A non-leaking tank is WAY harder than subohm!

At least teach a noob just what the benefits of using lower ohms in the head are. So many partial explanations are being passed around it's really a challenge to sift the diamonds out of the flour.

Personally I'm somewhat below the 1 ohm level. BUT, that's because I've learned the skill before the recent alternatives emerged. I'm a bit too lazy to learn something new when this works for me and I feel I know what I'm doing. If I was to learn something from the start right now, I'd go for the microcoils. From what people say, they give the same, if not better vaping experience than the traditional low-res setups. And, they supposedly work very well at quite a lot higher resistances.

There's vaping for the sake of nicotine delivery without quitting the hand-mouth habit. And there's what I call competition style vaping. Which I personally don't care about.

That being said, I will probably look more into microcoils when the outdoor season don't take up all my hobby time.

Great, finally something we can work with! I sure wish we had a ton more information about this. The facebook post reads like most of people's "scared straight" type posts but is really short on details of what actually happened.

Oh and look, the original poster works for a company that just happens to produce mech fuses ... color me surprised. And she didn't miss the opportunity to post her company's product.

Wouldn't surprise me if these occurred under "research conditions."

Dissing the messenger again, I see.

I'm probably not the right guy to do that, not needing less than 2 ohms to get a good vape at mid range voltages. Someone who's actually involved in it and has done the math might be better suited. I do wish that person would start the thread, though. There's no reason for someone to experience a runaway because no one told them how to do it right.

If it becomes popular, mods will arise with the correct safety devices to reduce the danger. From the description of those who do it, it sounds like the vapor is much tastier at sub ohm levels. It's why they do it. 5v at 2 ohms gives you a 12.5W vape at 2.5A. It's just not a good vape for me at that level using standardized atomizers.

Sub ohm vapers say the world changes with a point something coil at standard 3.7v levels and if you tried it you wouldn't go back. I don't care to try it because of the battery limitations.

There are plenty of resources on ECF for those who want to learn about sub ohm vaping. Here's one.

Dave, when I first discovered the joys of 5v vaping, I was enthralled. I went so far as to use 5v batts in nearly all my puny 3.7v devices (still do... when I use them). Like you, 5v at 2Ω is just too hot for my taste. I've found my own little sweet spot corner of the world whether it be at 5v or vaping on a DNA 20 (which, by the way, is rarely even set at or near 10 watts...7 or 8 is just dandy. ).

WattWick, SLR vapers abound in my area. It's been mentioned a few times now that the SoCal area is FILLED to the brim with a new community of SLR'ers. They love it, live for it, and yes, it definitely has become a competitive sport. The last 2 vape meets I attended were crowned with the BIGGEST CLOUD contest. It is fascinating to watch, but...

I can make comment on the experience of low ohm vapes. Allow me to be the first (am I the first? dunno) to say that I HAVE tried SLR vaping, many times now. I do not like it. Yes, imagine that. I don't like it at all. The flavor takes a back seat to the enormous rush of airy vapor hitting your little lungs. It's also a speed demon activity. Forget about long relaxing hits. Not for me, but I made an effort to see what all the hullabaloo was about. I opted out and put myself on the DoNotVapeThat list.

Thanks Bad, and my tanks don't leak either! http://www.e-cigarette-forum.com/forum/blogs/baditude/3710-5-cartomizer-tank-setup.html

Haha so there actually IS competition style vaping. Thought it was all in my head. I will admit to coiling at 0.8 ohms. But, as an experiment, I coiled one at 1 ohm. I'm still happy with it. I'm well used to very much more powerful and fragile batteries from other interests, so I might know more about staying within safe limits than the folks who get their first hands-on experience through vaping.

It's part about liking the lower resistances, part about finding it easier to coil with fewer coils and/or thicker wire. But, if one don't know what one is doing, it's also easier to blow oneself up doing so.

I'm not at all an expert. I do believe I know enough to keep myself safe, tho. *Knock on wood*

 

[Lessifer]

I think the benefits of sub ohm vaping, when using a thicker wire, is that you get a good amount of coil to wick area and can hit it with a higher wattage producing more heat. I've taken the other route to this same effect with micro coils, using a 1.3ohm coil of 28g that ends up being almost 1/3" solid tube of wire I get a very flavorful vape that produces more vapor than any regular coils I've tried. I don't think I'd win any competitions but it keeps me satisfied.

 

[Katdarling]

I like to try a vape on a micro coil. Primarily because I think they're cute.

1 ohm across a 3.7v battery produces 3.7A current. That's 13.7 watts. Why is any more than that not like plugging your iron, your toaster, and your hairdryer into an outlet and bypassing the breaker to allow it to happen? It's asking for trouble, IMO. Mods cut off at 3.5A for a reason.

