FNIRSI FNB58 USB Port Tester Black
The FNIRSI FNB58 is an advanced USB port and fast charging technology tester that allows you to easily check power parameters, protocol compatibility, and accessory quality. It offers a clear display, very high measurement precision, and broad support for fast charging standards from popular brands. It allows you to analyze voltage, current, power, and charging waveforms in real time and offline. It checks the quality of chargers, cables, and their actual performance, detecting weak or dangerous power sources. With Bluetooth connectivity and app support, it provides convenient data monitoring and additional safety features.
Enter the era of super-fast charging
The FNIRSI FNB58 is an advanced measuring tool designed for technology enthusiasts, service technicians, and anyone who wants complete control over the charging process. Support for PD3.1 standards with EPR AVS mode up to 28 V and detection of PD cables with power up to 240 W make the device a perfect fit for advanced chargers and accessories. It is a device that allows you to understand and fully utilize the potential of fast charging.
Precision that is visible at first glance
The front of the tester features a 2-inch high-resolution LCD display that presents complete and extremely accurate measurement data. A resolution of up to 0.0001 allows you to detect even subtle changes in voltage, current, and power in real time, so that any anomalies during charging are immediately noticeable. The simple, easy-to-read interface and independent function menu make operation intuitive and comfortable.
Robust design and full connector functionality
The FNIRSI FNB58 is equipped with a 5P high current capacity USB-A output and input, as well as Type-C and Micro inputs and a Type-C output. The use of 24-pin high-quality copper contacts in the Type-C port translates into stable and reliable measurements. The housing also features function buttons, a back button, a PC interface, and a dedicated PD switch, making the device a complete diagnostic center for USB ports and cables.
Full compatibility with the most popular standards
The tester supports a wide range of fast charging protocols, including PD 2.0 and 3.0, PPS, QC 2.0 and 3.0, FCP, SCP, AFC, PE, DASHVOOC, and SuperVOOC. This allows it to work seamlessly with Huawei, Xiaomi, and OPPO super fast charge technologies, as well as Apple Power Delivery and Samsung fast charging. Automatic protocol detection allows you to instantly check which mode your charger and cable are operating in.
Detect problems before they damage your equipment
Advanced power ripple measurement allows you to quickly assess the quality of the charger. The device clearly indicates the wave level, allowing you to assess whether the power supply is excellent, normal, burdened with high ripple, or even of poor quality. This helps you avoid using poor-quality chargers that shorten battery life and negatively impact device safety.
Real-time and offline curve analysis
The FNIRSI FNB58 displays live voltage and current waveforms, allowing you to immediately detect incorrect charging. In addition, it offers offline curve recording for up to 9 hours, allowing you to analyze the entire process after charging is complete. Monitoring D+ and D- curves gives you full insight into real-time charging protocol changes, making the tester an expert tool.
Cable and real-world performance diagnostics
The device can read data from the CC line in PD cables with an E-Marker chip, detect DASH cable parameters, and measure their internal resistance using a two-step method under a constant current load. This makes it easy to check whether the cable actually meets the declared parameters and is suitable for fast, high-power charging.
Intelligent power management
The tester supports the recording of up to 10 sets of charging and discharging power data, and the built-in algorithm allows for quick calculation of battery capacity based on the recorded values. Computer support without installing drivers ensures convenient data synchronization.
