Uni-T UT658A USB tester
The Uni-T UT658A is a USB tester designed to monitor the parameters of chargers, power banks, USB Type-A cables, and other power supply devices. The device measures voltage in the range of 4–24 V DC, current from 0.05 to 3 A DC, capacity up to 99,999 mAh, energy up to 1000 Wh, equivalent circuit resistance from 1 to 480 Ω, and D+ and D- data line voltages up to 3.3 V, allowing for a quick assessment of power quality and the condition of the tested equipment. The model supports USB Type-A ports, USB 2.0 and 3.0 standards, and QC 3.0 fast charging. Additionally, it allows for the storage of 10 data sets and the recording of measurements for up to 99 hours, 59 minutes, and 59 seconds with a resolution of 1 second. Simultaneous display of key parameters on the screen facilitates result analysis, while the compact dimensions of 93 × 45 × 13 mm and a weight of 50.6 g make the device convenient for everyday use and easy to carry.
