I have been seeing a lot of people talk and vendors sell CE2 CE4 CE6 and so on yet I can't seem to find any information on what the CE stands for or what is the difference between the numbers behind CE.
CE stands for Cleotis Edwards
Rumor has it he is the chinese man that invented the cleromiser.....
Cleotis Edwards...well that's interesting...learn something new everyday.
I am not 100% sure on what the CE part stands for - just assumed it was the initials for clearomizer - hopefully some others know. The numbers however denote the version of the atomizer - as they version up. I never used a CE3 so i am not sure what the differences are between the CE3 and 4 but I know the 5 was when it became an atomizer you could take apart to clean it and replace the head as needed.
I know there were other slight design and coil changes, some very small, as you go up in numbers and one number (9 perhaps?) has a dual coil instead of a single one.
There are many video's on YouTube with reviews and how to's on CE's of all numbers where the intricacies and differences are discussed and demo'ed, and well reviewed on how they work and the different experiences one can get from one to another. Just searching there for CE4, CE5 and so on will get you a long list of videos you can watch about them.
Maybe it means Clearomizer Edition #
The first ce cartomizer was called the ce2 and it simply stands for cartomizer edition 2. It was the first cartomizer without poly fill. Each additional number added afterwards is merely a revision on the original design.
CE2/CE3 - There's not much going on here. CE2 is top coil, CE3 is bottom coil. Only hold 1 mil of juice, though some manufacturers offer them in larger capacity. I've never used either, because I've heard the new CE2's aren't very good and I hate using a syringe to fill anything so the CE3 is right out.
CE4 - The eGo clearomizer, often re-branded. The Volt X2 clearo is a CE4, as are the Crystal Vision cartos at NHaler and the I-Turbos at other vendors. And on and on and on... 1.4 ml capacity, more or less. They're not easily rebuildable, if at all. The original ones were press-fit together, but I've heard some manufacterers actually glue the whole thing together now.
CE4+, V2, V3, CE5 - Same design as the CE4, only the heads are replaceable in the same manner as the Vivi Nova. They can be rebuilt the same way, too.
CE5 (6-9) - ??? ...Profit! Mountain Oak Vapor, I think, has what they call a "wickless" CE5. If you're familiar with the Vision Nano, it's very similar on a larger scale. No visible wicks, solid tube with 1 or 2 holes in it with the wick and coil inside.
Keep in mind, most of this is based on observation only. I've only ever used the CE4/CE4+(++) models, and there is a ridiculous amount of vendor and manufacturer confusion when it comes to anything above the CE3. And some even attempt to obfuscate the older CE2/CE3 models.
Just to note, I did not write this, It was something that I copied and pasted a while back. i Copy stuff to a file that I find educational for me. Author was Jonnieprice. Thanks to Jonnie.
It's actually a Very Simple Numbering System.
Just take the Number after the "CE" and Multiple it by the Version Number. If the Result is an Odd Number then add 17 to it and then Divide by 4. This tells you the Ohms that the Clearo is.
If the Number is Even, then take the Square Root of the Number and Round up to the Nearest Prime Number. This tells you the Month the Clearo was produced.

Cleotis Edwards doesn't sound Chinese, he sounds like a moonshiner in Tennessee.
