Description
xProduct overview
The FNIRSI FNB58 USB Tester is a compact, multi port power meter designed to help you verify charging behavior across USB A, Micro B, and Type C connections. Its crisp 2.0 inch TFT LCD presents clear numbers in any lighting, making it easy to capture data on the go and compare charging scenarios side by side.
Designed for real world testing, the FNB58 pairs precision electronics with a practical app experience. A high resolution 16‑bit ADC and a dedicated PD protocol chip enable accurate readings and smooth data presentation. The device can monitor voltage, current, power, resistance, capacity, and D+/D- voltages, while also delivering ripple and waveform visuals that reveal power stability in a single glance.
What it measures and how it helps
Six digit display of voltage, current and power gives you precise numbers. Ten switchable capacity presets let you compare multiple tests quickly. The tester supports low‑speed to high‑speed waveform capture and ripple visualization, with sampling rates up to four million samples per second, enabling detailed power analysis.
- Six digit voltage, current and power readout
- Ten capacity presets for fast comparisons
- Waveform capture and ripple plotting up to 4 MSPS
- Onboard temperature reading and startup time recording
Fast charge protocol detection
Automatic monitoring covers a broad set of standards. It supports QC 2.0 and 3.0, FCP, SCP, AFC, PD 2.0 and 3.0, VOOC and WARP, plus Super VOOC triggers. When a protocol isn’t supported, the device can default to a safe 5 V output to continue basic measurement.
What you can test with it
Use the tester to explore charger and cable performance, observe how voltage and current behave under load, and compare devices for stability. Built‑in E‑Marker cable reading and DASH cable data reading add transparency to data, while the app enables convenient logging and analysis.
- Test chargers and cables for charging efficiency
- Verify wire and connector performance with resistance readings
- Log data over time to spot trends in power delivery
How to use and notes
In keeping with environmental goals, the manual is accessed via a QR code in the packaging. Activate the PD function switch, select the correct input port, and choose a compatible protocol. If a protocol is not supported, the tester may default to 5 V output.
