PortronicsAuto One Smart Car Charger & Music Streamer with Hands Free Calling, Bluetooth 5.0, Quick Charge 3.0, 23W max Output, 360° Gyro Body, Dual USB Charging Slots(Black)

Very good product, It creates a whole new experience of my old car. It has multiple functionality which are very handy and useful.

4 in 1 connectivity product (USB, Aux, Memory card, Bluetooth). Nice bass and sound quality. Also quality of the product is great. In addition we can charge our mobile also. Fast Software & Hardware response. Recommended to people who love music's but don't have these connectivity features in the car music player.

Although the device works as intended, my main issue is that the FM transmitter (stereo) is always ON, even when you connect a line out cable to your car stereo. So your audio is always broadcasted, except when you make your call private (as per the manual)Secondly, the display quality is very poor and of low resolution TN type, I bought this especially for the music spectrum function but it turned out to be a fake display with no relevance to the music content. The product picture is a simulated high resolution type but it's actually the usual cheap Chinese type similar to the type you find in fake Chinese feature phones. This is my main disappointment.USB-SD card playback is not tested yet by me.Bass/treble work fine so does FM stereo transmission.

This car accessory is a great addition for older vehicles, offering easy Bluetooth media control. Installation was simple, and it's handy for hands-free calls and music streaming. However, the sound quality could be better, lacking depth and clarity. Overall, it's a recommended upgrade, but don't expect top-notch audio.

Design is good , Bluetooth works very well for mobile connects and songsCannot use for mobile call pickups.
