Uni-T UT658LOAD USB Tester
The Uni-T UT658LOAD is a USB tester designed to test 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 in the range of 0–3.3 V, allowing for a thorough analysis of the operating parameters of the tested equipment. An additional advantage is the built-in electronic load of 0.5 A, 1 A, 2 A, and 3 A with a maximum power of 60 W, which enables testing of power supplies and chargers under load. The model supports USB Type-A ports, USB 2.0 and 3.0 standards, and QC 3.0 fast charging, while the easy-to-read display allows you to monitor key parameters simultaneously. The device also offers memory for 10 data sets and a measurement logging function for up to 99 h 59 min 59 s, which enhances its usefulness during diagnostics and service testing.
