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.

Update: this device has its own volume. If you turn that volume all the way up the high pitch noise stops. Figured it out while my husband was driving recently, couldnt pick out a new one fast enough lol. After my review the seller offered to refund but it’s working fine now. That noise was stressful tho especially when you dont know where it is coming from.Old review:Makes a high pitch whining noise that gets worse when you accelerate. So annoying! Freaks you out too until you figure out where it is coming from. Started after a month, cannot return. I hate it so much im shopping for another 2 months later. Do not buy.

I have a 2012 Honda Accord and I am a Android user I'm so happy that I don't have to use my Aux cord anymore!! The sound is awesome set up is easy calls are clear and the price is right.

It works great! 1 minute setup and phone calls are crisp and clear!So glad i got it, extremely happy with the ease of install. Literally it took1 minute to set up and it works beautifully! I totally recommend it, especially for the price!

SO FAR GREAT ! I DID HAVE TO TWEEK MY SOUND SETTINGS IN THE CAR. BUT MOST IMPORTANT HAD TO FIND A RELATIVELY STATIC FREE AND VACANT FM FREQUENCY, NOT AN EASY CHORE IN A MAJOR METRO AREA

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 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.
