Features: Brand new and high quality The high-performance main control chip adopts the VL805 USB3.0 high-performance main control chip, making the operation more stable, compatible, and the product performance is greatly improved. Uses an on-resistance power MOSFET to replace the rectifier diode, so it can reduce the loss of the rectifier Improve the efficiency of the DC/DC converter to meet the needs of low voltage and high current rectification. Small size, large current. Low loss alloy powder die-casting, low impedance, no lead terminal, small parasitic capacitance, solid and firm structure, precise product, long-lasting anti-rust. For multi . For Windows XP, Vista, 7 (driver installation required), for Windows 8 10 system comes with driver.
