Fnirsi FNB-C2 Voltage Tester
The FNIRSI FNB-C2 is a professional USB tester for analyzing power sources, USB-C cables, and
charging processes. The external 20-bit ADC converter offers high precision and display with up to
seven significant digits. The tester measures voltage, current, and power, with a range of 4-50V, up
to 6.5A and 240W. The built-in sensor monitors temperature with an accuracy of 1 degree C.
Compatibility with Modern Charging Standards
The tester supports Power Delivery 3.1 EPR and protocols such as UFCS, Quick Charge 2.0/3.0/4/5, Huawei FCP/SCP,
OPPO VOOC/SVOOC, and VIVO VFCP. It can capture Power Delivery negotiation data and identify compatibility
issues. The QC in PD function allows testing devices with different standards.
USB-C Cable and Power Quality Analysis
The FNIRSI FNB-C2 reads the E-Marker chips of USB-C cables and displays information about type, length, power, and
transfer speed. It supports 3A and 5A cables, EPR, Thunderbolt 3, and Thunderbolt 4. It can analyze voltage,
current, D+/D- waveforms, and VBUS ripple. Recording can last up to 9 hours, and the data can be
used to calculate capacity, energy, autonomy, and charging efficiency.
