Bluetooth 5.4 FM Transmitter Car Adapter with 48W USB Charging

Signal Path Meets Power Output

This FM transmitter uses Bluetooth 5.4 wireless communication with stereo FM broadcasting through the vehicle radio system. The housing is constructed from molded plastic with a plug-in cigarette lighter format for standard 12V and 24V vehicle electrical systems. Dual charging outputs include a USB-C PD port rated at 36W and a USB-A port rated at 12W for simultaneous device charging. The front panel integrates an LED display, multifunction control buttons, and a selectable ambient light ring with manual on and off switching through the control interface.

From Device to Dashboard Audio

The adapter receives audio through Bluetooth and retransmits the signal over a selectable FM frequency for playback through the vehicle stereo. Integrated controls manage call routing, audio playback, bass adjustment, and frequency tuning directly from the unit body. The system supports USB flash drive audio playback up to 64GB using compatible audio file formats and operates through a two-channel stereo audio output configuration. Built-in noise suppression and echo reduction functions are integrated into the hands-free calling circuit during microphone use.

Plug-In Setup and Daily Handling

Installation requires insertion into a vehicle cigarette lighter socket. Initial pairing is completed through the Bluetooth menu of a compatible smartphone, after which the adapter reconnects automatically when vehicle power is restored. The LED display provides FM frequency and charging status visibility during operation, while onboard buttons control playback and communication functions. Exterior surfaces can be cleaned using a dry microfiber cloth, and the compact housing stores directly in the center console, dashboard compartment, or glove box when not connected.
