Product description
The FNIRSI FNB58 USB tester is a multifunctional tool for testing and monitoring USB power ports.
This tester makes it easy to determine the voltage, current and power supplied by the USB port under test.It is ideal for diagnosing and repairing USB ports on various devices, such as laptops, tablets, mobile phones and more.
The tester is equipped with a 1.77-inch high-resolution TFT graphic display. The display clearly shows numerical charging values, and can be easily switched to a graphical representation of changes in the charging status, with a display similar to that of an oscilloscope. For ease of use and reading, the display also features 360° rotation.
The tester is a versatile device and is equipped with standard ports, including USB-A, microUSB and USB-C. Its versatility is further enhanced by its ability to detect various fast-charging protocols, such as QC2.0/QC3.0, Huawei FCP/SCP, Samsung AFC, PD 2.0/3.0, VOOC/WARP and Super VOOC 1.0/2.0. It uses a specialised 16-bit ADC and a PD protocol chip for measurements.
