Shop name:Chong Qing Shuo Yue Ke Ji You Xian Gong Si The high-performance main control chip adopts VL805 USB3.0 high-performance main control chip, which makes the operation more stable, , and product performance is greatly improved. Synchronous rectification uses an on-resistance MOSFET to replace the rectifier diode, so it can reduce the loss of the rectifier the efficiency of the DC/DC converter to meet the needs of low voltage and high current rectification. Low-loss alloy powder die-casting, low impedance, no lead terminal, small parasitic capacitance, solid and firm structure, product, long-lasting rust prevention, small size, current. Multi-system compatibility with Windows XP, Vista, 7 (driver installation required), Windows 8, 10 system comes with driver.
