I think that's an iPod mini (small monochrome screen and colorful casing). Some older iPod models need to be connected to an Apple power adapter (which came with the iPod) as the last step of doing a Restore (and maybe an Update). That may be what you are seeing on the iPod's screen. It is not related to charging the battery. The USB port on computer does not work for this purpose. So, if you have the power adapter that came with the iPod, or another Apple USB power adapter (like the one for iPhone or iPad), connect iPod to it. Third-party power adapters may or may not work.
If that's not possible, you can try doing a Reset (restart of iPod), but it may come back to the same screen
