36 watts measured how? if you are assuming 36 watts just by doing the math then you may be surprised to know that what you think is 36 watts can in reality actually be quite a bit less. just doing the math calculating voltage of a fully charged battery doesn't take into account voltage drop of the mod and voltage drop of the battery as it discharges too, so a lot of times guys who think there vaping at 36 watts may be very surprised to find out that what they thought was 36 watts winds up being closer to maybe 25 watts in the real world once these losses come into play, and goes down from there as the battery discharges. the losses become greater the higher you go, so if by math alone you arrive at 18 watts you may actually be hitting 14 or 15, but at 36 the losses are usually quite a bit higher.
the dna20 is limited to 20 watts, but the dna has very low voltage drop and this is a lot closer to delivering an actual 20 watts real world, and the good part is that it will maintain this level of delivery all through the batteries usable capacity, so as an example, right now I'm running a .8 ohm coil at ~4.1v regulated, so it's equal to a .8 ohm coil with a just off the charger battery in a high end mod with very little voltage drop, but, unlike the high end mod that is going to slowly go down and down in power as the battery is used up, this one instead will maintain this level of power delivery throughout almost the whole batteries capacity, so you get the vape of a high end mod with very low voltage drop with .8 ohm coil on a freshly charged battery even as the battery depletes, none of that stronger vape right of the charger and then dropping a bit, and then having to swap out half dead batteries to regain a strong vape, it's regulated to give you that same fresh off the charger vape throughout the whole cycle, from fully charged to almost dead
so in reality my 20watt setting may only be at 80-85% the real world power level potential you may achieve with a fresh battery, but will maintain this throughout it's whole batteries cycle where yours will slowly drop down to, and then eventually below the level this mod can deliver by the time your battery drops below half way. numbers and watts all sound great on paper but real world delivery can deviate quite a bit from just what the math alone shows you, the dna 20 is rock solid stable regulated, yeah only 20 watts but that's about all a regulated mod can deliver at this time and believe me, it's not as far below where you are at as you may think. this mod has 2 tight solid brass contacts directly to the battery and the electronic switch inside is more efficient than even most of the highest end mods, don't let that 20 watts thing fool ya, this thing hits hard all the way from a fully charged to almost dead battery and in doing so really extends the usable range between charges, so a 15-20% less power potential at the very peak isn't so much of a bad tradeoff considering what it does bring to the equation overall.
