Higher Resistance Coils For New Starter

[tj99959]

Hmmm, it kinda looks has though my battery may not be up to the job with the Aero?.... http://www.e-cigarette-forum.com/fo...t-enough-voltage-my-aerotank-clearomizer.html

I'm totally new to vaping and all I want is a very simple starter kit to see if its for me, hence my purchase of the Evod Glass. However, the vape temp is way too hot for me and is literally unuseable which is why I'm looking for an alternative tank to go with my pair of 650mah, 3.7v batteries.

At this stage I'm not looking at buying sets of VV batteries, building my own coils etc. I'm really not concerned about vapour production, throat hit is a bit of a so-so: all I want is to try an alternative nicotine delivery system - vaping - to see if I can get along with it. If I do, well the above is most likely to follow.

Your problem seems to be to hot. A bigger battery (more voltage) would only make it worse.
1.5 ohms @ 3,7v = 9 watts, and yes, I can easily see why a noob would think that's to hot.

The easy solution is to put a 2 ohm atomizer in your AeroTank.
Or buy one of those 75c cartomizers ($1.25 at most stores) that I suggested earlier, and see if they work better for you.

OR, since you don't like the clearomizer you have, by all means buy more clearomizers trying to find one that works.

you should try a 2.2 or 2.5 single coil first before you go a buy another tank.

I understand where you are coming from OP. When I got an eGo I wanted to see if it was viable to keep me off cigarettes. I found it was with my evod v1 tanks and the 1.8ohm heads - however everyone seems to find different things satisfying when it comes to vaping.
In my experience I've found it's cheaper to start out with a better battery that has some adjustablility to it. They will allow you to adjust your wattage for the heads that you have so you dont have to buy a crap ton of heads to find out what works best for you. You will likely end up trying a few different tanks until you nail one down that you like - one of the reason I recommend the aerotank/nautilus is you usually dont have to buy as many tanks because of the adjust able airflow. With something like an EVOD, or Protank2 or 3 you are stuck with the stock airflow unless you want to try drilling out the airflow or plugging it with tape or something.

But again, I understand you not wanting to spend a ton of money on devices that you may not find as a suitable replacement for your tobacco habit.
Do you have any good B&Ms in your area? maybe they will allow you to try heads at different resistances? If they have a tasting bar, maybe try some of those to see if they produce anything close to what you are looking for. Usually they use the cheapest clearomizers on there, but it will give you something to compare against your own rig.

Understanding how these things work may help you better understand why I'm saying this:
Mostly this revolves around Ohms Law. Wattage is power supplied to the coil, Resistance and Voltage are used to calculate the Wattage. More wattage means hotter vape. Just because you cant adjust the voltage doesn't mean you cant adjust the wattage as it is a function of the voltage and resistance. Being able to adjust the wattage or voltage on your device makes it easier as you don't have to swap out coils to get your target wattage. This also solves the inconsistency in manufactured heads - some times they are printed at 1.8ohm heads, but the actual resistance when tested on a meter is higher or lower than that. I've seen them off as much as .2ohms.
Airflow is another aspect that deals with the heat and density of your vape - more airflow can make for a cooler and thinner vape. opening the airflow may lead to dry hits though as the bottom coil clearomizers that are currently on the market are vacuum based - when you draw on the tank air is brought in to cool the coil and the negative pressure from the suction draws juice into the head - more airflow with the same draw would mean less negative pressure and thus, less juice drawn into the head. It's all about balance.

The cheapest route would be to buy a few heads with different resistances and try those out on your evod. See if those produce a vape you like - that would be about $3 a head.
You can try the cartomizer route. It is older technology, but many people still love their cartos/cartotanks. They can be a bit of a mess to deal with though - flooding, changing cartos, punching cartos, etc. You may also have a harder time troubleshooting your vape as there is more support for clearomizers.
If that doesnt get you something you like, you may want to try a different tank. Maybe try the ProTank3 (i think it takes the same heads as the evods, but has a wider airflow). I think you can also buy the AeroTank adjustable airflow piece and use it on the protank 3. I'm not sure about any of that though, so double check with some googling. As you mentioned though, that may not work as well as a ProTank2 because the source of the problem may be the dual coil heads.

