I have one of these, not sure if its the exact model but i can confirm. Comes with a battery.
Can also confirm (to my annoyance) that you cannot have it charging and play music at the same time. So don’t bother buying a slim angled micro usb cable like I did…
Pretty sure they have a little battery.

They missed an opportunity to use the spinning gear to generate its own power.
