Xiaomi Roidmi - Operation
As already said, the Xiaomi Roidmi born initially as a portable travel charger that, among other things, in the practical tests conducted, is able to charge the battery of the devices also very quickly (for example, with the Xiaomi Mi 4S equipped with charging Quick Charge), the Roidmi manages to be as fast as the wall adapter supplied with the smartphone.
Logically, however, if you simultaneously connect two devices in charge, the amount of current is divided on the two smartphones and, therefore, the charging times are prolonged.
Il FM compartment, then, it turned out to be interesting because of the bluetooth connectivity, but slightly cumbersome due to the installation of a dedicated smartphone application.
The app, first of all, is compatible with both devices iOS and Android (here you can download the Italian version of the application translated by the community of MIUI.it which, originally, was born only in the Chinese language) and, once installed, all you have to do is associate the smartphone with the Roidmi means Bluetooth and set the same frequency FM both on your car's receiver and on your smartphone.
La sound quality it is average of all the accessories like this; there are times when the audio is clear and clean, while there are other times when the FM frequencies they are "busy" and the audio transmission collapses, without allowing us to hear absolutely nothing.
