A practical second‑generation USB tester for both USB-A and USB-C that measures voltage, current, power, capacity, energy consumption, and circuit resistance. It supports fast charging QC 3.0/4.0, features a clear display, memory for up to 10 data sets, and works without batteries – powered directly from USB.
The UNI-T UT658DUAL tester provides a complete overview of charging parameters for modern devices. On a single display you can monitor U/I/P, capacity (mAh), energy (Wh), and circuit resistance (Ω). Thanks to its wide 4–24 V DC range and current up to 3 A (USB-A) / 5 A (USB-C), you can easily test chargers, cables, and power banks.
The device automatically detects fast-charging protocols QC 3.0 (USB-A) and QC 4.0 (USB-C). It enables long-term tests with a timer up to 99:59:59 and stores 10 measurement sets for easy comparison. Its compact body (93 × 55 × 13 mm) and weight of 65.8 g make it an ideal tool for workshops, service centers, and home use.
