Wasn't sure it'd work in my '11 Civic but I needed something fast and it actually fixed the problem. Can listen to my music bluetooth and the fast charging works well

Bluetooth FM Transmitter Car Charger Kit
The light's actually useful
Didn't care about the light until I tried plugging my charger in at night and could actually see the ports.
Perfect for college cars
If you just got handed down a car with no aux and you're tired of the radio, get this. Works in like 30 seconds and you can charge your phone at the same time.
Skeptical but glad I tried
I thought it was gonna sound like trash through FM but I was tired of the aux cord situation. Found a clean station and honestly it's way better than I expected. Now I can charge my phone at the same time.
Drove to work with actual music
I haven't listened to music in my car in like six months because my aux cord died and I kept forgetting to buy a new one. Plugged this in on my lunch break, found 88.1, and had Spotify going before I left the parking lot. Now I actually look forward to my commute instead of just sitting there in silence or listening to the same three radio stations.
Actually sounds fine once I found it
I was nervous about the static everyone talks about but the sound's totally clear on 88.1 in my area, better than my old aux cord honestly.
Perfect for Uber shifts
I drive for Uber nights and weekends in a 2012 Civic and I'm constantly switching between my phone, my passenger's aux requests, and keeping everything charged. This thing solved all three problems at once. Navigation comes through clear, I can charge my phone and a backup battery at the same time, and passengers don't have to mess with a cable anymore.
Didn't know it lit up at night
I just needed Bluetooth but the light around the ports actually helps me find stuff I drop at night. My car's interior light is garbage so this is kind of perfect.
If your car's from 2012, get this
I got one for my son when he started using my old Honda and honestly I wish I'd known about this years ago. If you've got a car that still works but has no aux or Bluetooth, this is exactly what you need. He can charge his phone and play his music without me paying for a new stereo. Took him like two minutes to set up and he's been using it every day since.
Figured worst case $20
Had one years ago that sounded awful so I almost didn't try this but honestly it's fine if you find the right station.
Instant Bluetooth & Fast Charging for Your Older Car, No Stereo Swap Needed
Your car already has everything it needs.
Your 2012 Civic has a working radio and a 12V socket. No Bluetooth. No aux input that hasn't broken off inside the port already.
This transmitter plugs into the lighter socket and turns the FM radio into a Bluetooth receiver. Pair your phone once. Navigation, calls, and playlists come through the car's existing speakers.
The same socket that used to hold one charging cable now handles wireless audio and charges three devices at the same time. Two USB-A ports and one USB-C port sit on the face of the unit.
Setup is three steps and takes thirty seconds. Plug the unit into the socket. Tune your car radio to match the FM frequency shown on the built-in LED display. Pair your phone via Bluetooth. Physical buttons on the unit answer calls and skip tracks so your phone stays in your pocket.
Plug in and pair in thirty seconds.
Two USB-A, one USB-C charging ports.
Hands-free calls via built-in mic.
Why This One Sounds Better
This transmitter scans the full FM band to locate genuinely empty frequencies, applies noise filtering to the audio stream before broadcast, and maintains a stable Bluetooth connection through stop-and-go traffic for consistently clear sound.

Turn the lighter socket you already have into wireless audio and three-port charging. No new stereo, no aux cable, no second trip to the parts store.
Your car has no Bluetooth. Just a radio.
You leave the house with a playlist ready and park forty minutes later still on podcast episode three because your aux cable died six months ago and you never replaced it. The radio works fine. It just can't talk to your phone. This plugs into the lighter socket and turns that FM radio into a Bluetooth receiver in thirty seconds. Your music plays through the car's own speakers without touching the stereo, pulling a cable across the dash, or waiting for an install appointment.
How to set it up in your car
1
Plug In
Insert the unit into your car's 12V or 24V cigarette lighter socket.
2
Tune the Radio
Match your FM radio to the frequency on the LED display.
3
Pair Your Phone
Connect via Bluetooth. Music and calls play through car speakers.
Three ports. The socket you gave up for charging now does both.
Two USB-A and one USB-C port sit on the face of the unit. Your phone, your passenger's phone, and a dashcam all charge at once from the one socket that used to hold a single cable. The wireless audio runs at the same time.

Bluetooth FM Transmitter Questions
How clear is the audio through the car speakers?
+
Audio clarity depends on finding a genuinely empty FM frequency in your area. The unit transmits over FM the same way a radio station does, so once you locate a clean frequency with no competing signal, music and calls come through your car speakers at full FM radio quality. The built-in LED display shows the current frequency, and you can adjust it to find the clearest channel wherever you drive. Start at the low end of the FM band (87.9 to 89.9) where stations are typically spaced further apart.
What if I get static or interference?
+
Static means the frequency you selected is already occupied by a radio station or another transmitter in your area. Switch both the unit and your car radio to a different frequency until you find one with silence when no audio is playing. Urban areas have more crowded airwaves, so you may need to test several frequencies, but once you locate an empty one, it stays clear for that location. The frequency adjusts on the unit itself, and your radio tunes to match.
Does this work if my car only has one cigarette lighter socket?
+
Yes. The transmitter plugs into that single socket and replaces it with two USB-A ports and one USB-C port on its own face, so you gain wireless audio plus three charging ports where you previously had just the empty socket. One plug handles Bluetooth audio and multi-device charging simultaneously.
Will this work in my older car that doesn't have Bluetooth or an aux input?
+
If your car has a working FM radio and a 12V or 24V cigarette lighter socket, this works. The unit turns your existing radio into a Bluetooth receiver, so any car from the FM radio era forward gets wireless audio without replacing the stereo or adding an aux cable. Setup is plug in, tune the radio to match the transmitter's frequency, and pair your phone.
Can I answer calls through this without touching my phone?
+
Yes. The unit has a built-in microphone and a physical call answer button on its face, so incoming calls play through your car speakers and you respond hands-free. Your phone stays in your pocket or bag. The microphone picks up your voice from the driver's seat, and the button ends the call when you're done.
