Simple method for wicking the Subtank Mini RBA

[DCBD]

After spending countless weeks watching Youtube videos and reading forum posts everywhere, I couldn't find a reliable method of wicking the Subtank Mini rba. Some would fail right away, some would be OK for a day or two, then start burning, leaking or getting dry hits. Then I stumbled upon this Youtube video.

The video lasts a whole 2 minutes. No talking head rambling, no wicking theories about juice and wick physics and most importantly, not a complicated method of shaping the wick a certain way, combing or fluffing the cotton that is complicated, that takes a lot of effort or practice. Just a simple, 2 minute how-to video about how to wick a Subtank Mini rba. Quite honestly, I thought it was too simple to really work. So I tried it and so far (after two days) it's been working better than any other method I've tried. I haven't had a single problem. It's worked flawlessly.

So if you are having wicking problems with the Subtank Mini RBA, it's worth the 2 minute time investment to watch the video and another 2 minutes to try it. It helped me and it just might help you.

Glad that is working for you. I just want to share what has worked for me as well. Happy Vaping!!!

I took an diamond cutoff wheel and enlarged the two notches where the juice feeds on both my sub tank rba's and have had no problems with dry hits since. It was a risky gamble not knowing if I would ruin them but it payed off. (This time) . I would not recommend this for the average novice,as you can easily render the rba useless. Having said that, no flooding, no dry hits. And not so finicky on how I wick now.

Forgot to mention, used a dremel tool.

Glad that's working for you. These tanks should have been designed with bigger openings so that more juice could get into the wicks. We have different methods but both methods are achieving the same thing, more juice getting to the wicks.

I don't have a problem with the way the RBA is designed. I continue to use the wicking method that I started this thread with and still have had no dry hits or flooding, it's been quick, easy and flawless. One key difference for problems could be different coil builds, power settings and juice ratios. I vape juices from 50/50 to 80VG, 6mg. My coil builds are 2.5mm ID, 2 wire twisted 28G kanthal, 5 wraps regular, that come out to ~0.7 ohms. For high VG juices, I get plenty of vapor/flavor at 11W and for 50/50 juices I rarely go above 14W. Of course vaping at over 20W, you're right, the smaller openings may have trouble keeping with the juice demand. For me, they are just right.
