Many on here vape higher wattage, and use RDA's with 3mg or 6mg nic and huff huge engulfing clouds. I have a Kanger subtank mini on a Smok Xpro m50. I currently have the RBA in it with a .5 ohm build. I vape happily at ~20 watts with 18mg nic. 3-4 hits and im good for a while. Clouds are ok, way more than say a clearo. Thoughts?
