Rexing FMT2 Fm Transmitter Car Charger
Your car’s head unit is dead, or the AUX port is buried under a decade of plastic trim you can’t reach, and you still need to hear your phone’s navigation or a podcast while you drive. The Rexing FMT2 Fm Transmitter Car Charger solves that specific friction by plugging into your 12V outlet and broadcasting your phone’s audio over the FM band your radio can still receive. It is not a Bluetooth receiver for a modern infotainment system; it is a bridge for older vehicles that lack digital inputs. If your car has a basic FM radio and a cigarette lighter socket, this device turns your phone into a stereo source without rewiring the dashboard.
| Best for | Older vehicles with no AUX port or Bluetooth, drivers who want hands-free calling and music via a simple plug-in device. |
| Skip if | Your car has a built-in Bluetooth receiver, a USB media port, or a modern head unit with Apple CarPlay/Android Auto. |
| One line | A Bluetooth 5.0 FM transmitter that plugs into your 12V outlet to stream audio to your car’s radio. |

What the Official Page Lists
Rexing positions the FMT2 as a fast-charging, hands-free calling device with enhanced bass and stereo music capabilities. The brand states that they design, test, and manufacture their devices to guarantee reliability and longevity. Key features highlighted on the product page include:
- Bluetooth 5.0: For stable connectivity with modern smartphones.
- USB Music Player: Allows direct playback from a USB drive (in addition to phone streaming).
- Voice Control: Supports hands-free operation for calls and music.
- Analog/Digital Display: Shows track info and call status.
- Fast Charging: The USB port provides faster charging speeds for your phone while driving.
Rexing backs its products with US-based customer support and an industry-leading 18-month free replacement policy. While specific battery capacity or output wattage figures are not explicitly detailed in the fetched snippets, the "Fast Charging" claim suggests a higher amperage output than standard 1A chargers. Verify the exact amperage (e.g., 2.1A or 2.4A) on the product packaging or brand site to ensure it meets your phone’s charging needs.
Who It's For
This device is a practical solution for drivers stuck with legacy audio systems. It is ideal for:
- Drivers of pre-2010 vehicles: Cars that have a functional FM radio but no Bluetooth or AUX input.
- Fleet and ride-share drivers: Who need reliable hands-free calling and navigation without complex head unit installations.
- People who want a simple setup: If you just want to plug in, pair your phone, and drive, the FMT2 requires no installation or coding.
- Users who value the display: The analog/digital display helps you see which track is playing or who is calling without looking at your phone.
Who Should Skip
If your car already has modern connectivity options, this device adds unnecessary clutter and potential interference. Skip it if:
- Your car has Bluetooth: Most cars from 2015 onward have built-in Bluetooth. Using the car’s native system is usually clearer and more stable.
- Your car has a USB media port: If you can plug your phone directly into a USB port for audio, that is generally superior to FM transmission.
- You live in an area with heavy FM congestion: FM transmitters work by finding an empty frequency. In dense urban areas, it can be difficult to find a clean channel, leading to static or interference with local radio stations.
- You need high-fidelity audio: FM transmission is lossy. If you are an audiophile, this will not replace a direct digital connection.

If the criteria already match how you live in the space, see current options before you keep comparing.
- Check your car’s inputs: Look for an AUX port, USB media port, or Bluetooth button on your head unit. If you have any of these, you likely do not need the FMT2.
- Verify your 12V outlet: Ensure your cigarette lighter socket is functional and located in a convenient spot. The FMT2 is a plug-in device, so it will occupy that port.
- Test FM availability: Before buying, tune your car radio to an empty frequency (one with no station) to ensure you have a clear channel. If every frequency is occupied by a local station, the FMT2 will struggle.
- Consider the charging speed: If you use your phone heavily for navigation, check if the FMT2’s fast charging meets your phone’s requirements. If your phone requires a very high wattage (e.g., 20W+), a standard FM transmitter may charge slowly.
- Review the warranty: Rexing offers an 18-month free replacement policy. This is a strong safety net for a device that will be plugged in daily.
