To achieve the repeatable experience of Replay, the board cleverly monitors a mind boggling array of parameters and records them. When the mode is activated, the board balances all parameters to deliver the same result as the vape that’s just been recorded. It will compensate for any changes in variables, delivering more or less power more quickly or more slowly (as well as tweaking all sorts of other things along the way) depending upon the environment and status of the atomiser at any given time. So, if you Replay a vape you took whilst in a very hot kitchen, then went outside into the snowy freezing cold, the board will compensate for that temperature change and deliver the boost of power necessary as fast as possible to bring the coil up to the temperature it was in the kitchen when you took that awesomely tasty sweet spot vape. This may be an extreme example, but it illustrates how having a large headroom of power available to yield instantly satisfying results is definitely a desirable quality. And of course, with Replay’s monitoring of the coil’s status, a dry hit from the surge of power won’t be happening. It’s genius. Absolute vaping genius.
Alongside the benefit of power headroom in Replay mode, there are also other reasons why having a high wattage capacity is something desirable by certain groups within vaping. Although the statistical majority of vapers will vape below 100 watts, there are many who prefer to use high-mass complex clapton coils, yielding voluminous quantities of vapour at high temperatures. This is the case in the PWM and Series mods scene, wherein vapers use higher voltages (thus drawing less amperage from their cells) to push large amounts of power to coils which take a comparatively long amount of time to “ramp up” to cloud producing temperature. In these instances having a board and device capable of instantly driving huge amounts of wattage to big, chunky clapton coils is definitely going to be a major factor in device selection. Some vapers just need that power to warm their coils up. To many it’s hard to believe, but some folk just love a vape way over the power levels provided by most mainstream devices for vaping.
There’s also a couple of other technical reasons why having that much power available is actually rather a boon. The DNA 250C will have different wattage output limits dependent upon how many cells (in Series) it has available to use. So with 2 cells (2S = 4.4v) it will output 200 watts; 3 cells (3S = 12.6v) is 300 watts; 4 cells (4S = 16.8v) a whopping 400 watts. The advantage that having the voltage of 4 cells available gives is that of efficiency (albeit marginal) and also less stress being placed upon the cells due to current draw (Amps).
Firstly, it is generally considered that it is more efficient to “buck” down voltage than it is to “boost” it. Although the gains are minuscule, it still adds to the overall efficiency of the board (which is a remarkable 98%) being able to utilise a high voltage to step down to the one required to provide your desired wattage output. Having the voltage of four cells available as opposed to two is obviously going to give longer time between charges, but is also going to result in less power lost delivering the required voltage than with a fewer number of available cells. It’s just a more efficient way of delivering the power to the atty than boosting the voltage. Tiny, but the difference is there nonetheless.
Secondly, by drawing a lower current from your cells, less stress is being placed upon the individual cells, thus increasing the overall life time of the cells, and also helping to reduce the chance any problems that can can result in thermal runaway occurring. Obviously it’s not a reason to neglect good battery hygiene, but it’s definitely good to have that extra margin of safety. Running a build that needs 100 watts is always going to draw less current from each cell using the voltage of 4 cells in series as opposed to two.
So what can we learn from the above then? In simple terms, more volts available is more of everything that we as vapers we want. A regulation board in a device with enough cells, capable of providing huge amounts of power is desirable in several different ways. We can use “Replay” more effectively; we can vape mahoosive coils for outrageous cloudage easily; through increased efficiency we can vape for longer, and we can do so within greater margins of safety. Even a tootlepuff 12 watt vaper like me can benefit from a mod capable of giving 388 more watts than I need. With a 4S DNA 250C I can’t even tell you how long it is between charges. I seem to only be able to judge it by the length of my beard. “Need a shave? Probably should charge the mod as well then” seems to be the way that it goes for my particular vaping style.