The 1.8 will make a difference, But the 2.0-2.5 coils would be better for you, by the sound of it. These coils are available for your atomizer, same as those used on the PT3 and Aero and Gene. I would suggest you might be happier with one of the newer style clearos than the evod.

^^This. It;s been a while since I used mine, but put my Pro Tank 2 on an EVOD starter and it works great with 2.0 coils. Flavor is awesome compared to the EVOD tanks and 1.5 and 1.8 coils.

 

[Katya]

This explanation to me reads like the evod would be putting out a cool vapor with an anemic hit. From the OPs description this is not what sounds like they are experiencing.

A dual coil atty puts out a cooler vapor but more of it--compared to a single coil atty of the same resistance. That's why I asked the OP about the voltage he's using. Something doesn't add up--dual coils require more wattage than single coils of the same resistance.

Excellent advice and comments, and thank you.

I live in England and unfortunately where I'm sited I'm nowhere near a vape shop. That's what I really wanted so hopefully I could have tried out different kit to avoid all my current difficulties!

Anyway I've decided to go with my original option of the Protank 2 with 2.5 coils, although things are that tight at the minute even for 8GBP I wont be able to order it until the end of next week.

Fingers crossed, and cheers again!

Will be done!

A dual coil atty puts out a cooler vapor but more of it--compared to a single coil atty of the same resistance. That's why I asked the OP about the voltage he's using. Something doesn't add up--dual coils require more wattage than single coils of the same resistance.

Well I can only speak has I find and the vape temp is way too hot for me.

I'm not going to start chasing my tail spending loads of cash for something which in the end may not be for me, but I'm sure going to give it a go. I'll see how I get on with the Tank 2 - with which I'm a lot more hopeful - and take it from there, and many thanks for your time and advice too.

Sizzers said 3.7v:

Fixed voltage Evod battery x 2 @ 3.7V which was part of the starter kit.

Sizzers said 3.7v:

Thanks--I saw that post, but wasn't sure if this was the very battery the OP used with his eVod glass atties--I just wanted a confirmation. Something still is not right.

I don't own an eVod regulated battery myself, but 3.7v (if that's what that battery outputs) is, on paper, not enough for dual-coil atties. I have several DC Kanger tanks (1.5Ω, 1.8 and 2.0Ω) and the lowest voltage I use with them is 4v--which translates to 4.3 watts per coil (with a 1.5Ω DC atty--two 3.0Ω coils), which is close to unvapeable territory, at least for me.

So something is not right here. I just can't imagine how 4.3 watts can feel too hot.

Maybe you're missing a variable, like a 50/50 eliquid being used or length of their draw? As I've definitely had dual coils taste burnt (dry hits) at 3.7 with a 1.5ohm with a decently long draw and had to back them down, as while I think the dual coils are parallel and not series, 1.5ohm is still 1.5ohm and those two coils are in a very small space and wicking isn't their strongsuit.

Dual coils are configured in parallel--so the OP is dealing with two 3Ω coils.

Dry hits are possible with any atty--but that's not what I think about when I read that the vape is too hot. Maybe I misunderstood the OP--if he meant dry hits, yes, those can be nasty and can happen with any coil at any wattage--if the wicking is poor, for whatever reason, and the coil is not resupplied with enough eliquid to vaporize.

Kanger recommends 5-7.5 watts per single coil for their atties. And my observations confirm that. Those atties can't wick fast enough (and there's not enough airflow) for comfortable vaping above 8-9 watts.

Hmmm... Was it too hot or were you getting dry hits? If dry hits--that's a different conversation altogether--see my post above.

Either way, for a 3.7v battery, you should stick with single coil atties, 1.8-2.2Ω coils are ideal.

It's still not clear to me if you're getting burning tastes and additional harshness, or just have a sensitive throat. I'm very sensitive to burning and have found some of the combinations that others deem fine burn too easily for me. I like variable voltage and often run right at the low limit.

If you have a sensitive throat, it may help to let in some air around the mouthpiece. This cools the vapor and increases turbulence and condensation, increasing flavor. If you can stop smoking your throat will improve. One thing is it may feel like it's hurting from the first second, but not increase like when something's actually hurting you. Also try lower nicotine and avoid flavors that add to the throat hit.
