Transmission Interface: Standard USB 2.0 architecture. The connectors feature white or black internal alignment plastics (rather than the blue indicator tabs seen on newer USB 3.0 lines), maintaining backwards compatibility with legacy USB 1.1 setups.Data Transfer Rates: Supports data transmission speeds capping at 480Mbps. While fully sufficient for standard devices, it will constrain the speed of modern external USB 3.0 hard drives or fast flash drives.Power Pass-Through: Safely passes standard 5V USB bus power. Because 1.5 meters is a short run, there is negligible line resistance or voltage drop, making it efficient for charging basic electronics or driving unpowered accessories.Build Quality
