i am new to vaping, but thanks to vaping I am now 20 days off analog cigarettes and very happy. I am using an eleaf power nano which I am enjoying greatly. I use the ec .3 ohm coil in it because I realized very quickly I am much more comfortable with lung hitting. My question is with a couple coils I've had they consistently register at .27 and never change but recently I put in a new coil and it started out showing at .27 but after a couple hours of use it showed at .25 and now it's showing .23 on the screen. It's still working perfectly and even though it's rated at 30 watts minimum I'm running it at 25 watts because the flavor for the juice I'm using seems to really come out at 25 watts. It's a 70vg/30pg juice so vapor is really good. Is the change in the ohms it's displaying a normal thing or should I be concerned? It's really working well so that's why I'm confused because I've noticed no change in performance.

A new coil reading 2 or 3 hundredths of an ohm one way or the other is quite normal. A coil dropping resistance over time is kind of odd. The resistance can go up a bit as it's being used after a few days or more, but usually doesn't go down. I'd keep an eye on it.
Thanks for the reply for the last couple hours it's stayed at .23 and I've been vaping quite a bit, weird but it's working great so I'll just keep an eye on it
....and welcome to ECF. It's a pretty good group with lots of helpful and knowledgeable people. Congrats on getting off the cigs.
Thanks it was important for me to get off the cigs because it was found out I have a spot on my lung, so far appears to be no big deal but I decided not to push that envelope any further. I feel like it's a miracle I've been able to quit after 30+ years of smoking but thanks to the invention of ecigs I've been able to do it.
Yeah, it's better to quit sooner than later when it's too late. Vaping has helped a lot of people. It's too bad that the FDA is trying to put an end to it.
Yeah that's one thing I don't get, it's stupid to try and regulate ecigs so much but yet the real killers, meaning cigarettes and their manufacturers are able to get away with so much. I figure it's got to be just a money thing. Big tobacco companies bring in a lot of revenue and pay a lot to the government.
Yea, a lot of us at ECF are quite upset about that.. We've signed petitions, and done whatever we could, but through the years we've seen a lot of underhanded politics and blatantly exaggerated claims to get the approval the FDA wanted. I expect to see a lot of angry posts on this thread... I'll be the first to restrain.
And welcome to the forums!
Now, one quick possibility to your ecig question, is it might have to do with the heat of the atomizer. 1/100th of an ohm here or there is like the difference between a 250 horsepower engine and a 251 horsepower engine... you won't notice anything. if you start seeing a more drastic change, then you might want to consider looking in to it.. bt not at these levels.
just one question... any chance your juice could be a coil killer? that's one that has a lot of sweet/residue to build up on the coil. I can see plaquing and build up lowering your res.
Small Variation in Ohms like you are seeing is Normal. Just as you might Notice that when the Coil is Hot, the Ohms Increase. And then it falls back to a Room Temperature ohm amount as it cools.
BTW - You are Absolutely Right. It defies logic that the FDA wants to Regulate e-Cigarettes back to the Stone Age while at the Same Time, give Regular Cigarettes a Pass.
BTW2 - Way to Go on 21 Days Smoke Free!
BTW3 - Welcome to the ECF.
I'll have to +1 what zoiDman said. It's like that in everyday life too. Things are always "approximated". If it were electronics, then I'd be concerned. But Ecig coils aren't electronics, they're electric which goes by generalized ratings. Kind of like your wall outlet.. it says 110 volts, but it could give anywhere between 105-120 volts. Like your wall adapter, you shouldn't be concerned if it's not exact...but if your wall outlet was giving 80 volts, then I'd be concerned and call an electrician. With cars, If an engine was giving out 248 horsepower rather than the 250 horsepower it was rated for, there'd be no concern... but if it was giving out 200 horsepower, I'd take it to the mechanic.
The ohms has a few things to note however. First, with all coils, the ohms will go up over time as the coil gets used. It'll take a week before you notice ANY change, but it will go up over time if you keep using the same coil. That is why Variable Wattage became popular.. Using Ohms Law, it will vary the volltage depending on the current ohms of the coil to get the same vape.
The other thing to note, is Temperature control works on the Ohms varying in the coils. All coils vary in temperature slightly depending on what the coils are made of. Kanthal is an alloy (a mix) of Iron, Chromium, and aluminum. Because the percentages of the metals may vary slightly from one manufacturer to another, the ohms change ever so slightly depending on which kanthal you get. However, they all hardly change ohms at all and offer a fairly even level of resistance... but it does change slightly depending on heat.. but not enough to make any difference. Temperature control wire uses wire that varies the ohms as it gets hotter ona larger and more consistant rate. Stainless Steel, Nickel, and Titanium are used. Even though Stainless Steel is an alloy (mix of metals), it behaves on a similar rating if you get certain mixes (316L is a specific formula of iron and nickel Chromium, and other substances). NIckel and Titanium is pretty much as pure as they can get and are considered a "base metal"... it behaves on a very predictable manner depending on how warm/hot the wire is. So, as the temperature gets hotter, the ohms go up, and it knows by the difference in ohms how hot the wire is. This is how many digital thermometers work.
I vote neal as the science geek and teacher's pet! kidding!.. I seriously loved the way you explained it.
It may be a good idea to get yourself some backups and perhaps look into DIY ejuice. Who knows how things are going to end up and now that you (and us all) have found something that really works making sure your able to vape the way you want to is an investment worth looking into. Welcome to the forum!
those of us up north are hoping we'll go less the asinine FDA way and closer to the slightly more relaxed brit way...
My first "real" mod was the nano and I really do like it, but it really lacks in the battery life performance. I got an Eleaf Pico, an external nitecore battery charger and a couple 18650s and am so much happier with it. Or I was until I bricked it attempting to upgrade the firmware. Hoping I can get it back online myself, but if I can't I will return it for another one. Only slightly bigger than the nano with the convenience of changing batteries as needed.
Welcome and glad you joined.
To get you up to speed with ohms and the change thereof, might like to watch:
Variable Voltage versus Variable wattage
The youtube vid does not tell you why resistances change with the respect to a coil. Many factors can cause this, chef among them, corrosion a term for metal degradation brought on by temperature and environmental exposure. 1/2 ohm change is not out of the question depending on the build,longevity.environment etc..
What I think some of you are missing, his resistance is dropping, not rising from use or temperature.
Lol... it was a learning experience for me when I started vaping. I am one of those who dig deep into exactly what I am getting myself into.
You should've seen me looking for a new family van....
lol hubby and I trade off on who geeks out on what... vaping is my research pet project... and ewwww on vans, lol, suv or truck only for this household.
