First post and a question

[HybridTea]

Hi all! I am very new to vaping, but I have been CIGARETTE-FREE for 24 freakin' hours. That seems so ridiculous to a non-smoker, to celebrate that, but I know there are plenty of folks on the forum who will know exactly how INCREDIBLE that is. Haven't lit a cigarette, haven't even really wanted to. I didn't know that would EVER happen. I am totally amazed.

I have an eGo-c Twist with a Vivi Nova tank (2.5 ohm, I think.) I am using juice bought from a local store. I have replacement wicks/coils on order as well as an extra battery and some juice that most folk say approximates Newports, my (ex-) drug of choice...for more than forty years!

I have been wandering through a lot of articles, explanations, and recommendations. I still have two questions that I haven't really found answers to: first, what would be the difference in using a lower resistance coil, and second, when the hours on the battery are spec'd, does that mean amount of time on, or amount of time in actual use?

Thanks for any information!

 

[Jwaterski]

Go get a back-up for everything now! And a back-up for that too.
As far as coil resistance, you'll get better answers from others soon.
Battery life will depend on how you vape, an 1100 last me around 10-12 hours light use, 6-8 heavy use.
And welcome, congrats, have fun, and vape on.
One other thing, don't buy tobacco only flavors, get some others, you'll like it!

 

[basylica]

The "mah" rating of batteries is supposed use. 1300= 13hrs, 650=6.5hrs. It depends on how much you vape however.
I was a pack a day smoker and a 1300 would generally last me 2 days.
There are several pages of ohms law for ecigs. Generally for a non variable battery you need to be around 2-2.2 ohms for best performance I find.

 

[MoDmAnDaN]

well...

Congrats and welcome!!!!

24 hours is a stepping stone to the success you want, don't discount it!

Since you are using a VV (variable voltage) device, the resistance is not as big a deal as it would be on a non-VV Ego type battery. What a lower resistance coil...say 2.0 or 1.8 will do for you is maybe give you slightly better battery life. A lower ohm will also give a you a better TH or throat hit. The lower the ohm, the less voltage needed, but requires a higher amperage, so maybe won't really improve battery life all that much.

As Jwaterski has said, battery life is subjective. How a store can state a certain battery will give you X amount of hours is just not right. It depends on to many factors to give a straight answer. The only way you'll know with what you have, is your switch will start to flash when the battery needs charging. So I agree, get a backup and then maybe a backup to your backup.

Congrats!!! and what she said ^^

Congrats on 24 hours and welcome to ECF
Here's a volts to ohms chart that will give you a "general" idea. 2.4 ohms will give the widest range with the Twist.

In regards to juice best to visit local Vendors and sample their offerings. Here's the SF ECF Forum for more info on Vendors:

Best of Luck.

Congrat's Hybrid, that's fantastic! Keep up the good work.
You don't need any advice from me since I see Vapoor eyes er has been here
So ...

 

[nckid4u]

Generally the higher the mah on a battery, the longer it will last. I have a 2800mah and a pair of 2200mah batteries and they last a day for me (no difference in the two for me). I am a heavy vapor, so many will get 2-3 days out of a 2200mah. Always keep a charged one in the holster.

 

[HybridTea]

I am still waiting on my second battery. I may go over to the local shop today and price what they have available, too. Thank you, everyone!
I think it takes a "been there" person to know that a day without a cigarette IS a big deal. I mean, a day without even wanting one. I have never NOT wanted to smoke, not when I had pneumonia, not when I was in the hospital, not ever. Not when I was wearing a patch, even. So I am beyond pleased to have tried this.
I tried it a few years ago with a disposable bought at the gas station on a whim, and I never got the thing to work at all, so I gave up the whole idea until recently, when a chain-smokin' friend told me she'd been THIRTY DAYS without a cigarette. If it worked for her....!
I just bought a similar setup to hers. No more wading through reams of incomprehensible acronyms and opinions and commercial sites that each claim they're the right way to go. The eGo-c has gotten my foot in the door (that would be the door to go OUT into the smoke-free world) and it's good enough for now. Later - who knows?

