Test charge

Tried charging my S9+ with the Roidmi 3S was fine but still no fast charge.



Can change the LED color to the 4 colors available in the app or can totally turn it off.


Final thoughts
This is a must-have gadget for people who like to listen to their tunes from their phones. The Roidmi 3S connects to your smartphone via Bluetooth and to your car radio via FM frequency. And it can charge your devices and detect your car battery voltage too.

The only sad thing is that they took out the hands-free call feature that was available on the 2/2S.

    The sound quality is ok considering using FM frequency and the HU is also quite near the Roidmi.
