FM transmitter for car audio

This Adeco Auto accessory plugs into a 12 V socket and broadcasts audio to the car radio on frequencies between 87.5 and 108 MHz. It accepts wireless connections up to 15 m away and plays MP3 files from a USB stick inserted in the designated port. Dual USB outputs supply 5 V at 2 A total for charging two devices at once. The unit operates from 9 to 26 V and functions in temperatures from 0 to 50 °C.

Drivers who want wireless music and hands-free calls

Commuters with older stereos lacking auxiliary or Bluetooth inputs can stream audio and take calls through the built-in microphone effective from 0.5 to 2 m. Buyers who need higher charging currents, aptX or AAC codecs, or a display for track information should look at other solutions. The transmitter prioritises Bluetooth over USB or line-in sources when multiple inputs are active.

Stereo digital PLL locking on 87.5–108 MHz

The single specification that decides fit is the FM transmission method: stereo digital PLL locking across the full 87.5 to 108 MHz band. If the vehicle’s radio cannot tune this range or suffers strong local interference on these frequencies, the transmitter will not deliver clear audio.
