USB Cable and Charger Tester with 1.44" TFT LCD Color Screen

This Mini Portable Multi-function USB Color Screen Tester hosts an impressive array of features designed to streamline device testing and debugging tasks. Equipped with a vibrant 1.44” TFT LCD display, it provides real-time visual representations of voltage, current, power, and more. Its ability to quickly identify fast charging protocols and switch between Chinese and English languages adds to its versatility for different scenarios.

The tester integrates seamlessly with various interfaces such as USB-A, Micro-USB, and Type-C, ensuring compatibility with most devices. Its capacity to measure the power output of USB interface devices makes it an indispensable tool in evaluating phone charging performance or emulating a DC regulated power supply using a protocol adapter. With protocols like PD being actively triggered, it caters to a wide range of debugging requirements.

However, safety precautions are paramount. Avoid connecting power supplies exceeding 24V, and note that only the USB-A input supports high-power input while maintaining vigilance with high voltage and power operations due to potential temperature increases. Additionally, remember that the HID-USB interface is strictly for data transmission and all interfaces connect in parallel, allowing only one input and one output simultaneously.
