nice jelly case. similar as the one exportprive sells
it comes bundled with the j3 from what i have seen but i really cant find it as a stand-alone accessory
As i said, it is a lovely "case". i cant stress this enough
Depending on your charging source, like a computer or the wall, the j3 has to be off.
However, it will turn on by itself and charge by itself. It should tell you when the battery is full (wall connected, not sure computer connected).
Also, if you have it connected to a wall, you can press play and the j3 will be able to play music and recharge at the same time. this doesnt happen when you connect it to the computer.
You can pause the radio by pressing play.
I am not sure if that is a feature of a late firmware but that is bout it.
You can not really stop the radio. i believe by pressing the play/pause button, the radio gets paused. i am not quite sure if this will reduce battery consumption.
Download the new firmware 2.23 that was released yesterday here
