Seems to be a common thread there…
All three very recent mods, and two of the three brands are “up and comers” (Smoant & Vaporesso). The ones I have seen it be “occasionally iffy”, to downright questionable, are on average 2+ years old.
My Cuboid 150w has always been reliable (but primarily from an “it works” (and mainly in power mode these days, because I got tired of it bouncing around, or even out of TC mode) standpoint). It’s always frustrated me that the impedance never truly stays rock solid. (There’s a lot of fine details that I’m not going into, but that’s because it’s so much trouble, and time consuming to go into). I can deal with TC being a bit off, as long as we’ve got the ability to adjust for TCR.
I’ve also experienced the same with other (older) devices. So you guys may be reaping the benefits of joining the vaping party later… Much like I enjoyed missing the cartomizer/clearomizer days of that which preceded me. chuckles
At any rate, I experienced the same poor “reading skills” with my old Sigelei Spark 90 (2015 model?), the Sigelei Fuchai 213 Pro (Dan_the_Man’s unit, early 2017? Model), the Eleaf products (I’ve tested the 40w, 50w, and 100w models), with the worst being the Smok Alien’s, understandably so (given the “construction” of the 510 assy.).
That’s so far been one of the bigger draws (and reasons supporting the accuracy of the DNA devices. The fact that you can test for and equally importantly adjust for the offset created by the gauge of/length of/quality of the additional margin of error introduced by such factors. (Chipset abilities not withstanding of course)
That’s what really caught my attention when I was testing the operation of the Vaptio N1 (VM’s). I had just used it on my Cuboid (where it read 0.22 ohms, normal for about 3-4 day’s use), and it was still warm when I put it on the N1. When I popped the 2 batteries in, it instantly read the impedance as being 0.18 ohms.
I hit it a couple times, and it still read 0.18. that definitely made me “stand up and take notice”. I first thought, ok, are they just plugging the first reading into “memory” (in some way)? Or have things finally advanced enough in “run of the mill vaping chips” that we could finally start to see the playing field leveled (at least among the IMO “respectable” manufacturers, and the DNA/YiHi chips)?
I’m hoping that “access” will begin to open up soon on this front, as I may have an opportunity opening to put much more recent gear through the paces. But I’ll have to see how that plays out.
If Aspire has improved their chip (or choice of chips), that’s a positive sign. If Smoant and Vaporesso as well, are indeed accurately reading things, and maintaining those readings (like Vaptio seems to be) then possibly, it’s a good indicator that a trend is taking hold (at least among the first tier manufacturers) and that there’s going to be some truly wonderful things coming our way in the 2018 regulated domain!!
And that excites me!!