 

[DetraMental]

I see you have asked and been answered so I'll just say CONGRATS, Hello, and Welcome! Happy Vaping

 

[corvmac]

Welcome and congrats!

Thank you!

I do notice that today I have a bit of a sore throat on one side and vaping kind of burns afterward. Don't know if that's an allergy thing or a reaction to NOT smoking or what it might be. Cigarettes didn't give me a sore throat, I think all the nerves were pretty well deadened after years of doing it.

 

[C1utch]

Lower Ohms:

-Will run hotter producing a warmer vapor
-Will create more vapor
-Will produce more throat hit
-Will affect the flavor produced either by producing more flavor or by diminishing it. This is individual to each flavor.
-Will drain your battery faster
-Will go through e-liquid a little faster which increases the likelihood of a dry hit if your e-cigarette can't keep up with the rate of use

Higher ohms is the opposite of this. To be honest, it comes down to personal preference.

 

[AkGirl79]

I just wanted to say CONGRATULATIONS! That first day is like a "you can do it" bat signal huh?

 

[HybridTea]

I haven't experiences a dry hit, I don't think, but I figure I will know if/when I do!

I don't think I need more vapor then I have, but warmer would be more similar to the cigarette I am used to.

The first draw, when it's been sitting on its side, is the closest to what I'm looking for. Subsequent draws, not as much (but still good - no complaints.)

Definitely one pack down, so more than $6 off the $37 invested. Of course I have almost forty bucks worth of replacement gear & suppplies on order, but at this rate it will pay for itself within a few weeks. Yay! (Though that wasn't a reason for doing it, it's still fun to think about!)

 

[HybridTea]

That first day is like a "you can do it" bat signal huh?

It really is. I NEVER felt I could do it before. Now there is HOPE!

Concerning Resistance - A Short Beginners Guide

Intro Eqns:

[Ohms Law]: V=I*R ;; voltage = current * resistance ;; V(Volts) = I(Amperes) * R(Ohms)

[Power]: P = I*V ;; power(Watts) = current(Amperes) * voltage*(Volts)

These equations are relevant because the temperature of your heating coil is determined by the Power you put thru it.

Interesting side note: power is not a linearly proportional to resistance (as indicated by equations). This is not because math or physics is lying, but due to the fact that some more complicated aspects of physics come into play with actual finite element analysis of the burning process, such as linear resistance and aerodynamic effects on temperature and flow rates.

Algebraically Isolating One Variable:

I = V/R ---(substituting back into P=I*V)----> P = V*(V/R) = (V^2)/R thus, P = (V^2)/R
Result: P = (V^2)/R
This basically says that your power consumption, when put in terms of one variable for simplified analysis, increases with voltage. The squared term on voltage says that it not only increases, but increases at a rate of V^2, so for every 2V you increase your VV output battery, the power will increase 2^2 = 4W.

It also says that power will decrease by a factor of R, so you increase R and P decreases.
Ex: increase R from 1.8 Ohms to 2.5 Ohms P goes down to .7*P, or 30% less than whatever you started with.


Conclusion:

As you increase V, P increases by factor of V^2. As you decrease V, P decreases by factor of 1/(V^2).

As you increase R, P decreases by factor of 1/R. As you decrease R, P increases by factor of R.

Plug numbers into P = (V^2)/R in order to get some rough estimates of power consumption and heat.
I generally assume that coil temperature is a relatively linear function of Power(P), or that coil temperature change due to voltage or resistance change is closely approximated by change in Power(P).



Hope this helps someone! If nothing else I just solidified Ohms law in my own mind!

I looked at this and feel like i needed to know calculus to decipher what you just wrote lol.

I have been CIGARETTE-FREE for 24 freakin' hours. That seems so ridiculous to a non-smoker, to celebrate that, but I know there are plenty of folks on the forum who will know exactly how INCREDIBLE that is.

