There's a difference between different pwm's too. My evic and zmax both pulse, but the output is different. You don't know it's there with the evic, you certainly do with the zmax.
APVs: is there really any difference?

Well said Kiwivap....Im a collector myself...like them all for different reasons. Just ordered another one yesterday that makes 6 of them...oh well dang...I have to be addicted to something it seems. At least Im not smoking cigs.
I don't really think the people who say there is no difference have any science to back them up. I think WE have science to back us up. I don't see how it would be possible for a 6+ volt spike at the coil to NOT effect the vape.
I've noticed the problem gets worse with using dual 18350s as well. I was vaping at 10 watts in single 18650 mode, switched over to dual 18350s and the vapor got much hotter and harsh compared to the single 18650. Vapor production did NOT increase either, the vapor was just hot and harsh. I like hot vapor, but not sucking on a furnace tube hot.
The chip is also less accurate in one mode, no idea which one. With a single battery all my Boges ohm out at 2.1. With dual batteries, they ohm out at 2.3
I'm not sure if this is a limitation of the actual technology itself, or just a badly designed board. Going from an input voltage of 4.2-3.2, all the way to 8.4-whatever dual batts cut off at (never got down that far) is a pretty big variance in input voltage. What I mean to say is, if Provari made a device that can take dual batteries, would they be able to make it ohm out the exact same in both battery configurations? Or is it just a general limit in current tech? No idea.
I'd imagine since the chip was reading ohms at 2.3 instead of 2.1 that it would increase the voltage to account for the change. Same wattage setting, different battery config, different calculated voltage output. That shouldn't happen at all. It should read the same ohms regardless of battery config, and adjust wattage accordingly.
Don't get me wrong, I love my cheap VW devices (prefer the Vamo to the Zmax by a wide margin though) but they have their limitations, and I'm not going to gloss over those limitations just because I like the devices. I'm not ashamed to point out issues with stuff I own or like, it seems like once some people buy a device, they refuse to ever say anything bad about it. That doesn't do anyone any good!
I really am happy that so many people in this thread CAN notice the difference. Question: Where was my backup in the thread I created on the subject?
Hi Chuck,
I tried a few little experiments after reading your post. I have never used stacked 18350s before with the Vamo, but did try out a few things using one 18650, and two 18350s today.
First I set the watts low at 5 watts with a 2.5 ohm vivi nova.
With one 18650 this was ok. When I stacked two 18350s the first hit was hard, strong and a burnt taste. I have read that some-one experienced this before but I've never had it happen with an 18650 - so was surprised. After the first hit with stacked batteries it normalised. It did seem to be hitting a little harder - but below you'll see that with this particular vivi nova it was also reading the ohms as 2.7 in the two battery configuration.
On the second vivi nova the Vamo read the ohms correctly in both modes - 2.9 ohms.
I set the Vamo to 5 watts and tried with the two battery configurations again. No harsh first hit this time with the two 18350s. It did feel stronger in terms of the vapor production, but not burnt or anything. Tried with an 18650 - still good but slightly weaker than the two 18350s. I tried some different voltages as well and they were comparable in both configurations. It did seem slightly stronger with the two 18350s but there were no major differences that I could detect.
My conclusion - I don't usually stack batteries on my APVs anyway - there were some slight differences between the battery configurations, and there was definitely one harsh hit on the very first hit with one of the vivi novas and two 18350s.
I measured and compared the ohms on two vivi novas. These were the results:
Vivi nova no. 1
Multimeter - 2.9 ohms
Vamo 18650 - 2.9 ohms
Vamo 2x 18350 - 2.9 ohms
Vivi Nova 2
Mulitmeter - 2.5 ohms
Vamo 18650 - 2.5 ohms
Vamo 2x 18350 - 2.7 ohms
So a difference of 0.2 ohms with 2x 18350s on one of the vivi novas.
In your post on the other thread you mentioned that you got burnt hits with clearos and hypothesised that this was due to the 33.33hz on these devices. I think one reason some people advised you may have been in AVG mode is that we have often seen owners of new Vamos saying they hit too hard and then they have discovered they need to set it to RMS, and come back much happier. I think another reason people didn't agree with you is because it isn't their experience. Up until today when I stacked the 18350s I haven't had burnt hits like you described, and I've used vivi novas a lot. I mean everyday. I had one bad hit with the stacked 18350s - the first hit with one the vivi novas - and then it normalised. This was straight after I put the 18350s into the Vamo, and changed from 18650 mode. It's been suggested elsewhere on the forums that this changeover to 18350 straight after an 18650 can result in a first hard hit if you don't pulse the Vamo fire button once to allow it to re-read the voltage.
I wouldn't say my simple tests today are comprehensive or completely conclusive. I used the same Vamo each time. I own two so I could test out both side by side at some point and see if the results are the same.
At this point my experience with the Vamo and Zmax doesn't mirror what you described on the other thread. On this thread I think you mentioned a subtle difference between mods - it may be there, and I have seen some others say they notice it. But I'm not noticing the burnt taste while vaping that you've hypothesised comes from 6 volt surges.
If I get time I'll do something wider with both Vamos and a Zmax - all in RMS. For now that's where I'm up to with it.

