The FNIRSI FNB58 is a high-precision USB voltmeter and ammeter designed for comprehensive testing of charging protocols, cables, and power delivery systems. It serves as a sophisticated bridge between basic USB dongles and professional benchtop equipment, offering detailed real-time analysis across USB-A, Micro-USB, and USB-C connections.

Modern charging standards like PD3.1 and QC5.0 involve complex negotiations, making it difficult to diagnose why a device isn't charging at full speed or if a particular cable is at fault. The FNB58 solves this frustration by visualising the negotiation process, measuring internal cable resistance, and safely triggering specific voltages. This allows makers to verify charger performance and troubleshoot power issues without risking damage to microcontrollers or development boards.

Engineered for daily use on the workbench, the unit features a crisp 2.0-inch wide viewing angle IPS display housed in a robust CNC aluminium alloy casing. With wired connectivity for remote monitoring via Android and detailed PC software for offline data logging, the FNB58 offers the build quality and software depth required by repair technicians and electronics enthusiasts.

Features

Comprehensive Protocol Analysis: Verify the true capabilities of your power bricks by actively triggering and monitoring modern fast-charge protocols, including PD3.0, QC3.0, VOOC, and SuperVOOC.
Lab-Grade Visualisation: Detect subtle power instabilities and noise using the built-in visualisation mode, which plots real-time waveform curves for voltage and current ripple on the 6-digit high-precision display.
Cable Quality Verification: Eliminate voltage drop issues in your projects by measuring the differential pressure and internal resistance of your USB cables to ensure they meet specifications.
Robust Construction: Designed to withstand the rigours of a busy workshop, featuring a durable aluminium alloy enclosure and a physical 'PD Switch' to safely disable power delivery communication when monitoring sensitive devices.
