FNIRSI FNAC-28 USB-C/USB-A USB tester

FNIRSI FNAC-28 USB-C USB-A 2in1 USB tester

The FNIRSI FNAC-28 is a versatile USB-A and USB-C connector tester that combines voltage, current, and power measurement, along with fast charging support, in a single, compact device. It's designed for testing chargers, cables, power banks, and other USB-powered devices. With two measurement inputs, the tester allows for simultaneous monitoring of charging parameters for various types of cables and devices, increasing its versatility. The color OLED screen displays all key data: input voltage, current, and current power. These readings are visible in real time and easily accessible thanks to the intuitive menu and function buttons on the housing.

Precise measurement and heavy load handling

The built-in 16-bit analog-to-digital converter (ADC) ensures high measurement accuracy, which is particularly important for laboratory and service testing. The tester supports current loads up to 6.5 A, and the USB-C port enables bidirectional power flow. This allows you not only to measure power parameters but also analyze the quality of power transfer in both directions, which is crucial when testing devices with the Power Delivery function.

Automatic identification of fast charging protocols

The FNAC-28 automatically recognizes the most important fast charging protocols, including QC 2.0, QC 3.0, AFC, SCP, FCP, Apple 2.4A, VOOC, SVOOC, and PE. After connecting the charger or device, the tester displays a list of supported standards, voltages, and currents. You can also activate charging simulations, allowing you to check the charger's compliance with a given standard and its actual performance.

Extensive measurement functions

With its cable testing function, the FNAC-28 can not only detect damage but also measure cable resistance and assess its current-carrying capacity. The tester also allows you to simulate device load, allowing you to verify that the cable is functioning properly under real-world load conditions. The device can perform a battery capacity test, recording time, current, and power consumption. The FNAC-28 records up to five sets of measurement data, which are automatically stored in the device. This allows you to easily assess battery wear or test new cells before installing them in devices.

Advanced Settings Features

The FNAC-28 allows you to adjust the display brightness, set the standby time, and select the temperature unit (°C/°F). Additionally, the device supports switching the interface language between English and Chinese. The tester can also simulate standard charging profiles, such as Apple 2.4A or DASH, allowing for comprehensive power supply testing without the need for additional devices. Furthermore, the tester can display data as graphs in three modes: classic – with real-time voltage and current, D+/D- line voltage data analysis mode, and voltage interference analysis mode, which detects power supply instability.
