Power Bank MOSFET Salvage

Teardown & Analysis

This lab was a teardown experiment: I cracked open a commercial power bank to inspect its internals and attempt to salvage its MOSFETs. The board was far more modular and complex than expected, with tightly integrated charging, protection, and boost circuitry. Although none of the MOSFETs were usable for my project, the teardown offered a clear look at how consumer power banks manage battery safety and conversion.
