Product Details ①Numerical control voltage & current (current limiting) settings with precise display: Voltage step 0.01V/0.1V, current step 0.001A/0.01A, ensuring accurate adjustment and monitoring for device operation. ②LCD multi-parameter display: Shows input voltage, output voltage, temperature, current, capacity, and time in real-time. USB female output enables easy connection to USB-powered devices like fans. ③Screw-free quick wiring terminals: Press-type wiring and wire pulling eliminate screw usage, allowing fast and hassle-free setup. ④Smart fast charging decoy: Addresses USB input port power shortage, supports mainstream fast charging protocols (QC2.0/3.0, FCP, SCP), and offers non-deception or auto-deception mode options. ⑤Versatile 15W, 2A power output: Suitable for fan speed regulation, desktop power supply, adjustable chargers, router power supply, etc. Output voltage (1-30V) and current (0-2A) are adjustable, with short circuit protection to prevent damage. ⑥USB charging compatibility with multiple protections: Adjustable charging voltage/current (constant current, anti-backflow) meets most battery charging needs, with short circuit, over-current, over-temperature, over-voltage, and charging anti-backflow protection.
