Pwm is popular now with a subset of vapers who want to control it with a dial. But back in the day it was a big deal to get pwm vapes and considered undesirable. Inconsistent power delivery. Now I see people looking for them. Why would anyone want to go back to inconsistent power delivery?

Don't all regulated mods have PWM? Some just did it better than others, which is pretty much still the case today, unless I'm mistaken. I'm not certain though, so...

That old stuff you're talking about was the original karp out of China, that ran at only 30 hz. I don't think too much is in that range any longer. Even the cheap stuff gives a pretty decent vape.

Little while back I got an SVP 2 on an impulse. I think it was the fault of someone in this thread. Probably JC. It usually is.

Anyway it's a pretty good mod for someone who doesn't use major power. Apart from its enormous length. And the + - buttons are exactly the same distance from the bottom as the fire button on a Provari. So quite often I'm sitting around watching the tele not paying attention, puffing away on it and pressing the + button, until I realise I'm not getting any vapor.

I do wish they provided a tube for 18500. You get a shorty tube for 18350 but I don't have any of them. It wouldn't be a big deal for them to knock out a middle sized tube section.

Aren't there two methods of delivery? Pwm and D.C.-D.C.

I believe the DNA 40+ boards use a dc-dc converter (and the custom DNA 20 in the Innokin SVD), and possibly the Evics and Wismec regulated mods. I expect any device that can't go below 5-7 watts uses PWM to buck power down. I haven't used a Smok product after early bad experience with their PWM as it gave me a burnt taste at lower power levels, and won't get any Smok devices still.

The 800hz ProVari PWM is as smooth as DC IMO, while the rest aren't smooth enough for me.

Calling all experts!

I thought the latter was only for mechs, but again, I'm no expert. DC implies it's running off battery power, but I do data (not mods).

Somebody...(please).

Yes, the SVD2 is a nice, low power mod. Have both the black and the silver/SS, and both of mine came with the short tubes for 18350. And the case. Surprised yours didn't have it.

Find a friendly machinest?

Yah this was what I bought and my experience too. I find it odd that people would deliberately aspire to pwm mods right now in most cases. I agree provape did it right. I can't think of another who did.

In regulated mods now pwm is not that common anymore. Afaik. Too many people don't care for the rattlesnake delivery.

Several ways to convert a DC voltage to a different level. Different chips. PWM, simply put, controls the "on" time of full voltage, so you get an average. E.g. if 4 volts is "on" half the time, you average 2. Mods would also need a circuit to increase the voltage, or they'd not be able to ever provide a higher than current battery voltage. So what you get it rapid pulses of full voltage. If fast enough (Provari) the user doesn't notice.

DC-DC converters use different chips to actually deliver a continuous voltage, as user specified. So on an oscilloscope it would be a straight line at the set voltage, where PWM would not.

Thank you, sir!!!

Corrected, I stand.

I've wondered at times whether the concern about vape temperatures getting high enough to create more of the "nasties" are affected by PWM, as it pulses high power. It seems that a dc-dc converter wouldn't create those momentary heat issues.

That would explain the Billet Box then. Are the other examples, for my brain?

If I am checking out a mod I go to the chart guy. If it fires a flat signal at the minimum I might consider buying it.

Little while back I got an SVP 2 on an impulse. I think it was the fault of someone in this thread. Probably JC. It usually is.

Glad you like it.

Lock the selected Wattage (Hold both the “ + ”and “ - ”
buttons for five seconds)
After setting your wattage you can lock the setting to prevent
accidental changes to your wattage. Press and hold both the
“ + ” and “ - ” buttons for five seconds to lock your settings.
The screen will show “ POWER LOCKED HOLD UP DOWN ”
and current setting parameter of wattage ,Press and hold the
“ + ” and “ - ” button for five seconds a second time to unlock.
Please note that all other functions (such as ohm check and
battery check) are still functional while you have the wattage
settings locked.

Hmmm leave the rest of us inquiring minds hanging.... ;)
:lol: It was my dad and husband #1. It's been years since I've been tattooed.

Well, I think I'm done with my TC tinkering for the time being and esthetics be darned I threw my KF v5 mini on my Jac. It's scepter-like but I'm choosing not to care. It's vaping fantastic.

I did get the 18350 tube section and the case. I was just bemoaning the absence of a 18500 length tube.

I think it would be hard to manufacture a tube because they are tapered.

    Rant
    ----

    Also I'm tired of hearing about pseudo mech mods. Either something is a mech or it's not. If it has electronics it's not a mech mod. If you're going to have electronics for safety protection and battery regulation you may as well buy a proper regulated mod since you're still running the risk if things going bad.

    One mod that comes to Mind that people seem to really like and continue to call it a mech when it isn't is the noisy cricket 2. If you're running through protection you're not getting the benefits of a mech imo. A mech with a kick is passable
    I guess since you can run it without the kick

    /rant

    Finally - why can't we see battery advancements in sizes other than 18650? Why are 18500 batteries still around 1000mah when they should be more like 2000 at this point based on size. And why don't we have proper 1200-1500mah 18350? Instead now we're seeing people move to 20700 and 26650 which offer about the same mah but have a higher amp draw potential. Stupid direct lung is driving the market.

    I think I'm kind of cranky today. It's hot and humid and I can't walk my dog. I've been on Reddit too much too!!
    I know next to nothing about PWM, so I'll leave that part alone, but I can understand the appeal of unregulated devices. You do still get the vape of a mech (ie it is wholly dependent on your build) and some people want that while still having some protection. I don't think it's a bad thing.

    Noisy Cricket 2? Yeah, not a mech and shouldn't be called one, but I think much of the appeal is the fact it can be used as both a parallel and series mod.

    On the battery subject I think most of the innovation and improvement is driven by other industries. The 20700 wasn't developed for vaping, it was developed for the auto industry for example. With that said there are limits to what can be done to improve an 18350 based on size and chemistry. I doubt they could ever reach anything close to 1500mah without a better battery chemistry being developed, though I'm not an expert so I could be wrong.
