Carto Size Theory

[Kemosabe]

So I've been noticing how the size of the carto influences the level of voltage needed to produce optimum vapor. to me, its a characteristic very similar to ohms, yet i dont see much talk about it here, or on supplier's websites.

i am finding that the larger the carto, the more voltage you need. its almost defying what the resistance of the carto is. for example, a super shorty resurrector is rated at 1.7ohms, but most if not all of the ones i have are 2.0 exactly. i also have some EMDCCs that come in at 2.0 as well.

i am able to get significant clouds from my super shorty resurrectors at 3v. if i hit an EMDCC with 3v, the result is pitiful. im guessing this is due to the large area of the EMDCC. my bet is that most of the heat is lost to the body of the carto itself and possibly the filler. the same is true for medium sized cartos- they need just a tad more heat than the smallest ones. the larger the carto, the more voltage i need to get the correct amount of vapor.

so my questions are, how can we account for this? is there some sort of adjustment we can make? say for example you have a 2.0 ohm carto, but it holds X amount of juice more than the standard, so you will need X amount more voltage to get the right hit. or with the super shorty, youve got X amount *less* than the standard, so you'll need X amount less power. IDK maybe its silly and we should just crank up or down the volts until it feels right.

my other question is, will special devices like the Provari and the Darwin account for this phenominon? does the Darwin recognize that you are getting a more robust draw from a smaller carto that has the same resistance as a larger carto? is this a wattage thing, or is this just a juice delivery system phenominon?

I vote for the "juice delivery" theory. If there's more juice & more stuffing it might take more power to deliver it? IDK. Someone with more education than I will be along shortly.
Good question tho. I was gonna place an order for some XLs or XXLs. I'll wait to see what they say about this.

myself i run between 1.7 to 2 ohm on my 3.7v mod but my 2.5 ohm atty puts clouds out on it but gets hot as heck if i hit on it to long. myself i don't know much about this stuff yet but i am learning more each day but from what i can tell is if you have higher ohm you pull more power and more power = more vapor but less battery life. but i could be wrong it is just what i have seen in my test

man i messed up and don't want to edit it. what i wanted to say was look at it like a car stereo system the lower the ohm on a speaker the more power it will take to push it and it will hit harder but a lower ohm will take less power to push. if you use a 1.7ohm duel then you will use less power than a 1.7 ohm single but the duel will put out less because of the lower power it takes. if you have a 4 ohm it should put out more with less power but more volts than a 1.7 at 3.7

any other experienced heads care to weigh in on this topic?

[Kemosabe]

i am extremely surprised that no veterans have attempted to weigh in on this topic. are no vets reading this, or do the vets not know what im talking about?

surely someone before me has recognized that larger cartos need more voltage than their alike resistance little counterparts.

Ok, here we go.. using your 2 cartos as an example.

Carto 1: Super shorty measured at 2 ohms vaped at 3.0v
You are drawing 1.5 amps of current from your battery and producing 4.5watts of power (which is not really a lot).

Carto 2: EMDCC measured at 2 ohms vaped at 3.0v
You are drawing .75 amps of current from your battery and producing a paltry 2.25 watts of power per coil. Hardly anything to write home about.

How did I reach that low a number? Simple really. Your EMDCC is an Ego Mega Dual Coil Cartomizer. You have two 4 ohm coils in there running in parallel, and as such the current you are supplying is divided into those two coils and is in effect halved thus producing paltry results.

For you to replicate the same vape as the super shorty with the EMDCC, you would need to use a variable volt device and set it at 4.25 v, which will then use 1.06 amps of current while putting out 4.5 watts of power.

Does size have anything to do with the amount of vapor? No! Does size have anything to do with the "temperature" of the vapor? Absolutely. The Super shorty coil is basically less than an inch from the end of the carto, whereas the EMDCC is much further away. Similar to somebody using a pipe with a short stem vs one with a longer stem. The vapor will be the same, but it will be a lot cooler due to the distance from your mouth.

Hope this helps clarify matters.

i thought a 2.0ohm EMDCC had two 4ohm coils, giving a total resistance of 2 ohms. i cant find the 2.0 ohm one as its been a while since i purchased it, but here is the 1.6ohm one. the description shows that its two 3.2ohm coils.
510 Ego Mega Dual Coil Cartomizer - 1.6 ohm, clear

i guess more info would be needed on why a large 2.0 ohm carto behaves differently than a smaller 2.0 ohm carto. however, i do like the temperature theory you have introduced. perhaps the temperature of the vapor creates an illusion of more TH. heck, maybe its not an illusion at all. maybe temperature is a huge factor in TH. i like where you're going with this.

i also would like to comment on the part of your post that starts with "carto 1:". 4.5W of power. not a lot. i couldnt agree more. its about half the watts of what i like to normally vape at. i was floored when i got the mini resurrectors. completely blown away by the TH i was getting from 3v (or 4.5W as you more accurately put it). and this is the reason why i even made this thread in the first place. its downright remarkable how this low of a number of watts is giving me such amazing TH. i am always on the hunt for mre TH, and never would i have guessed that a tiny little carto at 3v would have been what i was looking for. i appreciate you weighing in on this Dusty. and Atty, youve got some good knowledge too, i just know it please give us your opinion if youve got a moment.

Ok. Let's see if I've got this.
If I want more throat hit, I should stick with a regular sized or shorty 1.7 ohm cartomizer & forego buying an XL or XXL 1.7 ohm cartomizer. Right?
Vaping on 3.7 v Kgo.
BTW. You guys are awesome. Everyday you teach me more.

By the way, ive seen others use these initials, but what is an"EMDCC "
