Joyetech Wismec Notch Coil Preview

Meet the Notch Coil

Earlier this week, Wismec senior designer Jay-Bo unveiled the Notch Coil. This innovative product will appear in both Joyetech and Wismec products. At the beginning of March, I got to see the Notch Coil in person; the concept floored me, while its potential was absolutely tantalizing. Here’s a quick look at the Notch Coil by Wimec and Joyetech.

Best of Both Worlds

To fully appreciate this section of the Notch Coil preview, you’ll need to listen to this Van Halen song. Is it playing yet? How about now? Okay, we’re good.

When Jay-Bo showed me the Notch Coil in his office, a lightbulb went off in my head. It was one of those “Holy crap! Why didn’t anyone do this before?!?” moments. It seems like such a simple and obvious idea — combine the surface area of a Clapton coil with the fast ramp-up time of a traditional coil.

As you can tell by the photos, the Notch Coil has abundant surface area — much more than a typical spaced coil, which seems to work best in rebuildable sub-ohm tanks. The main “body” of the coil is stainless steel, which heats up quickly and provides super-clean flavor (and in my opinion, is safer than other vaping wire materials). The leads are non-resistance nickel wire. I was told that the Notch Coil will work well with temperature control mods, for you guys and dolls that like to…err…control temperature.

As for the specs, the Notch Coil has a resistance of 0.23 ohms and an inner diameter of 5.5mm. I’m curious to see how wicking will be, as I mostly use common coil diameters like 2.5 or 3.0mm. I’m guessing that it’ll feel weird at first, but it will be something that will quickly become second nature.

As for how the Notch Coil vapes, I’ll report on that in the near future. On paper, it looks brilliant for flavor. As you know, we don’t vape on paper atΒ Vaping360. We vape on the Internet. Stay tuned for a video interview with Jay-Bo on the Notch Coil and a supremely cool product it will be accompanying.

a friend of mine got one of these, couldnt get a hit off of it without it tasting burnt af. Do not recommend.

I just bought wismec theorem. And notch coil having a hotspot. So, nothing good for me this notch coil


So 0.23 ohms in single coil mode, do I understand it correctly?


You do indeed, Sir.


I would like to see a smaller diameter (3mm) and a resistance of .7 or .8 on these for dual coil use. Not everyone likes a hot vape.


There will be small diameter versions of products like this (keep your eyes on the front page!), but I’m not sure about the lower resistance. Stainless steel has a lower resistance per mm than kanthal, so the resistance will be low, especially as the diameter shrinks. Also, products like this are geared towards temperature control mods.


In regards to TC, what is the TCR? What are the leads made of? How do we dial this in? What to do in eScribe?


Those are all fine questions. Unfortunately, I only have the answer to one. The leads are nickel. As for TCR, I’d wait until the product is final before providing an answer. I am curious as to how mixing metals alters TCR values or even if it does at all.


Thank you for your response. I look forward to the evolution of these coils. I’ll hold off for a bit.


The lower the resistance, the more wattage you need. I prefer higher resistance and lower wattage. I like the idea of tc so as not to burn cotton on long pulls. My wife burned cotton on the billow v2.

She hasn’t since I got her the wismec rouleux rx200 and the billow v3 using the stock coils incl with the rta. It’s only been a couple days so we’ll see. She has to do two pulls just to warm up the coil at 20+ watts. I got her some nichrome coils (.7ohm) coming with as many turns as the stock coils in the billow v3.
Only with tc can I bump the wattage up for her. Not enough for a warm vape. Just enough to get her clouds on the first pull and not hot enough to burn her cotton.


I disagree with your first sentence. There’s no “need” for anything. It’s all personal preference.

What gauge and how many wraps are those nichrome coils you mentioned? That’s quite high for a nichrome coil.


The lower the coil resistance, the higher wattage you need to heat the coil. Resistance to current is what heats the coil.



Your explanation is a bit off. Wattage (power) is the end result. You don’t “need” more wattage, as you put it. As far as how quickly a coil heats up, lower resistance heats up faster. I suggest looking at Steam Engine for a mathematical explanation.

The larger point is that there isn’t a universal wattage that everyone enjoys. As I said, it’s personal preference. I rarely go beyond 80 watts on any coil. I have friends that never vape under 80 watts.


In theory, a low resistance coil will ramp up as fast as a high resistance coil provided that the same voltage passes through.

It takes much more wattage to reach the same voltage on a 0.2 ohm coil vs a 1.2 ohm coil.

All I know about the Notch Coil is what I read online, but since it’s utilizing SS, it’ll probably be best for TC.

But knowing Wismec, it’s only a matter of time before there will be plenty of variations available for the market.

Definitely something new in a stagnating market.


There are already four companies making Notch-like coils.


I rarely go above 20watts. I prefer a cool vape. If a coil doesn’t produce vapor at 20watts, it isnt for me.

The link to instagram says the inner diameter is 4.8 mm. If what I’ve read, so far, the outside diameter is 5 or 5.5 mm. Guess we’ll find out for sure when they finally get here.


On a related note, early this morning I learned about a product similar to the Notch, but available in 3.5mm. πŸ™‚

And where, pray tell, was that?


My preview should post tomorrow morning.


wismec had nothing to do with the design of this coil. joyetech 100% designed it and jay-bo happen to see it when he was there for a business trip.


I never wrote that Jay-Bo designed it. I’m not sure what you’re talking about.


“Wismec senior designer Jay-Bo unveiled the Notch Coil.” This insinuates that he did. If you don’t agree then you’re completely daft.


That doesn’t say anything about him designing it. Senior designer is his job title. Him unveiling the product refers to how he announced it on Instagram, which is linked in the same sentence. I think you need to learn how to read a little bit better before calling others daft.

I’m with ya Ray. Case in point: Burt Reynolds just recently unveiled the new “Bandit” Trans Am. He didn’t design it, he just was there when it was presented to the public. These dudes are duds.


Burt Reynolds isn’t a “famous” Trans Am designer with his name printed on several TA’s “Designed by Burt Reynolds”. I kind of agree with “D.L.” In his assessment. Although, I wouldn’t call anyone “daft” (since I have no idea what that word even means). πŸ˜‰ lol it did “appear” that “Ray” thought Jay Bo designed the coils. Although if he says he didn’t (believe JB designed them). Then I have no reason to believe other otherwise.

I also found it strange that “Ray” would “argue” with the other gentleman’s statement that a lower resistance coil “needs more wattage”. Of course it does. It needs more wattage just to fire the coil. Anyway, it’s not that important I suppose. When it comes right down to it. One can argument that it is hair splitting over semantics. But there’s my $0.02 if anyone cares. πŸ™‚


Major points for the Burt Reynolds reference!


Looks interesting. I’m curious if they’ll eventually just start selling the coil itself for RDAs or RTAs. Possibly with a small inner diameter. In any case very cool.


Selling it by itself — yes. Smaller diameter — I haven’t heard, but would love to see that. πŸ™‚

This could be a very nice innovation indeed. I look forward to the final verdict.
