Simplified USB Tester for Type-C Fast Charge Detection

The FNIRSI-FNB58 Digital Voltmeter Ammeter USB Tester, also known as the QDTimes USB Tester, is a versatile device that offers a range of features for monitoring and analyzing USB-powered devices. This compact and portable tester boasts a 2.0-inch full-color ultra-wide viewing angle TFT LCD display, along with integrated USB-A, Micro-USB, and Type-C interfaces.

One of the standout features of the FNIRSI-FNB58 is its ability to provide real-time detection of subtle changes in voltage, current, and power during the recharging process. With a low resolution of 0.0001, this tester is capable of accurately monitoring and recording these parameters. It supports a wide range of automatic protocol detection, including PD2.0, PD3.0, QC2.0, QC3.0, QC4, SCP, AFC, PE, DASH VOOC, superVOOC, and more.

The device's four-function curve display allows users to view the real-time voltage and current curves, enabling them to identify any abnormalities in the recharging process immediately. Additionally, the offline curve recording feature supports up to 9 hours of voltage and current curve data, which can be reviewed during the recharging process. The D+/D- voltage curve can also be used to monitor changes in the recharging protocols and master the process in real-time.

For users who require more advanced features, the FNIRSI-FNB58 also offers a BT (Bluetooth) version, which allows synchronization of data to a mobile phone and provides an app-based overvoltage and overcurrent alarm function. This feature is exclusive to the BT version.

In terms of specifications, the FNIRSI-FNB58 can monitor voltage ranging from 4V to 28V with a resolution of 0.00001V and an accuracy of ±(0.2‰+2). The current monitoring range is 0 to 7A with a resolution of 0.00001A and an accuracy of ±(0.5‰+2). The power monitoring range is 0 to 120W with a resolution of 0.00001W and an accuracy of ±(0.5‰+2).

The device also supports load equivalent internal resistance measurement, with a range of 0 to 9999.9Ω and a resolution of 0.0001Ω and an accuracy of ±(0.5‰+2). The D+/D- voltage range is 0 to 3.3V with a resolution of 0.001V and an accuracy of ±(1.0%+2).

Additionally, the FNIRSI-FNB58 can measure capacity in the range of 0 to 9999.99Ah with a resolution of 0.00001Ah and energy used in the range of 0 to 9999.99Wh with a resolution of 0.00001Wh. The cable resistance measurement range is 0 to 9999.9Ω with a resolution of 0.0001Ω.

The compact size of the FNIRSI-FNB58, measuring 82 x 42 x 12mm (3.2 x 1.7 x 0.5 inches), makes it a convenient and portable tool for users who need to monitor and analyze USB-powered devices on the go.
