Add Bluetooth Audio To Your Car
Enjoy wireless music and hands-free calling through your vehicle’s existing stereo with this Bluetooth 5.0 FM transmitter. It plugs directly into a compatible 12V or 24V vehicle power socket, making it suitable for many cars, SUVs, vans and trucks equipped with an FM radio.
Play Music Through The Vehicle Speakers
Connect a compatible smartphone through Bluetooth and transmit its audio over an available FM frequency. Tune the vehicle radio and transmitter to the same frequency between 87.5 and 108MHz to hear music, navigation audio and supported calls through the car speakers.
For the clearest sound, select an FM frequency that is not occupied by a local radio station.
Hands-Free Calling With Built-In Microphone
Use the integrated controls to answer or end compatible calls without holding your phone. The supplier lists a noise-reducing microphone designed to improve voice clarity during conversations.
Call quality can vary according to the mobile signal, vehicle noise, microphone position and FM interference.
Dual USB Charging
Two USB ports provide a supplier-listed combined output of up to 3.1A, allowing two compatible USB-powered devices to be charged simultaneously.
This product does not list USB Power Delivery, Qualcomm Quick Charge or another named rapid-charging protocol. Charging speed depends on the connected device, cable and shared output.
MP3 Playback From A USB Flash Drive
Prefer to play saved music without using your phone? Insert a compatible USB flash drive containing supported audio files and enjoy your personal playlist through the car stereo. The transmitter supports supplier-listed USB storage capacities up to 32GB.
The USB flash drive is not included.
Real-Time Vehicle Voltage Display
The digital display shows the vehicle’s supplied voltage while the transmitter is operating. This provides a convenient reference for monitoring unusual voltage changes, although it is not a replacement for professional battery or alternator testing.
Convenient Knob And Button Controls
The combined control knob and buttons provide accessible operation for adjusting volume, changing tracks and managing compatible phone calls. Set up the device before driving and avoid making adjustments that could distract you on the road.

Received. 👍 👍 👍
That seems correct to me, now we just need to try it out.

Works good and is extremely affordable. I wonder if they even make any profit lol. This is my backup transmitter, it sounds better than a $17 one on amazon! Not as good as a lencent or nulaxy, but for the price i can't complain! Very great and highly recommended, especially as a backup or for use for fleet vehicles.

Thank you. The package was sent quickly.

It works well, the volume is a bit low but you can just increase it from the phone and the device, then everything can be controlled from the radio, but if you increase the volume too much there is quite a loud background noise. The delivery has been very fast.

Honestly, in terms of quality and price, there's nothing better. It works perfectly, I recommend it.
