After using modern VW mods, are you happy with the limitations of a Mech mod ?

[Bad Ninja]

Not missing anything that is a question if you notice the funny little character at the end..... "?"

Temp Control itself IS a limitation.
Thats how it works.
SS, Nickle and Ti change resistance due to temperature (much more so than Kanthal) and the mod uses a pre set program to determine this. Then it limits power accordingly.

No question that on regulated mods that use a low-frequency PWM output, it is noticeable, and in fact, disagreeable. However, most modern regulated mods don't work that way; their output is close enough to true DC that this simply isn't a factor. And the a mech mod definitely doesn't produce a sine wave.

Its extremely noticeable.
Its the main reason I enjoy mechs.
Its a different vape.

Being dependent on battery charge level would also be a be a limitation as it will only perform at the desired voltage for a certain range. I would consider that a limitation.

Every mod is limited by battery charge unless its solar powered.
Lol.

 

[SteveS45]

Agree but when the perform is dependent on state of charge and no circuitry I would think the regulated would have better or more constant performance. Not a Mech user so forgive the ignorance if you will.

It's like smoking.
As you get closer to the filter, the experience changes.
Mechs for the win.

 

[Ben85]

I don't think mechs have limitations, just differences. But every mod out there has differences.

Personally, I prefer the differences that a mech mod offers.

One heck of an analogy!

Yeah I just prefer the mech, something about the crackling fresh batteries and to knowing when it's getting time to think about changing them out too. No fiddling with settings and battery gauges, it's a more pure experience in my mind that politely asks you to pay attention to the performance and experience of the vape as the batteries give you all they can in the most efficient way. It makes coil building an art as you try to find the sweet spot, makes tweaking it with different builds satisfying, a small feeling of accomplishment when you get it right, rather than simply pushing buttons.

 

[t8kiteasy]

I love using mech's myself as I build quite low (.1-.2),granted you can run that low on regulated mods too but there is just something about a mech that makes the vape satisfying.

I do use regulated mods too but certain times in the day I prefer mech over regulated.

 

[Bonskibon]

I did a build the other day and was curious how it would work on one of my mechs. It's a different experience, not the same as I get on my regulated devices, but it was good enough. I don't use them much, but having a couple around makes me feel a bit better should things really go south with the FDA.

I find regulated devices mediocre at best and feel that they are for beginners and lazy vapers.

I love the ramp up time, simplicity, reliability and power of a mech. Sure many would disagree but each to his own.

Other than setting up or taking a pull now again with my wife's device, I hadn't used a regulated device in over two years. And she's been an exclusive mech user for almost a year. Six weeks ago I started using a well-built series PWM box. Just a tad more circuitry than a mosfet switch unregulated box. No screen, just up/down digital POT buttons and a fire button. The output sags with the battery; so, the occational tap keeps things pretty level.

I can notice a slight difference with modulated power (it's between 400hz and 500hz). So far it's not bothersome, just different.

I'm looking forward to using a 20700 single cell tube when they become available. I'm interested in how the roll off curve will feel compared to a high drain 18650.

A mech definitely allows you to get to know a battery, in a weird intimate way. Also, learning to build properly for a mech is an excellent exercise for anyone interested in the hobby aspect of rebuilding. It can teach how to better balance a build, things that would take much longer to learn if the user can compensate by adjusting the power.

Yep, my thoughts exactly and they provide a smoother Vape that regulated Mod's cannot achieve. There is a difference between manipulated power vs pure DC.

I prefer the vape of a mech - others have described why quite well already!

But back to the OP - it's not really LIKE what your post implies...

See, the batteries tend to kick down quite quickly from 4.2 to 4 or 3.9.
Then they run for a long while slowly dropping from about 3.9 to 3.7.
Of COURSE how long depends on your setup - but for me, that's like ALL DAY - (certainly if I'm switching between a couple).

So for a few minutes, you get "a little extra kick" - "oooh! Fresh Battery!".
Then it settles down and runs all day.
Then it vapes a bit weak, and you pop in a new battery.
(VERY rare to get down past 3.6)

I am not here to run-down mech mods by any means. In fact, I just ordered a small 17mm wide Mini Nemesis mech mod and a 17mm wide Yiloong Mini Fogger RTA to set on top of it. This little setup will be used when I go out of the house for just a short period of time and don't want to bring a larger 22mm box mod and atty with me ... Something thin and light that can be just put in a front shirt pocket.

Anyway, I have a question ...

