Smoktech Dual Coil Cartomizers

[SteelJan]

I got some clear dual-coils from madvapes last week and am trying them, with the madvapes spearmint juice which is clear. On the first one, I quickly realized that I have to keep topping-off the juice to keep that upper coil wet, otherwise it starts browning the filler. On the second one, no matter if I kept the juice topped-off, the bottom one was scorching. I took it apart and saw that the sleeving that is supposed to cover each coil, was not covering the bottom coil and therefore letting it directly scorch the filler, a manufacturing flaw, okay, no biggie. I'm now on the 3rd one, seems these start drawing harder and harder until it's like sucking a stick in just a couple of days or so of usage.

Haven't tried cleaning and reusing one yet. Will do that and maybe do a vid on this thing.

Thanks for the tip on the Indy shop, will check that out.

Thanks! Did a review on these bad boys as well:

Hi, I just watched your review comparing the cartos. I currently use Boge lr's, and I have ordered the dual coil cartos. I have read about concerns using them on an eGo, and I noted that you used yours on an eGo. Have they been kind to your batt? Do you still like tham as much as you did last month? I have been sort of warned not to use them because they may kill the mofset switch. Have you had any problems?

The filler seems to swell quicker with juices that have alcohol based flavorings. I can plug one up in a couple of days with TopVapor Caramel tobacco, but I get five to seven days with something like BWB Maple Tobacco. - The nice thing is that one starts to plug up, you can just give it more voltage to get some performance back.

Yea.. I was about 4 days in when the one I destroyed for the review started tasting bad. It had a lifetime of about 20ml- all on one menthol juice.

Edit: I like these. But for particular juices (taste issue). But in general they are win.

Might be the fact that I vape the 1.5s at 5 volts. . . Guess that's why I'm not noticing the draw get tighter till after a week or so and I vape over 6ml a day. Are most of y'all vapin on egos @3.2 volts or mods?

 

[salemgold]

I use mine on my Buzz at 4.2V and use the same carto for about a week and 1/2. My husband uses his Buzz at about 3.7V and gets about 2 weeks with his peppermint in it. I have a friend that is using her Buzz at 3.7V with a DIY coffee flavor in it and has been using the same carto for 20 days

The clear ones are very simple to pull apart unwrap the filler wash with hot water also wash the coils with hot water and these things are perfectly clean again. Dry them off by patting the filler with paper towel hit coil with the hairdryer and roll everything back up and put back in the clear tube, done deal. I let mine sit for one day refill and they work like new. There was one small tiny black mark on the filler and it washed right off by the way, everything was white and like new again.

5.0v megladon batts in my rough stack. -- in fact, madvapes just started carrying the batteries but won't have a charger for them for a couple more weeks(lucky thing I already have chargers). Great price on the batts.

When the draw tightens up, I switch to 6.0v. I can fill them another couple of times or more.

 

[earthpig]

Don't know about the clear ones but I've been running a dualie now for 5 weeks and probably 150ml of fluid. It's getting tighter in draw but the vapor is still quite good.
Running on a standard 510 battery. It will never scorch, and these carto's just don't seem to burn unless run dry.

All juice dependent.
I'm using Johnson Creek Tenn Cured in VG.

Pretty decent lifespan across the board it looks like

I've been using my dual-coil for a month now, blasting it with 5v throughout the day.

They have come out with 306 dual coils.

so dual coil cart doesn't work w/ the ego ? then what it'll work with ?

The DC's do work on an ego. It just isn't recommended. - There are a couple of reasons not to use LR stuff on eGos. One is the heat generated by pulling the extra amps. It's tough on MOFSETs and is therefore a risk to the circuitry. That is probably a legitimate concern but can be mitigated somewhat by not chainvaping too much and letting it cool down.

The other reason really doesn't apply all that well to the DCs because they are a very low risk of shorting. LR atty failure is often a short. A short will take out a MOFSET easily. The DCs are not likely to blow a coil on a 3.2v regulated battery, so I just can't see that as a serious concern.

There are other reasons like the fact LR stuff drains the battery faster so it will go through more charge cycles in a shorter amount of time and therefore wear out quicker. Batteries don't last forever, so I don't look at that as a serious concern either.

