The FNIRSI FNAC-28 USB tester is a precise and specialized measurement tool designed for analyzing and troubleshooting USB port-based charging systems. This device goes beyond a simple voltmeter and ammeter by offering a set of advanced features, turning it into a small laboratory for testing chargers, cables, power banks, and other USB devices.
One of the standout features of the FNAC-28 is its high accuracy, provided by a 16-bit external analog-to-digital converter (ADC). This feature enables precise measurement of voltage (4 to 24 volts) and current (0 to 6.5 amps) with minimal error. The bidirectional measurement capability allows users to accurately monitor both the input power to a device (such as a power bank charging) and the output power from it (such as a power bank discharging).
In addition to real-time data display, this tester can plot voltage and current curves over time, which is very effective for detecting fluctuations and stability in charger performance. It also allows storage of up to 5 groups of measured data for later comparison and analysis.
In today's world, charging speed is a critical factor. The FNIRSI FNAC-28 tester acts as a trigger tool and can automatically or manually identify and activate various fast charging protocols. It supports common protocols such as QC2.0 and QC3.0, as well as brand-specific protocols like FCP/SCP (Huawei), AFC (Samsung), and VOOC/WARP/SVOOC (Oppo, OnePlus, Realme). This capability allows technicians and professional users to verify charger performance and compatibility with different devices.
The charging cable is a key component in the fast charging process, and a low-quality cable can significantly reduce charging speed. The FNAC-28 calculates the internal resistance of the cable using the differential pressure measurement method. Lower resistance indicates higher cable quality and its ability to transmit high currents with minimal voltage drop. This feature helps users distinguish original, high-quality cables from counterfeit or worn-out ones.
Considering the extensive features offered by the FNIRSI FNAC-28, including high measurement accuracy, support for multiple protocols, and advanced analytical tools, this product offers high value for specialist users. Its price is very affordable compared to professional laboratory tools, providing similar capabilities in a portable, pocket-sized package.

این تستر قادر به اندازهگیری ولتاژ در محدوده 4 تا 24 ولت و جریان در محدوده 0 تا 6.5 آمپر است.
بر اساس مشخصات فنی ارائهشده توسط سازنده، این دستگاه از پروتکلهای QC, FCP, SCP, AFC, VOOC و SVOOC پشتیبانی میکند و در لیست مشخصات، اشاره مستقیمی به پروتکل PD نشده است.
خیر، این دستگاه برق مورد نیاز خود را مستقیماً از طریق پورت USB که به آن متصل میشود تأمین میکند (Plug and Play) و نیازی به منبع تغذیه خارجی ندارد.
مهمترین مزایای آن شامل دقت بسیار بالاتر به دلیل استفاده از ADC خارجی 16 بیتی، پشتیبانی از طیف گستردهای از پروتکلهای فست شارژ اختصاصی (مانند VOOC/SVOOC) و قابلیتهای تحلیلی پیشرفته مانند تست مقاومت داخلی کابل و نمایش گرافیکی منحنی ولتاژ و جریان است که در مدلهای ارزانقیمت یافت نمیشود.
در مشخصات دستگاه به قابلیت ذخیرهسازی 5 مجموعه داده بر روی حافظه داخلی و نمایش منحنی روی صفحه خود دستگاه اشاره شده است. اما قابلیتی برای اتصال مستقیم به کامپیوتر و انتقال دادهها ذکر نشده است. با این حال، دستگاه از ارتقاء فریمور (Firmware) پشتیبانی میکند که معمولاً از طریق اتصال به کامپیوتر انجام میشود.
