Accurate analysis of power supply parameters, support for the latest fast charging standards and extensive diagnostic functions make the FNIRSI FNB-C2 a valuable tool for electronics engineers and service technicians. The device allows you to analyze power parameters, USB-C cables and the charging process. It offers a wide measurement range of up to 240W, data logging, power quality analysis and the ability to read information stored in USB-C cables. The device is complemented by a clear HD display with automatic screen rotation and seamless integration with computers, without the need to install additional drivers.

Laboratory-grade accuracy for every measurement

The FNIRSI FNB-C2 uses an external 20-bit analog-to-digital converter (ADC), which ensures laboratory-grade measurement accuracy and allows you to display results with an accuracy of up to seven significant digits. The tester measures voltage, current and power with an accuracy of 0.000001V, A and W, so you can analyze even very small changes in the parameters of the power supply. It supports voltage from 4 to 50V, current up to 6.5A and power up to 240W, so it works smoothly with both traditional chargers and modern power supplies with a capacity of 100W, 140W or 240W. The safety of operation is increased by the built-in temperature sensor, which monitors the temperature of the device in real time with an accuracy of 1°C.

Full control of charging

The tester supports the Power Delivery 3.1 EPR standard using a special chip responsible for protocol communication, ensuring stable compatibility with modern chargers. It automatically recognizes and activates the most popular fast charging technologies, including UFCS, Quick Charge 2.0, 3.0, 4 and 5, Huawei FCP and SCP, OPPO VOOC and SVOOC, as well as VIVO VFCP. The device can also capture Power Delivery protocol negotiation data between the charger and the powered device, which makes it easier to detect compatibility issues. An additional function is the conversion of QC connection to PD, which helps improve compatibility between devices using different fast charging standards.

Detailed analysis of USB-C cables

FNIRSI FNB-C2 allows you to read information stored in the E-Marker chips of USB-C cables. This allows you to check the parameters of 3A, 5A, 50V, EPR, Thunderbolt 3 and Thunderbolt 4 cables, including their type, length, maximum power, data transfer rate and standard version. The tester also offers a simulation function for various cable configurations, from models without an E-Marker chip supporting up to 60 W of power, to cables that meet the 100W and 240W EPR profiles. Standard 24-pin USB-C plugs and plugs compatible with USB 4 Gen3 support bidirectional power flow measurement and allow cables to be connected in any orientation.

Professional power quality analysis

The device offers two power parameter analysis modes. The first mode allows you to plot voltage, current, and D+ and D− waveforms with a sampling rate ranging from 2 to 1000 samples per second, while the second is used for fast voltage ripple analysis with a sampling rate ranging from 20,000 to 2 million samples per second. The tester also displays the USB bus voltage (VBUS) waveform in real time, allowing you to assess the stability of the power supply in the frequency range from 20 kHz to 2 MHz. The recording function allows continuous recording of voltage and current waveforms for up to 9 hours, and the recording interval can be set from 1 to 120 seconds and the start and end conditions of measurements can be specified.

Data to help evaluate performance

The FNIRSI FNB-C2 records measurement results in ten independent statistical sets, including capacity, energy and operating time. Based on the collected data, it automatically calculates battery capacity and charging efficiency, facilitating the evaluation of the performance of power supplies, external batteries or cells. This solution allows convenient comparison of successive measurements and monitoring of parameter changes over a long period of use.

Easy-to-read display and convenient operation

The 1.54-inch color TFT-LCD display with a resolution of 240 × 240 pixels provides a clear view of all parameters. The built-in gravity sensor automatically rotates the image in four directions, ensuring that the display remains easy to read regardless of the orientation of the device. The tester works with Windows and macOS computers, there is no need to install additional drivers, so you can easily expand its functionality and update the software, as the device is recognized as a USB flash drive. You can also adjust the screen brightness, auto-dimming time, color theme and interface language, and quickly restore factory settings if necessary.
