FNB-C2 PD3.1 USB-C Tester 240W, Bi-Directional, E-Marker Reader | 20-Bit ADC, 7-Digit USB Cable Tester, 4-50V/6.5A, Real-Time Graphs, PPS, QC2.0/3.0, Cable Resistance, PD Trigger, PC Software

FNIRSI FNB-C2 is a USB-C power tester designed for real-time power monitoring and electrical measurement. It supports USB PD 3.1 protocol and covers a 450V voltage range with up to 6.5A current detection, enabling power monitoring up to 240W for chargers, laptops, and USB-C devices. It features a 1.54-inch color display with real-time Curve View, allowing users to observe voltage and current changes during charging and discharging in a clear visual format. Built with a 20-bit ADC chip, the device provides precise measurement of voltage and current, delivering stable and consistent data for general testing and troubleshooting needs. The protocol trigger function supports PD 3.1, PPS, and QC 3.0 standards. It can read E-Marker cable information and evaluate cable performance by measuring internal resistance, helping users compare different USB-C cables. The device also supports bi-directional current measurement and battery capacity estimation. Offline curve recording and multiple groups of energy statistics (Wh/Ah) help users track power usage and charging cycles over time. For convenience, the FNB-C2 includes a gravity sensor for automatic screen rotation and a HID interface for PC software connection. It supports real-time data logging and external power supply, suitable for continuous testing and monitoring use.
