Uni-T UT658LOAD is a practical USB tester for quick checking of chargers, power banks, and USB cables. It measures voltage, current, capacity, energy, equivalent resistance, and also voltage on the D+ and D- lines. Thanks to the built-in electronic load up to 60 W, you can easily test a power source’s behavior under real load.
The Uni-T UT658LOAD USB tester is designed for service, manufacturing, and hobby use wherever you need to verify the performance of USB power supplies and the quality of cables. It supports USB Type-A ports and USB 2.0 / 3.0 protocols, and its clear display shows key values simultaneously.
Its main advantage is the integrated load, which makes it easy to simulate current draw and observe voltage drop or source stability. QC 3.0 fast charging is also supported, as well as saving measured values for later evaluation.
Main advantages:
- Built-in load 0.5 A / 1 A / 2 A / 3 A (max. 60 W)
- Voltage measurement 4–24 V and current measurement 0.05–3 A
- Capacity measurement up to 99,999 mAh and energy up to 1,000 Wh
- Display of D+ and D- data-line voltage for more accurate diagnostics
- Memory for 10 data sets and logging up to 99 h 59 min 59 s
