Feature: 1. 1.6mm PCB thick double‑sided sheet, sturdy and durable, 1.5 oz copper thick, have a long service time. 2. The whole process is sprayed with tin to ensure good current flow performance. 3. Increased stability, the input and output use high frequency low resistance capacitance, greatly reduce the output ripple. 4. The heat dissipation area is large, which can better maintain long‑term operation and is reliable in use. 5. Small in size and light in weight, convenient to carry and use at any time, very convenient and practical.
