## Summary description

The Uni-T UT658LOAD is a professional USB tester designed to measure voltage, current, capacity, and energy of USB devices. It features an integrated load function for testing power supply stability and charging performance. Ideal for technicians and electronics enthusiasts, this device provides accurate diagnostics for USB ports, cables, and power banks, ensuring reliable operation of your electronic equipment.

## Long description

The Uni-T UT658LOAD is a professional USB tester engineered to evaluate the performance of chargers, power banks, USB Type-A cables, and various power supply devices. This versatile tool provides precise measurements of voltage, current, energy, capacity, and equivalent circuit resistance, while also monitoring D+ and D- data line voltages. By integrating a built-in electrical load, the device allows users to verify the stability and output capacity of power sources under real-world conditions, making it an essential instrument for electronics technicians and hobbyists alike.
Advantages
This USB tester offers significant benefits through its comprehensive measurement capabilities and integrated load functionality. The ability to simulate different current draws—specifically 0.5 A, 1 A, 2 A, and 3 A—enables users to stress-test power adapters and cables to ensure they meet their rated specifications. Its clear display provides a simultaneous view of critical parameters, which streamlines the diagnostic process. Furthermore, the inclusion of data memory for up to 10 sets of readings and support for the QC 3.0 fast charging protocol ensures that users can accurately track and log charging performance over extended periods.
Suitable for
Testing the output stability of USB power adapters and chargers
Verifying the capacity and health of power banks
Diagnosing faulty USB Type-A cables
Evaluating the performance of devices supporting QC 3.0 fast charging
Service and maintenance of electronic equipment
When it may not be suitable
This device is specifically designed for USB Type-A interfaces and is not compatible with USB Type-C or other connector standards without the use of external adapters. It is intended for low-voltage DC applications and should not be used with high-voltage power supplies or non-USB equipment.
Key specifications
Voltage measurement range: 4–24 V DC
Current measurement range: 0.05–3 A DC
Integrated load settings: 0.5 A, 1 A, 2 A, 3 A
Maximum power handling: 60 W
Capacity monitoring: up to 99,999 mAh
Energy monitoring: up to 1,000 Wh
Data storage: 10 sets of measurements
Supported protocols: USB 2.0, 3.0, and QC 3.0
How to use
To use the Uni-T UT658LOAD, connect the tester directly to your USB power source or insert it between the power source and the device being charged. Once connected, the display will automatically show the real-time voltage and current. To utilize the load function, select the desired current setting using the integrated controls to simulate a specific power draw. The device will then display the resulting performance metrics, allowing you to observe how the power supply maintains voltage under load. Data can be saved into the internal memory for later review.
What to consider before purchase
Ensure your equipment uses USB Type-A ports for direct compatibility
Verify that your testing requirements fall within the 4–24 V and 0.05–3 A range
Confirm if you require the integrated load function for your specific diagnostic tasks
Usage recommendations
Always ensure that the total power draw does not exceed the 60 W limit to prevent damage to the tester. When testing cables, ensure the connections are secure to obtain accurate resistance and voltage drop readings.
