I have seen pictures on ECF of someone dismantling a E2 ceramic cartomizer, disconnecting the power and ground, and attaching a regular 510 atty onto it. He did in fact get it to fire and it was working fine. I think it was 99% working, the main problem is that once you remove the "cartomizer atty", which is different than any ATTY out there, is the fact that when you put it all together, you do not get the same seal or tightness of where the cartomizer reaches the atty. So a lot of liquid was seeping through the line where the cartomizer is pushed up against the bottom of the atty.
He also had an issue when screwing it on, because he was twisting the cartomizer to screw it on, however he was turning the cartomizer housing, but the atty was staying in place, and by twisting it he disconnected the soldered wires. Since the housing of a cart is not rubber or silicon, you can't squeeze it tight to hold the atty while screwing it on...so that was 1 of his problems as well.
If you look at the E2 V4 custom cartomizers, I think they are very close to getting a full blown atty in there, and since it's see through you'll see how the mechanism works. Another problem is the atty would continue to stay flooded, and as you take your draw to vape, you're sucking out liquid too fast for the atomizer to burn so you're getting vape and liquid on each draw, plus leakage at the seam as mentioned above.
IMO, i think the knotted wick in the cartomizer is a huge reason the cartomizer can work, because it can work in a flooded scenario, where as a 510 atty, or any atty for that matter, if flooded, would spill
juice out through it's center hole.
I'm sure in 1 year we'll all be selling or throwing away all the hundreds and thousands of dollars we spent on digital
ecig Gear for some really sick stuff out there. For example, I saw a prototype of a 3.7v wetbox did not have a bottle for liquid, instead it had a glass section inside the box that contains the liquid, from there as you take a pull you're also drawing up liquid so it's instant liquid to atty, and atty to vapor. There was no need to push or feed the atty , it was just a constant flow of liquid every time you took a draw from it. Blew my mind !
Now imagine where we will be in a year from now...smoking analogs will be a thing of the past because of the digital age we're in. If smoking is digital, i'm sure in about 20 years, we'll figure out a way to make drinking digital and electronic also, lol
