what does the battery icon do on a Lumia 640 when it is being charged

While phone is plugged in for charging up where the battery icon is to show if it is charging or not. It shows a blinking plug, does this mean it is charging or that the usb plug isn't working correctly?

It shows a blinking plug. Don't worry that's how it shows.
