Unfortunately, I can't answer the question because I always leave the cable connected to the device. That way I don't lose the cable... But it definitely has a battery. I use it for hours on end and haven't yet found out how many hours the battery would last.
You can already operate the part on the mains. But the battery will be damaged. You don't have the mobile phone permanently connected to the mains. Treat the receiver the same as your mobile phone and you will enjoy it for a long time. Greetings Christoph
