    Good day, I have a very weird, maybe even stupid question about a mech.

    Does a mech really hit "harder" than a regulated mod? I have seen a few people say it does, but I am wondering why this is.

    In regulated mods, the chip can effectively pull more power from a battery, right? so in essence a regulated should/could provide more power? no?

    also, if a regulated is put into bypass mode, again, should it effectively not run exactly the same as a mech?

    So the only thing i can think of, is that, because a regulated runs through a chip, a mech gives immediate power, where a regulated takes that split second or two.

    your statement is true, you can get a regulated to hit hard for sure because you can adjust it to

    but on a mech when you get things just right (mechanically) and the vape is awesome, you tend to say "damn ! this thing hits hard"

    The hard hitting mech is all about the conductivity from battery to atomizer. The less the internal resistance of the mod and connections the better the power delivery and the phrase "hard hitting".
    For example, most mods have a small internal resistance i.e. the voltage at the battery may read 4.2V but at the atty it could read 4.15V etc. due to internal losses in the contacts and material used for the contacts.

    A regulated can hit just as hard but you have more internal losses which can arise from wiring, and no chip is 100% efficient. In essence, you will most likely get the same experience with a regulated but your battery life will be less than if it were a pure mech.

    For example the Evolve DNA 250 has a rated efficiency of 97% and the DNA 250C has a rated efficiency of 98%.

    In bypass mode, your mod will be 4.2V * 0.98 (assuming DNA 250C) = 4.116V at the atty.
    A mech with say silver contacts that's been maintained regularly with no carbon buildup or dirt would feel more powerful than bypass mode.

    I don't want to go into too much detail here but a mech with a higher internal resistance does usually feel "flat" or "cooler" at a voltage of say 3.8 after some use etc.

    Well said Christos, that about covers it.

    My 2c would be that since mechs are used predominantly with RDA's and squonks you tend to build for that hard hit. In a tank my common build is 0.4 but my Arctic Dolphin Crea paired with the Recurve dual gets 2 x 0.4 coils giving me 0.2. @ 4.2 V this is around 88 W when I hit the fire button. I never have a regulated or tank at that W

    @
    This was more than perfect, i feel like Neo in that matrix scene after they uploaded his training

    "I know kung-fu"

    because that was informative as hell, and "I now know mechs"

    Thank you

    I would rather say "I know a little more about mechs".
    When you have had a battery vent, you will then be cautious!

    Oh! This actually something I also wanted to ask, I am looking at a mech. (the VV requiem) hence the questions. I have already read up on all the safety stuff etc.

    Two things I can't really find info on.

    1. Can you use a mech as adv device? Aka chain vape it the whole day? (this might be a very noob question)

    2. When it comes to battery drain, I understand that you will feel when the batteries get drained. But, is it dangerous to keep vaping then? I, with my regulated mods. Look at the screen and see. Oops. Need a fresh set of bat's, but then tend to vape it some more until the mod basically says "nope". In a mech. Will this put to much strain on the bat's?

    What I do with my mech squonkers is to vape it until I feel the battery go off. Then pop it in the charger real quick to check the remaining voltage and vape on it more if the voltage allows. Then I make a note of how many bottles (the juice bottle in the mod) I can vape, or up to what level the battery is still above the lower limit. So say for instance you have a 5ml swuuonk bottle and you can vape two bottles before reaching say, 3.5V, then you'd have a "built in" indicator. That's how I do it anyway.

    Unwilling to damage batteries, and wanting to be able to fine tune my vape, I turned my mechs into "semi? mechs" by including PWM, low battery shutdown circuitry, (for preventing operation when the cells reach 3V apiece), and short circuit protection. Mech purists of course will label me traitorous :giggle:

    1. yes of course, best way to vape

    2. when the battery starts draining you will definitely notice it, so simply put in a fresh battery and carry on. It's become second nature for me to put in a fresh battery in the mech and carry a spare with me when leaving the house

    on another note, the Requiem is an awesome little mech but be warned, it's pretty heavy in the hand

    1. Yes you can Vape on mech the whole day if you please
    2. The risk is you over discharge the battery and it may literally die (voltage drops too low) or even vent. So don’t do that!

    I think everyone has covered your questions @muller.s .
    Im not familiar with the mod but just check if the mod is a dual series or dual parallel battery configuration.
    1. Yes mech ADV - Nothing wrong with that as long as you are happy and staying off the cigarettes.
    2. For 1 battery -
    I=V/R (Im assuming a coil of 0.2 Ohms)
    so 4.2V/0.2Ohms = 21A
    for a flattish battery 3.6V = 18A
    Ideally you want to have a 20% safety margin so if you are vaping off one 18650 i would look at a 30A cell etc.

    The advice from @Viper_SA is spot on! I use ml vaped as an indication of battery life but this is years of use in my case. You will know when the vape is not satisfactory anymore! For some of us we feel the drop at 3.8V on a mech for others around 3.6V. (The vapour is just too cold and it feels flat)

    Lastly, when chain vaping, a battery first needs to overheat before thermal runaway occurs so if the mod is extremely hot when vaping - check batteries! You will find that the mod gets too hot to hold if the batteries are taking serious strain.
