FNAC-28 USB tester - Bidirectional high current detection: Bidirectional current measurement up to 6.5 A. USB-A and USB Type-C interfaces are supported, enabling accurate monitoring of both power supply and load. Provides detailed data to support analysis and decision making. - High-precision measurement chip: Uses an external 16-bit ADC to ensure accurate voltage and current data. This reduces measurement errors and enhances the professionalism of test results. - Multi-functional data analysis: Includes battery capacity testing and stores 5 data sets. Supports curve display, waveform pause, and an adjustable time base range for careful observation of trends and performance. - Fast charging protocol support with automatic detection: Compatible with QC2.0/QC3.0, FCP/SCP, AFC, VOOC/WARP, SVOOC 1.0/SVOOC2.0. All supported protocols are automatically detected to meet a variety of testing needs. Use scenarios - Verify charger and cable performance: Connect chargers and cables to assess real-time power delivery, current, and energy consumption. Use the curve display and time base to confirm stable charging behavior and identify bottlenecks. - Evaluate power banks and devices: Test battery capacity and monitor how devices draw current during charging. Save up to five data sets for comparison and documentation of charging performance over time. - Debug fast charging compatibility: Test whether devices and chargers negotiate and trigger the appropriate fast charging protocol. Automatic protocol detection helps confirm compatibility across QC, AFC, VOOC/WARP and SVOOC standards. Note: The FNAC-28 is designed to provide reliable, real-world data for power delivery and charging performance, supporting USB-A and Type-C interfaces with a focus on accuracy, ease of use, and versatility.
