The primary stage feeds roughly 310V–340V DC (depending on local AC input mains) into the primary winding of the high-frequency flyback transformer.
Heavy-duty, fast-recovery diodes smoothly output a baseline 5V DC rail.
If you are looking into a specific repair or modification for this charger,g., dead completely, port failure, display glitching)
Based on standard power supply schematics for this series, the internal layout is divided into high-voltage (Primary) and low-voltage (Secondary) sections.
For the most accurate component-level repair, identifying and reading the datasheets of the main controller ICs is the next best step. Good luck! Wlx-896b Schematic

The secondary 5V rail splits across the 6 USB-A output ports via a parallel distribution path. The primary stage feeds roughly 310V–340V DC (depending
The is a popular multi-port USB charging station (often branded under names like Aisibei or Yisheng ) known for its LED display showing real-time voltage and current.
A small 8-bit MCU (often unmarked or COB "blob" chip) handles the display logic.
Technical schematics and wiring diagrams are typically detailed in comprehensive manuals, such as the WLX-896B Schematic Overview available on Schematic and Wiring Overview
A typical schematic for this controller includes several critical connection points: Power Input: Frequently paired with graphic panels for visual data

"I'm extremely impressed with the Wlx-896b Schematic! As a electronics enthusiast, I've been searching for a reliable and detailed schematic diagram for a while now, and this one exceeded my expectations.
: The AC input features a glass fuse (typically 2A to 3.15A slow-blow) placed in series with a metal oxide varistor (MOV) to suppress high-voltage spikes. A common-mode choke coil and an X2-rated safety capacitor suppress electromagnetic interference (EMI).
A Resistor-Capacitor-Diode (RCD) network sits parallel to the transformer's primary coil. This layout dissipates leakage inductance voltage spikes that would otherwise fry the switching MOSFET. Stage 3: Secondary Rectification & Smart Power Regulation
