generation 1 pencil is charging?

How do I know if my gen1 pencil is actually charging?

While charging Pencil from iPad, go to Settings > Apple Pencil ... you can check, and see % at the top of screen.

Seems if you charge in any other way, you can not check if it is charging.

Apple Support has an article online about charging.:

Charge your Apple Pencil and check the battery – Apple Support

Eg: says:

To check how much battery your Apple Pencil has left while you're using it,

 check the Today View on your iPad. Just swipe from left to right on the Home screen or Lock screen.
