## Long description

The UNI-TI UT658DUAL is a compact USB-A and USB-C tester with dual displays that report voltage, current and power measurements in real time. Designed to connect between a power source and device, the tester provides simultaneous readouts for both ports so technicians and everyday users can verify charging parameters, detect irregularities and compare performance across chargers, cables and power banks. The unit supports pass-through charging and presents numerical values clearly on two independent screens for quick diagnostics.
Advantages
The dual-display layout allows monitoring of two ports or two parameters at once without switching modes. Built to measure voltage, current and power continuously, the tester helps identify unstable outputs, weak cables or faulty chargers. Its portable form factor and straightforward connection make it convenient for field testing and bench use. Clear numeric displays and simple controls reduce the chance of misinterpretation during fast checks.
Suitable for

How to use
