The USB Socket with a 10A current rating and a 250V rated voltage, such as the JXN-6 cassette, is designed to provide a reliable power source for charging devices. These sockets often come with multiple USB ports, allowing for the simultaneous charging of several devices. They are built with safety features like flame retardant materials and may include indicators for power status. The integration of USB ports in power sockets has become increasingly common in modern electrical installations, providing convenience and flexibility in both residential and commercial settings.
