Coils Lasting 3 Days :(

[Acheron44]

Hi guys,

I picked up an Aerotank Mini the other day. Really like it, but my first coil needed replacing after just 3 days.
I used it for 2 days without cleaning, and on day 3 I took it apart, cleaned it out, put it back together and dry burned it. It was ok(ish) on this 3rd day but by the end of the night it was tasting pretty awful. So I again took it apart, cleaned it out, dry burned it and reassembled. No difference, was just tasting of burning.

I've watched videos how to dry burn so I don't THINK I'm overlooking it, but this is surely the most likely cause, right?

If so, should I be just soaking it in hot water for 15 mins then leaving it on kitchen towel overnight to dry out?

I'd really rather not have to mess around with alcohol or cleaning solutions or drying it with rice and all that. Really just want hassle free vaping including the cleaning procedure.

Also, how often should I be cleaning it out? I've been watching videos on rebuildable coils recently, and they're saying once a week - of course I'm not rebuilding but is there such a big difference in the frequency of cleaning between a standard and rebuilt coil?

I don't wanna have to change out coils every 2-4 days.

Thanks in advance!

Are you using dark juice? Dark juices will caramelize the coil, and wick. You may be able to rewick them, but as I don't have a nautalus, I don't know.
But for me, trouble free non rebuilding vaping is all about the cartotank.

Hey danca, thanks for the quick reply.

No I rarely use dark juice, but yeah on this occasion I used 2 light juices for the first couple days, and at the end of the 2nd day I tried a darker tobacco flavour juice.

I've got a Nautilus too, but this post is about the Kanger Aerotank Mini. I have heard that the Nautilus' coils are cooked after about 4 days, and my very knowledgable vape shop guy doesn't even stock or recommend them for that reason - so I'm just surprised this Kanger tank is behaving the same way.

Likely it's something I've done, but I'm still relatively new to this, and wanna learn to avoid wasting time and cash in future

Just to add, I've started researching rebuilding coils, and Kayfun's and Russians etc. I'll definitely get into RBA's, RDA's etc - once I learn! But for now I don't even know the differences (or exactly what the abbreviations mean entirely)

I know in EU, we had a bad bunch of coils a few months back. My girlfriend asked me to teach her how to coil them herself, and now she's pretty happy with the result. I do know for a fact you can rewick kangers, but that's still a lot to do at first. If you have a VV device, try lowering the voltage.

Not just dark liquids, also the sweeter the liquid is the faster it will muck up a coil.

The other thing that can contribute to a coil crudding up really fast is running it too hot. How do you start a new coil? The best approach is to start a new coil at your lowest available voltage/wattage setting and only move it up until you hit the flavor and vapor production you are looking for. Those charts with suggested settings are really a bad idea.

I'm in Scotland, so it could be bad coils but I'm more than likely to blame to be honest. I'm also after simplicity and with my Mini Novas I would wash them the same way and dry burn and they'd last 2 weeks per coil.

Tried lowering voltage right down, but same effect. I've changed the coil and it's fine now, like brand new, but of course I just don't wanna be updating this post in another 3 days :-/

That sounds like the experience we had. Might be worth asking the shop, to see if you're the only one or not. When we went in and spoke to them, they said they had a lot of people doing that lately. The lady even sweet talked a few free coils out of them. She's good like that.

Normally I'm starting off at 3.8v @ 9w, and pretty quickly moving up to my preferred 4.4v @ 10w, running the Aerotank Mini on an MVP2 & VV/V3.
I like sweet juices and they're light, but I like tobacco flavours too and they tend to be pretty dark. But I'd say 80% I'm using light colored juices.

Like danca was getting at it might just be a run of bad coils. I have noticed with the PT2 that some times you hit a coil that just seems to go yuck in short order. When dry burning I have also noticed I hit a lot of coils that have hot spots that shouldn't be there, usually at the outside edge of the coil where the legs are. A hot spot like that can really make a coil work like crap. I never really made the connection until now between lousy, short lived coils and those hot spots.

Ok that's great to know! I'll keep an eye on it, I've installed the spare you get in the Aerotank box, and after that I've got a pack of replacement coils, so fingers crossed I get some proper life out of those.

On a side note, how long are you dry burning after you've cleaned the parts?

I pulse them about 5 times or so. But do more if you want.

 

[Rickajho]

How I approach it with the PT2 coils is:

Take the vent tube off and put in in simmering water for a few minutes to get any "loose" liquid out.

Blow as much water out as I can. I happen to have a hair dryer with a "cup" of sorts on the end (they call it a diffuser) that I can just plonk some coils into and contain them in. Low speed, low heat for about three minutes to get the moisture out.

3.2 volts and I just pulse for about three seconds at a time until any smoke from burning residue stops coming off the coil and wick.

I'll drop it back in simmering water for another minute or two to get any ash from the dry burn out. Either force drying it again with the hair dryer or just leave them sit until dry.

The thing is when dry burning if you see a coil with those hot spots - glowing almost white hot while the rest of the coil is a nice, even orange - you know that coil isn't going to last long anyway. If I pop the coil on those when dry burning it never surprises me.

It somewhat defies explanation too. They are all built the same, but some of them have a problem like that.

That does sound strange! I'll definitely look more closely at my coils to see if this happens to me too.

Thanks for the detailed guide too. Every day you learn something new on here.

My experience is that some people have really poor performance with bottom coils. These coils tend to get quite hot, and if you hit it too many times in a row, you can easily dry them out and they are pretty much cooked at that point. I used to love Kanger bottom coil tanks, but I now find it pretty hard to recommend them for anything other than standard-voltage vaping.

 

[Acheron44]

Yeah I'm pretty bad for chain-vaping to be honest!

Are you rebuilding your own coils now?

Personally, I bought PT2 coils in bulk when I had a couple really good deals cross my path (places going out of business - stuff like that) so I never bothered with rebuilding. I really don't use then much any more either. But if you want to looking rebuilding you will want to head for this thread. I'm parking you right in the middle of it, with this really good explanation for how to rebuild a Kanger PT single coil. http://www.e-cigarette-forum.com/fo...20-kanger-protank-rebuild-33.html#post9844874

Well, here's the truth. The coil's on non-rebuildable's are hard to replace and only last a couple days, dry burning isn't exactly the way to go either. In my opinion if you vape daily and plan on vaping daily for more than a couple weeks, your going to want to buy a rebuildable tank atomizer or your just going to have to buy not just the coil but a new tank every time you go to get juice. Look into the kayfun lite or any other type of rebuildable tank atomizer.

I personally rebuild every 3rd refill and when I take the old coil/cotton out it's always already burnt.

Running that high on the wattage or voltage is likely the culprit. BTW, those devices only run on either the wattage or voltage settings, so whichever you set last is what you're running it on. I'm a watts man myself and I use about 7 watts for most of my Kanger builds and the coils last a long time.

Both the kayfun and Russian are awsome RBA 's imo. Once you start building you'll neva look back.[emoji2]
