Part 8/12:
- Overcharging Experiments: Connecting a power bank to a power source beyond its rated voltage causes internal temperatures to spike, and smoke or combustion can occur. In one test, an unbranded device overcharged to nearly 5V (instead of 3.7-4.2V normal range), resulting in a fiery explosion.
These demonstrations underscore the importance of safety mechanisms within power banks, such as built-in overcharge protection and high-quality internal components. Devices lacking adequate safety features can pose serious hazards, especially in confined spaces like aircraft cabins or homes.
