Ye it's for [this](https://www.bose.com/en_us/products/speakers/speaker_accessories/soundlink_revolve_charging_cradle_acc.html#v=soundlink_revolve_charging_cradle_acc) thing I believe

For a charging cradle if you want to buy one, it’s an optional extra.

It's not only for charge, it's a complete usb port. I have already connected my revolve to my computer using that

sorry had to cross out the serial but he said there could be some base to connect to? i’m not sure but can someone help 🙏🏻🙏🏻 my old man is almost 73 and loves his new speaker and wants to make it as cool as possible

my dad was wondering what this bottom part was for on his new sound revolve link 2?
