Another newbie shopping for his first vape I'll try and make it quick. I didn't quite find an existing topic like this. I'm looking for the "cleanest" vaporizer experience as possible. My wife is a nurse and hates my smoking habits. With such diverse vape technology out there, I am done combusting and ready to invest in the cleaner vaping lifestyle (which she is on-board with). I've lurked this and other forums for a while and have a few vapes I'm interested in. I'm probably unlikely to find scientists or doctors on here, but how clean/safe are those vapes that use the rechargeable NiMH batteries vs. those that use Li-Ion, or even other stuff I've seen (ceramic heating element, "wire", etc.)? Are there not byproduct or other harmful fumes that could be present when breathing in the vape from these batteries at such high temperatures? Ultimately, my criteria comes down to: "Cleanest/healthiest" experience, as close to zero chance of combustion possible (no butane) Use with dry flowers, (no oil or goo or wax) Portability would be ideal Solid, reliable construction and/or warranty (glass path, no plastic)- I will NOT buy a vape "Made in China" Thats really it. I don't smoke a ton, so I don't mind if it meticulous to clean. Learning curve is fine. I'm just ready to not have to spark up a lighter and kill my lungs any more. I'm not concerned about clogging. I don't need it to be the most amazing flavor or dense clouds or the ability to knock me on my ass. Budget isn't an issue either. I've come minutes from buying the Firewood 2.1, but just dont know about the NiMH battery "cleanliness", and have read instances of combustion with how hot it gets. I, like everyone have looked at the Pax. Of course everyone here loves the Solo. I considered the Firefly but read that combustion happens from time to time. Then there's the Ascent or Pinnacle Pro. Any "health-nut" vape-ers out there help a guy out? Very much appreciated!