You know... I'm guilty as charged...
But I can tell you right now about a dozen people right off the top of my head that spend WAY too much time evaluating these silly devices and trying to obtain scientific measurements to get a more thorough understanding of the methods behind our madness...
When the truth is... How many folks out there really give a damn?
LoL...
Ever think we're just spinning our wheels here, and we should just sit back and enjoy a good vape?

I agree, Ive always hated numbers, they make me physically ill, ( bad memories of dad drilling me and being threatened with a spanking per wrong answer) so I just go with my "taste buds" and that "ahhh" feeling that I get when I use a good device and atomizer. For me its always taste first, vapour production second.
Well I'm not one Of them. I usually let others do it. This is the first time I've bothered noting down those sort of comparisons etc. But Chuck has posted a few times about this so I wanted to check it and see if my results matched. And I found interesting as something different to do for a change. I don't see why video reviewers should have all the fun.
I don't know. You've posted your observations before, so I don't see the issue here.
No, I think it was interesting to do, and since Chuck posted some of his observations, I tested them out for myself. I don't think its a huge issue, but since we both own and enjoy using Vamos I was interested to check it out and let him know what I found. Sheesh - it was just a few accuracy checks and some vaping comparisons.

This place exists for the purpose of evaluating these devices - compare away!
The more I've read this thread the more I realize I didn't really have that much constructive to say in my previous post here. So, to simply stick with the question posed by the OP, then the answer imo is: Yes. There can be.

Like I said, guilty as charged
I over analyze almost everything I do... But at the end of the day, I like everything I have... It is all satisfying!
From my cheapie eGo passthroughs and stardusts, my Vamo, Lavatube, and of course I love my ProVari... I really love them all!
I get lost in the compare and contrast threads trying to explain the subtle differences I have noticed, but I don't think it really matters if the user enjoys it...
That's all I'm saying really... Not necesarilly pointing fingers, just making an observation... If you enjoy it, who cares what me or anyone else thinks?
Vape strong and vape long brothers and sisters! Vape whatever you've got! If you love it, preach it to your smoking friends!
And if you want my opinion on the difference between a ProVari and a Vamo, I'll share it
Just expect a long speech with a bunch of technical mumbo jumbo that doesn't mean anything...
I don't care what people think of my choices really. As I said, I found it interesting to do. Seeing if an ohms read is accurate and comparing battery configurations is hardly over-analyzing. It was a response to some-one who owns the same APV and likes it. All of a sudden you seem to have an issue with some comparisons of the same APV. If some-one doesn't like a few numbers or something they can skip on by. I think I've pretty much said variety is the spice of vaping in my previous posts. My choices of pvs are informed by comparisons and looking at different features and performances. Methinks you doth protest a little too much.

