The first version of Rider had a headset included in the box. Just found mine, it still works but I have failed to find a barrel type male DC-plug that fits so that I can charge it.

Do you know the dimension of the power plug or where it can be bought? I only need the plug (it´s charged with standard 5 V of which I have got plenty of power adaptors). It´s the same plug that is used to charge Rider 1.
