The UNI-T UT658DUAL is a second generation USB tester that allows comprehensive analysis of chargers, cables and devices powered by USB Type A and Type C ports. With its help, you can not only check the voltage and current parameters, but also measure the actual energy consumption, the capacity of the charged devices and the resistance of the circuit. It is an indispensable tool for engineers, electronics engineers, device testers and home users who want to have full control over the quality and performance of their devices.
The UT658DUAL displays all the key information on an easy-to-read screen: voltage, current, power, capacitance, power consumption and circuit resistance values. It supports a voltage between 4 and 24 V DC and a current of up to 3 A in the case of the USB-A port and 5 A in the case of USB-C, so it is also suitable for testing the most demanding chargers and power banks. The device also recognizes QC 3.0 (for USB-A) and QC 4.0 (for USB-C) fast charging protocols, making it a universal tester for modern mobile devices.
The tester can store up to 10 data lines, so the measurement results can be easily compared under different conditions and with different devices. The battery capacity can be measured with a resolution of 1 mAh (up to 99999 mAh), and the energy can be recorded up to 1000 Wh. The maximum recording time is up to 99 hours 59 minutes 59 seconds - ideal for long-term load and comparison tests.
The UT658DUAL can be powered directly from the USB port and does not require additional batteries. Due to its compact size and light weight (65.8 g), it is extremely portable and easy to transport. Thanks to its single-screen display system and intuitive handling, it works just as well in laboratory conditions as it does during service or home tests.
