Dual coil cartomizers

[Dmorr123]

Hello all. I'm a noobie just starting to vape after smoking for 14 years and I have a couple questions. I just recently got and ego-t and was hearing about a dual coil carto that would work. My question is. How does a dual coil match up against a LR ego atty? Has anyone tried them both? Does one give warmer vapor then the other or does one give more flavor and TH then the other. The reason I'm asking is cause I have the LR atty for the ego-t and didn't want to waste money on the dual coil. Thanks

 

[permafrying]

cant say how they match up but can tell you you won't be wasting your money these things are awesome!

 

[Dmorr123]

Since they are so cheap I think I will try some out. Thanks

They are fantastic but there are warnings about pairing them up with an Ego battery. The possibility of damaging the battery is the reason. The MOSFET specifically. I've tried it with an Ego briefly and it worked fine but over a longer period of time, it may do damage.

The LR atty gets hot fast. The dual coil cartos do not get hot near as fast.

The cartos deliver a lot of vapor and a good TH, but if you vape like you smoke a cigarette you will start getting the dry carto taste fairly quickly. (in my experience with them)

Seems like they are good if you only take a couple draws a minute.

I would try them out and see for yourself. My experience may not be typical.

Have you tried plain Boge LR 2.0ohm cartos? Those are probably hot enough for most people. What are the ohms of your atty?

Those dual coils are 1.5ohm and that is lower than many people will go with Ego.

I've been using 1.5 ohm dual coils from Madvapes on an eGo for a week and the setup is working great. I've used LR atties only on eGos for over a year and have never lost a battery (well I did lose a battery, but that has nothing to do with the LR atty!) The dual coils are the closest thing to an LR atty at 3.7V or less that I've tried yet. No other regular or LR carto has ever been close, but these are. They are a little better at true 3.7V than they are on the eGo, but I've found that by the second and third hit on the eGo they get nice and warm.

Thanks for the great advice. I did purchase some dual coils but I ordered the wrong ohms. I ordered the 1.25 and not the 1.5ohm. I did try one on my ego for just a little to see how they were and I was happy. I’m just not going to do it again after what I have read. At what voltage would the 1.25 be best to use at without running the risk of damaging something? I just ordered a maxi roughstack from madvapes and I can’t wait to get that in my hands. I’m going to order some of those 2.0ohm cartos that Dormouse recommend and see if I like them. Again thanks for all the advice. This forum is great!!!

1.25 is pushing very hard.
1.5 is pushing, but works even on standard 510 batteries (I use em exclusively on standard batteries).
Why an e-go would suffer, is beyond me if a regular batt can take it..Any time you run low ohm, you lessen charge time, as well as (over time) shorten the battery life.

Make sure you get adequate juice in em (~70 drops or so) and let them sit long before firing em off. Let em saturate.
Also remember the top coil is 1/3 into the carto, so if you run the fluid low, the top coil gets exposed and can burn.
Keep em moist.

But the duallies are dynamite.

Without getting supertechnical, why do these damage the MOSFET? I've found one supplier that recommends using these on EGOs and another that warns against it (for the same reason you gave). Funny, but the one recommending using them on Egos warns against using them on 510 batteries.

 

[PoliticallyIncorrect]

If by eGo atty you mean using a 510 atty with a cartridge, there's no comparison—DC wins hands down. If you're dripping with the 510, that's more complicated.

Think of dual cartos this way:

A 1.5 ohm dual carto is very similar to what you would get if your PV had two connectors on it... and you had double barreled 3.0 ohm cartos on it.

That's why it is not as hot (like an LR). Also why it takes twice the current. Also why there are mosfet warnings.

Dual coils are fantastic as long as you DON'T USE THEM ON AN EGO BATTERY. The pull too much voltage and will eventually destroy your battery.

It's an "Ohms Law" thing. Without getting technical.... it draws more electrons per second. That makes the circuits inside hotter. Ever use a real long extension cord on a high-draw device (like an electric heater?). Bad idea. It gets hot. That's why longer extension cords are usually thicker or rated for less current. The friction (resistance) builds up.... like rubbing your hands together on a cold day. Rub slow, not much heat. Rub fast.... warm.

Any given wire, or whole circuit, can only take so many electrons per second. Go beyond that, and it's an issue. Low Ohms = low resistance = higher drain = hotter electronics = higher stress

Now... to be fair... I don't suggest (as a general rule) less than 2.0 ohms. But YMMV. Some people swear by 1.5 ohm LR atties. They use them. They may just "risk it".....

Also, devices vary, and the manufacturers may make revisions and we don't even know it. So it could depend on your exact make/model of PV. To risk, or not to risk, that is the question! (forgive me Shakespeare!)

 

[Pav]

Thanks AP. Sounds like just more internal stress on the MOSFET of an Ego type battery. I also just found another supplier warning against it with Ego batts, and 510 batts.

What I find funny.... 1.5 ohms is 1.5 ohms. The carto is a "black box"... doesn't matter how many coils are inside for the amps (you may not even know... 1, 2, 500) if it's 1.5 ohms, that's what it consumes! It's the ohms that count.

Do they have warnings on single-coil 1.5 ohm cartos and atties as well as 1.5 ohm DCs? Or is it just the 1.25 ohm DC?

I was just checking my LR single and dual coils with the multimeter and the dual coil is working at 1.9 and the single is 2.6. The dual is supposed to be 1.5 to 2.0 so that's within range and the single is supposed to be 2.0. I am using these on my 1000 maH ego and the 2.0 single coil definitely produces more vapor and just a better all around hit while the dual coil feels like a monster rip it produces little vapor and a really syrupy taste until it warms up a bit then gives a decent hit, just nothing to write home about.

Ok. So it's not really even related to the number of coils, just low resistance.

Do they have warnings on single-coil 1.5 ohm cartos and atties as well as 1.5 ohm DCs? Or is it just the 1.25 ohm DC?

I don't know about 1.5ohm single coil. Does anyone make those? I'm seeing the warning for 1.5 and 1.25 ohm DCs.

I usually use 2.0 ohm LR single coil and am now trying 1.5 ohm dual coils on an Ego. No problems so far and it works really well, but I'm worried from these warnings about long term damage to my batts. Don' want to kill em all!

 

[earthpig]

Robby.
Zero the meter and add in the factor of meter leads having a resistance, (if you haven't already).
My meter has a .3ohm rating on the leads that needs subtracted from the measured reading.

That's probably true. I don't even own a voltage meter or whatever you call it. I use them on one of my ego batteries, my oldest one and I really like it. Love how much juice they hold and the vape with it. I'll see if this battery dies faster than the other battery that I purchased at the same time.