You might wreck an eGo batt using the DCs, but you might wreck your car backing out of the garage too.

Seems to be quite a few people using them on Ego bats, and no one has reported killing a battery with them yet. Technically though, it could be hard on the battery.

Yes they have...
It took me one search and less than 15 seconds to find several reports. Here's a few at MadVapes....see reviews near the bottom of the page.

Low Resistance Refillable 510 Cartomizers 1.7 ohm

Try them on an eGo battery if you really want...but they're awfully wimpy when this underpowered.

One can get a better performing carto better in the voltages/C Rating limits of an eGo or 510 mini/mega battery...that will not drain your battery so fast and waste so much juice for less money.

If you don't have a High Drain battery that holds a good constant 3.7v under load...these cartos are nothing special. Might as well stick with a single coil. The SmokTech single coil in the same package is not bad for the money....and there's a slew of really nice cartos out there designed SPECIFICALLY FOR eGo and 510 mini batteries.

If ya got the battery and switch for the Dualies...they're right nice, definately a different experience...but I wouldn't toss out all the others just yet....

 

[earthpig]

I've been told repeatedly not to use em on a standard 510 battery as well. I have been for nearly 6 weeks and the shorty battery is showing some degradation (as expected) but still working. I fired off another one on a longer one, and works fine as well.

Whats a battery cost? My 510 cig sized are $9-12.oo ea. The cost of 8 to 10 regular carto's, or 1 1/2 packs of cigs. . No biggie to experiment. Bank won't get broken compared to smoking.

What does your face cost when one decides to blow up on you?

IF you want to continue taking these kinds of risks for such wimpy performance....it's your money, and your face.

It'd be irresponsibe not to warn folks not to do this....

If you insist on only using mini batteries...you'll get better performance from a regular carto anyways...but it's your money, and your face. Enjoy. Just don't sue anyone later because they didn't give the dualies special threads/batteries that won't fit anything else...and big fat warning signs that you have to break off before using.

If you'd like to get a better idea of what a dualie is like when properly powered using your 510 batteries try this:

Screw 2 regular 510 cartomizers on 2 regular 510 batteries loaded with the same juice.
Draw on them both at the same time.....
There ya go

It will probably work, just not very well. Essentially, the way these work, the stress on your battery would be similar to attaching two 3 Ohm cartomizers to the same battery. This means it draws at least twice the amperage from the battery each time you push the button. While eGo batteries have some safety stops to prevent an explosion...you will run the risk of blowing that safety switch, cooking the on/off gate/switch itself, or having a battery explosion. Also consider the voltage of an eGo battery under load is around 3.4v on average....while it's enough to get a little bit of vape from a dualie...it's going to be very 'cool' and 'whimpy'.

So....what can you use them with?

You'll want a mod that takes a high drain 3.7v protected battery (or safe chemistry battery), and has a switch rated at at least 2 amps (I'd recommend a 3amp or higher switch if possible).

SmokTech, the makers of this carto, offers an inexpensive modular regulated 3.7v unit called the E-power that is a decent match for these cartos and is less than $50 for a kit with 2 batteries (14500 I believe) and a charger. While I recommend a little better battery than what comes with the kit...these are certianly enough to get you started. The switch and regulator in these are just enough to get by on the dualies (and plenty for most any other carto/atty you want to use)...and are easily replaceable for a moderate price should you happen to blow one. E-power looks like an eGo battery...cone and all...but is slightly larger. There is talk that they have plans to offer more bits that can be screwed on in the future (like VV circuits, voltage meters, etc.), and even if those never come to fruit...it's already worth $50 just like it is

Other inexpensive tube and box mods abound...
RoughStack Maxi V2 for 18650 batteries (or stack smaller ones for 5/6v) can certianly deal with it...but is not a 'regulated' mod. These run about $50 not counting batteries and chargers.

Finally, here's a fun site that lists many of the mods that are out there...

The quality control on these Smok Tech dual coils is crap.

I order some from vaping zone, and from all the positive reviews i was expecting good things....

The batch i got (i've tried 3 at this point) way less vapor, less taste, and longer warm ups then standard 2.0 single coil carta's. Wasted way to much juice on these damned things, i'm throwing out 7 of them and considering it a lesson learned.

See this thread from someone with very similar experiences.
