I got to introduce a friend to the EVO this weekend. He is in love.
As we were enjoying the process and the effects, we got to discussing the intricacies of this particular vape, how cool the HT is, the design, how it can invert, why the ELB is so freaking great, understanding how he combusted one time - all sorts of fun discussion.
We got to discussing the heat up time and it spawned a few questions on the heat up time and process and what is actually going on there with the green light and the unit actually being ready to use.
If we let the unit cool off and turn it on to 1PM and pull a hit as soon as it turns green, there is wispy, DELICIOUS vapor there. If we then walk away from the EVO for 10 or 15 minutes, we come back to that same 1PM setting and get some nice thick vapor, still delicious. I think we have discussed that that is a result of the thermal mass being built up - but what does that actually mean?
Now that I have been thinking on it, it makes me wonder if the temperature is rising internally (as the unit gets all that insulation saturated with heat) or if the path that the air passes through is up to temp for a wider area. If it is simply wider, then I think it allows the air passing through to get to the right temp easier, as there is more exposure to THAT temp. If it is getting hotter, then I would think it is equalizing to a temp based on intake air temp > hot spot > happy medium between the two. I would hazard to guess that the latter of those two potentials (there may be more possibilities that have not hit me) would provide a less accurate interface - but I am not sure that matters (at least not for me, where this is pretty much all entertainment, not medical).
TL;DR - Once the unit is fully warmed up - be it via turbo mode or 10-15 minutes on, is the heated air path larger or hotter (or both) than at the initial green light?
FWIW, this is curiosity - performance is excellent.
