UNI-T USB tester UT658A

The UNI-T UT658A is a compact USB tester designed to monitor the parameters of chargers, power banks, USB Type-A cables and other power supplies. The device measures voltage, current, energy, capacity, equivalent circuit resistance and the voltage of the D+ and D- lines, allowing you to quickly assess the quality and condition of the tested power source.

The UT658A supports USB Type-A ports and the 2.0 and 3.0 protocols, offering voltage measurement from 4 to 24 V DC and current measurement from 0.05 to 3 A DC. It also records capacities up to 99,999 mAh, energy up to 1,000 Wh, resistance from 1 to 480 Ω and D+/D- voltages up to 3.3 V. Support for the QC 3.0 protocol makes it useful when working with fast-charging devices.

Up to 10 data sets can be saved, with a maximum recording time of 99 hours, 59 minutes and 59 seconds at 1-second resolution. The key parameters are shown on the screen at the same time. Weighing just 51 g, the tester is convenient for servicing and testing on the go.
