Mechanical mod vs VV\VW mod

[6steelstrings]

Why would someone prefer a mech over a VV\VW?. Seems to me being able to vary the voltage and\or wattage would be the better route to go.

Please explain the pros and cons to a noob. Thanks.

You can change the resistance on your atty to get the same effect on a mech. People prefer mechs for many reasons. They're unregulated, so there's no amperage limitations. They're more durable. They're better looking. There's more variety. There's no circuitry. Energy transfer from battery to atty is more efficient, which gives a better hit.

The downside is voltage drop. As the battery's energy dissipates, the quality of the vape does as well. A day in the life of a mech user requires several battery's.

For new vapers I recommend a vv/vw.

For experienced vapers I recommend a flexible mech which can take the common battery sizes with and without kick and fuse.


The mech is important to have as a backup;

One common problem is the 510 threadwell and center pin; standard ego batteries suffer from that problem too, but they may die out otherwise before the problem show up; a mod on the other hand could last indefinitly, and sooner or later the center pin is going to give out; or maybe the 510 threads will strip out as seems to be a common issue on the vamos.

With the mech with a kick and replaceable parts, you have a modular system ;

otoh
the vamo parts are also obtainable- the press fit at the front is a pain though;

Edit. Never mind.

Good answers. But what is a kick?

Good answers. But what is a kick?

kick module goes in the tube with the battery.
gives you vw or vv depending which one you buy:

It's not even my thread, but this post is hugely educational for me. Thank you.

I've had this black hole in my mind regarding mechs. I understood their basic specifications, but not so much the "why's". Now I know far more than I did when I woke up this morning.

You can't do sub ohm on a VV/VW device. You have to have a much for that.

Now that is where I get confused. I assumed that you would need a VV\VW mod for sub ohm coils because you can setup the voltage and wattage to safely match the ohm rating of your coil. Why don't mechs blow up or burst into flames with sub ohm coils?

Other members here can answer that question better than I, but I will share a very valuable tool that veteran ECFers have often recommended, and which should make the mathematics of sub-ohming more clear. I've used it since I started doing VV and different coil resistances, and it'll become even more valuable if I one day venture into mechs and sub-ohming.

I understand the ohms law calc, and that is where the confusion comes in. How can you calculate anything if you don't know what your voltage is at any given moment. With voltage drop, your voltage is variable and dropping as time goes by. I am very confused.

vv/vw mods have built in short circuit protection.
Short it out and it won't fire.

Short out a mech and what happens next is the kind of Battery you have in it.

Barely use mods anymore. Built a Duke clone and nothing compares IMO. No more rotating and constantly charging batteries. Superb vape every time. Lasts for days. I only charge batteries 3 times a week. Since I have mods I may use them more in the future when I get more tanks just to add some variety but that would only be for entertainment. If I wasn't using this device I would probably still be using mods so they are good just more time consuming and not as consistent.

I prefer my VV/VW over a mechanical (never tried a mechanical mod yet, but then again I have no desire to sub ohm!)Call me strange but I will stick with my VV/VW mods over a mechanical any day! It's just a matter of personal preference and that is mine! I don't need to fog myself out of the room with a huge plume of vapor I just want to be able to enjoy my juice and be content doing so which I am with my VV/VW mods.

VV/VW devices have protection circuits that prevent firing coils below a certain resistance or at a current over a certain level (generally 12-20 amps). A mech is really only limited by the battery you are using so you can fire low ohm coils at considerably higher current. In a mech if you exceed what your battery can handle, you are going to have problems.

So what's a duke clone.

google doesnt know.
gossmods doesn't say

Ok, so with the replies I have gotten here and also from reading another similar thread on the fasttech vapers forum mechanical mods, why?: FastTech Forums, I have a better understanding. The way I see it is a mech is either for those who wish to do some experimenting with sub ohm coils, or for those who want a simple, no nonsense device using off the shelf attys. For me, I want to build my own coils, rather than buy them at $3-5 each, but I have no interest in sub ohms or cloud chasing. I want something that I can charge in the car, or off my computer. And I just want to vape without worrying about whether my battery is going to explode. So without knowing that I was making the right choice at the time, my MVP 2 is the best mod for me right now. I may also get an SVD for pocketability. Thanks all for your replies.

You definitely sound like you want to look at these $5 gizmos. No battery.

Vape of usb, on your comp, wallwart, or car.

Now that is cool, but kinda hard to use while walking the dog.

One of the "features" of a mechanical mod is that it can indeed blow up or burst into flames. Fortunately very seldomly if the user does not do anything stupid.

If you go over to the Ohm's law calculator you can see that if you have a .2 ohm coil at 3.7 volts (what you get from a Li battery) you need almost 70 watts or 18.5 amps. most VV/VW mods stop at under 20 wats. They also will not fire a coil under a certain limit, usually around 1 Ohm.

At .2 Ohms you can get a huge cloud of smoke. The charge also only will last a few minutes. A cheap battery can not produce 18 amps and will overheat and possibly explode or burst into flames. You can screw up the coil and build it at .1 Ohms and then even the expensive batteries will fail and possibly hurt you.

A VV/VW mod is great until you want to go outside of it's capabilities. One design criteria is to try and keep you safe, it has a max wats and min ohms and turns off when the battery gets low. But, if you really need the 45 watts nothing beats a mechanical, yet.

Also, since there are no electronics and not much more than a tube with a switch at one end and a connector at the other they are easy to make and some talented metal workers out there do some incredible design work.
