Review: Just awesome - Absolutely incredible product! It's small enough to fit in your pocket. Transmits audio and a microphone to the radio. I use mine to run my mobile drive-in theatre, and it works flawlessly. I love this product so much, that the urge to buy another one, even though the original product is in perfect working order, (just in case) is strong. I do not understand how anyone could possibly be disappointed in this product. From the quality, to the price, what else do you need in a perfect product?
Review: The SD slot and digital audio PC link are a nice touch but the power out settings can't be trusted. - There are a lot of things to like about this device. - It is small compared to almost any other FM transmitter in its class And has a rechargeable 2000mAH battery that will power it for around 6 hours or more - The antenna screws into a reverse type SMA connector that may require an adapter to connect to regular SMA connectors - Using the SD card to play songs from can eliminate any hum problems as does the digital link over USB and you can set Random mode in SD play - The unit has a builtin mic you have to yell into to be heard and a separate mic input and comes with the external mic as well - It has a setting for Preemphasis of 75uS or 50uS. 75uS is used in the US but after trying both settings I can't hear any difference for whatever that is worth. - The overall sound quality is excellent, and hum free (actually best to keep antenna away from your other electronic equipment - like on the roof). - Lastly I measured the power output on this and found it was outputting 0mW on setting 0 and 1, then 230mW on setting 2, and 210mW on setting 3. I got so curious I bought a second one and measured it: - The second one outputs 0mW on 0, 191mW on 1, 330mW on 2 and 365mW on 3. Kind of nonsensically spaced power levels. So if you are trying to follow FCC rules - measure the power out of this thing and make sure it is under 100mW before connecting an outside antenna. - If you use the little antenna that comes with it, it is tuned for 91MHz +- 1MHz, and is a terrible antenna for the rest of the FM band - Controlling the device is dirt simple using the intuitive keypad Cons: - Did I mention it comes with a terrible antenna? - You won't know how much power it puts out unless you measure it.

### ⭐⭐⭐⭐ Save the Instructions Becuase They Are in English!!
*by S***S on November 13, 2024*

I really like this thing! I use this FM Transmitter with the TF card option during the holidays to play seasonal music to as atmosphere to holiday displays. I sometimes use is in my work truck so I can play my music any where I go. The FM Transmitter has a lot of other features though I generally don't use them, so I can't vouch for how well they function. The device it self has decent clarity of signal and a much greater range than I thought originally (as it goes half a block or so). The battery life has been around 3 hours. But plugin in the charging port I have gotten over 8 hour of playtime! HOWEVER, My biggest complaint is that the unit will sometimes revert to the CHINESE language suddenly and totally. Everything is in CHINESE. As I don't speak CHINESE at all, this is a problem. I suspect I have hit some combination or some magic button that instantaneously turn every word in to CHINESE. I wish I knew what I am doing but I have had the FM transmitter revert to CHINESE a few times now and it is frustrating. But, I saved the instructions and if you very, VERY carefully follow the menu STRUCTURE (as everything is in CHINESE at this point) you can find the option that will change the language of the FM Transmitter from CHINESE into English. I would keep the instructions handy for this reason. If this fm transmitter would stop showing CHINESE this would be a Five-Star review. All-in-All It is a really great item for adding more Happy to the Holidays! Recommend!! *Highly Recommended if you can speak CHINESE!!
