Question about mech mod power output

Hey guys,

Been vaping and building for years but up to now, have stayed well clear of mech mods, just mainly because I am overcautious and don't trust myself. However I love the Profile RDA and am tempted by the new dual mesh Slatra. When looking into it there is a REALLY nice looking mech mod (the Arcless) that comes in a kit with it and appearance wise, i want it! So considering having a dabble into mechs, if even just to see what the fuss is about. I know the very basics for Ohms law, battery safety etc and being overcautious, I would also double and triple check everything on SteamEngine first anyway.

My question however is more about the power. So the Slatra RDA comes with mesh options of 0.26, 0.22 and 0.13 (SINGLE) so halfing that for dual would be as below and using Molicell's 21700 battery as a guide, this is what Steam Engine works out the rough equivilant wattage:

0.13 - 136w
0.11 - 160w
0.06 - 293w

Obviously wouldnt even consider the last one even though I find it odd they include something thats going to be that low especially since its sold as to be used on a mech, better hope nobody who doesnt know what they are doing puts those coils in by mistake!!! But even the first 2 seem really high to me!? I know using the mech on other RDAs you could just build up the ohms a little and it would be fine but this is how this is being sold... like wtf?? Am I missing something? Especially using mesh, doesnt seem like the Watts are correct, seems way too powerful considering all the reviews say I wouldnt vape the Slatra any higher than about 110w give or take.

Only thing i can think of is I overestimated the voltage, I was being safe on S.E and saying it would be 4.2v which showed as 32.3A whereas if I work it out based on the Amps instead, and use Mooch's rating of 30, it updates to the following:

0.13 - 117w (knocks V to 3.9)
0.11 - 99w (knocks V to 3.3)
0.06 - 54w (knocks V to 1.9)

Feels like Im working something out wrong. I havent actually bought this yet btw, I want to make sure I can understand everything first before i bite the bullet, might well still just say its not for me but its got me curious so i thought I would ask

your target volts is 3.7 - 4.2v is peak-charge, and sags under load anyway..

I find a parallel mech tastes fine around .2-.3Ω - any lower is nutso, change atties/wire/coil.

For a nice series mech like the NCv1, 1.2Ω is rough for the first hour, but then yer good for a full day or so.

Thanks make sense! but thats what I mean, 0.2 even down to 0.12 max... but this RDA is premade mesh strips at the above ohm ratings... my question was specifically about that...

If I build with the Ni80 mesh strips which are 0.22 each so the dual comes out at 0.11... on a fully charged battery thats going to be wayyyy to much power surely? that the bit im struggling to understand with this 'kit'

Not telling you what to do, but I don't think I'd make mesh strips my first foray into building for mechs. That would not be at all representative of how mechs perform.

You do not have to do anything. You could easily use that RDA you discuss on a regulated mod. In fact, given you are considering using mesh that you feel is either too high or too low, that would be my advice.

This is based upon a tried and true axiom. If you have doubt, rule it out. The idea of the mesh being to one extreme, or the other using a mech causes you doubt. Rule out a mech, or rule out the mesh.

Again, you do not have to do anything. I suggest though you give due consideration to some advice. You are asking for advise, ergo people are giving it. Maybe though, you are the kind that asks for advise to create drama, or effect and you don't consider it. I do not have to do anything either. Still take my time and offer advice if asked.

Cheers gsmit / Mist, thats my thinking as well. i was going to get this RDA anyway to use one my Topsides. As I said in the OP, until now Ive never really had an interest in Mechs, it was just that Arcless is gorgeous so I had a little play with SteamEngine to see, hypothetically, what I would do if I did own it and I just couldnt make sense of the results...

I would be totally fine building regular coils wrapping from scratch on a Mech if I really wanted to because I could fine tune exactly what I want the ohms to be and adjust.

It was just purely that this Slatra dual mesh RDA with premade mesh strips is being sold as a 'kit' with the Arcless mech... and Im curiious if I actually worked out SteamEngine correctly and that it would actually be putting out the equilivant of 160w on the dual Ni80 strips?! Cause if I DID work that out right then its definitely not for me but I also had concern over how these 'premade' things can be sold as a kit when it will be that powerful? If that makes sense?

Not sure what you mean, I havent dismissed any advice so far, I take evertything on board. I know what Im doing in terms of building normal coils, mesh etc on regulated mods, just not mechs. I had tried to work out stuff for myself, felt I must be wrong about my working because the outcome was way off my expectations so was asking people to verify... My only reply so far has been "Thanks make sense!" then going on to ask a followup/more specific question...?

Im a very anti-drama guy! But I do waffle a bit so my actual question usually gets lost in translation so I tend to need to re-specify after no offence or dismissive attitude meant to anyone if that how it came off! Gsmit can back me up for my input in the Profile RDA thread

I have to agree with @gsmit1, learning to build on a mech with wire would be much more beneficial for you.

I've seen mesh strips at 100+ watts on a regulated dry out so fast that it ignites the cotton.

I completely agree and thats the point Im trying to figure out. These are being sold premade for this RDA which is sold with this mod... but surely thats way off?
Are my workings in the OP correct... or have I worked it out wrong? Thats all Im trying to determine here

At 25.40 of this video he shows how you can put regular builds in the rda and aren't limited to using mesh strips.

Your math looks right to me, if mesh is rated at a certain resistance for a single piece and you use 2 you divide by 2 like any other build.

Yeah I've watched that vid, thats what got me tempted by it haha! I would be wanting it for the dual mesh as I fell in love with the Profile so wanted to give dual a go.

But if my maths IS right... then 120-160w worth of power on mesh is ridiculous to me so maybe not for me then! Unless I buy the 'kit' and just use the Slatra on regulated and have a dabble with the mech with a different RDA with regular coils.

Thats all I was looking for, I just dont get how that can work together... all the other review vids saying, 'dont go higher than about 110w on the dual mesh' when the mods its sold WITH will run it at like 160w???

Just confused me and doesnt make sense... but maybe thats a good thing. Last thing you want to be with mechs is cocky and under cautious...

Thanks

You sometimes need to overlook me too. I often look at things six different ways, get myself confused. *chuckles*

Nah, you are good. It was me getting foggy headed. Sorry for that.
