8 Best FM Transmitters for Cars in 2018

FM transmitters, in being essentially adaptive devices, can be put to use in many different ways. In this modern era, when many have found ways to work from the comfort of their home or any place that best suits them, sending communications out is vital, and that includes doing so through radio waves as it does through phone calls and sending emails via the internet. When it comes to their use in cars, however, their use is transformed from that of work-related utility to that of practical enjoyment.

This is because they take a car’s old music playing system, one that doesn’t have the necessary entries to allow music players such as cell phones and MP3’s, and allows it to play music through such devices via FM transmission. Even if some amount of connectivity is possible between a car’s music player and a user’s own device, having one of these is still handy as no wires are involved, meaning even greater convenience in use.

The best FM transmitters have a number of features that include being suitable to as many devices as possible, transmitting as far as possible, how clearly they transmit what they do, as well as making use safe for both the driver and the devices used.

1. Nulaxy FM Transmitter – Radio Adapter


Nulaxy FM Transmitter – Radio Adapter

Once connected to its power source, the cigarette lighter of a car, the Nulaxy FM transmitter works without any wires needed. Its Bluetooth feature allows for connectivity with any other Bluetooth device, including all types of smartphones and tablets, among other devices with Bluetooth. It is not exclusively suited for such devices as it can also be connected through its 3.5mm audio jack, making it suitable for an even broader range of audio devices such as MP4 and MP3 players. The large LCD screen displays functions as users easily control use either through their audio playing device or with one of the four fitted buttons, not including the multi-function button at its center. It also includes a built-in microphone for hands-free use, a USB port that can charge just about any mobile device, a microSD card slot, and an AUX input and output support.


  • Kit includes 3.5mm cable
  • Can be used for incoming phone calls
  • Supports various audio formats
  • Flexible arm allows for convenient positioning


  • Some static audible
  • No power off button


Some minor shortcomings prevent this FM transmitter from being as complete as it can be, but given all that it can do, and the incredibly convenient way it can do all that has been explained, the utility of the Nulaxy Wireless FM Transmitter is unquestionable.


2. LDesign Bluetooth FM Transmitter

LDesign Bluetooth FM Transmitter

This L-shaped transmitter is not only sleek in design, but measuring only 2.9 oz., the compact device is made to provide the utmost suitability in its dimensions, and where it can fit, as well as in its multi-functionality. It is Bluetooth enabled, making it suitable for a wide range of mobile devices, and this suitability is extended to devices without Bluetooth via a TF card slot and a USB port that work just as well. The latter, with a 5V/2.5A energy output, serves well to charge mobile devices in a safe way by detecting how much output is needed and regulating it so as to protect the device. The transmitter has a built-in microphone that allows users to pick up calls and speak without taking their hands off the wheel.


  • Hi-Fi stereo sound quality
  • Suitable for multiple devices
  • Hands-free calling
  • Charging device


Sporadic automatic voices interfere with music


Despite some glitches in how it functions, users will have little to complain about once the LDesign FM transmitter is connected to their car through the cigarette lighter and playing their favorite tunes with clarity. Its compact size and light weight are just two of many aspects to be appreciated in this uniquely designed product.


3. VicTsing Bluetooth FM Transmitter

VicTsing Bluetooth FM Transmitter

The VicTsing’s features are just as sophisticated as the FM transmitter’s design promises it to be. The large LCD display does more than just display the name of the song that is playing, but it also shows the name of a caller if a phone is connected and, as a unique twist, it can also show the voltage of a car’s battery. Not forgetting its main function as an adaptive transmitter, it features Bluetooth, a memory card slot, and an AUX port, all of which make it suitable for a plethora of mobile devices that users can play music from once the device transmits to the car’s FM player. The device is also easy to use, and for those on the road, a large center button in the middle of a piece with a flexible arm makes it easy to take phone calls. Among its many functions is the ability to charge a mobile device through its 5V/2.1A USB port.


  • Compatible with various devices
  • Multiple functions
  • Fast charging capability
  • LCD screen with various displays


Built-in microphone mediocre


This is just another example of why FM transmitters are great accessories to have in a car, even though the car’s radio player has options to allow users to connect their mobile devices, the sheer number of features the VicTsing has makes it invaluable, and not something you can easily find.


4. Nulaxy Wireless In-Car Bluetooth FM Transmitter


Nulaxy Wireless In-Car Bluetooth FM Transmitter

Able to receive data in three different ways, either through its Bluetooth compatibility, the 3.5mm audio jack, or one of its two USB ports, all of which mean that the Nulaxy FM transmitter is able to adequately transmit sounds to any car stereo from practically any audio-playing device. It supports both MP3 and WMA sound formats, enabling it to read the vast majority of audio formats music and transmissions are saved in. The built-in microphone also supports live audio streams that allow users to speak on their phones as well as use the transmitter as a form of broadcasting. All these functions are helped by the large LCD screen and 7 easy-to-access buttons that make using the transmitter quick, and for those handling the wheel, safe as well. The transmitter comes with not one, but two USB ports, allowing users to charge compatible mobile devices in an equally safe and convenient way.


