I’m surprised we aren’t having more of these. People tend to bring their cell phones/laptops/tablets in the cabin with them, but there are so many suitcases below deck with battery-powered shavers, toothbrushes, vibrators, kids’ toys, and who-knows-what-else, all of which may have dropped multiple times over their life and have probably been fully charged before departure with a charger of unknown quality. Cheap hoverboards and vape pens have already been outed as fire hazards, but if even big-name reputable companies like **[Samsung](https://en.wikipedia.org/wiki/Samsung_Galaxy_Note_7#Battery_faults)** and **[Boeing](https://en.wikipedia.org/wiki/2013_Boeing_787_Dreamliner_grounding)** have trouble assuring good quality on the batteries they’re procuring for their products, then every battery-powered consumer electronic device in the cargo hold seems like one more roll of the dice.