Some non-smokers do understand. When I started vaping exclusively, a non-smoker friend of mine gave me a 24 hour chip. I carry my chip around with me.

Haven't lit a cigarette, haven't even really wanted to. I didn't know that would EVER happen. I am totally amazed.

Me too. I love it.

I have an eGo-c Twist with a Vivi Nova tank (2.5 ohm, I think.) I am using juice bought from a local store. I have replacement wicks/coils on order as well as an extra battery and some juice that most folk say approximates Newports, my (ex-) drug of choice...for more than forty years!

Excellent. If you're able, visit some brick-and-mortar vape shops that offer juice sampling and try a lot of flavors. You might be surprised to discover you enjoy something you didn't imagine you would. I also recommend trying the same thing a couple of weeks in, a month or so in, etc. Your tastes will change somewhat as your body recovers from smoking.

Many of us enjoy one or more "tobacco" flavors, but I think most of us would also admit that none of them actually taste like "burning leaves and paper" because there are no burning leaves and paper involved. For this reason, I encourage people to pursue flavors they enjoy, whatever they might be, regardless whether they're called "tobacco," rather than chase the impossible flavor of burning leaves and paper. Your tastes will change soon enough anyway. You may find a "tobacco" flavor you like, but the flavor of actual burning tobacco will probably disgust you after a while.

first, what would be the difference in using a lower resistance coil, and second, when the hours on the battery are spec'd, does that mean amount of time on, or amount of time in actual use?

I think these have been pretty ably answered, but just to reiterate some basics...

If you battery was not variable voltage, I would usually recommend 1.8-2.2 ohm coils for an eGo-style battery. Since you have variable voltage, a much broader range can work just fine, because you can adjust to suit your tastes.

A lot of charts like this may be found floating around teh interwebz. They can be a handy guideline for folks starting out. At the same time, the "green zone" is not set in stone. Combining 1.8 ohms and 4 volts is almost 9 watts, sure; Ohm's law is not going to change. But 9 watts works well for some juices. Other juices would get nasty at 9 watts and you'd be much better off near 4.5 watts. So use the chart and your personal tastes as a guide.

As Jwaterski has said, battery life is subjective. How a store can state a certain battery will give you X amount of hours is just not right. It depends on to many factors to give a straight answer. The only way you'll know with what you have, is your switch will start to flash when the battery needs charging. So I agree, get a backup and then maybe a backup to your backup.

Yep. A lot of people will tell you that 650 mAh will last about 5-6 hours, 900 mAh will last about 8-9 hours, and so forth. But how you use the battery will also be a factor. Have a backup with you when you're out and about, and have a backup for your backup in case something gets lost or broken.

I do notice that today I have a bit of a sore throat on one side and vaping kind of burns afterward.

When I first started vaping, I was using convenience store disposables while waiting for my starter kit in the mail. Vaping those NJoys and Blus left me feeling like I had chemical burns on my tongue and throat. The nicotine level of those disposables (~24mg/mL or more) was just too high for me. I now vape <10mg all the time and I'm never comfortable above that.

I would not assume you have a problem with PG or VG yet. My first thoughts are:
1. You may need to drink more fluids when vaping. It's very dehydrating.
2. The wattage might be too high. When my wattage is a little too high, I sometimes feel scalded after. Adjust your voltage down a little.
3. The nicotine might be too high. When my nic is too high, I sometimes feel as if I have chemical burns. Try different levels of nicotine.

 

[madqatter]

I don't think I need more vapor then I have, but warmer would be more similar to the cigarette I am used to.

Bottom coil clearomizers, such as Kanger Evods and Protanks, tend to produce a cooler vapor. Top coil clearomizers tend to produce a warmer vapor. If memory serves, the Vivi Nova is a bottom coil clearomizer. You might want to experiment with some different juice attachments.

The first draw, when it's been sitting on its side, is the closest to what I'm looking for. Subsequent draws, not as much (but still good - no complaints.)

What is different about the first draw? More vapor? More flavor? If you can describe it, we might be able to help diagnose the issue.
