Overview 📝
The FNIRSI FNB48S BT is a professional-grade USB multi-tester designed for deep analysis of charging systems. It features a stunning 1.77-inch high-definition TFT LCD and a dedicated 16-bit ADC for extreme precision. Unlike basic testers, the FNB48S can “trigger” fast-charging protocols, allowing you to manually test the maximum output of a charger. With integrated Bluetooth, you can monitor real-time charging curves and log data directly to the official Android app.
Key Features ✨
