My mom has an e-cab and she really likes it (not for me, I'm currently saving up for a Provari baby!!!) Anyway I was looking for some type of upgrade to her tank and haven't had much luck. I thought egos all had the same connection so I sent her a couple Vision Egos I was using on my ego-c but those didn't fit her battery. We are having a hard time figuring out if there is an adapter she needs like a 510 to ego or what. I read somewhere that the e-cab is smaller than a 510, anyone know what type of adapter we need or if there is another tank option for these things. Greatly appreciate the help!
