Teardown: Black Shark BRC02 Magnetic Wireless Charger with TEC Active Cooling — Southchip SC8723 and SC96019 Power Chain
2026-09-20 · Compiled by Best IT Parts from public industry reporting
Full teardown of the Black Shark BRC02, a 90.6g, 65.67mm x 21.89mm magnetic wireless charger that pairs 25W wireless fast charging with a TEC Peltier cooler — claimed to pull surface temperature down to 13°C — plus a turbo fan. Input is 5V/9V/12V/15V at 3A via USB-C (45W max), with 5/7.5/10/15/25W wireless output and a 7W cooling-plus-fan rail; measured draw was 14.68V/2.35A (34.53W) while charging an iPhone 17 Pro Max in 2-in-1 mode. The mainboard runs a Southchip SC8723 synchronous four-switch buck-boost converter (2.7-22V input, 10A inductor current limit, QFN22) and a JoulWatt JW5359 18V/2A synchronous buck (SOT23-6), while wireless power conversion is handled by a Southchip SC96019 Qi2.2 / WPC 2.2 transmitter SoC with integrated 12mΩ full-bridge MOSFETs and a 288MHz EPWM block. A Litz-wound coil, NPO resonant capacitors, a CRM resonant-cap switching MOSFET and an unmarked MCU round out the BOM. NTC thermistors on the Peltier cold side and the PCB prevent icing, and conductive grease bridges the TEC, PCB and aluminium mid-frame — a useful reference for active-cooling accessory designs.
