First, you will notice a different format than my previous tests. Today's test represents about 9 solid hours of testing, it takes time to figure out how to insert the tiny probes in those tiny cartridges, and still be able to actually vape the device, lots of trial and error. Anyway, it would have added another hour or three if I would have included all the pretty pictures and graphs. Those of of you who have followed along are aware of the methodology and the equipment I use. If you are just joining the party, please view this blog entry for details on how I am performing my testing.
Test Porn:
The way I rigged this particular atty was I heated a sewing needle red hot and made a tiny hole in the tank to slip the probe through. Then I inserted the probe inside the coil.
The results of the test show representative temperatures, when using a VV or VW device, for 3 different stock coils on the Vivi Nova 2.5, while possibly similar they DO NOT represent any other atty or coil.
- High temperatures are definitely possible without tasting anything bad.
- Chain vaping SIGNIFICANTLY increased temperature
- Wick saturation could be very finicky, if wick wasnt saturated it SIGNIFICANTLY increased temperature. It is IMPERATIVE that you do the swirl, or genny tilt, or some method to make sure each and every hit starts with a fully saturated wick.
- Tank level had significant affect on temperature, presumably related to wick saturation
- Low mass of coil allowed almost complete cool down in 1 minute, so wait at least a minute between puffs.Chain puffing is VERY bad, high temperatures are almost assured.
- Making voltage adjustments (on the Provari, might not be applicable to other mods) did send voltage to the mod while adjusting, so if you made an adjustment and instantly hit it, it was the similar to a chain vape, ie high temp.
- VW hits were much more consistent from hit to hit, where temp on VV varying a lot more at the same settings.
All of that being said, I do remind those who are interested in the safest vape possible, that these devices are NOT the best choice.
Lets set the controversial Wang Study aside for a second, though I still believe there is something to it. Our own Dr Kurt PhD, @Kurt here on ECF, who is very much an emissary for vaping, has clearly shown that Gen 2 (ie top coil), and some Gen 3 devices, are not the best choice.

at ANY power level on Gen 2 devices!
To each their own vape, having the information to make informed decisions is good too!
