Hi Nubee,
Good questions one and all - and what I'm about to tell you, probably is going to explain a lot, and help very little...
Okay, first things first:
"Nomenclature Standardizations" - so here's the deal, there is no Nomenclature Standardizations in the e-cigarette world...
Now what this means is simple, but to understand it, let me give you a little example: "DVD-NTSC"
So here's what happens in every other industry - a group of manufactures gets together and makes an agreement called
"A Commitment to Nomenclature Standardization" - it makes life easier for everyone... So, once this happened in the world of home entertainment, Sony, Panasonic, Toshiba, etc, can all use the name "DVD-NTSC" to refer to the same type of disc.
In other worlds, "DVD" isn't anyone's brand name, no one single person or group owns it, instead, it's a shared "Nomenclature" that tons of manufactures can use all referring to the same thing. Meaning, all DVD-NTSC discs work in all the different kinds of DVD-NTSC players...
Simple right? It happens in every major technology industry, it allows all the manufactures to make compatible products, and differentiate
brands, nomenclature, and
models - but it hasn't happened in the E-Cigarette world yet...
It a little confusing, but here's what has happened instead - "Attack of the Clones" . . .
So, 510 is a technical nomenclature for a specific 'external thread pitch' - but that term was borrowed from the hardware industry, where nomenclature is standardized...
Suddenly, companies started to use the 510 thread with different 'gaps' (spacing to the battery contact) so all of sudden, you've got two products labeled '510' that look like they should work together, but then they don't.
Then, Joyetech introduced a Product called the 'EGO' this was just a model that they owned, and it happened to use a 510 thread pitch with their own Joyetech gap.
It got popular, and half a dozen other companies released products that looked identical, but had different internal parts, and they named them 'EGO' as if 'EGO' described a specific style of thread...
Then, all of sudden 'EGO Compatible Accessories' started to appear designed to fit the original Joyetech EGO...
...and the clones needed to make sure their products where compatible, so the phrase 'EGO Compatible' become a nomenclature. But no one ever made a formal agreement, so it is possible, that the words 'EGO Compatible' can appear on a box or description, and in fact, the item is not actually EGO Compatible! Because, 'EGO Compatible' doesn't actually mean anything...
Cool right?
Here's where it gets fun - - -
A few companies saw this confusion and decided to cash in by creating their own models based around the original EGO. Suddenly, VGO, KGO, IGO, GOGO, and ZERRO all appeared, each with a unique fitting at the end, and of course, most of them advertising 'EGO Compatible' even though they don't actually fit EGO devices...
Now, here's where it gets even more fun: Then the manufacturers started to 'Cross Clone' each other, and use each other's names for products...
So one company makes KGO one way, and and other company makes it another way, yet both companies call it KGO, even though it is two different things, and then to make it even more complicated, they both advertise 'EGO Compatible'
(which as I said, technically is a totally meaningless statement)...
So does it all make sense?
You bought a KGO, and it is likely a pretty good unit, and a thread may start where people will start to explain things to you, maybe even other KGO owners, but then all of sudden - things will stop making sense, and you'll follow a recomendation and it still won't fit!
Because another person - even a person who owns a KGO, may have a totally different thing with the same name...
So the trick is going to be:
1. If you can post an image of the actual connector, I can likely help you identify a good compatible vendor.
2. If you can tell me where you bought it, I can likely identify exactly who made it and help you find compatible stuff for it.
Fun stuff right?
I actually have two completely different units both named KGO sitting in front of me right now... Neither of them are EGO compatible, and neither of them are compatible with each other...
It's irritating, but it's also kind of fun in a way to be part of an industry before even the nomenclature has stabilized, it's like being a gold miner looking for that one sweet find...
