The FNIRSI FNB48P is an advanced USB port tester for accurate charging analysis. It supports multiple interfaces and fast charging protocols, operates at high currents, and allows for precise monitoring of voltage, current, and power. It offers smart cable diagnostics, data recording and analysis, clear graphs, and automatic screen orientation. The entire device is encased in a sturdy metal housing and powered by an efficient processor, making it a reliable tool for everyday use and advanced testing.

Unlimited versatility

The FNB48P supports multiple interfaces, including USB-A, USB-C, and Micro USB, making it suitable for both newer and older configurations. The tester operates with a high current of up to 6.5A and is compatible with a variety of input and output ports, such as USB-A I/O, USB-C I/O, Micro USB I/O, and a dedicated PD COM connector. This allows you to analyze virtually any charging scenario.

Full fast charging support

FNIRSI FNB48P recognizes and verifies the most popular fast charging protocols, including Apple 2.4A, QC2.0, QC3.0, USB Power Delivery, Samsung AFC, Huawei FCP and SCP, OPPO VOOC, DASH, WARP, SuperVOOC, as well as PE+ 1.1 and PE+ 2.0. The device detects the supported standard and checks its compatibility and correct operation, making it easier to evaluate the capabilities of the charging kit.

Advanced cable analysis

The tester allows you to detect PD e-marking cables by reading data from the CC line and information stored in the e-marking chip. It also supports the identification of DASH cables by reading data from their circuits. In addition, the internal cable resistance measurement function, performed in a fast, two-stage mode with a constant current load, allows you to accurately assess the quality of the cable and its influence on energy losses.

Laboratory-grade accuracy

A maximum resolution of 0.00001 allows the tester to monitor even the slightest changes in voltage, current and power in real time. The six-digit, high-precision display combined with a 240 MHz operating frequency and a powerful ARM MF processor allows the device to easily perform multi-program data processing.

Clear display and advanced visualization

A large 1.77-inch HD display provides a direct view of all key parameters. The tester offers four graphing modes, including voltage-current ratio, DD voltage, offline recording and power ripple using an AC connection. This solution allows you to customize the analysis according to your current needs.

Smart recording and calculation

FNIRSI FNB48P allows you to record up to ten groups of measurement data. Built-in battery capacity calculation algorithms allow you to quickly and conveniently determine the actual charging efficiency and effective capacity of the device under test without the need for external tools.

Automatic orientation and robust construction

The integrated gravity sensor supports automatic 180° rotation of the interface, and 360° in simple mode, so that the data readings remain legible regardless of the measurement position. The entire device is enclosed in a uniform, CNC-milled metal housing, which not only looks professional, but also effectively protects the electronics and emphasizes the rugged, “strongly armed” nature of the device.

PC-ready

The tester has a PC interface, a set of function buttons and a return key, which facilitate control directly from the device. This is a universal USB tester for demanding users, service providers and electronics enthusiasts who expect maximum accuracy and complete control at every stage of charging.
