4-Port USB Car Charger with 48W Type-C PD Fast Charging

I have a Mercedes S Class with a built-in phone system that used to work great until Verizon shut down the older networks. Not wanting to overhaul the car's system, I found this device. I had a similar model in my Ford truck that worked great. The Mercedes doesn't have an audio jack, so using the radio system is the only option. The device fits nicely into the cigarette lighter socket and pairs quickly with my iPhone. The call quality is loud and clear, controlled via the steering wheel buttons. I made a small holder for my phone so it's easy to use. This is as good as it gets for making hands-free calls again.

You can change the frequency settings by pressing the call button. It is not in the manual. The higher the frequency, the worse the sound quality, and the lower the frequency, the better the sound quality. I don't know why, but I'm using it in a low-frequency band. The sound quality is not better than when connected with a 3.5mm cable. The difference between wired and wireless is inevitable. I had to raise it to 15 to 20 based on the car audio I used, so I could hear it while driving. In general, I listen to the radio at about 5-6. That sounds so small. The pairing speed is definitely fast. It doesn't take a second, it seems to take two to three seconds, but it doesn't bother you. It's a little uncomfortable because you can't always do the LEDs around the product. If you press the button on the left, it will turn off, but it is uncomfortable because you have to turn it off from time to time. Other than that, it's worth it.

I tuned it to a blank radio frequency as instructed and it connected easily to my phone. It’s much more flexible than other products with pre-set stations. I can’t use the Aux option in my car, but the included cable is a nice touch. The volume dial syncs with my phone, which is convenient. The bass button needs a couple of seconds to activate but it's pretty noticeable. The lighting is cool, especially for night drives, and the various charging ports are handy. I haven’t tried phone conversations yet, but I’m optimistic about it. It's nicely compact compared to other models, making a real difference compared to using a portable speaker.

The sound quality is crystal clear, as long as you find a static-free station. The bass boost isn't necessary for every song, but it's a nice feature to have when needed. The Bluetooth connection is super quick, and I was amazed at how fast it reconnected when I switched it between two 12V ports in my car. The mics are decent – I was told I sound a bit boxed in, but it's clear. Plus, since my car has an Aux port, I can connect it there for a static-free experience. It's packed with features like Quick Charge 3.0 and 40+W charging capability, which is impressive. The rainbow lighting is optional, and the display is very clear. Overall, for the price, this Bluetooth adapter is a steal.

It works really well and the audio quality is top-notch, super easy to use too. It also supports 25W Super Fast Charge on my Samsung phone with the USB-C port, which was a nice surprise. Just a heads up, if you hear weird whining noises that change with engine RPM, it's not the device's fault but electrical interference with the car's 12V system. Some cars have this issue. To fix it, you can power the device with a power bank that has a 12V outlet, or if you're into electronics, use two 9-volt batteries in series with alligator clips. This gadget can handle up to 24 volts perfectly. Just don't charge your phone with it when using the 9V batteries setup. This way, you can get rid of any interference noise and enjoy amazing audio quality.

This is an excellent gadget for the car. The car receiver picks up the frequency from the transmitter without any issues. Plus, you can change the frequency. It has all the essential buttons on the front panel. I wish it had options to change the bass level and equalizer settings. Also, it would be better if the buttons to change audio tracks were on the front, but those are available on bulkier models.

This is such a great product in so many ways. It's easy to use and once it's connected you will love it. What I really like about it doesn't have a long arm. It fits perfectly in my cigarette lighter and it's not in the way when I'm shifting the car. There is absolutely no static and the music sounds great, especially if you use the bass power button. You will not be disappointed with this product.

Been using it for a few days and it's awesome in my car! The sound quality is great and it's easy to get set up. I love that it remembers the station if unplugged and reconnects to play music when I get back in the car. It does start a new song rather than resuming the old one, but that's a minor issue. Highly recommend!

I got this to replace an older, bulkier model. It's good overall, with better sound quality and noticeable difference with the bass button. However, the colors aren't as advertised; it's more of a rainbow scheme, which isn't as pretty. It's a bit annoying that I have to adjust my phone's media volume each time I get in the car, but at least I can turn off the light.

I needed something to connect my old car to my phone for music, and this went above and beyond. My car is a 2005 Hummer, way before Bluetooth was standard. It connected effortlessly to my iPhone and I can now charge my phone and take calls at the same time. The volume syncs with my phone, so it's easy to control. It's perfect for older cars.

I love it, it works really well. I only had to connect it once and now it automatically connects every time I turn the car on!

This unit is fantastic! I only wish I could crank up the volume more, but maybe that's just my stereo system's limit. I'd recommend this to anyone, especially if you're not too tech-savvy.

It works just like a Bluetooth connection. Nobody even realizes it's part of the music system until they unplug it. The lights are just right and it's super easy to set up. Really happy with this purchase.

Finding the right station can be a bit tricky, but once you do, it works great with Bluetooth.

It's easy to use and works as intended. Great purchase!

It works well with no static. I use station 88.1, not the recommended one. It has two ports for chargers and just chimes when connected to your phone – no annoying voice.

After trying other units, I came back to buy this model again for a second car. It's incomparable in terms of sound quality, compactness, and functionality.

Works exactly as described.

Out of all the FM transmitters, this one is my favorite. It's a nice size, has super fast charging, and a bass boost feature I haven't used much yet.

It works perfectly and is super easy to connect to the car.

It works beautifully. Now I can connect my phone to my car via Bluetooth or the aux cord.

The transmitter was easy to use right out of the box, didn't even need the manual. Definitely something I'd recommend to friends and family.

When I tried tuning stations, it didn't sound great in my car, but using the aux plug makes it sound perfect.

Very good product, excellent Bluetooth connection. The new 5.3 version gives you very clear sound on both sides. The best car accessory I've ever had. It has multiple options like Bluetooth, aux, USB-C type fast charging connection, and it worked excellently. The two microphones provide the best call experience in a car.

Works very well. The audio quality is flawless and it's very easy to use. It also supports 25W Super Fast Charge on my Samsung phone with the USB-C port, which I wasn't expecting but is a welcome surprise.
