Low Res, High Res, Standard Atomizers

[Rocketpunk]

I'm so confused!

I use a vv (a Torpedo VVV and a Kgo VV).

I've decided I like dripping the best.

But I'm very confused on the atomizer/ohm/wattage thing.

So far I've been using joyetech 510 low resistance atomizers. 1.5-1.8 Ohms, and I keep my VV's locked at 4.5 volts. This is my "sweet spot", but I have a nagging feeling that I'm not "doing it right."

If I use a standard atty on my VV's, I need to rev it up to 5.0 but that burns juice waaay too fast. If I'm using a carto, I have to tone it down (4 volts).

I've bought at least a dozen attys since I first started vaping (I refuse to use a clearomizer, those things suck!)

Will a direct dripping expert please explain to me what is the best atty to use with a VV Torpedo (aka Lavatube).

with the amp limit of the lavatube even at what you think you are getting with a lr the volts is about 3.4v. then with a sr witch will work right and should only be set to about 4.5v unless stated by supplier that it is for 5v.

Using VV more or less means you shouldn't have to care much about the ohms - It's the watts of power you are producing (there are several caveats, but that's the basic principal) that creates the vapor. Getting hung up on the volts isn't helpful if you change ohms.

This is an ohms law calculator. In the "calculate for power" section, the third one is what you need (though I'm about to explain why you really don't need it in the next paragraph). If you have - let's say - a 2.5 ohm atomizer and you are giving it 5.0v, you are producing 10 watts of power to create vapor with. If you are using a 2.0 ohm atomizer and giving it 4.5v, you are creating just a tad bit more than 10 watts of power (10.125 to be exact) to create vapor with. In the most general terms, those vaping experiences should be very very similar to one another.

OK - all that said: You shouldn't need to really care much about ohms or volts or, for that matter, the watts either as long as your atty or carto ohms are within the boundaries your device behaves well with. Some VV devices don't play well with really low resistance stuff. --- My advice is this: Put whatever atty on the device and start near its lowest setting. Vape. Does it taste and feel right? If Yes, there you go. If no, turn it up a little and try again.... so forth and so on until you find your sweet spot where the flavor is good, the vapor temperature is comfortable to you, and there is plenty of vapor production. Don't even think about the numbers. Think about what you want your vapor to taste and feel like. Adjust until you find that. Then, there's your spot.

I could stop there, but I mentioned the fact there are some caveats. Let me just drag one out of my bag of tricks as a good example. I run a 2.5 ohm i06 on my REO VVW at 4.5v and am very happy with the results for the juice I've been using in the VVW. I have a 2.0 ohm hh.357 atty on my notcigs VVPV and I run that one right close to 4.5v too. The 10 watts from the VVPV are vaporizing a 100% VG juice and the flavor really comes out there. The VVPV has a 501 drip tip adapter and a drip shield that change the airflow through the unit. That vapor is actually cooler once it gets to my mouth than the vapor from the VVW running at 2 less watts. And, the difference in design between the i06 and the hh.357 is a big difference. The exposed bridge and coil near the top of the casing seems to produce warmer vapor at lower watts... It's an illusion, but that is how it seems when the higher watts hh.357 is compared directly side by side to the i06 being run at lower watts. That illusion is partly caused by the atty design and also partly caused by the extra length needed for the drip tip adapter on my VVPV.

Tune it to warmth, flavor, and throat hit and don't even worry about any numbers.

My advice is don't worry about it. If it works go for it. I simply set it for the lowest and work my way up each time. I have built tons of mods and could give a lecture on ohms law, but once a user has gone VV it is all individual choice.

Thanks, all. So far, I've "accidentally" stumbled upon what works for me. I know a lot of people say don't use LR attys on a VV, but I don't go higher than 4.5 volts. With LR attys on both my Torpedo VVV and my Kgo VV, I have definitely found my sweet spot. They work, and I like them, so I guess I'll stick with what I know.

This reminds me of what a sommelier once told me, "It doesn't matter if you're buying Kendall Jackson or chateauneuf du pape, if you like it, that's all that matters."

