UGREEN FM Transmitter Bluetooth 5.0 car charger MP3 3x USB TF micro SD 4.8A (CD229) connects smartphones and other Bluetooth devices to a vehicle radio via FM transmission while providing charging for devices. It includes Bluetooth 5.0 for stable pairing, a large LED display, support for TF/microSD and USB flash drives with common audio formats, and three USB ports (two USB-A and one USB-C) for charging and playback. The unit is compatible with 12–24V vehicle power supplies and supports hands-free calls through a built-in microphone with noise suppression.

Advantages

The transmitter uses Bluetooth 5.0 for faster, more stable connections and improved audio transmission compared with older Bluetooth versions. A high-performance microphone with CVC noise suppression enables clearer hands-free calls. Two USB ports and one USB-C port provide simultaneous charging and playback: one PD-capable fast-charge port (USB-C) and a second USB port for reading music from a flash drive. The device stores the playback position when power is removed and features a clear LED display for frequency and track information.
