Not many details offered. Would have to be a perfect storm to cut the carotid artery.
Absolute tragedy - Poor lad was only 24. I didn't appreciate the biased reporting the original news article - showing a picture of a low capacity e-cig with venting that is less dangerous battery-wise than a laptop. To add insult to injury, add some hype about the number of teenagers vaping these days at the bottom ....
Most stores here won't go near mechanicals anymore. For anything. No rebuildables either. I can't say I blame them. There is a lot of liability. I have seen people who know about ohms law running 18ga. 4 wrap dual builds on 18650 VGODs
I have worked with some really industrial high voltage/current kit in my time and it has taught me to have a very healthy respect for high current devices. Anyone running the above setup has got a death wish - you are looking at ~ 100A current at 4.7v running 470W. That is higher than the main fuse-board rating in a UK household (Generally 60-80A) and what your average MIG welder will utilise. All it takes is 1000th of that current to be fatal. So a poor 18650 used under these circumstances will very likely fail, and fail bad.
Looking at the quality of some atty's, personally I'd be very wary of using a mech unless I was 100% convinced of the atty, mod and battery provenance/quality. Even then, if the switch failed closed (and I've replaced many of them in that state in my time), you've got a problem.
If I ever feel the urge to reach the vaping heights of a small electric fire, I'll buy a Steamcrave or something with decent protection in it. Not that I'm dissing people who use mech's, but you really have to be very diligent. As this tragedy shows, you have to be right 100% of the time - the kit only needs to be wrong once.
Who tells someone with asthma a special vape pen will help?
I can sort of get that, PG is used in nebulisers and as a kid (I had really bad asthma) my mother used to get me to stick my head over a bowl of steaming hot water "to help open up my tubes". According to the British Lung Foundation, swapping cigarettes for an e-cig can improve your symptoms of lung conditions like asthma and COPD. [
There's more evidence than ever that e-cigarettes are safer than smoking]. Both my BIL and I have lung conditions, and we have found that to indeed be the case. Qualifying that, we are both DTL vapers, and neither of us had any luck with MTL pen devices whatsoever.
