculated voltage and see how it hits. For the about 3.5ohms @ 5.6volts, I would start at 5.3volts and bump it up until you hit the sweet spot.

 

[pimpe]

I have the exact same dilemma.
I have a Apex Alpha Ultra pro and I have tried both
3.7v on 1.5 ohm atti = 9.12 watts
and
6v on 4.2 ohm atti = 8.5 watts

but i find that the 6v setup gives a better throat kick...
i can't understand why but that is what i feel.

it feels like the 6v setup give thicker vapor but when i blow it out they look around the same..

Can some one tell my why high volt will have better throat kick even if the watt output is the same?

 

[CraigHB]

Using the same wattage on two different resistances is not always going to provide the exact same experience. Wattage provides a good general indication, but you also have to consider the physical differences between the coils, for example, axial versus horizontal or dual versus single. In your case, I would suspect the higher resistance coil is longer so the heat is spread across more area. The 1.5Ω coil compresses more heat in a smaller area where the 4.2Ω coil spreads less heat over a larger area even though total heat is the same. The result is a different experience between the two even with similar wattage.

I also prefer to use a higher resistance at higher voltage versus a lower resistance at lower voltage.

 

[Levitas]

I always go back to myHelix or SB and vape at 4.1 or so and get the best vape for me there.

That is until the battery starts to drain and your voltage decreases

 

[ukeman]

nice explanation... for me the dilemma seems to be that i get a cooler vape with lots of vapor from SR attys (901 especially) in general, at anywhere from 3.6 to 4.6v ... whereas with a 3.5 Ohm atty, at 5.+v, it'll be warm to hot and yes the TH is more...
I don't like strong TH or heat... nor do i like too cool like a lot of 801's give... especially the Canon, which is great for vapor, but no TH at all.
Actually that's not a dilemma ! lol... that's why i like SR atties on my VV's.

The way I look at it is the same juice will tast different at 9 watts from the different voltages, and there is no reason not to enjoy them both.

 

[nocturn4l3030]

whoa old thread of mine ;p

well i pretty much been vaping 6v ever since i made this thread...i literally never touched 3.7 until i read this thread and wanted to see the difference.

ill admit i always thought the 6v had more of a TH punch and just tastes better...but trying 3.7v jus.now
...i dont know anymore haha...

i dont think its fair for me to decide or say anything conclusive because im using two different brands. Cisco 1.5 306s at 3.7 and IKV 3.5 306s at 6v.

Id like to hear from someone who uses maybe 510s from the same vendor at both voltages and see what they have to say.

for now... imo there definitely is a difference in flavor (6v taste much better) and the TH seems to be somewhat identical.. i remember feeling that i got more of a nicotine rush when i first started 6v..but once again it could be the difference in th brand of atomizer.

ill also say that batteries kick ... at 6v. my aw lifepo4s can last maybe 2 days..usually 1 1/2 days...while my aw imr 18650s wouldnt last a full day
