Anker Roav SmartCharge F0 Bluetooth FM Transmitter for Car, Audio Adapter and Receiver, Hands-Free Calling, MP3 Car Charger with 2 USB Ports, PowerIQ, and AUX Output (No Dedicated App)

The good:USB charging that keeps up with things like GPS and media usage just fine, but not a super-charger that is going to kill the battery life if used too much!A line-out option that is very high quality and loud for when there are no good FM options available.Decent range BT of ~10 ft away from the car even when doors and windows are closed. Get the full ~30 ft of range with windows open.FM quality is nice when it works. I suffer from a combo of a car receiver that isn't terribly good at managing cross-talk of stations, and being in an area with a lot of FM stations. When I have a clear channel, it works great. The trick is going more than 2-3 miles without running into another station. that said, I have one station that works in most cases, and use the line out feature when the FM isn't playing nice in the area. But again, pretty sure this is just where I live having too many stations too close together, and less a problem with the unit itself. I have had several BT to FM adapters over the years, and this has been a constant issue with my area and my car.Small compact design tucks neatly out of the way, and isn't an eye-sore or a thief magnet to people looking inside your vehicle.The bad:calling features are rather mediocre. It is much better than what is built into my car, but I still prefer to use my headset or speaker phone options. Thankfully on Android this can be managed per-device. Go to settings -> BT -> select the device -> un-check the box for calls. The result is that media will default to the last device connected, so I can listen to a show on my headset, seamlessly transition to the car stereo when the car turns on, and seamlessly transition back to the headset when the car turns off without ever having to touch anything on any of my devices. But when a call comes in, it will only ring on my headset where the call quality is best. If the headset is not on, then the phone rings by itself and I can quickly change it to speaker phone when I answer.incidental:My last couple BT to FM adapters had batteries built in. I think the idea was so that it could kick on when the key turns past ACC, and then it would be up and running by the time the car started... but it also meant it did not turn off with the car either. This does not have that issue. It kicks on and connects faster than the radio turns on, and when the car turns off it fails over to my headset in ~10 seconds. The old units I had would hang onto the connection far too long, and would cause me grief. No such issues here.

Le pongo 4 estrellas porque los dos orificios son para carga, pensé que uno lo podría usar para colocar una USB, pero no la lee. Por lo demás es muy buen producto. Tiene la opción ON OFF.

I brought this from a review it does everything the review says it would and so has awesome sound quality, the review said that it does take a while to connect with blue tooth but that it had good quality bluetooth and transmission so I figured that was the most important to me that it sounded good and it does!!! It also does take a little while to connect Lol :) I was surprised at the size it looks like a monster in pics but its fairly compact so that was good too. Oh the only fault I can find is if you want to play the radio its better to unplug it as it sets up a bit of interference with stations close to the frequency your chosen. Im guess thats because of the strong signal. So ok thats two little things for Awsome Sound also I put it in a Falcon AU with top of the line sound system I actually love the way it sounds. Anyways hope this helps anyone out there that doesnt know what to choose

Ok, I've got to admit that Anker does things right. I had an issue with a speaker a while back and they came to me with one intent...to make it right with me, and they did!!! So, with my past experience with Anker I did not hesitate to try their Bt FM Transmitter for my Jeep Wrangler. My Jeep, being an early 2003 model did not have Bt connectivity as OE equipment. This past year I have gotten back to listening to the music I grew up on back in the 70's and 80's. After using an Anker Boost speaker in the Jeep to stream music I decided that I wanted to try streaming through the Jeep's sound system. Enter Anker's Bt FM Transmitter.When I saw the transmitter (and the price!!!) it was a no-brainer for me....my brain said "ORDER IT!" I ordered it.But, I have a problem with my Jeep. The sub-woofer is rotten/blown/falling-apart/kaput/etc.,. It's got more snaps and crackles than Rice Krispie cereal has.....really!!! Anyhow, I decided that if this little cigarette lighter plug-in Bt gizmo worked that I'd go ahead and go through the expense and trouble of replacing the sub-woofer. It all depended on whether the Bt transmitter worked....or not.As it turns out I have a replacement sub-woofer ordered and will be installing it next week. The Bt transmitter works great. It sounds good, even though the speakers aren't at their best due to having to adjust the treble and bass along with the balance to get things half-way decent....I can't wait to hear the system once I've got the sub-woofer replaced! The Roav Smartcharger pairs very easily with my old iPhone-6. It is very simple to use. Find a clear frequency on the radio and tune the Roav to that frequency. It's about as easy to get going as it is to over-eat at the Golden Crane buffet!!! (GRIN)I don't know how long it will last, but for the price if I get a year or two out of it I'll feel I get my money's worth out of it (naturally I hope it lasts 20 years, but... :) ). With two USB charging ports it handles phone charging and whatever. There's even a voice that tells you when you first start up that it's trying to pair up...then tells you that pairing was successful!!! Shux, this thing's smarter than my oldest sister (but really, that isn't saying much but it is pretty doggone smart!!!!!!!!!!!!!) :)If you're looking for a Bt connection for your vehicle this one will do the trick!!!! It works great for me!!!UPDATE!!!!! I replaced my subwoofer and WOW!!!!! what a difference it makes. Tickled pink with the ROAV FM Transmitter!!!!

Does exactly what I bought it for and is very easy to use. Have had very occasional and fairly minor static noise when near stuff like power lines and construction sites, but nothing to really complain about. Especially when considering the fact that this unit comes with a headphone jack you can use to connect to your stereo rather than the FM transmitter. It's pretty good!
