Video Teardown: Xiaomi 22.5W Power Bank with Built-In Cable
2026-08-03 · Compiled by Best IT Parts from public industry reporting
This video teardown dissects Xiaomi's 22.5W power bank featuring an integrated USB-C cable, revealing the internal architecture of a mainstream portable charging design. At the heart of the unit is Southchip's SC2017A power bank SoC, which integrates charge/discharge management, protocol decoding, and battery protection in a single chip — a cost-effective solution widely adopted in volume production. The teardown walks through the PCB layout, cell configuration, and thermal handling, highlighting how manufacturers balance BOM cost with 22.5W fast-charging performance across PD and legacy protocols. A practical reference for power bank OEMs, battery pack assemblers, and B2B buyers evaluating proven SoC-based designs for private-label and wholesale portable charging products.
