Features:

• 【USB Cable Performance Testing】Test USB cable continuity, functionality (charging, data transfer, high-speed signal), and measure internal resistance for power efficiency. Verify ground wire connection to outer shell for cable integrity, safety, and shielding.
• 【Type-C eMarker Chip Reading】Reads eMarker chip parameters in Type-C cables, providing detailed performance information (e.g., maximum current, voltage, data transfer rates) to help users fully understand cable capabilities and ensure safe, efficient device usage.
• 【High-Definition Color Display】 The USB cable checker features a 2.4-inch high-definition color display. With the left white button, you can easily switch between function pages to view real-time detailed status of the cable, including internal resistance, power delivery efficiency, and cable quality. This helps you quickly identify inferior cables.
• 【Wide Compatibility】The usb tester can accurately identify and verify USB cable versions, including USB 2.0 and USB 3.2. It integrates PD 3.0 and PD 3.1 protocol detection functions, enabling quick verification of whether the cable supports the latest PD 3.0/3.1 standards, ensuring the cable meets high-power charging and fast data transfer requirements.
• 【Multiple Power Supply Options】The black button on the left can flexibly switch the power supply mode, and support the use of AAA battery or Type C 5V to stably supply power to the USB tester
