variable voltage questions

[jwoode]

I know that turning up the voltage makes a better hit.. it is puffier, tastes better, and seems a lot smoother.
I have been using one of those charts that shows ohms to voltage safe ranges and nothing I have has exploded so I guess I'm ok.

but where can I read up on why it works?
I know it's here somewhere.

What ohm coils do you use and why?
Why go higher voltage?

For example.. I have an Atremis tank with a 4ohm coil and run it at 5.5 volts.
Then the Protank 3's are a 2ohm coil and I run those at 6v.

I'm missing the principle here.

What coils and voltage do you use and why?

I use mainly around 1.5 to 2 ohms just personally i like the vape they produce. i use them at around 6-7 watts just to me thats the sweet spot, depending on the juice you might turn it up a notch or down a notch. it solely matters what you think is the right one. You can get a hang of your range by going up or down a notch.

the protank3 has dual coils. That being said. the resistance is 2.0, so when you have a dual coil you multiply your R by 2. so for the 2.0 dual coil, you have two 4.0 coils.

it's like a fan- you want air, you turn it to LOW-MED-Hi
but you don't know what RPM's the fan is running at...

just start low and increase power till it vapes good
-not good, turn it up
-tastes burnt, turn it down

it's really that simple...

What really matters is the how hot the coil gets, and how fast it gets that way and how the air flows around...
More WATTS means the coil will heat up hotter, and the watts depend on the voltage and resistance in a formula called Ohms Law.
If you've got the chart, you know your two examples are dramatically different - one is like 8 watts and one is like 16 watts...
Are you SURE about that ProTank3 resistance and setting? 2 ohms at 6 volts is VERY high, while 4 ohms at 5.5 volts is fairly low.
A PT3 is dual coil, so yeah, it'll handle a bit more voltage - it's still surprising it doesn't burn at 6v.

Bottom line - some juice tastes better at higher power settings. Some people prefer a "hotter" vape - and they'll get it with higher power settings.

And the overall taste and vapor are effected by all those variables:
resistance and power (volts/watts)
wicking and airflow

a 2 ohm pt3 at 6 volts will give a wattage output of 9 watts per coil, I'm not surprised that it can handle it.

If you want to know why it works, read about Ohm's Law.

Ohm's Law is about the relationship between different aspect of electricity, i.e. current (amps), resistance (ohms), potential energy (volts) and power (watts), those four attributes are closely related.

Understanding these characteristics will help you understand not only what happens in your e-cig, but in your toaster, your flashlight and all those countless other electrical goodies.

If you Google "safe vaping power chart" you will see the chart that I have been following.. and now I'm wondering how I managed to miss-read that chart. I have been using the second chart from the left.

If you look on the left side at the 2.00 ohm, then follow that line across to the center of the green area.. you can see 6.13 in that cell.. which I mistakenly mistook for the voltage.. then follow that column up to the top where it shows a value of 3.5 volts being correct.. ok.. oops.. who looks up anyway?

So what is that 6.13 value where 2.00 ohm and 3.5 volts intersect?
I was mistaking that for the best voltage.

My Vamo registers the Protank 3 at 2.00 ohm.

I just cranked it down to 3.5 volts and it hits very nice.. so maybe I have not fried it.. it don't taste fried.
So on my Artemis at 4.00 ohm, by the chart it should be at 6.25 volts?

I guess charts work better when you read them right.. Thanks for the heads up

 

[jwoode]

a 2 ohm pt3 at 6 volts will give a wattage output of 9 watts per coil, I'm not surprised that it can handle it.

I just turned it down to 3.5v and it still tastes pretty good.. a little less vapor but really it's not bad at all.. but it does make more vapor at 6v.. think I'll creep it up some..

I'm off to read up on ohm's law now

Most people mis-understand voltage and wattage when it comes to coils. Yes, there is ohms law, but that is more to gague how much power is getting to the coils. There are other factors to consider than just how hot the coils work with whatever juice.

Wicking is one of my major indicators as to what to set your coils to. If I had a wicking system that can constantly supply enough juice to keep up with the voltage I am running my coils at, then a higher might be a better solution. However, if I have something that doesn't wick as well, I might want to lower the voltage so I don't run the wick dry and get a burnt taste.

Lowering the ohm coils usually results in a higher temperature per wattage you have it set at.

Now, you said you had a protank and an artemis. The Protank is a bottom coil design. I bet you get more vapor when your tank is half empty. Because protanks draw in the e-juice when you inhale, it's wicking method is keeping up to your higher voltage setting. I bet if you lower your voltage setting, you would get the gurgling sound.

Your Artemis tank uses a cartomiser, so it wicks much slower. It has to go through the punched hole and into the e-juice holding material before it gets to the coil. If you run your voltage up too high,you're likely to get a burnt smell.

I hope this help.

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 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. In short, dual coil atties cosist of two coils configured in parallel, which means that a 1.5Ω atty is really two 3Ω coils--so calculate your wattage based on the 3Ω number--not 1.5Ω.

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.

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.

My E-juice is delicate?!?!?!? I think not! It's...err... MANLY. I say octa coil sub ohm 50a 26650 battery the hell outta watermelon and vape so much watermelon seeds start coming out your...err... you know.

...now come along poor e-liquid.. that bad man won't call you a delicate again. I've taped a good movie from the Hallmark channel, I think you'd like.

My apologies.

As I said, those are just very general guidelines. Some watermelon juices are indeed very robust and require 20 watts of power, at least.

What coils and voltage do you use and why?

A few more words on the subject of dual coil atomizers. A 2Ω DC atty consists of 2 4Ω coils configured in parallel. However, the battery doesn't care how many coils are attached to it--it just reads the final resistance of the atomizer. A 2Ω single coil atomizer will run much hotter than your 2 Ω DCC, which splits the load between two 4 Ω coils (thus producing a cooler but more voluminous--due to increased surface area--vape). The main reason DC cartomizers were invented in the first place was to decrease the heat of the coils to prevent, ahem, all those incidents of burning cartomizers.

The problem with this calculation was that it increased the demand for amps the battery needed to supply and decreased the overall heat (power) of each coil, thus requiring higher voltages.

This is how I see it. Let's say I like to vape at 8 watts. If I tell my PV to supply 8 watts to two coils, my atomizer will not vape the same as it would if it only had to apply 8 watts to one coil--a single coil would be working at 8 watts, two coils--at 4 watts each, more or less. In theory, at least. 8 watts into two coils, each coil getting approximately 4 watts ( if its perfectly balanced) of power, is very different then 8 watts going all into one coil at the same total ohms.

In the real world of vaping, the realized, true experience would be probably somewhere between the two wattage figures--when using a dual coil device.

In my own experience, there is no way I can put a 1.8Ω single coil stock cartomizer on 4.0v (8.9W) and vape it without choking on a dry hit. The highest I can comfortably go with a single-coil 1.8Ω atty is 3.2-3.3v. I have absolutely no problem vaping a 1.8Ω DCC at 4.0v, however. I usually stay lower than that, but I have no issues with dry hits or burnt taste whatsoever.
