Uni-T UT658A USB Tester

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 supply devices. The device measures voltage, current, energy, capacitance, equivalent circuit resistance, and D+ and D- line voltages, allowing you to quickly assess the power quality and condition of the tested accessory. It is a practical tool for service, engineering, and everyday equipment testing.

Key measurements in a handy form

The UT658A model supports USB Type-A ports and 2.0 and 3.0 protocols, offering voltage measurement in the range of 4–24 V DC and current from 0.05 to 3 A DC. The device also allows monitoring of capacitance up to 99,999 mAh, energy up to 1,000 Wh, equivalent circuit resistance from 1 to 480 Ω, and D+ and D- voltages up to 3.3 V. Support for the QC 3.0 protocol enhances the tester’s utility when working with fast-charging devices.

Convenient data logging and compact design

The UT658A allows you to save up to 10 data sets, with a maximum recording time of 99 h 59 min 59 s at a resolution of 1 s.
