In the cabinet, there is the battery, a foam bag for transport providing a cushion to ask.
The battery is some weight, but that's not really a problem.
Two flat cables are provided: a short length and the other longer.
A mini USB end and the other usual USB.
They have suitable nozzles, it suffices to reverse the side of one or other of the cables, depending on what is desired to: charge the battery or charge the mobile support.
I used long to recharge the battery to a USB port of PC games or boxing.
And small to recharge the mobile support for placing one against the other battery and mobile, I can move with the two while charging while using the mobile.
This is an excellent investment of 29.99 not to be missed.
