I haven't tried one, but assuming it's default Ni setting is the same as on other Mods (like iStick TC40W, Invader, VTC Mini, Cuboid, etc), which I think is also called "Nickle 200", a temperature setting of 230F or so is on par with what we've seen in those other Mods. However, if (like the iStick TC40W) you cannot turn the power down to about 12 Watts (like on the Mini, Cuboid, and iStick TC100W (which I'm currently enjoying testing.....)) you're hammering it with the full 40 Watts available (as the TC40W does), not at all a good thing to be doing?
Can you also set the power when in TC mode?

So… I'm not a huge poster on here, but felt I needed to interject something. Bc I keep hearing this thing about the iStick 40W TC only does TC at 40W, so it's blasting at 40W the whole time.
This is simply not true IME and there are two ways to prove this to yourself. One is to either look in the mirror while you hit it— so you can watch the real-time W readout in the bottom left of the screen. The second is to hit your CDA at 40W in W mode, attempting to pulse it at about the same pace as you see in TC mode. You will crack the donut before even completing the very first hit.
I and several others who have accidentally left our device in W mode at or near 40W can attest to this. Near 30W, you can pulse a couple times and *not* break the donut if you notice it fast enough. Like "Woah this bad boy is hitting hard right now… What's the deal? Oh crap it's still in W mode." the CDAs can survive a couple pulses at 30W, but at 40W if you hold down for even one complete second, the donut cracks.
For these reasons I reject out of hand any claims that the iStick 40W TC only performs TC at 40W. You can see right on the screen it is not doing 40W the entire time. When I first fire on a cold donut, it might read in the low 30s for a split second but quickly goes down to more reasonable values. Not sure anyone knows exactly what algorithm it does use, but the iStick 40W TC mode is certainly doing something more sophisticated than simply firing at a steady 40W and dropping off when it hits the target resistance.
Furthermore, would like to note that after trying other adjustable-wattage-in-TC mods, I still think the iStick 40W is the best fit for the 2.5 CDA of all the mods I've tried. Mostly bc of the simplicity. I didn't find any benefit of adjusting the W in TC. And here's why…
The only real reason to turn the W down is bc people think it's "hammering" at 40W the whole time. It is certainly not bc they think the donut is getting too hot or heating up too quickly on the iStick 40W. This is why so many new people (who are new to CDAs coming from glass globe or other atomizers) think the CDAs don't hit hard enough. Since it turns out not to be true anyway (in my understanding) that the iStick simply does 40W the whole time, plus some feel it takes too long for the CDAs to get up to temp, it seems to me that this turns out to actually be an argument for turning the wattage *up*. Certainly, turning down to 12W in TC (at least on three different mods I tried this with) did not hit any better than the default TC mode on my iStick 40W.
But turning the wattage up didn't seem to do much except stretch out the resistance of my donuts. Once the cold resistance gets over 1.0, the donuts will not work in TC on most mods and only work in W mode after that. Yes, they started producing vapor faster, but it ruined the donuts.
All the TC adjustments the iStick lacks would only be necessary for me if I intended to also use the mod for devices other than 2.5 CDAs. True, there's only one TC mode (no Ni vs Ti, etc, but… it's the perfect setting for our CDAs). There's no adjustable TCR value (but the built in curve seems perfect for our CDAs). And there's no adjustable W in TC (but again, the built in algorithm seems to be perfect for CDAs).
This is a lot of words that boil down to my belief/experience that:
1. iStick 40W TC does not simply bang at 40W the entire time.
2. Changing the W values in TC mode, for me, did not provide any substantial benefit, certainly none that were proportional to the extra complexity involved (or the risk of ruining donuts).
I'll add that after going through several mods with replaceable 18650s, I'm considering buying a second iStick 40W TC bc the battery life is on-and-on. The last half, certainly last third or quarter of any 18650 battery charge is totally bunk. However, I still get great hits out of my iStick 40W down to the last 5th of the battery charge. Back when it was my daily driver mod, I would vape nic and concentrate all day long on the single charge, only recharging at night when asleep. But now I switch batteries about 3 or 4 times a day— that is just for my Nic rig. The iStick 40W is now dedicated to CDAs, and I never hit the CDAs on any other mod. I carry around both devices, kinda sucks. Been thinking to buy second iStick and just carry it as a backup instead of carry all those loose batteries.
I realize others have had different experiences w iStick vs other adjustable-W-in-TC mods and maybe it's bc I haven't tried it on those exact same mods. I did this on iStick 60W TC (yes, W is adjustable in TC, has Ni and Ti modes), KBOX Mini 60W (same adjustment capabilities) and a friend's mod that I didn't get the brand name on. Head said it was a clone of something but I don't remember of what.
