Will the HomePod have a built in battery? If so will the lightning charger charge the speaker battery?

Portable music speakers are out there, its going to be a hard market for apple to capture. The home pod can change the music game for the whole world if it had a battery and the battery can be charged via the lightning cable.

It would really make the users happy if there was a USB port on the HomePod that you can plug your iPhone in to charge/play audio through.

Since the new MacBook Pro has a USB-C. An added advantage could be a universal USB-C port to charge battery/connectivity to Mac
