ROAV SmartCharge F2 Bluetooth FM Transmitter, Wireless Audio Adapter and Receiver, Car Charger with Bluetooth, Car Locator, App Support, 2 USB Ports, PowerIQ

I love this USB car charger too much it literally has everything I need in one small unit. So like I said this thing basically a Victorinox Swiss Army Pocket Knifefor you car. So what can this little guy do let's see:Dual USB charging ports(USB PowerIQ 5V/2.4A + 5V/1.5A)Bluetooth 4.2 ReceiverFM TransmitterAUX Line OutMP3 Player(Through The Non-PowerIQ USB Port)Companion Roav App(FM Frequency Modulation and Car Locator)Thats everything in this little car charger now let's talk about how it perform. Right out the box simple to use you get the SmartCharge F2 it self, Owner's Manual, and a Happy Card. When I first plugged it in I switched it to the right FM frequency that is perfectly displayed on the screen of the SmartCharge F2 and voice promoted saying "waiting to pair" and after I got my phone connected to the bluetooth SmartCharge F2 the device replied with a satisfying voice "successfully paired" and my music automatically started playing.Now comparing this to there older bluetooth receiver that Anker currently still sells Anker SoundSync Drive Bluetooth 4.0 Car Receiver, Wireless Phone Call & Music Streaming Car Kit with Built-in Mic, Music Streaming, Echo and Noise Reduction, Multi-Point Access, 3.5mm Aux Cable When I connect to this adapter I would have to guess what sound I just heard and assume I was connected with a little blue led indicator that would blink rapidly until my phone was connected and even when I had my phone connect it would show with a solid blue light and not play music automatically. Comparing the 2 devices I really love the improvements they made especially bluetooth connection are stronger and more reliable than ever, every time i leave my car weather it was on or had to turn on when I get there the blue tooth automatically connect to last devices and starts playing music all on its own.How good is the FM Transmitter?Well pretty good in my opinion with the testing I've done. On the package and in Anker's page they state you have a transmission distance of 2 m witch is 6 ft. I got around 10-12 ft. with my testing with clear audio still. Another incidences where I tried this out is on a family trip if you're using two cars and following the other car at a 2 car length distance from each other both cars can get the same FM station and simultaneously play out of the both cars making an ultimate surround sound.How's audio quality compared from AUX V.S. FM Transmitter?Well there is a difference right away if you switch from the two output sources witch both will transmit simultaneously out of the AUX out and FM out.FM out when you find a good station thats just static and you hear no other interferences from other radio stations you audio quality is how any other radio station would sound it has that radio like sound that you would get not that loud and not that much base comparing it to the AUX out, nothing can compare to a true line in connection to your speakers. But when you have AUX out and you have not music playing you hear straight static noise from the negative connection being exposed of the 3.5mm port not being fully covered even when you play music you will hear it in the background. Audio quality is best with AUX out and with a AUKEY Ground Loop Noise Isolator for Car Stereo Systems and Home Audio Systems, 3.5mm Audio Cable Included this little devices will cancel out all the static noise that you get with the SamartCharge F2 and you will have quiet and uninterrupted music listening.MP3 Player Does it Work?Yes the MP3 player does work but when I first had this it didn't work at all, had a hard time finding out why but here is the solution if your MP3 won't play music after you inserted your usb flash drive here is why. Make sure your USB drive is formatted properly to the file system FAT, FAT23, exFAT and that you music is no where but at the root of the USB drive. The reason why I couldn't get mine to work is because when I formatted this flash drive on my MacBook the default File System was "mac-os x journaled" Also you music file format has to be in .mp3 .wma .flac. wav. in order for the MP3 player to work properly. After you have everything all set on your USB drive just insert into the non PowerIQ USB port your music should start playing if not just press the middle button(phone icon) and your music should start playing. When your playing a song or skipping a song the displaying shows you what track number your on for a couple of seconds and then goes back to displaying the FM frequency that its on. Other than my little issues that I had everything work beautifully and I use the MP3 mostly everyday its like your own personal station when you don't wanna mess with your phone for music and you hate using the radio because of all of the commercials.Car Locater?When I first heard about this I thought it had to be a joke or something because you couldn't add a devices with GPS for less then $25 and I was right the only thing the car locater does with the SmartCharge F2 is nothing. The car locater relies truly on your phone the app and your phones GPS location witch you mark yourself. I think the only thing that the SmartCharge F2 does for any location finding is telling when it's connected and not connected and will give the last location when the SmartCharge F2 was last connected. Haven't used it much since you need to open the app whenever you want to use it. For the most part I just plug it in and play my music don't really have need to go into app not unless i'm change my FM frequency witch I haven't had to do and on the app you have can have 3 Preset FM station to switch back and fourth from. i'll have to do more testing on the car locater and will update my review when I can.

This works like a GEM, had it for my 2008 Prius with no info system and It was a crazy add-on. Easy to connect and never gave issues. Perfect worth the price I'd say. 1000% recommended to anyone. Multiple connections made by friends and always good.Wishing them release a screen kinda one next time : i know i'm greeedy.

PLEASE READ BEFORE YOU BUY.11/13/2017 Update: After bringing up the issues I originally had with the FM transmitter (hissing noise, a lot of static etc) they went through a bunch of trouble shooting with me... and after a few weeks they even sent me a new ANKER FM transmitter that they claim has better shielding etc compared to the older model.It worked better but not flawlessly. There were moments where I can still hear a whining noise but as soon as I started driving it would go away, and only come back after prolonged periods of times being off.Ultimately, I said screw all these FM Transmitters and Bluetooth things and got me an aftermarket stereo with bluetooth built in.. best 70 dollar invest I have made to my 2002 Nissan Altima so far.5 stars for customer service, 3.0 for the product.Review ----I drive a 2002 Nissan Altima 2.5 S and have used many bluetooth FM transmitters over time. At first, I was impressed with the product size and quality. It fits into the car eletrical very snug which is great... but that's where everything goes downhill. First, this FM transmitter is super sensitive and gets a lot of interference. And the interference doesn't sound good. It pops and snaps and messes with the bass when playing audio. Second, when you have something plugged into the usb charger, like a phone, it makes a whining noise that gains pitch when you accelerate and gets lower when you decelerate. It sounds like a space ship.I went through Ankers email support, which actually took a few days of back and froth with troubleshooting etc... they sent me a new one and it took about 3 days to arrive after a few days of emailing.. I have amazon prime so I wish it was sooner. In the mean time, I ordered another one through amazon and that one arrived. I was able to test the new one from amazon, and it gave the me same whining noise but much lower. Then the replacement anker sent me arrived and it was the same as the previous one. I ended up returning both.UPDATE:Here is the information I got Anker regarding the problem:As to the static/hissing noise issue, we have double checked this with our engineers. According to them, the static/hissing noise issue only happens with some of the vehicles. This relates to the model of the car and also the antenna's location in the car. Our engineers are now trying hard to improve our product so that it could be compatible with more cars. However, for now, we recommend you turn the volume of the car's speaker to half and turn the volume of your phone to the loudest so that the static/hissing noise will become less. Could you please try it?Apologize for the inconvenience caused and look forward to hearing from you again.Reference Ticket#71956235 if contacting a CSRElleAnkerDirect Customer Support ManagerDearSorry to bother you.
