The Baseus S-16 is a versatile car accessory that combines a charger, wireless MP3 player, and FM modulator into one compact black unit. It plugs into 12V or 24V sockets and uses a coiled spring cable to connect the power plug to an ergonomic control panel, which features a digital display for monitoring FM frequencies and buttons for managing calls and music. You can stream audio via Bluetooth v5.0 or play files directly from a TF/Micro SD card through the integrated slot. To keep your devices powered, it provides two USB Type-A ports with a total output of 5V/3.1A, allowing you to charge smartphones or tablets while driving. The device is built from heat-resistant materials and includes built-in protections against overvoltage, overcurrent, and overcharging to ensure your electronics remain safe during use.
