FNIRSI FNB48P Black USB Port Tester

FNIRSI FNB48P Black USB Port Tester

The FNIRSI FNB48P is an advanced USB port tester designed for precise charging process analysis. It supports multiple fast charging interfaces and protocols, operates at high current, and enables accurate voltage, current, and power monitoring. It offers intelligent cable diagnostics, data recording and analysis, clear graphs, and automatic screen orientation. The entire unit is housed in a robust metal housing and powered by a powerful processor, making it a reliable tool for everyday use and advanced testing.

Versatility without limits

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 at a high current of up to 6.5A and works with a wide range of input and output ports, such as USB-A in/out, USB-C in/out, Micro USB in, and the dedicated PD COM port. 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, allowing you to more easily assess the capabilities of the charging kit.

Intelligent Cable Analysis

The tester enables the detection of PD e-marker cables, reading data from the CC line and information stored on the e-marker chip. DASH cable identification is also supported, along with data from their circuits. Additionally, the internal resistance measurement function, implemented in a fast, two-stage mode with a constant current load, allows for precise assessment of cable quality and its impact on energy loss.

Lab-Grade Precision

With a maximum resolution of 0.00001, the tester allows you to monitor even the smallest changes in voltage, current, and power in real time. The six-digit, highly precise reading, combined with an operating frequency of 240 MHz and a powerful ARM MF processor, allows the device to effortlessly handle multi-tasking data processing.

Clear screen and advanced visualization

The large 1.77-inch HD display provides instant insight into all key parameters. The tester offers four graphing modes, including voltage and current, DD-voltage, offline recording, and AC-coupled power ripple. This solution allows you to tailor your analysis to your current needs.

Intelligent Records and Calculations

The 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 being tested, without the need for external tools.

Automatic orientation and solid construction

The built-in gravity sensor supports automatic interface rotation by 180°, and in straight mode, also by 360°, ensuring the data remains legible regardless of the measurement position. The entire unit is housed in a seamless, CNC-milled metal housing that not only looks professional but also effectively protects the electronics and emphasizes the device's robust, "armed to the teeth" character.

Computer Ready

The tester is equipped with a PC interface, a set of function buttons, and a return key for easy operation directly from the device. This is a versatile USB tester for demanding users, service technicians, and electronics enthusiasts who expect maximum precision and full control over every charging stage.
