Regulated mod vs mech mod: vv/vw: istick 50w question

[jj6404]

So I'm thinking about the istick 50w able to fire down to 0.2 ohms and up to 50w and just thinking why that would even be desirable.

I hope I'm just missing some science here and someone can enlighten me but according to ohms law on a mech mod with a fresh battery I'll be hitting upwards of 80 watts with an atty with a 0.2 build. So I'm wondering: what's the point of vaping a 0.2 build on the istick 50w at 50 watts? Wouldn't it be underpowered for that setup?

No point at all. A typical 22 gauge, 0.2Ω dual parallel RDA build at only 50 watts will have a very cool heat flux of only 138 mW/mm2. The same build on a fully charged mech will have a nicely warm heat flux of 242 mW/mm2.

To obtain the same heat flux with a 0.2Ω/50 watt power supply, you'd have to use thinner wire, which will reduce surface area.

At 0.2Ω... the only VW regulated mod worth having, if you're used to a mech... would be something at 150 watts or better.

Actually the coils with resistance below 0.5 ohm on mechanic mods make no sense. The total power loss on all elements of the circuit can be about 50% at 0.2 ohm. Below you can see how it increase with lowering resistance:

With the same 0.2 ohm coil on vv/vw mod total loss will be maximum 10-15%.
