after vaping an 18650 E-power for a couple weeks, I found I love the hit, vapor production and flavor but is a little large to be carrying around in my uniform pocket at work (Won't fit) So I decided to get an 14650 NoEgo and the NoEgo to Ego-t adapter to use the EMDCC on and look like one unit. Should be great! I love the 18650 with the EMDCC but have to use an 510 extender on it...looks funny
