Nulaxy 54W Bluetooth 5.3 Car Adapter 4 Charging Ports [PD 36W & QC3.0 18W], Wireless Radio FM Transmitter Hands-Free Calling Audio Receiver with Deep Bass MP3 Music Player & 5 Colors LED Backlit

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.

Works perfect for my 07 Hummer. Very easy to set up. Great for the price.

I purchased this very stationary bluetooth adapter after I got tired of my old one with a flexible arm constantly getting bumped out of place and losing its connection. This one works beautifully because nothing is bobbing around when I go over a bump.Another reason I purchased this adapter is because my old adapter would rarely connect to my phone without me going through all the steps manually. I'm not sure if that was an issue with my phone or with the adapter, but so far this new one has connected without issue every time.The USB port is working well.A few things I found that I'd say are negatives...1. If your cigarette lighter is way down near the floor, you're going to have a heck of a time trying to get this thing setup because you won't be able to see a darn thing. This was the case for me, clearly, and it was a bit cumbersome. The display points straight out and ONLY straight out, and my console is right there, so that was challenging. Now that it's finally setup, it should be okay as long as I stay in the city and don't need to adjust the radio dial. Hopefully.2. The single main button is a little challenging to use (particularly when you can't see it well.) One button controls three different functions and I find that to be much harder to use (especially while driving) than my previous adapter which had separate buttons for volume, radio dial, etc. The directions explained how to use it, but I just don't really love it.3. The sound quality seems to be just okay. It's not superb, but I only listen to podcasts, books, and occasionally to music, so I'm not super concerned about that. It's clear enough. It just sounds kind of...far away? Not a dealbreaker to me.All in all, it's decent for what I use it for. I probably wouldn't buy it again, but it works for now.

At first I thought the sound was “foggy” but you have to remember to adjust the tone settings in your car and in the app used for playing the music. For me, I had to make adjustments in Spotify which I had not done. Once I got the tone settings set this sounded just as good as other Bluetooth adaptors I have used, if not better. Also, compared to other products, this one is always on when the car is on since it is in the plug which makes it much more convenient. Other adaptors have to be turned on each time you want to connect. My phone connects as soon as the car is turned on and is super convenient.

Very good quality, great value, works great. Sound is awesome. Charges good.

This item works amazingly well! Highly recommended for cars with no usb connection. Very clear signal and has a good microphone for phone calls
