JOYROOM Universal Bluetooth car adapter and FM transmitters

Written By Darryl Reviewed By Accessories 5 Min Read

There is an abundant number of car chargers available in the market. But unlike others, the Joyroom car charger features dual fast charging USB ports, Bluetooth 5.3, an FM transmitter, dual mics, AUX output, and more. We have the charger with us, and here’s our review.

JOYROOM car adapter review: Utilitarian design and build


The Joyroom car charger has such a vast feature set that it confused me about where to begin with. Also, it is compact and weighs only 44 grams, which further assures me that the device won’t fall out during bumpy rides.  

Let’s look at all its features in a 5×4.5×7 cm form factor. It displays Bluetooth status, bass mode, and the voltage or FM radio frequency. When you plug this device in, you’ll notice LED lights turn on, which you can control with the button at the left of the device, and the display panel comes to life.  


Above the display are a pair of microphones that assist in hands-free calling. These microphones also come with the latest CVC 8.0 noise reduction technology that helps block a range of wind and traffic noise, ensuring a clean calling experience.  

Below the display, we have a USB-C port and a pair of USB-A ports. On the topic of ports, the device also features an AUX out port that helps you connect the device to the car’s stereo and play music via Bluetooth (Version 5.3) or through the second USB-A port, which supports a flash drive. The AUX port outputs CD-like audio quality.


The Bass and call receiver buttons are beside the ports, which also function as the FM radio frequency scroll wheel and volume control. There are previous and next buttons on the right side of the unit to skip to the next song or repeat the previous song. To the left, we have a button that controls the LED light, just below the AUX port.  

How to access FM Radio

How to access FM Radio in JOYROOM car charger

If your car stereo lacks FM Radio support, the Joyroom car charger is the perfect solution for you. It can help you connect to the radio and stream the audio through the car’s audio system. This is made possible thanks to the AUX output port that outputs CD-like quality music.  

You need to press and hold the knob below the bass button to enable the FM radio mode. Rotating the knob tunes the FM radio frequency shown on the device’s displays. Also, the knob doubles as a scroll wheel. There are multiple ways to connect to FM Radio. Head to the Joyroom website, which lists all the ways to connect to FM radio.

48 watts of Power Delivery 

The Joyroom car charger houses a USB-C PD port that delivers up to 30W of power and the QC 3.0 USB-A port with a maximum power output of 18W. Here are the power ratings for both the ports: 

  • USB-C PD port: 5V=3A,9V=3A,12V=2.5A,15V=2A,20V=1.5A (Max 30W) 
  • USB-A QC 3.0 port: 5V=3A,9V=2A,12V=1.5A (Max 18W) 

Connecting your iPhone through the USB-C port can charge your iPhone at 20-25W. It means your iPhone will charge from 0-50% in 30 minutes. The USB-A port is also certified Quick Charge 3.0, ensuring 18W of maximum power output. Again, you can expect almost 0-50% battery in 30-45 minutes.  

Even when both ports are occupied, the total maximum power output by the Joyroom car charger is a whopping 48W. Connect your Mac and your iPhone to the Joyroom car charger and get almost full charging speeds with it.  

Is the JOYROOM car charger worth your money?

The Joyroom car charger is priced at $24.99. One could argue that you can get 2 car chargers for that price. But that is only partially correct as this isn’t only a car charger and has a set of other useful features. It does everything from charging your gadgets to working as a Bluetooth receiver.

Tired of neutral sound and want to listen to bass-heavy music? Press the bass boost button, and the audio completely changes. If your car doesn’t support wireless calling, the Bluetooth functionality of the device helps enable this feature.
