Generic USB Tester USB Voltage Meter FNB48 PD Trigger Voltmeter USB 3.0 Voltage and Current Tester DC 4-24V 6.5A USB C Multimeter PPS F

Description FNB48 Multifunctional fast charging protocol detector 1. Integrated USB-A, Micro-USB, Type-C interface, with 1.77-inch high-definition display, using external 16-bit ADC, PD protocol physical chip, real-time monitoring of voltage, current, power, power, capacity, charging protocol during charging, Curve aveform, etc. 2. No need to match the original data cable, you can also directly detect the charger protocol of OPPO, Huawei, OnePlus and other brands. 3. In any interface, by long pressing the return button, the screen can be hibernated, wake up by any operation, and charging at night will not affect sleep. 4. FNB48 uses the differential pressure method to measure the internal resistance of the cable, Use with constant current load, Easily detect the internal resistance of the cable. Features Voltage and current curve,real-time detection of voltage and current Low-speed voltage and current curve Low speed D+D-curve Record offline curve High-speed voltage ripple(AC coupling) Powerful
