FNIRSI FNB58 USB Tester is a multi-functional tool designed to monitor and measure USB power parameters, with two available versions—one featuring Bluetooth for wireless data transmission and another without. Both versions provide real-time measurement of voltage, current, power, and more, making them invaluable tools for testing chargers, cables, power banks, and USB-powered devices. Below is a technical description for both versions:

1. Display:

  • Type: 0.96-inch IPS LCD color display with a wide viewing angle.
  • Resolution: High clarity for multiple parameters displayed simultaneously.
  • Interface: User-friendly layout with real-time data.

2. Measurement Capabilities:

  • Voltage: 4V to 30V (±0.01V accuracy).
  • Current: 0A to 5.1A (±0.001A accuracy).
  • Power: 0W to 150W.
  • Capacity: 0 to 99999mAh.
  • Energy: Measured in watt-hours (Wh).
  • Resistance: Calculates load resistance based on current and voltage.

3. USB Ports:

  • Input and Output Ports: USB Type-A and USB Type-C for wide compatibility.
  • USB Type-C (Bi-directional): Measures in both input and output directions.

4. Protocol Triggering:

  • Supports Power Delivery (PD), Quick Charge (QC 2.0/3.0), and other fast-charging protocols, making it versatile for various USB devices.

5. Bluetooth Version Features:

  • Wireless Data Transmission: The Bluetooth-enabled version allows real-time monitoring and data transfer to a smartphone or PC via a dedicated app. This feature is useful for logging and analyzing data over time, especially during long testing sessions.
  • App Functionality: The app enables remote viewing of voltage, current, and power usage, and stores logs for later analysis.

6. Data Logging & Memory:

  • Both versions feature data logging to monitor total power usage, capacity, and energy consumption.
  • Bluetooth Version: Offers wireless data logging and export, while the non-Bluetooth version only supports on-device display.

7. Accuracy & Sampling Rate:

  • High precision with fast sampling rates for real-time data display.

8. Safety Features:

  • Over-Voltage/Over-Current Protection.
  • Reverse Polarity Protection.

9. Physical Design:

  • Compact, portable form factor with robust plastic housing.
  • Bluetooth Version: Same physical dimensions but includes a Bluetooth module for wireless communication.

10. Additional Features:

  • Temperature Monitoring.
  • Backlight Control.
  • Port Identification.

11. Use Cases:

  • Charger and cable testing.
  • Power bank performance verification.
  • Battery diagnostics.

12. Package Contents:

  • 1 x FNIRSI FNB58 USB Tester (Bluetooth or Non-Bluetooth version).
  • 1 x User Manual.

The Bluetooth version provides added convenience for professionals and enthusiasts who need to monitor USB power metrics remotely, while the non-Bluetooth version offers the same precise measurements at a lower price point.
