The FNIRSI FNB58 USB tester is a multifunctional tool for testing and monitoring USB power ports. With this tester, you can easily determine the voltage, current and power that the measured USB port supplies. 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" TFT graphic display with high resolution. The display can easily read numerical charging values, the display can be easily switched for a graphical representation of changes in the charging status, when the display is similar to that on an oscilloscope. For easy use and reading of the display, it is also equipped with 360° rotation.
The tester is a universal device and is equipped with standard ports, including USB-A, microUSB and USB-C.
Its versatility is also enhanced by the detection of various fast charging protocols, such as QC2.0/QC3.0, Huawei FCP/SCP, Samsung AFC, PD2.0/3.0, VOOC/WARP and Super VOOC 1.0/2.0.. It uses a specialized 16-bit ADC and a chip with the PD protocol for measurement.
