Getting an equivalent vape from regulated mods

[dw75]

I currently vape 0.5 ohms on a mech mod. With a full 4.2 volt charge, that gives me 8.4 amps at 35 ish watts. (Then, there's the inevitable voltage drop and battery sag.) I'm trying to figure out if it's possible to get an equivalent vape on a regulated mod without sub-ohming.

So if my math is correct, to get an equivalent vape using a 1.3 ohm build, I'd need to be around 92 watts? (1.3 ohms at 92 watts = 8.4 amps)

Does that sound right? Is there any real safety advantage with this kind of set up? Or should I just raise up the ohms some (0.8 ohms at 56 watts gives the same 8.4 amps)?

I know that my sx mini has a way more powerful punch at 60 watts on my .25 ohm coil than a mech does with the same coil.

Having a in-line 510 volt meter helps, I got mine from Fat Daddy Vapes. I had to do this recently when I moved from mech to DNA40. The mech setup on the volt meter was pushing about 3.35 volts into my Origen V2 w/ dual vertical 26g coils @ 0.4 ohms. That's using a freshly charged MNKE 26650. Using ohms law, that gave me 28 watts, which translates pretty well on the DNA 40, and of course you get 28 watts all the time, rather than gradually decreasing wattage on a mech mod as the battery drains over time.

As far as trying to translate different coil builds, I use the Heat Flux figure on the Steam Engine page. That gives you an estimate of how hot the coil will get, so if you have to change builds, adjust your figures until you get to a figure that works for you. My preferred range is 110-120 mW/mm2. There's a little icon that changes color depending on the heat flux level.

The equivalent vape would be the same power and wire surface area no matter what the resistance. NOT the same current. For example 2 ohms would be 8.4 volts and 4.2 A (choosing an easy number) for 35W. That could be the same dual coils switched from parallel to series.

(Although you probably don't get 4.2 volts out of the mech for more than 2 seconds.)

The reality is closer to 3.5 volts.

Thanks for the feedback guys. After reading this and doing some additional research, I'm still trying to nail down the numbers but I think that if I go with the IPV2s (which upgrades to 70w) I should be good. I'll just have to play around with the builds.
