Finally tamed the rba for Kanger SubTank Mini

[Uranium Willie]

I finally, FINALLY, got the rba on the Subtank Mink to produce vapor without the horrible side-effect of juice explosions!

Its a common problem, and i would post it in a more logical forum, BUT, if you are having trouble with the sonic booming of the wick/juice/coil, i have a solution.

After trying videos, forums, that annoying bro-ey-guy on youtube, variable adjustments and every other internet solution... i had a blind-hope epiphany of sorts...

0.4 Ohm microcoil made from 24 g. kanthal.

Cotton bacon wick (extra long and twisted to fit through coil), excess wick coiled as well and packed directly on to the rba deck before putting chimney on.

Precision flathead screwdriver to push the wick away from the coil's legs after wetting the wick with a few drops. On each side of the build, just push the wick away from your wire legs.

This works wonders. I think the twisted wick allows for more cotton to be added to the wick without clogging juice wells (no dry hits yet, at all). But also, i watched the coil fire with a juiced wick just to see what was happening, and it looked like the terminal posts were responsible for the sonic boom. Then i noticed the wick was touching the legs on both sides of the deck. Once i packed the wick on each side of the deck away from the coil's legs, the explosions ceased.

Good luck. I hope this helps with the frustration of rebuilding the Kanger STM (a great learning experience though).

Thanks for the info

How about a muffler?

I rarely get any spitting. I just wick with barely enough to touch the deck. basically cutting the wick even with the sides of the rba unit then tucking it down.

Also recently have been toying with pancake wicking to good effect.

I tried the pancake a few times and ended up with a burnt wick every one of em. Could be due to using cotton "bacon" material?

Twisting the cotton bacon, keeping the wick at least an inch or more on either side after passing through the coil, and then making the ends look as close to princess Leia's hair as i can (cinnamon buns) seems to do the trick for me.

I read that its good to keep the wick away from the sidewall, and improvised this to see how it would work.

i tend to use cotton bacon on my drippers and the japanese cotton in all my tank rba applications... i modded my kanger stm rba by drilling the sides - works like a champ

Interesting. I just rebuilt my RBA 3 times, trying different amounts of cotton, various ways of packing the cotton, etc...still getting small popping sounds, but great vape and flavor, without leakage, so I left it alone. Glad to know the issue is the terminals for my next build. Thanks a ton!
