Yeah, about 15w max VV/VW Mods...

[DeadbeatJeff]

They kinda really don't do the job, do they?

Just coming off my VAMO V5, which is the only one I really have experience with... have tried a Provari but not for any significant amount of time... and having vaped my new Mech for a few days now, I just really can't see myself ever picking the VV/VW up again, not one so underpowered anyway.

The extra power makes a world of difference, and in fact (in my opinion), makes the vape less harsh in the long run. Now I can do lung hits, and I've found to my surprise that my lungs actually feel stronger for it. Even when I was vaping the same homemade NET... started feeling stronger after just a day. Was harsh like woah at first, but got used to it and now is no thing. This is running like 10w through a 1.8Ω single on my VAMO and running 32w through a 0.5Ω double (assuming a 4.0v batter - the average vaping voltage) on a mech.

Has anyone else come to the same conclusion?

Although I'm not exactly sure of the point you're trying to make - why unregulated mechs can be "better" than APVs perhaps? - is what I suspect.

It's basic Ohm's Law math. Because batteries are identified for voltage, capacity in mAh and potential amperage drain - when calculating variables for low resistance/unregulated mod vaping, I don't ever consider the wattage "end value" as relevant to those calculations... only amperage.
If the continuous drain maximum amperage is, with a margin of safety included, sufficient for the target resistance (or visa versa)... then we're good to go. ;-)

The chart is an example of this relevance. Amperage limits being the primary variable.

The point, I think, is that the resistance limits on the VV/VWs limit you

Rt now I'm only running 8amps, same batteries as I was using in my VV/VW, (pani 18650pf)... the VV/VW simply couldn't push that many amps. Even with the voltage all the way to 6, with a 1.2Ω coil (lowest possible), it's only pushing 5amps.. and the VW setting only goes to 15w, which is only 3.5amps.

I suppose the real difference with a VV vs mech is the amperage, and with the VW setting... well, both. the real problem is the resistance limit -- just getting a way cleaner and healthier seeming vape with more power on the mech

But ur rt, it;s really an amp thing. Just sayin, I guess on that note that the VW setting on these mods is even lamer. Referencing the watts and resistance instead of the amps is really a moot difference, no?

I don't really have a point just really diggin the new mech lol

 

[DeadbeatJeff]

I don't really follow your chart though...

...I mean, a sony vtc4 is rated at 30a, and @ 0.2Ω would only be pushing 21amps, and could safely carry a 0.15Ω load @ 28amps...

am I missing something?

The chart is what was available to me as a visual aid to support my comments. Yes, the fellow that constructed the chart has built in some substantial margins of safety.
As it was, I suspect, intended to be a guide for new builders rather than experienced coil winders (who typically do their own calculations rather than rely on charts) - he chose wisely, to error on the side of extreme caution.

Gotcha.

a VERY large margin though... I mean, the chart has the 30amp batteries as unsafe at 14amps, which is sucha large margin as to be sheer nonsense. Was he assuming people were like guestimating their resistances? I suppose maybe it would make sense then. I'm definitely running my 10amp panis @ 8.4amps rt now, as I type, and they aren't even warming up.

But to reiterate, my real point (now that I think about it) is that far from being harsher or more "hard" on my lungs, I find the sub-ohm, high amp hits to be MUCH cleaner than what I was getting at all possible voltages and resistances on my VV. Is this partly due to the extreme oscillation in the duty cycle on the VAMO? maybe, but surely not entirely.

Not a clue on why the chart has such a overly protective margin. It was made by "Steam Turbine" with some information taken from a "Baditude" blog. It might serve to save a n00b from blowing their faces off... but after that, as you've determined, it's overly cautious.
I still use it... when there is a question as to functional variables and their applied value, but not as a resistance to amperage hard reference. Better the individual learns Ohm's Law than to rely on any chart.

The problem with words like "hard", "harsh" and "cleaner" is that they're subjective. My harsh and your harsh, depending on individual experiences, can be at opposite ends of... the harsh spectrum.
It's too bad that we can't find descriptors unbiased by personal experience... the same for one and all - to define certain concepts and perceptions. Even if we attach a numeric scale, say 1-10, without a universal baseline, it's still relative.

As a retired technical instructor, I can deal with hard facts and numbers all day... it's subjectivity that causes my brain to glaze over, like a day old doughnut. ;-)

Well, let's say the higher power is giving me vapor that has had a noticeably more positive effect on my lungs.