I thought your post was constructive. There are different things people are looking at here - from form factor to the vape.

I'm trying to be the shepherd... LoL!
In everything I do I've always tried to be less argumentative and more objective... Seems I've strayed off that path a bit here lately... I've noticed, and apparently you have too
I'll get back to my old ways... I was just overjoyed with my new toy and wanted to share that experience... But all too often it comes accross wrong.
I vape at around 8 - 9 watts and my resistance of my RBAs is around 1.7 - 1.9Ω. I have eVics and a Provari and there seems to be no difference in terms of function that affects the quality of my vapes. Either device performs well. However if I were to vape above 11 watts and needed the resistance to go down to 1Ω, then the Provari would be the guy to have comparing these 2 VV devices.

Dam - I haven't strayed off any path. Look sorry, but Chuck posted some observations about the Vamo. I decided to see if mine was as he found his. So I checked some things out and posted. I'm glad you like your new toy. I'm waiting for something in the mail myself. All I'd ask is that you'd step back and allow people to compare notes on the same PV. Since Chuck and I both use it, and both like using it, there shouldn't be a problem here.

I think you misunderstood... What I was saying is I have strayed from MY path of being objective and not so critical
That wasn't meant to be a jab at you! When I said "apparently you have too" what I meant was I think you have noticed I have been a bit critical lately.I also use a Vamo, and did the exact same thing when I read the post
Popped in stacked 18350's and observed the same thing you did!
I think you misunderstood... What I was saying is I have strayed from MY path of being objective and not so critical
Oh, sorry. And no, I hadn't thought that of you. You seem a pretty happy guy to me. I guess that's why I missed what you meant there. My apologies for misunderstanding.

Interesting. I don't use stacked batts usually. Maybe its the foray into RBAs that has got me interested in checking stuff out more. The amount of ohms checking I've done with the AGA-T+... lol.
And now for something completely different..... batteries are there a real difference between Efest IMRs and AW IMR in how they perform the same PV? I usually use AWs but it seems like almost all the AW 18500 IMR batteries are sold out. I bought some Efest instead. Any differences in longevity or how they power up?
I can say I haven't noticed any difference much at all between my AW 2000 mAh IMR 18650's and my Efest 2000 mAh IMR 18650's. I have 2 of each in a rotation, and they both work equally well and give me equivalent vape times. The Efest were a little cheaper, so I'll probably keep getting those going into the future.
I've heard rumors of some Efest batteries being not as good as others... That they are rebranded, and whatever cell Efest slaps a sticker on is what you're getting. I haven't found this to be the case... I have 6 of them in total, 2 each 18650, 18490, and 18350, and they have all performed great.

Being a pretty stereotypical math-phobic English major, I don't really understand why it should be, but an atty that leaves me totally unimpressed on my Vamo comes to life on my bottom-feeding Reo VVG. I don't usually chime in on these threads because I hate to come off as a some sort of product-pumping fangirl, especially for an expensive mod, but I'm thinking about frustrated vapers, already here because they're ready to get the upgrade with the gulp-hard price tag.
I have a great aunt who'd smoked for a billion years, walked around perpetually in the midst of hacking up a lung; and I'd bankrupted myself buying mods and heating-elements, trying to win her over. Flat rejections, all around. It wasn't until she got her hands on my (brand new, long-awaited) Reo that anything fell into place for her; and, although to a less dramatic extent, it was the game-changer for me (once I'd saved up for the replacement).
All that, I guess, just to chime in with another "yes," even though it didn't make much sense to me that the APV would make a substantial difference in my vaping experience, it has. I hadn't taken the time to understand why that might be, nor do I plan to, to be quite honest. I've gotten pretty comfortable in said stereotype, and just might start turning my attentions to writing odes on NET nectars
, or something.
Oh, plus I apologize for the lousy thoughts I'd had about those of you who I'd been pretty convinced were simply justifying status symbols,
on me for those.
