I chose him because he has both battery and charging cable.
One can operate with or without cable him so.
You know what I mean in some other devices that the battery is empty and then times the shaver does not cut as well, you of course have to wait some time until the battery is sufficiently charged again, etc.
The falling away everything here.
How long does the battery I can not say because I have the device only just over 4 weeks.
I'm going to report me to be something on the device is defective.
