Longevity issues with kanger dualcoils.

[daesania]

I've had the same exact set up for about a year and a half now. Itaste VTR + Aerotank with 1.5 ohm coils, and i vape at 9.0 watts. I tend to only vape one specific brand/flavor, I'm one of those weird people that just like one thing and stick with it. Up until July last year, i used a local vape shop's liquid. I liked it and it was fantastic. I'm a little fuzzy on their ratio, but I believe it was 70/30 pg/vg. Their liquid would never pool under the coil and my coils would last for over 5 weeks at a time. Then i moved. The cost of their liquid plus shipping was just too high, i was already paying 22 bucks for a 30 ml plus shipping on top of it was just killing my wallet. I found a couple other sources of liquid, one on the net being Apollo ecigs, and the other being local B&M selling VGOD liquid. Both of those i believe are 70/30 vg/pg.

Now since the switch to either of those 2 liquids, my coils are only lasting 5 days tops, and at nearly 2 dollars a pop, its killing my wallet even more than with the liquid i was having shipped here from that local store in FL. What is going on? Is that ratio of VG/PG killing my coils? Its not so much that the coils are burning out, but i just keep having to take a harder and harder draw as the days go on. When its a fresh coil, i get tons of flavor and good vapor, but towards day 4-5, flavor minimizes and vapor decreases. I've soaked them in distilled water and let them dry out, but even that the flavor/vapor tends to peter out after a day or so.

Thoughts?

Its not so much as vg/pg ratio, but sugar amount in the juice which will kill/clog up the coils faster, even if its similar flavor. Even if its same flavor but different brand, flavoring and juice sugar count will greatly vary from brand to brand of juice.

In my short term two week study; the more sugar a juice has, the faster the coils get fouled up vs juices with no sugar and are more tobacco based.

I my experience, White Label is a great juice brand and is cheap per ml.

Have you tried soaking the coils in PGA? Alc cuts coil gunk FAR better than water.

Any tips to help increase the usage of my coils? Dry burning perhaps? I tried doing some dry burning last night of my coil but man, it must have really been clogged up because even after 30+ 2-3 second firings, it was still producing a little bit of vapor and a few crackles.

Hmm, i have not. I'll have to hit up the store sometime this week to grab some to try.

Some people swear by sonic cleaners. If you have one you can try that. I use one and it seems to clean the gunk off.

I have tried various methods of cleaning the coils and dry burning them, and it only ruins the coil or you only gain a day worth of using the coil.

Dry burning coils only works for custom made coils for RDA or RTA. When you dry burn pre-made coil that you use, you end up burning the wicking material that adds more ash to juice and shortens life span of the coil.

You can try a boiling bath mix ( baking soda+ peroxide) then flushed with cool water, which will require a 24 hour drying period. But even then, its a 50/50 chance that a coil will work for a day or two.

Only other positive experience i had with, is to use a battery mod that has a much better voltage regulation (Sigelei or similar), so your coils dont get cooked do to a better chipset that is better at controlling the output voltage. For example; MVP2+ Apire Nautilus Mini only allowed me to vape at 9w with no dry hits. With Sig100+ Nautilus Mini i was able to vape at 13w.
