Most portable electronics today use some variation of lithium ion batteries, which when it becomes unstable can combust/explode if mishandled. However, devices generally have thermal management software and hardware, as well as multitude of other safety mechanisms like power management systems to handle charge regulation. Unless you intentionally puncture your batteries, they’re not likely to cause any problems on their own.
Sure. But the capacitors in the devices do make a pop and the fragments/shrapnels from the damaged devices depart from their physical location at pace that I would not be comfortable with.
If I’m dealing with a spicy pillow situation, the technical definitions as to whether or not something counts as an explosion is the last of my concern.
I guess the question I am asking is how do I know someone hasn’t placed a bomb inside as is now happening with other devices in the world? (See current news)
Until you dismantle your devices, you don’t know, but unless a terrorist state like Isn’treal wants you dead, they almost definitely don’t have bombs in them. It’s not something I’m the least bit worried about.
