leutwyler.andre6 years ago011Is it possible to supply the player with power via a USB cable? Or do I have to use the mains cable with 12 volt adapter?Show in original language (German)Rguntlis6 years ago000It only works with the 12V charger supplied. Fortunately, we have a power socket in the car where we keep both devices in operation while driving. Otherwise, it's enough for a maximum of 3 hours of operation.Show in original language (German)Comment
