Why wattage AND TC? Ok, let me explain. I'm a tweak. I tried my friend's iStick 40 TC, and hate it. Feedback control systems are much more complicated than meets the eye. The iStick's is crude. Yes, it slams the pedal to the metal and overshoots, i.e. overheats. @Hyphy is right. Then I didn't...

Wecome aboard. On non TC units its hard to control the heat on Nickel and Titanium 0.1-0.3 ohm typical resistances, you'll probably burn the wire, the wick, the house ;-) Best to do that on a TC device. A good starting point with Titanium is to use the steam engine calculator with your exact...

The question about whether TC is necessary is a bit like someone asking if a thermostat is necessary in your house. Of course you can manage without one. Just adjust your heater and AC manually as needed, open the windows now and then ;-)

My green KangXin 50W mini VF arrived while I was out of town. The green is dark and elegant, quite a change from typical Chinese colors. This one shipped from England. The previous one from Holland. Rather strange. I never thought I'd say this but the flashlight function is brilliant. While...

On the majority of TC devices with a Nickel curve I see that the Ti offset is 90 degrees. In other words you set the target temp to 360 F to get 450 F on the titanium wire. It's accurate enough. For people who are satisfied with routine use of a VV/VW device, ok. For anything where there's...

I had put this link up weeks ago. I don't think this is convincing, either. The fact that a metal can form toxic salts or that nano particles can seriously irritate the lungs doesn't in the least settle the case, unless it's actually happening under vaping conditions. The people who have the...

I just got 2, count'em TWO!, rolls of Titanium wire 0.4mm i.e. ~ 26 AWG. Cleaning with ISO works well. The most interesting thing was that I get none of the Nickel chest tightness with either Titanium wire. It feels very open, maybe better than Kanthal. I'm done with Nickel wire, I think. Ti...

FWIW, I'm pretty sure by now that the $65 Heatvape Invader Mini 50W and the $40 Kangxin Mini VF 50W use the very same chip/firmware.

The KX50D board used in the KangXin mini VaporFlask uses Watts as a power setting and Degrees F for a temperature limit. I have no idea how the IPV4S' Joules apply, seeing as one Joule is a Watt during one second. But wow, what a black beauty! Each chipset is going to have its peculiarities...

I may as well start by mentioning the TC mod I'm having great results with on everything. You can set temp and watts independently, i.e. it doesn't max out the watts in TC mode, so you can set power low enough that a TC coil never fully reaches temp, or slowly gets there, or high enough that it...

@Haywood i hate coming across like a fanbuoy but when you try a mod with independent temp and wattage setpoint you'll agree it's another "game changer". From setting watts low enough so temp is never reached, to high enough to reach temp like a crash test dumny, and all the interesting in...

@Fredster951 The W9 offerings seem like some of the more successful balancing acts, and a TC mod actually might work with a Titanium Hercules cart, but why would I want a $80 Hercules cart now, or non-TC battery bases? what I want is a way to effortlessly keep the temp of ANY DIY coil right on...

I just wasted a couple of hours watching Busardo Archie-Bunker'ing on and on over irrelevant traces of mod voltages, how he feels the pulses, and how he shelves any device that behaves unexpectedly, even once. OK, Phil, I get it. You're in over your head. Only a few months ago you were...

Yo, @Haywood good to see you, welcome baaaack! I do appreciate Busardo's detail. I guess the DNA 200 is everybody's dream board, but meanwhile as I have been looking at the mini VF's regulation on the scope and, especially for $40, I think it's well done. Also very solid, no rattling etc...

With lower wattage we get to temp more gently. Here's my one hitter quitter short cotton wick trick. Dry-firing (with no burning of course), then with a couple drops of liquid, same setting. After the first second or so, while temp is reaching target, the wattage drops, reading as low as 0.8...

I'm no TC veteran, but I'm seeing reports from DNA40 users and I'd say if you can get something like the KangXin Mini VF, it seems better than the DNA40 family. The DNA40 apparently gives temp warnings, treats reaching temp as a limit/malfunction instead of just regulating, and people find it...

If your Alpha Centauri coil is Kanthal then the mod will normally operate in WC mode. I don't know about "whichever TC device", but my Mini VF recognizes Kanthal even if it's sub-ohm and turns off the TC, showing the target Wattage and the Voltage. If the coil is Ni (or possibly Ti too...

I'm curious why DNA200? The wattage or some other spec? 200 watts?? I can't imagine. I just tried to pulse my 1 ohm kanthal coil for a teeny fraction of a sec in WC mode at 50 watts and got a taste of waste, gas from the dragon's ass. That coil would have to be sitting at the bottom of a pool...

It sort of does. But there are enough differences that it can't be the same board. No idea which is better, all the little box mods now will have TC & WC. The Micro USB charging connector is accessed from the botton because it's wave-soldered to the board. They are all very fragile. If Origin...

Nickel is soft. It can be "tempered" to make it easier to work with in making coils. We're used to dry burning Kanthal, that's different, since it can glow within the range of voltages we normally apply, or on a mech-mod, though when immersed in liquid it's kept cool. The Nickel, Titanium and...
