Most car FM transmitters offer Bluetooth plus wired options such as USB‑A, USB‑C and a 3.5mm AUX input. Many models also broadcast on an FM frequency so you can pair them with your car stereo.

Listings commonly show Bluetooth 5.0 and Bluetooth 5.3. At least one product specifies a wireless streaming range of about 26 ft.

Many transmitters include dual charging ports and fast‑charge support. Common configurations show USB‑A ports around 12W (≈2.4A) and USB‑C Power Delivery ports from about 18W up to ~20W; some models also support Qualcomm Quick Charge.

Many include a built‑in microphone with noise‑suppression, a multi‑function button to answer and end calls, and automatic switching from music to hands‑free mode when a call comes in.

They use the standard FM band—typically 87.5 MHz to 108.0 MHz—and include frequency tuners or digital displays so you can match an unused frequency on your car radio.

Some models add bass and treble adjustment, a remote control, LED mood lighting, and other audio‑customization features.
