    Hello all,

    I just have a quick question, I have been vaping for 3 years now after quitting smoking and so I have been fairly confident in my knowledge up until now.

    I recently bought the Nautilus 2 Tank which is great, it came with a 1.8 coil and a 0.7 coil. I previously vaped at 1.5 ohms at around 10 watts I believe it was around 3.9 volts, something like that.

    I was just wondering what is the minimum and maximum wattage/voltage to be vaping a 0.7 ohm coil at baring in mine I am a mouth to lung vaper.

    I find that even from 14 watts I am getting a comfortable vape but my volts is sitting at 3.2. With that being a jump down from the 3.9 volts I was vaping at before I was interested to know if it's unsafe to vape at too lower voltage, and if so is this too low? I heard a while back that going much over 4 volts heats up the liquid too much and releases unwanted toxins, so I like to vape at as low voltage as possible, but got me thinking if there is a too low voltage and if so what is the lowest for a 0.7 ohm coil.

    I would like to continue using the 0.7 ohm as it works really nice with my liquid and the nautilus tank.

    Hope to hear from someone soon.

    Have a great day,
    Jake

    I am MTL on 0.5 ohm coils. 80 watts is almost too much for me without temp control, 60 is perfect with 80vg/20pg 18mg juice. More pg means lower wattage Less nic means you can go a bit higher before it gets cough worthy harsh.

    you are using a tad higher resistance so, I'd start at 20 watts and go up by 5 watts until you get the volume and temperature of vapor you want.

    This is helpful thank you for your response!

    I should add that I use a 50/50 liquid at 6mg.... if anyone else has anything to say on this...

    20 watts seems nice, i'll have a play around based on your suggestion. I've just looked and at 50 watts this is 6.1 volts, is this not too much power as far as safe vaping goes??

    Simple answer, "Nope" there is no detrimental effects of vaping at lower watts/volts. If 14watts on a 0.7ohm coil is satisfying you, then 14watts on a 1.4 or 1.8ohm coil will be the same. There is no right or wrong answer here as there is no silver bullet setting for everyone, as everyone has different tastes. Now there is the fact of going to high can create formaldihydes, acrolien gas, and other not to healthy by products, there in lies the variable of the actual temperature at the coil, not the actual watts or volts, and the coils stay cool by evaporation of liquid into vapor combined with amount of airflow and the power being pushed to the coil. If the battery being damaged or put at risk at 3.2v compared to 3.9v, "No", the control board is pulling what available voltage charge the battery has, anymore over than what is needed, it is bucking the excess power away into the control board, if to little then if it has available a boosting circuit which pulls raw amps to convert to extra voltage.

    In either instance, the lowest absolute voltage before a battery is damaged is 2.5v per battery, in this charge state the electrolyte solution could pontentially dissolve the copper inside into its solution and cause microshorts internally, most mods shutdown or refuse to fire at lowest 2.8v per battery (example Smok Alien 220watt), the other side of the spectrum is the highest potential charge is 4.2 to 4.22v any higher than that, the battery could potentially vent or rupture. On most current devices programmed operation range is between 3.0 to 4.2v, what is being supplied generally doesn't relate to what voltage is available, nor if your mod displays them amps being reported are only the amps being pushed to the coils not what is being pulled to the battery. The 0.7ohm coils, I am assuming you are talking the Nautilus 2 coil heads, you are fine between 7 to 15 watts the 1.6/1.8ohm coils, 10 to about 25watts max the 0.7ohm coils.

    Wow, this response is perfect, thanks so much...!!!!

    This is exactly what I needed to hear. I realise to some, vaping a 14/15watts with a 0.7ohm coil, sounds like it may be too low, but for me I get a satisfying vape and a good taste, without putting stress on the battery and/or coil. Hopefully this will also make the coils last longer than the average person too.

    This is a fantastic answer and gave me the exact information I was looking for. Happy vaping sir/ma'am!

    The easiest answer to wattage is to just start real low and work your way up. When you find what is satisfying to you, that is all that matters. As long as you aren't getting it hot enough to burn the cotton(you will know it when you do...and it will taste awful), if you are satisfied at a lower wattage than normal, that is the spot for you. Nothing at all wrong with it.

    Welcome and glad you joined.
    Lets see, 10 vs 14 watts. You may have to choose which taste better and how much money you wish to sacrifice to vape at 14 or more watts.
    In General lower ohm coils/higher wattage vaping will:
    Heat The Coil Faster
    Produce More Vapor, can mute taste (coat mouth/build up)
    Drain The Battery Faster
    Use E-Juice Faster
    Produce A Warmer Tasting Vape
    Shorten Coil Life
    Shorten Wick Life
    May Produce Spit Back
    More PV Maintenance/Issues
    More irritation to non vapers (tends create more negative comments regarding cloud production)

    Just add that "safety" is about amps which is based on watts with APV's. Generally 60w per 20A battery, if it's an internal battery it simply won't let you do it if it can't. Ohms never tell you what watts range to use as its a factory coil you cant tell what AWG or how many wraps the wire is. Ex. you could get .5 Ohms with a ton of 22 AWG Nichrome or 5 wraps of 26 AWG nichrome... same Ohms but watts required for 22 AWG would be much higher.
