UNI-T UT658DUAL USB Tester

is an advanced dual-interface measuring tool designed to evaluate the performance of USB charging adapters, power banks, USB-powered devices, and charging cables. Unlike traditional single-port testers, the UNI-T UT658DUAL USB Tester supports both USB-A and USB-C connections, making it compatible with modern smartphones, tablets, laptops, and fast-charging accessories.

This tester measures voltage, current, charging capacity, energy consumption, and charging time, allowing users to determine the actual performance and efficiency of chargers and cables. Its vivid LCD screen displays data clearly, enabling professionals and hobbyists to monitor charging behavior in real-time and detect abnormalities such as unstable voltage, weak current output, or cable performance loss.

With built-in protection features, the UT658DUAL prevents damage to connected devices by detecting abnormal voltage or current fluctuations. The compact and lightweight design makes it ideal for on-the-go testing, repair technicians, and electronics enthusiasts.
