Finally found the technical explanation of the differences http://www.e-cigarette-forum.com/forum/blogs/rader2146/3499-what-rms.html

WTH?! I made a post about it being PWM a little while ago. Can't see it now.. Did I not hit submit?!

It's there Dusty... just above my post about the same thing

From what I remember of the chatter, the Isticks are PWM chips. They will run hotter at lower voltages. PWM provides around 25-30% more power than the actual setting.

Precisely. Have I ever said I don't like PWM?

 

[Bronze]

PWM is fine if it is running at super high frequencies like the provari (in fact it is awesome at super high frequencies). At these low frequencies it's crap. Never liked that vape. Even when setting at lower power settings to compensate. I'd get a lot more spitting with cheap PWM like on the VAMO, Lavatubes, and seemingly the istick. Too herky jerky.

But PWM that uses RMS instead the AVG equations... is pretty close ( not the same ) as the output you'd get on a pure DC device...


... the not the same part... it's still going to the highest voltage for those split moments during their pulses which can cause a juice to seem to burn at a lower output setting than the pure DC. This is part of why I've gotten 3 different CDNA/DNA devices in the last few months... I like them all even though a couple of them are a bit heavy and/or big

Retic, just put a .7ohm, .26g, 3/32"id with a split cotton wick on the Rose. Slapped it on the Gus and filled it with Shadow. Wow. Thank you for pushing me towards this. Plenty of juice capacity, great flavor, good vapor. Impressed.

Hey guys, my KFL+ clone arrived today exactly two weeks after I placed the order. I set it up in nano mode and it seems like it's the perfect size for me. I still haven't built my first coil on it, but willl once I watch a few youtube tutorials. I hope it hits as well as the KFM. So far I notice it's basically the same thing but with two screws on the bottom. I'm guessing one is a fill hole and the other airflow control. I'll know once I watch a few videos on it.

Anyway, I've been having some issues with my Eleaf iStick. It seems to run hot when fully charged even at the lowest settings. After an hour or so of vaping it seems to level off, and then it works perfectly. I was planning on buying a couple more of them but will hold off until they come up with a newer version which hopefully will address the issue. It's a bummer because it's perfectly sized. I'll probably get another MVP2 instead now.

Congrats Voltron! You'll find the KFL has a bit more room to work in, but basically it's the same build as the KFMini, which will make it easier actually. You're right though, the larger screw is your fill hole and the smaller one is for air flow control.

I'm loving my ZNA clone. You might want to look into one of those - it has a similar form but I think it's a little bigger than the iStick.

As has been reported in many places... the iStick is using PWM output and it is using vAVG instead of vRMS to calculate what the setting shows you. This is the same issue that was seen years ago when PWM devices were first becoming popular... on the Vamo ( called simply AVG and RMS on these devices ), the issue was resolved with the v2 model which included both the AVG and RMS setting.

In reality... vAVG isn't wrong per se... it just isn't the same amount as what you'd experience with a pure DC output device at the lower settings and the difference is less as you increase the voltage output... they should have used vRMS which similates the value that someone vaping on a pure DC output device like a Provari, DNA ( China DNA ) or similar device.

In most cases... you can simply adjust the output to what feels right to you ( lower voltage )... in reality, you should do that anyway. The only problem is at the lower voltage settings you may not be able to adjust down further in some cases.

Yep. It's all revealed in the numbers. The PWM in this device is around 48Hz, which may be better than the 33Hz used by most of the low cost PWM devices.

PBusardo showed that it is using average in his review. As you said, vAvg isn't wrong, per se, but it has other limitations that prevented me from buying one.

I've linked to where he starts doing the "numbers" in his review here (if the link doesn't jump straight to it, it is 22 minutes in):

If you get a chance , try it with duals or a heavier gauge lower ohm build and see what you think .

Git'r dun Voltron . The KFL + works the same way as the KFM and yup one screw is the AFC and one screw is for filling . Innokin will be coming out with an MVP3 shortly so you may wanna hold off on the MVP for a while , it should be worth the wait .

I'm thinking maybe the Innokin VV3 could do for now, until the MVP3 comes out. It looks small and it may fit my needs. Plus it's priced at around $25.

I'm not real sure if the VV3 has enough oomph to satisfactorily run a KFL + on , at some point you'll want to transition away from the throw away devices just to save money .

I just think the current mods and the big batteries will become obsolete in a while when smaller ones with the same capabilities come out. Just like it happened with cell phones, you know?

Also, I don't think I'll ever build a coil below 1.5ohm, so I'm not sure if I really need that extra oomph. You don't think it could handle that type of build?

It's more or less tied into what the battery can provide consistently , I have some VV ego style batteries laying around and they just can't provide consistent power across the voltage range on them . I don't subohm Kayfuns , they weren't designed with that in mind and they're not good for it . I build Kayfuns in the 1.2 - 1.5 range . Most of the clearomisers meant to run on an Ego style battery use thin high gauge wire 32-34ga and the Ego batts just don't have the oomph to deliver a consistent vape with heavier wire no matter the resistance or power level IMO .

So I guess it's another MVP2 for now. I wish they sold them bare bones without clearos or anything. IMHO, both the iClear16 and 30 suck, so it's basically a waste to include them with every battery.

It's probably your best bet for now , the MVP has great power delivery characteristics across it's range , have you tried shopping around ?

Yes I have. So far the best deals seem to be from 101vape ($40) and 3Avape ($35). After I get one of those I'll wait for the MVP3 or a newer version of the iStick to come out.

 

[Bronze]

I hope they ditch the PWM on that iStick. Can't figure out why they incorporated it in the first place. It had been soundly rejected in the past.

FWI ... Focalecig has a Hana Mod DNA 50w for just under $48 in several colors.
