FNIRSI FNB-C2 2-IN-1 USB-C tester Power Delivery 3.1 EPR

The FNIRSI FNB-C2 is a 2-in-1 USB-C tester for analysing power delivery chargers and USB-C cables. It measures voltage, current and power with high resolution, supporting 4 to 50 V, currents up to 6.5 A and output power up to 240 W. With Power Delivery 3.1 EPR support and detection of popular fast-charging protocols such as Quick Charge, UFCS, Huawei FCP/SCP and OPPO VOOC, it helps you check compatibility between a charger and a device.

The tester reads the data stored in the E-Marker chip of USB-C cables, including cable type, length, maximum power and data transfer rate. Its two sampling modes let you examine power supply stability and ripple. Data logging for up to nine hours, along with automatic calculation of capacity and charging efficiency, supports evaluation over longer periods.

The 1.54-inch colour TFT display shows all readings clearly and rotates automatically. The tester works with Windows and macOS without additional drivers and weighs only 83 g.