I've bought at least a dozen attys since I first started vaping

Wow! If I remember correctly I bought the atty I'm using right now last December.
I use 3 ohm atties (measure 2.8-2.9 ohms on my Provari) between 7.5-8 watts depending on the flavor used. (4.5-4.8 volts)

I'm still learning. I first started vaping with clearomizers, but those things crapped out on me three different times (and on an eGo-T battery, no less!) My friend suggested "dripping". Oh man, what a difference! It's a pain constantly dripping, but the flavor, TH, and vape clouds more than make up for it.

I've had a hard time finding my "sweet spot" with attys with higher ohm, standard or high resistance. I always start low and work my way up, but they just don't pull, hit, or taste the same. I've given away a handful of those standard, or high resistance attys, to my fellow co-workers who vape.

I kinda feel like what I'm doing is counter-intuitive, but it works!

P.S., I am absolutely beyond horrible with math and numbers. I'm an english major guy. Literature and such. I have number dyslexia. Yes, it's true. If I stare at numbers too long, they shift on me. I kid you not, the numbers change if I stare too long.

The point I was trying to make is that if you use an atty within it's proper perameters, it will last almost forever. When we try to use them at voltages beyond what they were designed for they don't last. Once you know what wattage you like to vape at, then you can look for atties that were designed for those wattages. These little 510's I'm using last forever when used in the 7-8 watt range, but I'd be lucky to get one to last a week at the 12-13 watts you suggested in the OP. If you want that kind of heat, there are better atties/ways to do it. For example a 306 atty would taste about the same at 10 watts. An i06 will get you there, as will a 357, but a 510 is a poor choice for that use.
My LR HH-357 is from the first batch that Hanna made, and I don't have to run the voltage all that high to make it kick like a mule. It's lasted because it was made for that type of use.

I can't emphasize enough how much I suck at math. And it's not even a matter of being lazy. My brain just isn't wired to handle math. If you think that's an excuse to be lazy, it is not. I can analyze a Shakespearean sonnet until I'm blue in the face. But, even with graphs and charts to compare, my brain just doesn't get it. Please don't think I'm "playing dumb", but some people are honestly better at one thing than another. My biggest weakness is math.

That being said, this ohms > volts > watts thing confuses the living daylights out of me. Please don't post a chart and say "Here ya go, you idiot." It's all very confusing to me.

"Hi, my name is Billy. I'm a math ......."

"Hi, Billy!"

Am I the only person who sucks this bad at math?

This little "chart" takes all the math out of it for you
Ohm's Law Calculator

If you know the wattage you like just plug it in along with the resistance of your atty and it will tell you what voltage to use.

Here is another alturnative for the math impaired
http://www.electronicstix.com/THEKICK.html
However it has a 10 watt limit.
Just stick one of these in a mod like a Silver Bullet, and it will adjust the voltage for you regardles of the atties resistance.

I don't understand Ohm's Law. I swear to g@d I'm trying. Can someone please teach me like I'm ten years old? Trust me, I will not be offended.

Pointing me to wiki won't help. I've been there. It's just as confusing.

2nd Edit: Please please please don't use acronyms if you're going to explain this to me. Please use the full terminology and the specific words.

Please be as specific as possible. Everything. Devices, settings, everything.

I don't understand Ohm's Law. I swear to g@d I'm trying. Can someone please teach me like I'm ten years old?

The part of ohms law vapers use is this:

Power = Energy Squared divided by resistance.

So, the watts of power you create comes from Voltage Squared divided by the resistance of your coil.

Let's say 4.0volts and 2.0 ohm atty --- 4X4 (voltage squared) = 16. 16/2 (2.0 ohms) = 8. You are running at 8 watts of power.

If I were giving advice, I'd say you might not really need to understand ohms law. You can just take it as fact and use one of the calculators linked to in these responses.

And I already gave the other advice I have. Don't worry about the numbers. Start with low voltage and adjust up until it tastes and feels right.
