Make Samsung U3 play music while charging. How?

Question

Samsung

Actually, subject. In this player, the battery died (enough for 5 minutes), but I want to listen to the radio (the Internet is not an option). When connected to a computer, it starts charging and goes into mass storage mode and is blocked. How to make it charge, but not block, can remove the battery and somehow make stationary power instead of it (from the same usb for example)?
Has anyone had a similar experience?

Answer 1

Try to connect through a similar adapter:

As far as I understand, there will be no USB hub, but power will be supplied.

Answer 2

Plug it into an outlet.
