FM transmitters for cars combine audio transmission with phone connectivity and, on supported models, device charging.

Brands include XO, Baseus, Maxlife, Blavec and Dudao, alongside Extra Digital, Setty and Forever. Available features include USB ports, USB-C connections, hands-free calling and LCD displays.
How to choose an FM transmitter for your car
Start with your main use: streaming music from a phone, playing MP3 files or charging devices during a journey. Check the selected model's power requirements, phone compatibility and connection options. For multiple devices, compare the number of ports and the output stated for each port rather than relying only on the overall charging figure. An FM transmitter and the car radio need to use the same FM frequency.
- Bluetooth connection: Options include Bluetooth 5.0 and Bluetooth 5.3 transmitters. Bluetooth provides the wireless connection between a phone and the FM transmitter for audio playback.
- USB and USB-C ports: Some transmitters offer two USB ports, while others include USB-C. Check which connections support charging and which support playback from a USB drive.
- Charging output: Selected models specify PD charging at 25 W or 30 W. The phone and cable also need to support the relevant charging mode.
- MP3 playback: Transmitters with MP3 and USB support provide an option for playing music files from a USB drive. This is useful when a stored playlist is your preferred audio source.
- Calling and display: Hands-free calling and an LCD display are available on selected transmitters. Compare button placement when choosing a device for regular calls.
For everyday commuting, Bluetooth playback and phone charging may cover the main needs. Multiple ports matter when travelling with several devices, while USB MP3 playback offers an additional music source for longer journeys.
Frequently Asked Questions
How does a Bluetooth FM transmitter work with a car radio?
A Bluetooth FM transmitter receives audio from a phone and broadcasts it on an FM frequency. The FM transmitter and car radio must be set to the same frequency.
Can an FM transmitter charge a phone at the same time?
FM transmitters with integrated car chargers can charge a phone through USB or USB-C. Charging output and support for PD vary between devices.
Do all FM transmitters support USB music playback?
USB music playback is offered on FM transmitters that specify MP3 and USB playback support. A USB charging port alone does not establish support for playing music files.
