Top 5 Best FM Transmitters for Cars In 2022 Review

1 Anker Roav – Latest Tech FM Transmitter for Cars

This little beauty from Anker plugs directly into your power source (previously known as the cigarette lighter). It is compact, easy to use, and offers a great range of features beyond transmitting an audio signal to your radio.

Installing the transmitter is easy. Once plugged into the car’s socket, the transmitter is then receiving power. Connect your smart device using Bluetooth, then tune your radio to the same FM frequency displayed on the transmitter. Easy as that.

Beyond the transmission…

Not only does this transmitter send an audio signal, but it can also charge your device. There is both a USB 3.0 port and a USB Type-C port, both of which can provide fast-charging to your smartphone or tablet.

Because the transmitter has a built-in microphone, you can make and receive hands-free calls. Sound quality is amazingly clear thanks to noise-canceling technology that blocks out background noise while on a call.

Forming a strong connection…

Pairing your device to the transmitter uses the latest Bluetooth 5.0, ensuring a clear and stable connection. The signal between the transmitter and your stereo has also been enhanced, providing minimal interference.

Automatic channel scanning from the transmitter searches for the clearest FM frequency with the least interruption or interference. Functions such as answering calls and skipping tracks can then be controlled using the buttons on the transmitter.

2 Tecboss – Best Custom Mount FM Transmitter for Cars

Next up in our best FM transmitters for vehicles review, we have the Tecboss. Just like the Anker transmitter, power is sourced from your car’s power socket. Only, the Tecboss has a cable allowing you to mount the controls in a convenient place of your choosing.

Mounting options include clipping the controls onto your air vent or using the included adapter to stick it to your dashboard. Pair your device to the transmitter using Bluetooth, then the transmitter to your car stereo via the FM frequency.

Full power ahead…

Located at the end of the power plug are two USB 3.0 ports. Both offer 5V 2.4A power, which can provide fast charging to two devices simultaneously. Therefore, both driver and passenger can keep their batteries topped up whilst on the road.

A built-in microphone allows for calls to be made hands-free. There is an answer button located on the controls, or for a truly hands-free experience, both Siri and Google Assistant are compatible.

Multiple source options…

Besides using Bluetooth, there are two other options available. You can connect a 3.5mm Aux cable into the port on the control. Additionally, located on the opposite side is a Micro SD card slot, which can be used to play audio files.

For clear and stable signals, the Tecboss uses Bluetooth 5.0 to connect the transmitter to your device. The microphone also features noise cancellation to eliminate background noise while making phone calls.

3 WPWPOO – Best Rotating FM Transmitter for Cars

Coming back to the direct plug-in style transmitter, here we have this product from WPWPOO. To keep this transmitter tucked away and streamlined, it features a rotating design that covers the USB ports when not in use.

By rotating the face to the right, it exposes two 5V 2.4A USB fast charging ports. The hands-free/call button can still be accessed, and the LCD display that shows the radio frequency still remains visible.

Hands-free calls…

Calls can be made/received using the built-in microphone with noise cancelation. This lets the driver concentrate on the road without needing to hold or look at their phone. The audio automatically pauses during a call, then resumes once the call is disconnected.

Just like the other direct plug-in transmitters, it slots straight into your car’s power socket. The transmitter then sends a radio frequency to the FM radio. You can connect your device using the integrated Bluetooth 4.2 wireless connection.

Beyond Bluetooth…

Besides Bluetooth, on the right side of the transmitter, there is a Micro SD card slot. A second option for playing audio through your car’s stereo is offered by inserting an SD card containing audio files.

On the transmitter’s left side, there are two buttons that can be used to skip tracks. It can be a touch tricky to locate at first, and they are a bit small. Once you are aware of their placement, it does become easier to access over time.

4 Doosl – Best Wireless Portable FM Transmitter for Cars

And now for something completely different. This transmitter from Doosl is entirely wireless and portable. Not only can you use it in the car, but it will easily fit in your pocket to be used anywhere there is an FM radio.

Thanks to the built-in 700mHa rechargeable lithium-ion battery, it can be used anywhere. From a full charge, you can enjoy up to 10 hours of playback. Charging is completed using the included USB cable.

Enjoy your audio almost anywhere…

Just like the other products, your device connects to the transmitter using Bluetooth. Once your device is paired, you can then connect the transmitter to any FM radio by matching the frequency displayed on the LCD screen.

Pairing your device does use the older Bluetooth 4.1 technology. This isn’t as stable over long distances, so you will need to keep your device close to the transmitter. However, because the transmitter is so tiny, this isn’t too big an issue.

Driving directions…

Although there is no built-in microphone, you can still utilize other functions from your smart device. When using map guidance, you will hear directions played through your car’s audio speakers.

This does, unfortunately, mean that you can’t make or receive phone calls with this transmitter. Still, if you like the idea of being able to bring your transmitter wherever you go, this might be something you’re willing to sacrifice.

5 JETech – Best Aux Connect FM Transmitter for Cars

For our final product, we have something different again. The JETech does not use Bluetooth connectivity. Instead, it uses the old 3.5mm auxiliary cable. That means that your smart device will require a headphone jack. Sorry iPhone users.

There is a choice of three different colors, being black, gold, or rose (pink). At one end is the power supply followed by a length of cable. A small control unit has an LCD display showing the radio frequency, followed by some more cable with a 3.5mm plug at the end.

Easy to prepare…

Setting up is very simple. Plug the power supply into your car’s power socket, and the 3.5mm plug into your device. Then all you do is tune your FM radio to the same frequency that is displayed on the LCD screen.

At the end of the power supply, there is a 5V 2.1A USB port that can be used to charge your device. This is slightly lower amperage than the USB ports on the other products but will still offer a decent charge relatively quickly.

Impressive sound quality…

All of these transmitters suffer from varying levels of volume loss. This is simply unavoidable with these transmitters. However, because there is a direct connection via auxiliary rather than Bluetooth, the volume loss is less of an issue.

There is no support for phone calls due to the lack of an in-built microphone. Even though this is lacking, the compact size and excellent audio quality should make it worth your consideration.

Best FM Transmitters for Cars Buying Guide

We have now shown you a range of different products that all offer the same function in slightly different ways. If you weren’t aware of these products previously, you probably can’t wait to make a purchase.

Before you do, though, make sure you read out our buying guide. We will identify the main differences between each product so you can make the most informed decision possible. That way, you can get the absolute best out of your new gadget.

Compatibility

Most, if not all, smartphones have a Bluetooth connection these days. The same goes for tablets. Even most PCs offer Bluetooth as a connection option now too. That means that four out of the five products will most likely be compatible with your device.

If you prefer additional options, both the Tecboss and the WPWPOO offer playback via a Micro SD card. The Tecboss also offers 3.5mm auxiliary connectivity, as does the JETech; however, the JETech misses out on Bluetooth.

Your car’s design

Depending on the layout of your car, the power socket may be in an inconvenient location. If this is the case, it could make it difficult to plug in a USB cable or access the controls on the transmitter.

That is where the Tecboss or JETech will be helpful, as you have more options of where to mount the controls. The Doosl might be even better for you due to being completely wireless. But keep in mind, you will miss out on phone call capability.

If you’re still finding it difficult to make a decision on which product will suit you most, stick around. In our next section, we will reveal what we think is the best FM transmitter for cars out there and why.
