but who is to say they are not meaning Joules - Per Second ;)
That's exactly what they mean. Thing is, we've already got a word for "joules per second," and that word is called "watts." So calling them "joules," without the "per second" part, isn't just wrong, it's also redundant. They had to misuse a wrong, shortened version of a phrase, just to be "different," when there was already a perfectly good, well-understood, already-short word, already in use, that means the same thing, which they could have used instead.

The joule, is named after James Joule. He worked with Lord Kelvin to develop the absolute scale of temperature the kelvin. Joule also made observations of magnetostriction, and he found the relationship between the current through a resistor and the heat dissipated, which is now called Joule's first law.

So why do TC mods use Joules for power measurement and not Kelvin for temperature measurement?

Yeah... Some Purists consider James Joule to be the Founding Father of e-Cigarettes.

Joule heating - Wikipedia, the free encyclopedia

Electronic cigarettes usually work by Joule heating, vaporizing propylene glycol and vegetable glycerin.

BTW - I'm with you on the Kelvin thing. See Post #34.

I have no doubt that the YiHi board does a good job at whatever it does, but I have yet to hear a sensible explanation of what that has to do with Joules.
OK, here is your sensible explanation. Yihi is trying to sell a mod for $200 that everyone else sells for $50. So their marketing department decides that they need to include a secret sauce. They called that secret sauce a Joule. Which is nothing other than a watt for anyone else.

It's all marketing guys, no need to ponder the secret sauce, there is none. The Emperor has no clothes, despite the crowd fawning over his Joule encrusted garb.

For anyone trying to find some torturous route to the idea that Joules and Watts are somehow interchangeable, I do not live 250mph from New York City. It's 250 miles, and it always will be.

Nor is the speed limit on the local highway 55 miles.

These definitions were worked out centuries ago, and there is nothing Yihi marketing can do to change them. They can, however, spread a form of FUD in order to sell the nonexistent secret sauce by misusing these basic engineering terms. And they have obviously done a brilliant job at that.

1 watt = 1 joule per second.
1 joule = 1 wattsecond

I still have no idea why some mod show joules; if they are using the term correctly then maybe it stops firing after delivering the specified amount of joules; if they use 'joule' when it should be 'watt' then i have to wonder what else they got wrong.

To say it's possible that the mod stops firing after delivering a specified amount of joules is to give credit to the company for having a research and development department who came up with a new idea. It doesn't sound like they are actually advertising a new idea - or the company would be highlighting that advancement in every advertisement as well as plastering it all over their website, not just simply using another word - which is all the company itself seems to be doing with this particular product.

And since it seems to be simply using another word verses saying "Buy this our R&D came up with the most awesome product on the market today" then I would say its just someone decided to sound different than the rest.

Most people would just assume as you did by its usage, that it will stop firing... it might be something you can write to the company about and ask though.

"it's possible that the mod stops firing after delivering a specified amount of joules ..."

That implies the mod controls and limits the length of the hit you can take. No way. Ask anyone that owns a Yihi if their mod goes cold on a long draw. Doesn't happen. And why would that be considered a feature?

What a Yihi does do is behave exactly like every other TC mod, except it displays the word "Joules" instead of "Watts".

It would be considered a safety feature actually. My ego does it to me, but it is set for something like after being on for 10 seconds then it will shut itself off, or some such thing.. (I forget how long, but it is a length of time and it will shut itself off)

Now, I have had the unfortunate experience to be in the middle of a draw and the stupid thing turns off. Leaving you saying.. wth?
lol..

but if it does turn itself off after a certain length of time.. that puts it into the safety feature category, which would be why a company would do it. And they will advertise it, because its supposed to be a plus since there aren't very many people like me who either can do that, or will do that. I would imagine most people who vape with an ego have not had that experience.. while some few like me will have experienced it.

Most regulated mods have a timed safety shutoff. So it doesn't melt down while autofiring in your pocket. Or the firing switch fails closed. But you are arguing that *maybe* Yihi added a user adjustable shutoff value, that is not time dependent but total power dependent. And failed to document that in any way.

This is simple to test... set the device to 10J and see how long it takes to time out. then set it to max J's and see how long it takes to time out. I'll bet the time out is the same.

Simply because the J setting does the same thing every other TC mod does with a W setting. Which has nothing to do with a safety cutoff.
