    FM Transmitter w/ Optional Charging USB Port

    So you love listening to your own music, but don't have an auxiliary port or tape deck in your car? What you need is this FM Transmitter with optional charging from Monoprice!

    This FM transmitter can transmit the selected FM frequency to your car's radio in order to play music from your smartphone or MP3 player. Simply select an open radio frequency on the FM transmitter, and tune your radio to the same frequency. Any music played through the transmitter will play through your car's sound system.

    The transmitter can be tuned to any FM frequency between 88.1 ~ 107.9 MHz at 0.1 MHz intervals. It has a frequency response of 20Hz ~ 16KHz and an effective range of about 5 meters.

    The FM transmitter's 3.5mm plug can be used to connect to most smartphones and MP3 players' headphone jack. It uses your car's cigarette lighter/auxiliary power socket for power, so you don't have to worry about the battery dying during your favorite song.

    The transmitter also includes a USB port that can be used to charge your devices at any time.

    Features:

    • Wireless audio transmission over the entire FM frequency range
    • Works with almost any smartphone or mp3 player
    • Folding 3.5mm TRRS plug

    This is one slick little product. Had it for couple of months and use it a LOT. My truck CD player quit on me and this is greatly prolonging me dropping serious money to replace stereo system. Even use it at home to stream my favorite college radio stations to my stereo system. It's antenna is in the attic and no problem with reception if I'm in den or outside using second zone on patio.

    PROS: 1) When plugged in top of my iphone, it looks like an extension because it is same width and thickness so in effect, making phone 1 3/16" taller.

    2) It holds charge pretty good.

    3) A standard usb cable charges it.

    4) And you can use it while charging too.

    CONS: NONE at all for this product! I hesitate to type it but here goes. The only thing to watch out for, and this would be true with transmitter by anybody, when traveling, you may have to change the radio frequency every 50 miles or so due to radio signal interference.

    Great price and performs well
    I bought this for my son's car, and he says it works great. The antenna on his car is in the rear, so occasionally there is some interference due to the distance between it and the transmitter. But overall this unit performs as well as the ones in the local stores that cost at least 3-4 times as much. Very happy with this purchase, and would recommend.

    PROS: Low price
    Good performance
    Compact size
    Charging port for phone


    CONS: Some occasional interference

    Good transmitter
    I really like this transmitter, but if you're an owner of an iPhone 5 or 5s this is going to annoy you a little. The positioning of the audio jack and this device are not really meant to be together. It ends up looking like a dongle and it's upside down. So if you're ok with that - this is the device for you.

    PROS: Small, easy to use, good quality

    CONS: not for all smartphone models

    Great Product
    Easiest to use of any product of this type I have purchased (I've tried 5 different brands mostly to my dissatisfaction). Very effective. It seems stronger than the others and so much less expensive.

    PROS: Easiest to use

    Very effective. Seems stronger than the others.

    Much less expensive.

    this thing sucks. it really needs the phone to be in some sort of mount to work. it easily falls off my gs3. not a good setup. if it had a cord like the sport head phones it may work better. definitely set it up before you start driving.

    PROS: works sometimes

    CONS: falls off easily

    Works Exactly as Described
    This great little device transforms a basic FM car (or indoor) stereo into your own personal jukebox using just about any portable music player with 3.5 mm output. The addition of a USB port on the charger permits the music player (or smartphone) to be charged while playing. I've had it for about 2 weeks now and it has not failed me.

    PROS: Strong signal to FM stereo

    Additional USB charging port

    Access to full range of FM channels

    CONS: None so far...

    Nice, compact FM transmitter
    This little FM transmitter is great. The plug flips out and it just sits on top of the 3.5mm headphone port on whichever device you're using. I can see this being a problem if you have a thick case around your device, but seriously, buy an extension cord or adapter if that's an issue. I'm that is the problem with most people saying that it doesn't stay in, because I have no problem with mine when it's flush with the port.



    The audio quality is definitely acceptable for an FM transmitter. The signal strength is fine especially considering I live in a large city with lots of radio stations and my car is missing its FM antenna.



    Every other FM transmitter I've owned has had one issue or another. Either the signal isn't strong enough, the battery life is bad, turns off when the volume of the music gets too low, etc. But this one doesn't seem to have any of those problems, and it's cheaper than most of the other ones I've had. Definitely a good purchase.

    PROS: Very compact

    Good battery life

    Standard MicroUSB charging port

    Strong enough signal

    Good audio quality

    Does not turn off randomly when volume gets low like others I've owned

    CONS: So small that I lost it once, but I found it again! Yay!

    There has got to be a better way...
    I tried to use this device in my car while driving in a location. (LA area) I was never able to find an FM channel quiet enough to make use of this device. There was always interference. I found the device would shut itself off in seconds if the audio stream disappeared. Auto shutoff in minutes would have been better.

    PROS: Small and light enough to use the 3.5mm jack as a mount.
    Reasonable battery life.

    CONS: FM signal relatively weak.
    Shuts itself off within seconds if the audio stream ends.

    FM Transmitter w/ Optional Charging USB Port (10403)
    Never got to try functionality because the phone case is a show stopper.

    CONS: 3.5mm jack does not fit in my phone because of the phone case.

    Great product for the price

    PROS: Flawless sound and connectivity

    CONS: If you have a larger case for example an otter box you'll have to take the phone out or use a extension so the transmitter will fit into the stereo port
