Bluetooth 5.3 FM Transmitter Car Adapter - SONRU Car Charger 54W [PD 36W & QC3.0 18W], Wireless FM Radio Transmitter [HiFi Treble & Bass Player], 5 Colors LED Backlit, Hands-Free Calling, U-Disk

I received this device free to review for Sonru as a frequent customer. I still wanted to do an honest review so I used the device for a month to get a better picture of the build quality.Charger options: I used the device to charge an iPad, an iPhone, and an Android phone. Rapid charging was available thru 3 of the 4 ports. (The blue colored USB-A port is meant to have a thumb drive inserted to play music. It still charges, just not rapidly). When my wife and I were together we had two phones and iPad plugged in and all worked fine, but usually it was just 1 or 2 devices. The device charges as fast as plugged into the wall. 5-stars for the charging features!Hands-free device: Plug the device into the power (lighter) outlet, and press the button on the face. Open your phone's Bluetooth settings and pair to the device. You conmected your phone to the device.Now to connect the device to your vehicle. Find an FM frequency on your radio that is not being used commercially. Again press and hold the button until the FM radio frequency flashes. Turn the button to match the frequency on your FM radio. NOW, what happens on your phone will be transmitted thru your radio speakers! There is a Bass button on the side, which helps with the music playing. The other side button changes the light colors, and turns it off should you not want them on. Remember you can turn up the transmitted volume with the button on the front during a call or while the phone is playing. Need more volume still. Turn up the dial on your radio for even more. It plays very loud for me! The microphone on the device picks up just fine for most calls.If you play a youtube video, the sound comes out of your radio speakers. There is a lag time of about 1/2 second, if you are watching (not for the driver), but for podcasts, and music it is unnoticed.Sound quality during calls were extremely good within cellular limits. The improved Bluetooth connectivity really helps. I also know that sometimes changing the FM frequency can help also. When cellular signal was strong, so was the sound. The built-in microphone sounds as good as the built in microphone on our Hondas' hands-free links.As a hands-free device: 5-stars, after set-up.The instructions given in the owners manual are clear, but there are videos just above the reviews which easily show how to connect and use.OVERALL: A great device and a bargain. The charging features alone are worth the price, but the hands-free options seal the deal. So far the device has held up well, in colder weather. Thinking of more devices for our other car and as gifts for our kids!Highly recommended!

This auto bluetooth device is literally Amazing!!!! It has been an Absolute gamechanger for my car audio situation! As long as you pair it with a non-staticky radio frequency, you won’t experience Any static during your bluetooth experience! (If you get static, just try re-pairing it with a different frequency/station.) Also, if the bluetooth function is already on on your phone when you turn the vehicle on, the bluetooth device will Automatically and Immediately pair with your phone, making your listening experience So seamless and effortless!!I’ve tried these sorts of devices years ago, with a former car, and wasn’t at all looking forward to using one again presently, as the audio transmission so oftentimes was Sooo full of static! But that’s not the case, in the slightest, this go-round with This device! I could not be happier with its performance! And the experience is practically the exact same as if my car already came with bluetooth functionality! Plus, the various charging ports all seem to charge great too, without creating Any static interference with the audio quality/clarity.

Other reviewers have had sound quality issues, or have had to try several frequencies. I have not had those issues, but the sound is mono rather than stereo. Music quality will be degraded by transforming from digital to analog, compressing to mono, being broadcast and received, and then transformed back into a digital signal for your car's surround sound speakers. Voices and other types of content are fine and music is what it is.The other thing to note is that this is a fairly large unit. Make sure your outlet has enough clearance.

This transmitter fits perfectly in my truck. It was very easy to pair with my device and reconnects perfectly every time. I prefer not to use colored lights on the transmitter (too distracting for me at night) but this one lets you turn it off and it remembers next time it's used to stay off. I attached a photo without the light and one with red. There is a good variety of colors to pick from.As my truck came with a Bose radio system I don't need the bass boost feature, but it does increase low end sounds.Hands-free phone usage is good, both to hear caller and they can hear me.And as I travel with more than one device these days I like the variety of ways and ports to be able to plug into. My favorite is PD fast charging - easily keeps up while I navigate and stream music while traveling.

This is a very versatile multifunctional device. Besides the USB charger port, there is a U-disk playback port that can be used with a 64GB USB memory stick of music. The voltage readout is handy to alert you of your battery voltage level if you are listening to the music with the engine switched off (at a picnic or so). The PD ports (which require the appropriate cable) can be used to 5,9 and 12V output. The unit has a relatively high-power capacity compared to others I have tested. The Bluetooth function works flawlessly. The bass boost adds low end to the music playback. As with other adapters, the unit can select a suitable FM frequency for playback. I used the unit a a recent 2500 mile road trip and have no problem recommending it for those who need the BT capability or USB musing playback while you charge your other devices.

Pros:Easy setup, audio quality is good . Build quality seems solid. I was able to charge two phones, power a Dashcam and a LED Uber sign at the same time.Cons:FM Transmitter does not transmit a stereo signal, so music is in monoPower and charging to items is not consistentStarted hearing static after 30 minutes, especially on phone calls, this is after verifying that I was on a open FM frequencyMixed reaction from audio quality on the built in mics during phone calls, some said I sounded good, others said I sounded muffled and far away
