How To Get The Perfect Vape.

hi all
I have a mvp 3 and I use iclear 30 tanks 1.9 to 2.1 ohms
im vapeing at 12 watts 5.1 volts and have been for a few weeks now
everything was fine until today right now in fact hence the reason for this question
I refilled my tank and screwed it back on my mvp when I pressed the button to vape
it reads the ohms and volts and wattage the wattage was as normal 12 watts
the volts were 7.1 and the ohms were 6.0 totally unvapable and burnt tasting
(I should also point out that the volts and watts are locked in on the mvp)
I have also tried the tanks on other devices and still the same issue
which leads me to believe its the tanks at fault and not the device
I have been vapeing long enough to understand the reasons for burnt taste
and the causes and solutions to rectify it but I have never had this happen before
I tried other tanks and the same has happened except for one which works fine
does anyone have any idea whats going on
thanks

So I decided to try a 1,6 ohm coil on kayfun v4 clone Tobecco and I am using 28gauge Kanthal with a cotton
wick on a Rdna 30 and its vaping well at 15 watts I have a kanger subtank mini coming in the mail and here goes my question
So the kanger subtank states that with a .5 ohm coil i could vape up to 30 watts but the voltage comes in at like 3.8 volts
I was under the impression that the rdna 30 needs at least 4 volts to work which kinda brings me to my second question
What is the point of of sub ohms? cant i just build a 2.0 ohm coil or something like that to achieve the results as if i was subohming
I am very confused on this
thanks for the replys in advance
Oh yea is a 1.6 ohm coil at 15 watts a normal build or any recommendations for the kayfun v4 for watts and ohms thanks again  

So with unrestricted mechanical mods, how does one know how many watts, volts, and amps being applied through ohms law? Is it solely the voltage charge of the battery installed that will determine everything else because of how ohms law works?  

Hello Been vaping about 2 years now
My setups are Vaporshark Rdna 30 Istick 30 watt and a provari 2.5 and a IPv mini v2 30 watt
So like many others I have been juggling with wattage I currently Use A couple of kanger subtank minis using the RBA and a kayfun v4 I've been all over the place building ohms but have settled on 1.2 - 1.4 ohms BTW I'm not into sub ohms
So after many months of different ohms and watts with the help of steam engine I have found I like my vape at a heat flux of around 175 so to get to this and I can't believe how simple it was I just take the ohms I am using such as 1.2 @ 12 watts = 178 heat flux 1.3 @ 13 watts = 178 heat flux and so on I can't believe it became that simple
So I suppose all it takes is to find what heat flux you enjoy and adjust from there
I never bought that what I have read thru the last 2 years that 14 watts is 14 watts no matter what ohms you use it seems to me there had to be more factors involved
Just my thoughts

Somehow, I inadvertently pushed the buttons just wrong today and it went from 7 watts (my usual power setting) to 50 watts (the highest setting). I didn't even mean to push any of those buttons.

I experienced instant burnout and a horrible taste in my mouth and the coil was instantly ruined.

Do people really vape at such high power? If so, how often do you have to replace the coil? And how many ohms are you putting that through? The coil I replaced it with is 1.77 ohms which is about the same as the one I burned out.

50 watts seems so excessive to me that I double-checked and yes, that's what it says it goes up to. Even at 7.5 watts the coils seem to burn out too fast which is why I vape at 7.

I feel like Nigel Tufnel designed this thing. "But it goes to 50. That's 43 higher than 7. So it's like 43 more. So when you're vaping at 7 watts and you want that extra push over the cliff..."

(I'm actually impressed that Nigel could do the math to figure that 50 was 43 higher than 7)  

Okay so my target is to get .12 ohms consistently, doesn't fall apart, 3mm diameter, 4 loops. Fralien has one I find is best for my needs. However, the cool down time is too long and its still cooking that wicking, because the size of the coil outside diameter.

I've tried a few coils, like this wire mesh stuff, 4 loops, 3mm etc, .14 ohms. This to me is very uneasy and just inky dinky.

Main goal is for quick .13 ohm 85 to 90 watts, 3.8 volts fire up and possibility of much less cool down time in case I want to chain vape. No I do not get hot spots or dry hits, but I do taste how the cotton life is, pure and hybrid with canna.  

So I've been looking through different posts and I'm still confused about the difference between watts and volts. I'm looking at buying a vv4 and I figured it would be a good idea to understand what exactly I'm buying before spending the money on it. While I was looking through the forums, I saw words like sub-ohms and ohms being thrown around so IF someone wants to explain that I would be eternally grateful otherwise that's the next lesson I'm planning to learn.  

So I need to make sure right off the bat that no one misunderstands this post as somehow an attack on any vaper of any kind. I'm posting this because I have become genuinely curious and feel I may be missing out on my vaping experience. I've had an APV of some kind or another for the last 2 years or so, nothing ever real fancy or expensive (I just got an istick 50W and love it) but APVs none the less. I have found that I only really vape at very low Watts/Volts compared to many on this (as we speak I'm vaping The Virus in an old original model protank with a 2.2ohm coil in it at 3.8V--6.5W). Now it's not because I don't own a device that can reach the Watt levels I want, any of them can; in fact, I purchase higher resistance coils so I have a bigger range to vape at. My first VV battery was an ego style twist, and I have always kept with the same mentality (again, I'm not suggesting this is the right way, or better than others at all)-- I start at a low voltage, hit it, and continue to raise it .1V at a time until I get a burnt hit. I dial it one down, and there I am. Now I always use the Variable Voltage setting, and where I vape usually works out to be in the 5.5-7.5W range. Now, I have noticed that this is astoundingly low for the devices I use. My question is: when vaping at such high Watt levels, how can you taste the juice at all? I mean, at home (obviously not out in public) I would love to be getting even more satisfying vapor from these devices, which is clearly possible. So what am I doing wrong? What am I missing? Why is it that in the 6-7W range even my hits taste so burnt and dry I would never dream of continuing? All of your information/advice is greatly appreciated. Vape On.  

I have a new istick 30w that I use with a smok micro adc2. I've used it with a new 2 ohm coil at 8 watts and is great. I changed to a used coil I had cleaned and things got weird. It's a 2 ohm coil and the istick is reading it at 4.9! At 8 watts the throat hit was too much so I went down to 6 watts. According to the manual the istick doesn't even fire to 4.9 ohms. So let's see what you got?  

Due to a recent rash of vapers using mech mods without proper knowledge. here is a simple test for vapers who want to use unregulated devices, if you can confidently answer these questions, you just may be ready to take the plunge to a mech or unregulated box mod. If you cannot answer all of the questions, don't be discouraged, use the test as a base for the knowledge you may need to acquire.


1. Define ohms law using a short paragraph, and show the equation below.

2. Define watts law using a short paragraph, and show the equation below

3. Draw a simple open circuit.

4. Draw a simple closed circuit

8. You are wrapping a dual coil set up, while pinching your coil with metal tweezers you accidentally press the fire button,

and what is the procedure in this situation?

10. What is the lowest safe resistance of a 4.2v lithium ion battery rated at 20 amps?

11. You have been using a battery for several hours now, and have noticed a sharp decline in vapor production,
why is this happening?

12. You wrap a coil that reads .42 ohms on your multimeter, what important factor should be remembered while using this coil?

13. You are using 2 stacked 18350 lithium ion batteries in your mod, what kind of circuit is this? what changes because of this?
what does not change?