Let me start out by saying that I am a mouth to lung 'tootle-puffer'. I am currently using an eVic VTwo Mini VW box mod and a Kayfun Lite-Plus V2 RTA. I have found that my sweet spot is using a 1.3 ohm single Kanthal coil and feeding it 11.5 watts.

It's obvious that the only time I will be able to achieve the 11.5 watts when using a mech mod and a 1.3 ohm coil is when the battery is at 3.85 volts. But how about when the battery is fully charged to about 4.0 volts, or needing a charge at about 3.4 volts?


10 wraps of Kanthal 27 gauge wire on a 5/64" (2.0mm) rod = 1.3 ohms

Volts: . . . . . . . . .4.0
Watts: . . . . . . . .12.3
Amps: . . . . . . . . 3.1
Heat Flux: . .. .. . 119 mW / mm²


Volts: . . . . . . . . .3.4
Watts: . . . . . . . . 8.9
Amps: . . . . . . . . 2.6
Heat Flux: . . . . . .86 mW / mm²
___________________________________________

As you can see, the 1.3 ohm coil will get 12.3 watts when the battery is charged to 4.0 volts, but only 8.9 watts when the battery get down to 3.4 volts.

This causes the coil's heat flux to go from a nice 119 mW / mm2 down to a cold vape of only 86 mW / mm2. Sure, I can change my coil ohms higher or lower, but there will still be a very wide variation in coil heat and vape quality going from 4.0 volts down to 3.4 volts.

And here is my question to you folks .... I guess you folks find this variation acceptable since you use mech mods, but has it become at all, bothersome to you?

I guess we get spoiled with VW mods that has the ability to keep everything constant.

Thanks,
Ron

I use both, but I love the feel of a mech tube, it's just way more satisfying in the hand. Not all builds or attys do well on my tubes, so sometimes only a regulated mod will satisfy me. That is mostly with higher ohm builds, close to an ohm...with those kind of builds, I prefer a regulated, but with builds closer to .1 ohms, can't beat a nice mech.

 

[Flt Simulation]

Thank's everyone for all your input .... Well, my little 17mm wide Mini Nemesis mech mod is supposed to be here today.

The 17mm YiLoong Mini Fogger hasn't arrived from China yet, so I will see how it vapes with a Kayfun Lite-Plus V2 that I already have.

The Kayfun has a single Kanthal 1.28 ohm coil in it now, so at 3.7 volts, it should run at about 10.7 watts of power (which is just about perfect for a 'tootle puffer' like myself).

The 14650 Efest battery for this little mech mod is only rated at 5.0 amps continuous, but at the power I will be using, it's only a 2.9 amp load ... so at least it won't be dangerous.

Ron,

As a consummate tinkerer and a finicky vaper, I LOVE mechs. I always had one but recently began using mechs a lot more and pretty much only use one reg device, when I am driving. I love building and using different RDA's. I keep a stash of batteries on me and a CM K bag with a few mods in my backpack, but that's because I can never make up my mind which mech I want to use. Yes, they can be expensive. No, they are not for everyone. That being said, most mech users I have met are into mechs for the fine tuning aspect of the whole mech experience.

You are much more detail orientated than I, but I get your point.

Personally, I like both. I switch around between my big collection of 18650 tube mechs as well as my 200-220w dual battery regulated and my Provaris.

The mech vape is cleaner and more constant/consistent IME. As with many others, the new battery vape has a bit of a punch, then it levels out and once the battery hits around 3.7v, i notice the drop off and change batteries.

I enjoy tinkering with mechs and RTAs, but slapping a 10 coil prebuilt into a 6ml tank and vaping it at 130w can fun and easy as well.

 

[Lessifer]

The main reason for me using a mech still exists, namely the fact that there's no board to die rendering the mod useless.

Other than that, if you're running your batteries down to 3.4 that would be why you have such a noticeable difference in your vape performance. I would most users change their batteries out at 3.6 at the lowest. I've noticed you prefer the small batteries. An 18650 provides me over a day's worth of great vaping, running around 1 ohm.

 

[Flt Simulation]

Lessifer ... If I used a mech mod as my daily vape gear, yes, then it would be a mech mod with an 18650 battery.

However, I ordered the little Mini Nemesis mech mod just because it is small (17mm diameter) and light weight, for use when I go to the store or on a short trip somewhere ... fits nicely in my shirt front pocket. And being a small mech, it takes the skinny 14650 battery (only 950 mAh)

Anyway, this little Mini Nemesis showed up in the mail box yesterday ... Here it is with a 17mm wide Yiloong "Mini Fogger" RTA on top .... Really nice vape from this little setup!
