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.

I purchased this device for a 1989 Buick LaSabre. It has a nice compact size, the directions make it very easy to use and navigate the radio to the Bluetooth connectivity on my phone and it charges the phone relatively fast despite the car's age. I can't really comment on call quality because calling someone while driving will automatically mess up your service depending on where you're driving.

I bought this item because it said high powered. Apparently that was meant for its ability to charge other things rapidly. I wanted it to help raise the volume of the stereo. It didn’t raise the volume. Outside of that one issue it does connect easily, shows the amperage of the alternator on startup and plays very well for the price just not for the specific reason I bought it.

Works great, have an older work vehicle with no Bluetooth. It's very important bc I make calls while on the road all day and having this FM transmitter makes it as if I'm driving a newer model vehicle. No issues with linking up or playing my Spotify

I have a 2009 Honda Pilot .Great for older cars that don’t have the built in Bluetooth.one thing that I love about this product is that there is no noise in the Bluetooth I have purchased many with a lot of background noise ! This by far is the best!

This is an amazing product the bass is incredible and you can turn it off whenever or turn it on when you want to the sound is so much better and my radio doesn't static anymore over all I think everyone should have one in their cars for just a better stero. I've had people come up and ask me what stero I have and I've only had it a couple hours. If there was 10 stars I would rate it that. Definitely would buy.

The media could not be loaded. Decent product, does the job with a very compact design that fits neatly in my console. A few things:- setup was easy. I did need to consult the little manual that comes with it, but after doing it once it’s pretty easy to remember should I ever need to do it again.- as I mentioned, very compact design. I had purchased a different product previously which required me to connect not only to the cigarette lighter but also to my car’s headphone jack, leaving a mess of cables hanging by my gear shift. This product connects completely through Bluetooth and broadcasts through a blank radio station of your choice. Easy, quick setup.- two usb ports on the product itself are a nice touch, and the customizable lights and digital readout give it a high-tech look.The negative:- I’m not entirely sure, but I *think* the usb ports charge more slowly than my standard usb. I’ll have to check again after a long drive.- the sound quality is a little iffy and might require some more tweaking on my part to get the right sound balance. Still better than nothing since my car doesn’t have an integrated Bluetooth system. Also, the bass-boost seems like overkill and I end up with muddled, heavy bass that interferes with most of the sound.- the microphone might be lacking if there’s considerable background noise. Again, I’ll have to keep using it to be sure. Again, better than not having anything.Finally, there’s an odd little glitch that I should point out: I left my car at one point and tried locking the doors with my key remote, and it didn’t work. I kept hitting the button on my key fob and still nothing. I figured it was a dead battery. Later the same day, I left my car again and suddenly the remote worked. Again, later the same day I left my car, hit the buttons and ended up having to manually lock my car. This on-and-off kept happening for a couple of days.I finally figured out that my remote wouldn’t work if I left the Bluetooth adapter plugged into the cigarette lighter. It was interfering with my remote somehow. So, I have to remember to unplug it before I leave the car. Not a deal-breaker, but a little inconvenient.Still an overall decent product.
