QC4 · PD3.1 · Soft DASH Overview
The FNIRSI FNB58 is the top-of-range USB power meter and fast charging protocol tester in the FNIRSI lineup. Powered by a dedicated 16-bit external ADC and PD protocol physical chip, it measures up to 7A and 28V with 6-digit precision across USB-A, Type-C, and Micro-USB interfaces — all displayed on a crisp 2.0" full-color IPS HD screen with auto-rotating gravity sensor.
Beyond measurement, the FNB58 is a full protocol trigger and analyzer: it can actively trigger, detect, convert, and even emulate fast charging protocols — including Soft DASH cable simulation for triggering VOOC/WARP without a DASH cable, and QC2.0 → PD2.0 protocol conversion for powering PD devices from QC chargers. PC software and optional Bluetooth app (Android) complete the package.
Key Features 🖥️ 2.0" IPS HD Display Full-color, ultra-wide viewing angle IPS panel — the largest and clearest in the FNIRSI range. Sharp and readable from any angle. ⚡ 7A High Current Rating Handles up to 7A — suitable for laptop charging, high-power power banks, and demanding 65W–100W USB-C scenarios. 〰️ 4Msps Ripple Sampling Highest ripple sampling rate in the lineup. AC-coupled high-speed ripple measurement with Excellent / Normal / High / Inferior quality thresholds shown on screen. Exclusive 🎭 Soft DASH Emulation Simulates a DASH cable chip — trigger VOOC/WARP charging using only a standard Type-C cable, without needing a proprietary DASH cable. Exclusive 🔄 QC2.0 → PD2.0 Conversion Converts QC2.0 charger output to PD2.0 protocol, enabling PD-only devices to fast charge from a QC charger. Adjustable power output. Exclusive 🍎 Soft Apple Emulation Simulates Apple cable behaviour for triggering Apple fast charge modes without an original Apple cable. 🔬 16-Bit External ADC Dedicated 16-bit ADC + PD physical chip for lab-grade measurement accuracy. 6-digit display (0.00001 V/A/W). 🏗️ CNC Metal Shell Precision-machined metal enclosure. Compact at 42×13×82mm — built for bench use and travel. Feels premium in hand. 🔌 3 Interface Types USB-A (5-pin high-current), 24-pin Type-C, and Micro-USB — test virtually any USB device, charger, or cable combination. 📡 PD Monitor / Listener Passively sniff PD communication between a charger and device. View parsed and raw PD packets in real time. PD switch isolates communication for safety. 🌀 360° Auto-Rotate Display Gravity sensor keeps the readout correctly oriented at any insertion angle. 4 supported screen directions. 💻 PC Software + BT App Driver-free PC software for data logging, waveform export, firmware updates, and protocol triggering from PC. Optional Android Bluetooth app (BT version only, iOS not supported).
