Hey
@z man let me make sure I understand. I think what you are saying is that you broke the internal tank of the eVic AIO and want to know if you use the adapter can you put a normal 510 tank on the top?
If I got it right, then the answer is "maybe". If you still have the metal base of the broken tank, then yes, it will work, if not then no it won't. The base is absolutely necessary to properly use the adapter. Without the base, then the adapter is too short and you can't complete the circuit. TBH, I haven't even tried the internal tank in mine, mostly because I use build decks in all my gear, and I don't have the rebuildable coil for the AIO/Cubis. I'm hoping to get my hands on one someday so I can try it out, but for the moment it's untested.
I hope this answers your question, if not, then please clarify and I will try and give you a better answer.
HTH!
