FNIRSI FNB48P BT is a universal USB measuring and diagnostic tool that helps you quickly verify the behavior of chargers, cables, and powered devices. With support for multiple ports (USB-A/USB-C/Micro USB) and high current up to 6.5 A, you can easily measure both standard and more demanding charging scenarios, including USB Power Delivery.
The tester detects and verifies popular fast-charging standards (e.g., QC, PD, AFC, FCP/SCP, VOOC/DASH/WARP, SuperVOOC, etc.) and also offers smart cable diagnostics—including PD e-marker detection and cable internal resistance measurement to assess losses and quality.
The large 1.77" HD display shows key parameters and graphs (voltage/current, logging, power ripple), and the gravity sensor enables automatic screen rotation for comfortable reading. Logging of up to 10 data sets and battery capacity calculations make long-term testing easier; Bluetooth and the PC interface expand options for analysis and saving results.
