Nulaxy 54W Bluetooth 5.3 Car Adapter with 4 Charging Ports [PD 36W & QC3.0 18W], Wireless Radio FM Transmitter with Deep Bass Player & 5 Colors LED Backlit, Hands-Free Calling, BlackCarbonfree Certified

Initially I was just searching for a decent plug-in car charger with at least 2 Power Delivery USB-C and 2 USB-A ports. Then I stumbled upon this product in the same price range. It had most of the charging port specs I wanted AND there was the added function of turning my car radio into a bluetooth speaker. I was a bit suspicious of the quality of these features based on the low $10 price tag, but I figured “oh what the heck, as long as it charges my phone, any other features are all up-side, regardless or quality.”Well, it turns out after receiving and briefly testing out the item, all of the advertised features work well and I couldn’t come up with any complaints about the quality. I’m not an audiophile, so I can’t really tell you about all the different sound characteristics, but I can definitely say that the sound was clear with no static. The FM signal was strong to create complete silence on the radio station you tell it to connect to (when it is connected but no sound is playing). The microphone built into this device transmitted my voice clearly to the person on the other end of a phone call, without me having to pay special attention to where I was directing my voice from a normal driving position in my truck with my power port down low front and center. I even tried it in a power port located inside an open armrest console slightly below where the driver’s elbow would be, and it still picked up my voice clearly.It’s nice that it allows you to choose whatever FM frequency you want for transmitting to your radio. The bluetooth connected to my phone easily. The colorful LED light ring around the device lets you choose the color or let it continuously slowly cycle through all the colors, but I found the best LED feature to be the fact that you can turn them the lights off. I also like that you can easily hold a button down to turn the entire unit off when you don’t want it to automatically connect to your phone and vehicle. This is also good for preserving my truck’s battery since my power port is the type that stays on even when my truck is off. Note that the charging ports DO still work when the rest of the unit is powered off. The bass boost option toggles on and off, but my truck has crappy speakers, so I couldn’t tell if this feature improved the sound or made it worse. There’s even a voltmeter built in that lets you see the voltage of your vehicle’s battery whenever you power this unit on. That will help me monitor how much drain is on my truck’s battery after long periods without running it. I haven’t yet had a chance to properly test the accuracy of the advertised charging port specs, but I’ll update this review if I find that the charging speed or wattage don’t seem as advertised. I’ll also update this review if the quality of the product degrades or if it stops working too soon.If I were being greedy, the only improvements to this product that I would have asked for would be an increase in Power Delivery charging wattage specs. And although the following is probably overkill, I like the idea an additional mechanical switch to turn off power to the entire device including the charging ports, absolutely ensuring zero phantom drain on the car battery. Such a feature does not seem to be popular on chargers anywhere though since their phantom drain when not in use is considered negligible enough.Overall I find this product to be GREAT and as FLAWLESS as you can get for $10. I plan to order one in a different color for another vehicle as soon as I submit this review.

Great device. Sturdy and easy to use. Make sure you don’t have your phone volume on max maybe a notch or 2 below and adjust volume from radio for best sound. Make sure your gains on radio are set. I believe all poor reviews on this are from user error.

Easy to connect, easy to set up and use.Randomly will have more static than I would like but overall I can always find a new station. Colors are not very bright so it doesn’t affect driving at night.

Works great, use it on the work truck. only issue is it stays on and connected for about 10 or 20 minutes after shutting the car off. So it can hijack your phone if you are close to the vehicle

This thing works great! We were looking for a way to charge your phone, and play the music, and every combination we tried just didn’t work. This worked instantly. Somehow, it sounds better than the radio even. There was basically no set up required also. Highly recommended!

This is such a nice looking fm transmitter and works well. Even with some other radio signal coming in this still brings clear signal and connects ultra fast. Has multiple colors to match your stereo and can even charge your phone. You can twist the knob and change songs too.

Why did you pick this product vs others?:I picked this because the price. I am so glad I did. It works great and easy to use.

Setup was easy, sound typical FM quality. Low-end and mid-range fine, high-end frequencies missing a bit. Adjustable bass really made a difference. Great way to play your phone's music through your car system in older cars.