  • Compatible with most devices
  • Supports A2DP
  • TF/MicroSD card support
  • Dual USB ports


Slightly bulky


The device’s size can be excused once users realize just how much it can do, and for how long it can perform its functions, considering its overall durability. The best thing about the Nulaxy Wireless In-Car Bluetooth FM Transmitter, however, is that once bought, it almost guarantees no regrets as it is able to play from any device, even a flash drive.


5. Nulaxy KM19 FM Transmitter


Nulaxy Wireless In-Car Bluetooth FM Transmitter

Almost as a compact solution to the company’s great-but-large FM transmitter, the Nulaxy’s KM19 manages to pack a lot of features into a device that is hardly noticeable once connected to the cigarette lighter of a car. Among its long list of functions, the device’s transmitting range starts from 87.5MHZ all the way to 108.0MHZ, playing MP3 and WMA files, or what is captured with its inbuilt microphone. Files can be played through any device that either supports Bluetooth, a 3.5mm audio jack, a TF or MicroSD card, or from a USB flash drive with compatible audio files stored on it. It has a second USB port, with a 5V power outlet, enough to supply power to any mobile device while on the go. The LCD screen, with a backlight that makes it visible in the dark, also reads incoming caller IDs and the voltage of the car’s battery.


  • Compact and lightweight
  • Multi-functional
  • Easy to use
  • 2-meter range


Audible static


It could do with better sound quality, but other than that, this little device is akin to that of a magical hat, producing much more than one could possibly expect from it.



6. JETech Wireless FM Transmitter

JETech Wireless FM Transmitter

Able to connect to various devices that can support its 3.5mm audio jack, this sleek device is able to transmit audio files to a car’s FM receiver, once connected to a cigarette lighter. The length of the device means that it is easy to reach and access the two button controls that make shuffling through files a quick affair. Somehow, it manages to fit a USB port to the cigarette lighter end of the piece, allowing users to charge their mobile devices.


  • Complete kit with manual
  • Light and easy to access
  • USB port for charging


Not very durable


The Jetech’s design is enough to make it an attractive option for anyone looking to buy an FM transmitter, but the fact that it performs the essential functions just as well as any other, all while offering an unparalleled compatibility and flexibility, simply makes it one of the best.



7. VicTsing FM Transmitter

VicTsing FM Transmitter

As a more compact version of the previously listed VicTsing FM transmitter, this manages to rival its sibling model by offering much of the same features, though presented in a different way. Able to read an impressive 3 different audio formats, namely MP3, WMA, and WAV audio files, adaptability is guaranteed to the user looking to transmit to their car’s FM receiver. The way in which it receives these files is even more diverse as it can receive via Bluetooth, a 3.5mm audio jack, a micro SD card, or a USB flash disk. A volume control, along with four other buttons, fits neatly underneath the 1.44” LCD screen that displays the music playing along with the ID of an incoming call when a phone is paired. An extra 5V USB port allows for compatible devices to charge in a quick and safe way. The transmitter’s smart technology has a memory function that allows it to auto-connect to the last paired Bluetooth device to provide even greater convenience.


  • Supports multiple formats
  • Supports multiple devices
  • Flexible neck
  • CVC noise cancellation
  • 5-meter transmission range


Bluetooth range poor


There are few transmitters that offer as much as this does, and after comparing it to the similar model made by the same manufacturers, it is fair to say that this does as much as is possibly imaginable to edge out its rival, not to mention other competition that is beaten fair and square.



8. LDesign Bluetooth FM Transmitter – Gold

LDesign Bluetooth FM Transmitter – Gold

As an adaptive device, the LDesign’s Gold FM Transmitter meets all the expected needs, including being hospitable to Bluetooth-enabled audio players, a USB flash disk port, and a TF card slot. It automatically plays MP3 tracks to a car’s receiver with an echo-free CVC noise cancellation technology to ensure the best sound. Once connected to a car’s standard cigarette lighter, its 5V/2.5A USB charger provides enough power supply to quickly and safely charge a number of mobile devices. The featured microphone enables hands-free use to allow users to speak on the phone while driving.


  • Smart and safe charging
  • Compact and lightweight
  • Hands-free use


Limited functions


Given the size, and light weight, this transmitter does enough to make it into the list of the best adapters for a car, as it does not neglect any of the essentials while also being as convenient as possible despite its rigid design. The gold color it comes in is a great plus.




Transmitters come in many fun and creative designs, but despite their playful look, the actual application requires a blend of practicality and demanding functions that make it necessary to carefully choose only the best.

All of the transmitters on this list manage to cover all the essentials when addressing overall quality, while also doing their best to pack as many handy functions as possible. As evidenced by all of the above, such feats are possible, making life easier, safer, and with the interesting shapes available, much more interesting.
