After coming out of reception range (about 10 meters) and lost the Bluetooth connection, it automatically reconnects. I had never seen it with my other Bluetooth devices.
In addition, it can be used charger plugged.
The downside, however, but that does not justify not buying that issuer, the very poor quality of the supplied cable for audio (3.5mm female to two male RCA).
The female jack plug has a problem that prevents it from properly insert the male jack of the transmitter.
My rating: 9.8 out of 10.