The objective of life is to live long and healthy and with all your sensory organs and appendages intact. Anything that heats up next to my eyes will be as safe as possible. And in my pocket ... I don't want a bottle rocket. There also won't be any bypassed circuit breakers in my home.

UL is a pain sometimes, but they try to keep us from hurting ourselves.

My batteries are rated to 20a and I'm pulling barely 8a though them, how is that pushing anything?

Your numbers mean absolutely nothing, it's not like 3.5a is some kind of magical safety limit.

I should try it, but I probably won't. 8A is 8 amps of current flow no matter how it's derived. An 800 watt hair dryer is in that range at 120v. Not a good comparison, but a valid one. If you compared it to a car cigarette lighter you'd be pulling almost the same current(typically 10A @ 12V). Lots of heat.

I'm just having fun, FWIW, Stoned Penguin. Vaping below 2 ohms just isn't for me.

I can relate, DaveP. I build my coils @ 2 ohm too. I'm pulling more than adequate vapor with these on my AGA-T2's, sometimes to the point of eliciting laughter from me. Flavor is great. I'm into a cooler vape. I don't care for the old-school heat of an analog. I believe if you make a quality coil and wick build, it doesn't matter what resistance you use.

I haven't tried or even investigated micro coils yet. The store manager of my B&M showed me his first micro coil wrap on his RDA a couple of weeks ago; first one I've seen in person and I didn't try it.

I didn't do the amount of research I should have and got a magnum rev2 and I've had nothing but problems and I believe it's the batterysg

I vape 2 ohm up to 3 ohm cartos, tank heads, and such. I never get above 4.5v and usually stay in the range of 3.7v to 4.2v. When I find a juice that doesn't taste just right in a tank, I put it into a carto and life is good. I'm vaping some Hangsen Tobacco in a carto that tasted a little green in my Protank.

BTW, I live about 5 miles from Stormy's Vapor Cellar's new B&M store. They moved their inventory this past weekend and plan to open to the public on the 24th of August. I'm looking forward to actually seeing things before I mail order them. I'm sure they will have many cool items for me to browse through. This will be the first time that I will be able to actually do business in person instead of mail order. Most all the B&M stores in Ga are in the Atlanta area or farther North.

Can't argue 8 amps being 8 amps. But, unless you touch those wires to your body and push the button, amperage itself won't do you any harm. On the other hand, batteries not made to handle the stress might harm you. On the third hand, vapers should not use batteries that blow up or catch fire if stressed anyway... or that can't handle the stress in the first place.

There are things to consider in regards to heat/watts. Thicker coils require more watts to heat up, yet give a bigger surface area. Bigger surface area means more juice is boiled, meaning you have more liquid cooling. The wicks used for this is often SS mesh, which acts as a heat sink. To effectively remedy this, higher wattage is required. That leaves you with two options (that I know of). Lowering resistance to pull more amps, or pull more amps to power a buck boost circuit to up the voltage. The latter being what regulated or VV/VW mods do.

So, yes, it is a lot of heat. But that heat goes toward boiling more juice, not making anything any hotter. Juice can only get so hot before boiling and becoming vapor. That being said; with the heat sinking of SS mesh, the whole assembly gets hotter. Thus the vapor gets heated on its way to your mouth.

I'm not lobbying lowering ones resistance. Just trying to shed some light on the subject. Vape as thou wilt

I thought this was a safer alternative to analogs - now I gotta worry about my face detaching from my neck or by brain draining from my ears. I was saving my brains for the zombies - God help me -I am so scared and confused.....

 

[IrishUpstart]

Lol....I can understand that. I kinda checked out of my own thread due to nightmares.

 

[bluecat]

Lol....I can understand that. I kinda checked out of my own thread due to nightmares.

They way I look at is know the risks and learn how to minimize them. Which you are doing with this thread. Follow the advice that those with more experience have. Ask questions. In 50 years the only dumb question is that which is not asked.

I have jumped out of airpalne, but learned how first. I have jumped off a couple bridges with only a big rubber band around my ankles. Can't say I learned how first, just listened what the dudes said. After the second bridge I felt I tempted life too much and told everyone else I would keep the beer cold for them on the next jumps.

I for one am glad u made the thread and make it a daily reading. I am on the 2nd charge cycle on my batteries. They came off - an hour after- at 4.21 flickering to 4.22 and it made me worry. It maybe my multimeter. In the morning they were a nice 4.2. I'll just keep monitoring them. I don't think I need to worry yet. I am using panasonic pds in a svd.

 

[damthisisfun]

Let me ask this - Li On batteries are not a good choice? That is all i have - like 10 of em - 18650s and 18350s - for my SVD and Vamo V2.......

edit - what i have is

Panasonic CGR18650CH Rechargeable 2250mAh 3.7V 18650 Lithium Batteries

ICR18350 18350 3.7V "900mAh" Rechargeable Lithium Battery

are these "safer"
