Kayfun LITE - Part 2

[2legsshrt]

To my knowledge (and I could be wrong, but I'm probably not ), there are only two methods of DC voltage regulation used in ecigs: linear and switched.

Linear regulators require an input voltage higher than the output, are pretty inefficient, and are for the most part no longer used. Examples of linear regulated mods are Notcigs' IPro and BuzzPro, and VariCool box mods. They just use a resistance circuit to reduce the voltage and bleed it off as heat.

Switched regulators are used in almost all VV/VW PVs (from the top-end units right down to eGo and little Joye 510 cig-alikes) because of their efficiency. They can be buck-boost (reducing or increasing voltage) or boost-only (no voltage lower than the battery's input). The output from all switched regulators is a pulse train signal (PWM). The pulses can be filtered or of such a high frequency that there is very little noticeable variation of the output voltage during use, but the output is still being generated by switching the current on and off. But, regardless of the smoothness of their output signal, they are still PWM.

I know there is one or more VW mods using an AC output from an inverter instead of a DC regulator, but I don't know anything about it or them.

I wondered about that. I asked PBusardo about the Provari and he said it has the cleanest signal frequency of any Mod around. If you look at it on the oscilloscope it is perfectly straight no small vibrations at all. Thats the one thing I like about his reviews he shows you everything.

Yes, most hardcore NETs will fowl up a coil and require changing within 5 - 10mls of juices vaped. This is where the beauty of rebuildables like the Kayfun come in. It takes me around 5 minutes to open, clean and re-wick a KFL. A very worthwhile trade in my opinion.

What is NET? Been trying to figure it out but normally I can get the abbreviations but this one has me baffled.

Sent with no malice and not a whole lot of forethought from my new Galaxy Tab 4. Thanks Santa!

I'd say the Provari P3 runs like a Rolex. I know the boost feature will increase the vape on a Kayfun. It's amazing on the Silo. The difference in vape quality is like night and day.

I bet we see boost showing up on clone mods soon. I would be amazed if YiHi doesn't pick up on it. With both Provari and Evolv doing it I am sure the cloners have taken notice.

He was mostly comparing set voltage to actual voltage (watts too I believe). And yes, the Provari was dead nuts. Even adjusted for resistance changes as the coil heated up.

I think you're right. In fact, I think boost (or similar) will be a standard feature on most mods within the next year or two.

PBusardo puts em all on the scope and you see hardly a ripple on most of the chipsets. YiHi SX350 looks flat, so do the DNA 30 clones. There may be some PWM in the process but, as long as the final output is DC who cares. The new DNA40 chip has buck and boost and also has DC output.

Thanks, I should of known that.

They can do what they want but no one will clone, but they will never come close to the quality of a Provari.

Will also try! I know that this is a kayfun thread, but is there a big difference between my mod per se mvp 2 vs, provari or dna in the effectiveness of the kayfun?

Welcome MKID!!!!
I can tell you that you've made the right move going to a Kayfun! It's a great device! There are lots of variations on it, but there's only one Kayfun! Well...there are lots of models of Kayfun...hahaha!

As far as your device (mod) goes, there are differences and similarities between all of them...and you'll find people who are "extremists" when it comes to singing the praises of each. So tread carefully! :wink:

I, myself, am a Provari user. The Provari has been proven to be, inarguably, one of the most accurate and precise devices on the market. They are also damn near bullet proof. And they are backed by one of the absolute best customer service experiences in the world.
All that being said, if a Provari isn't right for you, I for one would never think less of you for buying/using another device.
From what I've learned over my 4.5 years of vaping, I can say that Provari and Evolv (makers of the DNA) are the top "dawgs" in the regulated mod world. I know nothing of mechanical mods.

So, take what you will, and run with it!
Again, welcome!
Pro-Tip: Nevermind the occasional arguments you'll find on the ECF. They never lead anywhere. Regardless of who is guilty of taking part in them...myself included.

Oh, I definitely agree, wasn't knocking the Provari at all. Just taking on general.

Thanks to all, part of the way I do things is by doing research first and it seems that those dna chips are evolving daily (no pun intended) that as noob would probably be too much, the provari appears to be a more stable product. The reason I mentioned the dna 40 is that I have been watching videos on the dna 40 ability to protect from burning ejuice into an unhealthy medium. Can one do the same, manually per se on other devices like the provari?

Do no mean to get of topic, just a quick question.

Not really, but you're not a high power vaper so you don't have anything to worry about. The temp protect is ideal for the mega-power vapers.

Also remember that both the DNA 30 and 40 are superb regulated devices even if you don't take advantage of the TP.

Bronze is correct!
You can manually make temperature control with any mod, but that involves a lot of math, and knowing exactly what is in your e-liquid of choice...this would mean not using the e-liquid above a certain voltage/wattage.
But, again, you're not going to go near the neighborhood of needing temp control, so don't even bother worrying about it! And I definitely give you a thumbs up for considering a Provari. As I said before, it's a top notch device.

True indeed. Though just to clarify, the DNA30's, 40's, etc are chipsets only. The devices they are housed in are open to interpretation. There are some better than others (depending on who you ask) and they are at different price points. Just want to add this for MKID.

Well not bad at $116 plus shipping. Really looks nice and fairly easy to use. I like it. I am not into drippers but have been considering one. This looks like a good choice. I wonder how it would work with NI200? the legs would be fairly long plus they would be touching the rim.

This post might clear the doubts:

Managed to put a single coil nickel build on my new Apollo RDA yesterday. This thing is perfect for nickel wire builds. Easy to place the coil, plenty of room between posts for all the extra wraps and the wire screws make a strong connection. Plenty of room for dual coils as well.

Flavor is very good and the juice well hold a lot more than I expected for an RDA of this size. Build quality is also nice.
The top cap will come off without a lot of force, but not loose enough to come off by accident. The air flow is also very easy to adjust and will stay put once you screw down the top cap.

I am going to order the XTR top cap, the stock airflow is a little tight for my taste.

This RDA stays dry on the outside. No juice leaking from the AFC ring off even any juice residue on the air slots. I have added a ton of juice and have not had the first leak or gurgle.

Very pleased

The Pipeline Pro implements heat protection by firing the coil in pulses. Sadly it's unavailable in the US. You might be able to do the same thing manually, but it probably wouldn't be as effective and certainly not as convenient.

Anyone still using Kayfun minis? I have one and just got another. I almost got the new Kayfun 4 but I have to say, minis are really great. Super easy to build on and I made a coil in which I didn't heat and squeeze the coils together like I usually do so there is a very small gap between the coils. I think this is working out for me much better.
