Bluetooth 5.4 FM Transmitter for Car

The Syncwire SW-XC653 plugs into a 12V-24V socket to add wireless audio streaming and hands-free calling to vehicles without built-in Bluetooth. It pairs with phones, tablets and MP3 players while dual USB ports charge two devices at once. A rotating knob controls volume and frequency selection.

38W PD & QC 3.0 Charging Upgrade

Replaces older transmitters limited to 5W or single-port charging by delivering up to 38W total through a 20W Type-C PD 3.0 port and a QC 3.0 port. The jump is worth it when you need fast charging for modern phones and tablets during the same trip.

Simple Plug-and-Play Install

Insert the adapter, tune the car radio to an unused FM frequency, match the transmitter to that frequency and pair via Bluetooth 5.4. Static interference usually means the chosen frequency is crowded; switch to another clear channel and repeat the pairing steps.
