| That is surprising to me, considering the sheer number of phones/tablets/laptops on every flight. Does anyone maintain a list of incidents? |

| Phones, tablets, and laptops are not sold in bodegas, designed to be disposable, and thus made as incredibly cheaply as possible. The high end vapes use huge amounts of current to the point that vape users will specifically seek unprotected cells because the protection circuitry adds a slight bit of internal resistance. So then the unprotected cells can then short out in their bags or otherwise be damaged and fail when the vape electronics fail... |

| ▲ | cosmic_cheese 4 days ago | parent [-] | | I think many don't appreciate just how horrifically cheap and dangerous some of this stuff is. Not just vapes, but things like charging bricks too. I'm generally not a proponent of draconian regulation but I firmly believe that any electronics handling substantial voltage not approved by UL or similar should be rejected at the border. It's all dangerous and incentive to manufacture it needs to be curbed. | | |
| ▲ | john01dav 2 days ago | parent [-] | | I have seen things approved by those sort of organizations that were extremely dangerous, such as a listed fire alarm that when installed has a significant chance of becoming silently deactivated. With that said, it can be even worse when it isn't listed. |

| I can't imagine that the QA process for vapes is better than even the _super_ budget tablet or phone, though. |

| ▲ | joecool1029 4 days ago | parent | next [-] | | It's not even just a QA thing, consider the use case: A sub-ohm vape head is basically almost shorting what is often a unprotected lithium ion cell (18650 or whatnot). Phones meanwhile are full of temperature sensors, battery pack in the phone has some kind of firmware/monitoring, board on the phone has a charge controller. There are plenty of good cell manufacturers that won't have problems in this current dumping situation (and will have certain passive protections like a CID to cut the current if it gets too hot). Problem is people like cheap and there are sketchy knockoff cells without those protections and shoddy manufacturing quality. If there was anything recently that forced the change it was probably the CT scans of the Haribo battery packs showing the cathode/anode overlap. This sort of thing should spook airlines. Do we still have UL? Do they test battery packs? Why not make it a requirement to only fly with ones that pass lab testing like UL? | | | |

| E cigarettes work by shorting the battery releasing a lot of instantenous heat. Their safety controller firmware are often of ... Dubious quality. It can happen quite often that the cigarette doesn't stop shorting the battery and catch fire as a result. Making fire is literally their function unlike a laptop. Combine that with basically unregulated and semi illegal supply chain and it becomes a recipe for disaster |

| ▲ | evelant 3 days ago | parent [-] | | AFAIK that's not really true, at least of modern vapes. Their function is not to "make fire", it's to heat a metal coil to a specific temperature at which propylene glycol and vegetable glycerin will aerosolize which is far lower than ignition temperature. Most modern vapes also use controllers with a feedback loop that pulse power through the coil hundreds of times per second to maintain the ideal temperature and desired power throughput. That being said there are definitely crappy and diy devices that unsafely dump huge current through devices but AFAIK modern devices generally don't do this because it's a bad user experience (burnt taste, too hot, ruined cotton absorber, etc) -- regulating the power is what users want so it's what devices do. |
