Review on 🚗 Enhance Your Car Audio Experience with Bluetooth FM Transmitter:Wireless Car Radio Adapter, MP3 Music Player Car Kit with Hands-Free Calling, QC3.0 Charge, LED Backlit, TF Card/USB Connectivity - Compatible with All Smartphones Audio Players by Jacob Jefferson

First of all this transmitter is a lot smaller than I thought but I am very satisfied as where they placed the extra power socket is in one small cabinet next to my gearbox, and this transmitter fits perfectly in it. When tuning, all I had to do was plug it in and find a radio station that wasn't being used. Once this was plugged in and set up, I simply connected this transmitter using my bluetooth phone. For convenience, I've set up a channel for this on my radio so I can answer the phone more easily or even listen to my own music when I'm on short trips or just driving. My car doesn't have USB sockets. As it occupies the outlet I use to charge my phone I'm very happy that it has 2 USB outlets which I can still use to charge my phone and someone else's phone if I have a passenger. It actually charges my phone much faster than the plug I bought which only charges my phone. If I have a phone on a phone mount I can either take calls from there or just press a button and I can hear people through my speakers. The rainbow light is just a bonus, but it can illuminate the place quite well, which was helpful when I was trying to plug in my phone to charge it.
